PRODUCT OVERVIEW
The dCS Delius is derived from our award winning dCS Elgar Plus, the world’s
first 24/192-DSD audiophile D/A converter. Delius has been designed to closely
approach the ultimate performance level of Elgar Plus, consistent with a lower
parts cost.
All dCS DACs feature our patented dCS Ring DAC technology. This unveils the
intricate low level musical detail that is dCS’ hallmark.
Delius will accept digital data at 44.1kS/s from your CD player and interpolate
the 16 bits, giving your CD collection a new lease of life. Delius will also convert
24 bit 96kS/s data from DVD players, revealing the increased depth and
spaciousness inherent in the more complex source information. With the current
software version, Delius also has the ability to act as a master clock for your
transport, increasing the clocking precision of the overall system.
Units fitted with the IEEE 1394 interface option can convert DSD data (a single
bit data stream, sampled at 2.822MS/s) from a suitably equipped Upsampler or
SACD player to extra wide-band audio, taking advantage of the extended
bandwidth inherent in the DSD format.
All dCS DACs use the same digital processing engine running the same DSP
code. The extensive use of programmable logic makes dCS products extremely
flexible and easy to upgrade. You can load updated Delius software from a dCS
CD using a CD player, or dCS service agents can download software to the
SUC port, using a PC.

FREDERICK DELIUS (1862 –1934)
The dCS Delius is named after Frederick Delius, the English composer. Fritz
Theodor Albert Delius was born of German parents in Bradford, Yorkshire on
th
January 29 , 1862. He changed his name to the more English-sounding
“Frederick” in 1902.
His father, a wool merchant, encouraged him to play the piano and violin,
although he had other plans for his son’s career. After college, Fritz represented
his father’s business for three years, travelling through Sweden, Norway,
France and Germany. This lifestyle gave Delius an enduring cosmopolitan and
romantic outlook that is reflected in his musical style.
His consuming interest in music developed, to the detriment of his
responsibilities to his father’s wool business. In frustration, his father sent him to
manage his orange plantation near Jacksonville, Florida, USA . Young Fritz was
deeply affected by the singing of the local slaves and the beauty of the unspoilt
Florida scenery. This environment was the inspiration for his Florida Suite. He
bought a piano and concentrated on his music, at the expense of the orangegrowing business.
In 1885 at the age of 23, Fritz spent a year teaching music in Danville, Virginia.
The following year, he finally persuaded his father to finance his musical studies
at Leipzig Conservatory, where he met and became fast friends with Edvard
Grieg, the Norwegian composer.
He moved to Paris in 1888, where he found himself among kindred spirits such
as Ravel and Gauguin. His love of the city inspired him to write Paris: The
Song of a Great City.
In 1897, he and German artist Jekla Rosen settled in the quiet village of Grezsur-Loing, near the forest of Fontainbleau, in France. They married seven years
later. Delius’ music was brought to the British public by the conductor Sir
Thomas Beecham.
The major influences on Delius’ work were the everglades of Florida, the cool
green forests of northern Europe and the snowy fjords of Norway, a passion he
shared with Grieg. He loved the tranquillity of the countryside, normally avoiding
the bustling cities, except for his extended sojourn in Paris. His love of nature is
epitomised in pieces such as On Hearing the First Cuckoo in Spring, Brigg
Fair: an English Rhapsody, Over the Hills and Far Away, In a Summer
Garden, Summer Night on the River, Sea Drift and A Song Before
Sunrise. His stage works include Koanga, a love story strongly influenced by
Afro-American song and dance.
During the First World War, Frederick and Jelka were forced to retreat from their
idyllic Grez to take refuge in England and Norway. After the war, they returned
to Grez, and his work continued apace.
In 1922, Delius displayed the first symptoms of infection with syphilis. This
marked the beginning of a slow physical degeneration, leading to blindness and
paralysis in his later years. His mind was undimmed by his illness, and he
continued composing. Six years later, he was reduced to dictating to his
assistant, composer Eric Fenby. His work during this difficult period is widely
considered to be some of his best.

His illness also took its toll on Jelka, the strain of caring for him ruined her
th
health. Frederick Delius died on June 10 1934 in Grez, attended by his
devoted Jelka. He was buried in Limpsfield, Surrey, England.

Step 1 – Selecting a Digital Input
Switch on the source equipment. If appropriate, load a disk / tape and set the
machine in PLAY mode to ensure it is generating a digital audio data stream.
Choose one of the following three sections:
Connecting to a Single AES or SPDIF source
Most source equipment (such as CD transports, DVD players) is fitted with a
single wire digital output, usually on an RCA phono connector.
do this:
do this:
Connect your source equipment to the matching input on the Delius rear panel
using a suitable cable.
Press the Input button repeatedly until your chosen input is displayed on the
input indicator, to the right of the display. This will be either AES 1, AES 2,
RCA1, RCA2, TOS, or BNC.
The unit will lock to the source, displaying in sequence Locking, d xxx (the
sample rate) then the default display (probably 16/44, depending on the Disp
menu setting and the source format).
Connecting to a Dual AES Source x
do this:
Check that your source equipment is capable of Dual AES operation.
do this:
Connect the AES 1 (or AES A) output on your source equipment to the AES 1
input on the Delius rear panel and the AES 2 (or AES B) output to the AES 2
input, using two XLR cables. Ensure the cables are not swapped.
do this:
Press the Input button repeatedly until both AES 1 and AES 2 input indicators
are lit.
The unit will lock to the source, displaying in sequence Locking, d xxx (the
BASE sample rate) then the default display (probably 24/192 depending on the
Disp menu setting and the source format).
Connecting to an IEEE 1394 DSD Source
(This section applies to units fitted with the IEEE 1394 interface option.)
do this:
do this:
do this:
Check that your source equipment (probably an SACD player or a dCS
Upsampler) is capable of DSD operation over a 1394 link, generates a 44.1kHz
wordclock and is set up correctly.
Connect one 1394 output on your source equipment to one 1394 input on the
Delius rear panel. Also connect the wordclock output on your source equipment
to the Wordclock In connector on the Delius rear panel.
Press the Input button repeatedly until the 1394 input indicator is lit.
The unit may display Wait ..., No-WClk or Search.. messages before finally
settling down to the source name (probably Purcell or Verdi). If necessary, use
the Input button to select the 1394 source you want to listen to. You may find
Delius settles more quickly if you set it to 1394 mode before setting the source
to DSD mode (or switching the source on).
do this:
Proceed to Step 2.

Step 2 – Connecting the Analogue Outputs
Choose one of the following two sections:
Using a preamplifier
x
do this:
Set the preamplifier volume control to minimum.
do this:
Connect either the balanced (XLR connectors) or unbalanced (RCA phono
connectors) outputs on Delius rear panel to matching line level inputs on your
preamplifier (probably labelled CD or AUX).
do this:
Turn Delius rotary control clockwise to set the Volume to maximum (Vol 0.0 on
the display).
do this:
Slowly increase the preamplifier volume until the music is at the right level.
Using a power amplifier directly
x
do this:
Turn Delius rotary control counter-clockwise to set the Volume to minimum
(Vol -60.0 on the display).
do this:
Connect either the balanced (XLR connectors) or unbalanced (RCA phono
connectors) outputs on Delius rear panel to matching inputs on your power
amplifier. Switch on the power amplifier.
do this:
Turn Delius rotary control slowly clockwise until the music is at the right level.
A basic setup with a CD player is shown in Figure 1.
do this:

Step 3 - Setting the Output Level
If the preamplifier volume setting for a comfortable listening level is too high or
too low, you may need to change the Output Level setting. Similarly, if you are
driving a power amplifier directly and Delius Volume setting for a comfortable
listening level is higher than –10.0 or lower than –20.0 try changing the Output
Level setting.
IMPORTANT!
do this:
Do not play music at a high level while changing the Output Level setting.
Press the Function button once, then press the Mute button repeatedly until
the display shows Out:2V or Out:6V. If the Volume setting is too high, press
the Select button to change to Out:2V. If the Volume setting is too low, press
the Select button to change to Out:6V.

Step 4 - Using Delius in Master Mode
If your CD transport (or other source equipment sampling at 44.1kS/s) has a
Wordclock input, you can reduce the jitter in your system by using Delius in
Master mode and slaving the source to it. If not, you can miss out this step.
IMPORTANT!
do this:
do this:
You can only use Master Mode if your source sample rate is 44.1kS/s.
Connect Delius Wordclock Out connector to the wordclock input on the source
equipment. You may need to set the source equipment to slave to wordclock.
Press the Function button to open the menu, then repeatedly press the Mute
button until the display shows MS:Slav. Press the Select button repeatedly until
do this:
the display changes to MS:Mastr.
Allow the menu to time-out.
IMPORTANT!
If you are using an Upsampler, this MUST be set to convert a 44.1kS/s source
to either 44.1kS/s, 88.2kS/s, 176.4kS/s or DSD. If not, Delius will be unable
to lock.
The equipment will take several seconds to re-lock and settle down, then Delius
will unmute.

Using the Function Menu
The Function Menu gives the user access to a wide range of additional
features. It also allows new features and performance enhancements to be
added at a later date by software upgrades.
Opening the Menu
The Function Menu is controlled by three buttons:
•
•
•
the Function button opens the menu and doubles as the Select button.
the Step → button pages forward through the Menu – referred to in the text
as the Step button.
the ← Step button pages backward through the Menu – referred to in the
text as the Step Back button.
If you have a dCS Remote Control, you can use this to access the menu:
•
•
•
•
the Function button opens the Menu and doubles as the Select button.
the ↑ button pages forward through the Menu - the Step button.
the ↓ button pages backward through the Menu - the Step Back button.
to control an Upsampler instead of a DAC, first press the Purcell button to
turn the blue LED on.
When you first open the Function Menu, the display will show Menu.
Successive presses of the Step button page through the Menu. You cannot go
directly to any particular page, but must enter at the top of the Menu and then
page through until you reach the page you want.
Types of Menu Page
There are three types of page in the Menu - Parameter Pages, Information
Pages and Test Pages.
Parameter pages allow the user to check and also change the current settings
of the operating parameters, for example Filter. When a parameter page is
displayed, the first press of the Select button shows the current setting.
Subsequent presses of the Select button change the page setting.
Information pages display information about the unit, for example Software
Issue. When an information page is displayed, pressing the Select button
displays the information held on that page.
Test pages allow the user to initiate a number of useful routines, for example
Channel Check. When a Test page is displayed, pressing the Select button
starts the test routine.
Closing the Menu
There are two ways to close the menu and return to normal operation. The
easiest way is to wait 5 seconds for the unit to time-out and revert to the
standard display. Alternatively, use the Step button to page forward until the
display shows End and then press the Select button once.
If the unit times out before the operation in hand has been completed, simply reenter the menu, page forward (or backward) and continue where you left off. If
you find the 5 second time-out difficult to use, you can extend it to 30 seconds
by changing the TimeOut setting to Long.

Menu Sequence
Use the flow chart (page 20) or the Control Summary sheet to guide you
through the Menu more quickly.
The following explanation deals with the Function Menu pages in the sequence
2
they occur in the Menu . The use of each page is shown on an individual basis,
with the last operation being closing the Menu. After you have become more
familiar with the Menu, you will find it more convenient to perform all the
Function Menu operations in one go before finally closing the Menu.
Filter – Anti-Imaging Filter Setting
Delius offers a choice of 4 interpolation filters for 5 sample rates (32kS/s,
44.1kS/s, 48kS/s, 88.2kS/s and 96kS/s) and 6 for two (192kS/s and 176.4kS/s).
The filters offer differing responses. In each case, Filters 1-4 are symmetrical
filters (with time response before a transition the mirror image of time response
after). Filter 1 offers the sharpest cut-off, least Nyquist imaging but longest
energy smear. Filter 4 gives the gentlest roll-off (usually with significant Nyquist
imaging) but the shortest transient response with least energy smear. Filter 5 is
a Gaussian filter, and Filter 6 is an asymmetrical filter – there is almost no time
response prior to the initial step.
For units fitted with a 1394 interface, DSD mode also offers four filters, but
these are intended to progressively reduce the out-of-band noise level. Filter 1
generally gives the widest bandwidth, but results are system dependent – if
your system gives undesirable effects with Filter 1, try (in this order) Filter 2
then Filter 3 then Filter 4. These reduce the out-of-band energy at the
expense of reduced bandwidth. Filter 4 is really intended for metering
applications, not for listening.
Delius remembers the last filter selection made for every sample rate. So, if you
choose Filter 4 for 96kS/s and Filter 6 for 192kS/s, these separate settings will
be stored and loaded when the incoming sample rate changes (usually when
selecting a different input or changing the Upsampler settings).
Selecting a Filter
x
We encourage you to experiment with the filters, to find the one that sounds
best for your particular application. Do not assume that one filter is best for all
3
applications!
do this:
Assume for the purpose of this illustration that the sample rate is 96kS/s and
Filter is currently set to Filter 1. Open the Function Menu and step through
until the display shows Filter 1.

3
A minor software update may change the order of the menu items or add an option. If this happens, the
Control Summary sheet may be updated before the manual.
The reports we receive from users suggest that Filter 2 is well suited to some classical music, and that Filters
3 and sometimes 4 suit rock. Filters 5 and 6 are too new to have reports on, although the user may wish to
refer to “Effects in High Sample Rate Audio Material”, by M.J.Story, R.Kelly, D.A.McLeod, M.N.Harris,
th
presented at the 20 Tonmeister Tagung at Karlsruhe in November 1998. This paper is available from the

Press the Select button slowly several times. The display will in turn show:
Filter 2, Filter 3, ... and finally Filter 1 again. Select the filter you want to use
then wait for the Function Menu to time-out.
There is a slight delay whilst the unit changes filters, during which it will not
respond to further button presses. Selecting the most appropriate filter is simply
a matter of flipping through the options as you play a CD and choosing the one
that you think sounds best. Try listening for changes in imaging, ambience and
low level information, bass definition and vocal clarity.
You can change filters more quickly from the listening position using the Filter
button on the Remote Control, see page 44.
MS – Master/Slave Operation
This is set on a per input basis, and determines whether that input acts as a
master or a slave. The options available (independently, for each input) are:
MS:Slav
(Slave) In slave mode (most DACs operate in this mode)
the PLL locks to the incoming signal, and tracks it. This
setting is not available in DSD mode.
MS:Mastr
(Master) In master mode, Delius acts as a master clock,
and outputs an autonomous 44.1kHz clock on
Wordclock Out. This might go, for example, to a CD
transport. The CD transport output is then locked to the
DAC VCXO, and the DAC only has to decode the data
coming in – it knows the clock frequency.
MS:Sync
In sync mode, the PLL locks to a master clock (or other
clock source) connected to Wordclock In while taking
data from the selected input. The source must also be
locked to the master clock, or generating the clock. If the
Wordclock is not at a standard frequency, is out of
capture range or is a “superclock”, the unit will display
Locking…, Fs=??? for 1 minute, then Revert to Slave
for 10 seconds and reset itself to MS:Slav.
There are some restrictions on master mode operation. The source (usually a
CD transport or player) must run at 44.1kS/s ONLY. Delius may be used in this
mode with an Upsampler, but the Upsampler output must be set to 44.1kS/s,
88.2kS/s, 176.4kS/s or DSD.
Setting to Master Mode
x
If you wish to use master mode (we recommend this for CD transports that will
accept a 44.1kHz word clock), then do the following:
do this:
do this:
do this:
do this:
Connect the CD transport (or other source equipment) to Delius and select that
input.
Connect Wordclock Out to the wordclock input on the CD transport.
Open the Menu and step through until the display shows MS: Slav.
Press the Select button to change the display to MS: Mastr.
(Run through this sequence again if you want to change back to MS:Slav.)
If a source is connected and selected, Delius will display d 44.1, then MS:Mastr
and 44.1kS/s alternately for about 10 seconds. After that it will enable its
outputs and is ready for listening.

If you are using an Upsampler set for 176.4kS/s Dual AES output, select the
Dual AES input. The displays will then be d 88.2, then MS:Mastr and 176.4kS
alternately for about 10 seconds.
If you are using an Upsampler set for DSD output and your Delius is fitted with a
1394 interface, select the 1394 input. The displays will then be Wait…, then
MS:Mastr and 1394 alternately for about 10 seconds.
If you attempt to use a input sample rate that is not a multiple of 44.1kS/s (for
example 192kS/s), the unit will detect this and the following message will scroll
across the display:
“Can’t Use Input Frequency in Master Mode. Press ..... Button to Slave”
If you press the button mentioned in the scrolling message (Function for Delius,
Phase for Elgar), the selected input will be reset to Slav.
If you get stuck, use the Rst Sync menu to reset the unit.

Dual AES – Dual AES Mode
The Dual AES interface was developed by dCS to allow 88.2 or 96kS/s data
streams to be recorded on equipment designed for 44.1 or 48kS/s operation. It
allows a stereo pair of 24/96 data to be recorded on a 4-track digital recorder.
Dual AES mode has become a de-facto standard, appearing on an ever
increasing array of products. Since then, we have developed the Dual AES
interface further to operate at up to 192kS/s, doubling the available audio
bandwidth a second time.
All dCS non-optical single-wire interfaces are capable of 24/96 operation, but
some of our audiophile customers have told us there are extra sonic
improvements to be gained from using Dual AES for 24/96 instead. The reason
for this is certainly not obvious – the digits appear to be the same, it is not
related to jitter.
For 24/192 operation there is no choice but Dual AES. Even our high-speed
single wire interfaces are not currently fast enough.
There are certain requirements for successful Dual AES operation. Obviously,
the source must generate a true Dual AES data stream, not two single AES
outputs. The two cables should be similar in length (less than 3m difference).
The two cables must be connected the right way around or the channels will be
swapped.
Changing inputs between single wire and Dual AES may cause the DAC to
default to single AES mode. To avoid this problem, the Dual AES page offers
the following four options:
Off
Disables Dual AES mode for when no Dual AES capable
sources are in use.
On
Allows Dual AES mode to be manually selected from the
front panel Input button (see page 36) or the Remote
Control, (see page 44).
Auto
Delius detects single wire or Dual AES mode from the
message flags in the data stream and sets the mode
accordingly. If a Dual AES source is detected but only
one wire is connected, it will lock to the source as single
AES but flash either the AES1 or AES2 indicator to warn
you that one cable is missing.
Lock
If both AES 1 and AES 2 are active, selecting either AES
input in this mode forces the unit into Dual AES mode. If
only one wire is connected, the unit warns you of this by
flashing the indicator for the missing wire. Lock mode is
particularly useful when using an Upsampler –
upsampling everything to 176.4 or 192kS/s Dual AES. In
this case, leave Delius set to Lock mode and select
inputs on the Upsampler.
IMPORTANT!
Note that not all Dual AES capable equipment sets the message flags
correctly. If this is the case, do not use Auto mode. You can use it with
confidence on dCS equipment.
do this:
do this:
To select the Dual AES mode you require, open the Function Menu and step
through until the display shows Dual AES.
Press the Select button repeatedly and the display will cycle through the
options. When you reach the one you want, wait for the menu to time out.

If you have run the Channel Check test and decided the channels are reversed,
you can swap the channels back digitally as follows.
do this:
do this:
Assuming the unit is set for swap off, open the Function Menu and step through
until the display shows Swap:Off.
Press the Select button once.
The display will change to Swap:On.
do this:
Run through this sequence again if you want to swap back.
The Swap setting is NOT remembered when you switch off. If your channels are
swapped, check the wiring between units and correct the error.
Disp - Default Display
This feature allows you to choose what Delius displays when music is playing
do this:
do this:
Open the Function Menu and step through until you come to the Disp page.
Press the Select button repeatedly and the display will cycle through the
following :
Disp:Vol
The display reverts to Volume after time-out (e.g.
Vol -12.0).
Disp:Fs
The display reverts to Sample Rate after time-out (e.g.
44.1kS/s).
Disp:Fs+
The display reverts to Input Bits + Sample Rate (format)
after time-out (e.g. 24/192). If receiving digital silence, 0
input bits will be correctly displayed.
Disp:Inp
The display reverts to the selected input after time-out
(e.g. AES1).
Choose whichever you prefer and wait for time-out.
Out - Output Level
The Analogue Output levels should be set to suit your system – there are two
levels: 6V (high) or 2V (low). The difference between the two settings is 9.5dB.
For best results, Delius’ volume control should be set to no lower than –20.0 for
normal listening levels with typical music. We suggest you start with 2V and
increase the level to 6V if this is inadequate.
Before changing the output level, please ensure you are not playing music at a
high level – the extra 9.5dB is noticeably louder. To change the setting (starting
from 2V):
do this:
do this:
Open the Function Menu and step through until the display shows Out: 2V.
Press the Select button once. The display will change to Out: 6V.
do this:
Run through this sequence again if you want to change back to 2V.

Bright x - Display Brightness
This adjusts the brightness of the main display, with settings between 7
(brightest) and 0 (off, unless something is touched).
do this:
Open the Menu and step through until the display shows Bright x, where x is a
number between 7 and 0.
do this:
Press the Select button repeatedly and the display cycles through Bright 7,
Bright 6, ......., Bright 1, Bright 0 and back to Bright 7.
After time-out, a setting of Bright 0 blanks the display unless the unit is not
locked. Operating any control or locking to a source while in this mode turns the
display back on momentarily.
Phase – Overall Phase
This option allows you to invert (reverse the phase of) both channels to correct
a system phasing error.
do this:
do this:
Assuming the unit is set for phase normal, open the Function Menu and step

The PHSE indicator will light and the display will change to Phse:Inv.
do this:
Run through this sequence again if you want to change back.
De-Emph - De-Emphasis Behaviour
Recording with high frequency emphasis is a hangover from the days of
recording onto noisy magnetic tapes. To combat tape hiss, the high frequency
part of the music was recorded at a higher level (pre-emphasis). The high
frequency response was corrected at playback by a de-emphasis filter, reducing
the hiss level as well. Digital radio also can use CCITT pre-emphasis, to help
keep the bit rate down.
Some early CDs were recorded with 50/15µs emphasis, but more recent disks
have a flat frequency response. The emphasis used during recording is
encoded in message flags, buried in the data stream. On some disks, these
flags are incorrect, resulting in a bumpy frequency response. Delius can apply
de-emphasis for sources with sample rates of 32, 44.1 or 48kS/s – it is not used
for 96kS/s or SACD recordings.
The options available are:
Off
Applies no de-emphasis and ignores message flags.
Auto
Automatically applies the de-emphasis curve indicated by
the message flags in the data stream.
50/15us
Applies 50/15µs

Global – Global/Local Volume
Delius can store Volume settings in two ways:
•
•
Applying the same Volume setting to all inputs (Global volume).
Using different settings for each input (Local volume, or Input specific). This
is useful where the average loudness (and so the preferred Volume setting)
changes from source to source.
To change this setting:

PLL - PLL Tracking bandwidth
In slave mode, the PLL (Phase Locked Loop) synchronises Delius’ internal
crystal clocks to the incoming data stream. The system runs through two
different modes while locking. The final mode (fine lock) has a very narrow
bandwidth which rejects jitter generated by the source. This is the normal PLL
setting and gives best results with a stable source. It takes about 6 seconds to
lock.
Some CD players (even some very expensive ones!) generate a high level of
jitter and this can cause Delius to intermittently lose fine lock and mute the
Analogue Outputs. This menu option forces the PLL to stay in a wide-band
mode, allowing it to track larger variations in the source sample rate. In this
mode, the unit locks in less than 100 milliseconds.
do this:
To change the setting:
Open the Function Menu and step through until the display shows PLL: Fine or
PLL: Wide.
do this:
Press the Select button to change between these two settings. Select PLL:Wide
if you are having locking problems.
If you are using Delius in master mode or with a Master Clock, the PLL should
be set to PLL:Fine, otherwise the jitter improvement will be lost.
NAud - Non Audio Muting
Delius is normally set to mute if the Non-Audio message flag in the incoming
data stream is On – identifying the source as a corrupt data stream, CD-ROM or
other non-audio format.
We have found that some audio CDs actually have the Non-Audio flag set! To
listen to such disks, the automatic muting must be TEMPORARILY disabled.
IMPORTANT!
Listening to a CD-ROM is very unpleasant and can cause damage to your
ears, power amplifier and loudspeakers. Use this mode with care. You
should turn Non-Audio Muting back on as soon as possible – we advise you
not to leave Delius in this mode.
Override Non-Audio Muting
x
The most convenient way to over-ride the Non-Audio muting for individual
tracks is as follows.
do this:
When NonAudio is displayed, press the Mute button. Delius will play the track
normally. Press the Mute button again to mute the outputs and restore NonAudio muting.
The over-ride is cancelled at power down or when the unit re-locks, avoiding the
risk that the unit will be left for extended periods without protection.

Inverted
A second burst of noise appears on both channels with the right channel
inverted for several seconds.
Done
This is displayed briefly at the end of the test.
If both channels are in-phase the first burst of noise will produce a stable central
image but the second burst will not. If one channel is out of phase, the second
burst will produce a stable stereo image but the first will not.
If there is a phasing error, check for wiring errors from the unit output onwards.
You cannot correct this error on a dCS DAC using the Phase feature as this
inverts both channels.

CDUpdate – Software Update By CD
Current software for dCS Elgar Plus, Elgar, Delius or Purcell and all Verdi, La
Scala or Verona software features a CD Update menu page. You can update
the software inside any of these products loaded with CD Update software
quickly and easily from a CD supplied by dCS.
IMPORTANT!
Please follow the latest update instructions supplied with the CD. The
following is for guidance only.
You will need a standard CD Transport, a CD player or a dCS Verdi to play the
CD. A few CD players are not suitable because they upsample to 48kS/s or
change some of the data bits in other ways (one example is the ML37). Don’t
worry - the CD Update routine detects these and stops, preventing any changes
to the internal software.
do this:
do this:
If you are updating a dCS Upsampler or DAC:
Connect an AES or RCA digital output from the Transport to the Upsampler or
DAC and select the input you have just connected. Disconnect any 1394
interface cables.
If you are updating a dCS DAC connected to the Transport through another
device:
Connect an AES or RCA digital output from the other device to the DAC and
select the input you have just connected. Set the other device to bit-for-bit mode
(Cloning on a dCS Upsampler). Disconnect any 1394 interface cables.
If in doubt, connect the DAC directly to the transport.
do this:
do this:
do this:
do this:
If you are updating a dCS Verona:
Disconnect ALL cables from the unit, except the power cable. Open the Menu
on the unit to be updated and step through until the display shows CDUpdate.
Make sure the transport is in STOP mode.
Press the Select button to start the routine.
When the unit displays Cable, connect a BNC cable from the Ext Ref Input to a
BNC SPDIF digital output on the transport. The unit will lock to the transport,
then display Wait.
If you are updating a dCS Transport, the Transport plays the CD and updates
itself, missing out some of the early steps. Disconnect any 1394 interface
cables.
do this:
do this:
do this:
do this:
do this:
For all dCS units:
RELAX! The update procedure is easy.

Insert a dCS CD (containing software for the unit you want to update) into the
transport, making sure it is in STOP mode.
Open the Menu on the unit to be updated and step through until the display
shows CDUpdate.
Press the Select button to start the routine.
The unit will display Wait while it prepares the flash memory for the update.
After 3-4 minutes, the unit will scroll Please Start CD.
do this:
IMPORTANT!

If there is anything wrong with the dCS CD that has been loaded or it does not
match the product, the unit will display Wrong! or Wrong CD or No Index and
revert to normal operation. Don’t worry – the internal software is unchanged.
Check the CD for dust or scratches.
If it is not a dCS CD at all, the unit will keep repeating Please Start CD, for
about 30 seconds or display Wrong CD and then revert to normal operation.
If the data is correct, the unit will display Track n, where n is a number.
do this:
You can move the Transport on to track n, or wait for it to get there of its own
accord.
If the unit has to wait for the right track, it will display Found Track 1, then
Found Track 2, etc, until it finds the right one. Vx.xx will appear on the display
(this is the new software issue number). If the unit displays No Track, repeat
the procedure but manually advance the transport to track n.
Next, the update progress is displayed in one of the following formats:
•
•
The display counts up from 0% 0/7 to 99% 0/7, displays Copying, counts
up from 0% 1/7 to 99% 1/7, displays Copying and so on until the last
section is loaded and copied. Some models may use less than 8 sections.
A moving dot counts down slowly from about 3 to 0.
After about 15 minutes, the update is complete and the unit will reboot itself.
do this:
do this:
If the CD is still playing, you can stop it now.
If the unit being updated has a 1394 interface, wait until the unit has settled
(about 30 seconds), switch it off for 10 seconds, then on again.
If the unit detects no change in the 1394 interface code, it will boot up as usual
and be ready for use.
If the 1394 interface code has been updated, the unit will load the new code into
the flash memory on the 1394 interface board – this takes about 10 minutes.
While this is taking place, the unit will display a progress bar. Next the unit will
display in sequence: Done 5, Done 4, …, Done 1 then reboot itself again.
The unit is ready for use.
OOPS!
If the CD transport stops or becomes disconnected during an update, don’t
worry! The original software is backed up inside the unit. Proceed as
follows:
The checking routine will find a sequencing error and Non Seq or Bad CD! will
appear on the display.
do this:
Turn the power off and on to reboot. This message will scroll across the display:
Bad CheckSum – Press Function button to attempt recovery
or
Bad CheckSum – Press Mute button to attempt recovery
or
Bad CheckSum – Press Menu button to attempt recovery,
depending on the model.
do this:
Press the appropriate button once.
The original software is retrieved from the internal backup while displaying
Wait... . This may take a few minutes. When recovery is complete, the unit
re-boots.
do this:
Run the CD Update routine again to load the new software.

The choices for a standard Delius are AES1 (XLR), AES2 (XLR), Dual AES
(AES 1 + AES 2 simultaneously on 2 x XLR), RCA1, RCA2, Toslink or BNC.
Dual AES is available only if both AES1 and AES2 inputs are connected to a
Dual AES source.
An IEEE 1394 interface is available as an option. Use the Input button to select
one of the sources connected to the 1394 interface.
The Input button doubles as the Menu Step Back button, used for paging

Mute Button
do this:
(Step)
If the unit is locked to a digital source, press the Mute button to mute or unmute
the Analogue Outputs. The Mute indicator will light when the outputs are muted.
If the unit is not locked to a digital source, the Analogue Outputs are
automatically muted, the Mute indicator is lit and the Mute button has no effect.
do this:
See NAud on page 29 if you need to over-ride an incorrectly set Non-Audio flag
on a disk or tape.
The Mute button doubles as the Step button, used for paging forwards through
the Function Menu (see page 21).
Status Indicator
x
This consists of 4 indicators:
•
•
•
•
PWR is lit when power is connected and the unit is turned on.
STBY is lit when the unit has been placed in Standby mode. The PWR
indicator will also be lit but all other indicators and controls will be inactive.
The Analogue Outputs will be muted and the unit will be operating in a
reduced power, “keep warm” condition. To return to normal operation, press
the Power button. If power is turned off or fails, Standby mode is cancelled.
MUTE is lit whenever the Analogue Outputs are muted. This occurs if you
have pressed the Mute button during normal operation or if the unit is not
locked to a digital source (displaying No Input). If a non-audio source such
as a CD-ROM is being played, Delius will normally mute automatically to
protect your ears, power amplifier and loudspeakers.

time.
Function Button
(Select)
Press the Function button to open the Function Menu (see page 21) and
change or select settings in the menu.
Rotary Control
x
This control is dual function. In normal use, it sets the Volume or Balance, but

For unbalanced equipment, use the Unbalanced Outputs with good quality,
screened, RCA phono audio cables. The Unbalanced Outputs are very high
quality! It is much better to use these for equipment with a single-ended input,
than to use half of a balanced output. Doing so may cause ground loop hum
pickup.
AES/EBU Digital Inputs
The AES 1 and AES 2 inputs may be used individually for digital signals with
sample rates up to 96kS/s. The data format is AES3.
In Dual AES mode, both inputs must be used together. The Dual AES interface
allows a 192, 176.4, 96 or 88.2 kS/s 24 bit signal to be encoded as two
standard 96, 88.2, 48 or 44.1 kS/s 24 bit AES data streams respectively. Delius
decodes the dual data stream and converts it to wide band analogue. See Dual
AES on page 25 for more information.
IMPORTANT!
Please ensure the two AES inputs are correctly connected to the source for
Dual AES operation or the channels will be swapped. This usually involves
connecting AES 1 (or AES A) on the source to AES 1 on Delius and AES 2
(or AES B) on the source to AES 2 on Delius.
Use with 110 ohm screened, twisted pair cable designed for digital audio or RF.
Do not use unscreened cables as they may pick up interference from other
appliances.
SPDIF Digital Inputs
The RCA1, RCA2 and BNC inputs are used individually for digital signals with
sample rates up to 96kS/s. The data format is IEC60958, otherwise known as
SPDIF. RCA connectors are the type commonly found on consumer equipment.
Use with 75 ohm co-axial cables designed for digital audio or RF use. Some
types of audio cable are not suitable and may cause crackling noises or other
malfunctions.
Toslink and ST Optical Inputs
The Toslink and ST inputs are used for optically transmitted digital signals with
sample rates up to 48kS/s. In practice, the interfaces are tested up to 96kS/s
but dCS cannot guarantee this with non-dCS source equipment. The data format
is IEC60958, otherwise known as SPDIF.
Use the Toslink input with Toslink fibre optic cables designed for digital audio
use. Use the ST input with ST style fibre optic cables. Pull off the plastic cover
before use.

REC Digital Output
The REC output buffers and loops through the selected single wire input data
with sample rates up to 96kS/s. The data format is the same as the selected
input (i.e. AES3 or IEC60958), the electrical format is SPDIF. It may be
connected to a digital recorder or another DAC. Use with 75 ohm co-axial
cables designed for digital audio or RF use.
IMPORTANT!
This output is intended for use with Single AES, RCA, BNC, Toslink or ST
inputs ONLY. If the selected input is in any other format, the REC output
will carry either the left channel data or full scale noise.
IMPORTANT!
If the selected input is SPDIF and the Copy Prohibit flag in the source data is
set, the REC output will be the same and you will not be able to record the
data.
1394 Interface
Units fitted with an IEEE 1394 multi-channel interface feature two 6-way 1394
connectors. The active source is selected by the Input button, see page 36.
In this release, the unit accepts DSD data at 2.822MS/s from either 1394
connector. For correct operation, the source must generate a 44.1kHz
wordclock (or be locked to a master clock running at 44.1kHz) and this must be
connected to Delius’ Wordclock In connector. We recommend using the 1.8
metre long, 6-way IEEE 1394 cable assembly and the BNC cable assembly
provided. See the “IEEE 1394 Overview” section on page 50 for more
information.
Wordclock Digital Input / Output
The Wordclock Input accepts a Wordclock at sample rates up to 96kS/s. It
allows Delius and your source equipment (e.g. CD or DVD player) to be
synchronised to a master clock. This arrangement helps reduce jitter, which can
degrade the audio output. See the MS menu page on page 23 for details.
The Wordclock Output is intended to synchronise other equipment to Delius. In
Master mode, the unit outputs a 44.1kHz master clock for other equipment to
lock to. In Slave or Sync modes, this output is disabled. See the MS menu page
starting on page 23 for more details.
There is no data on the Wordclock interface. Use with 75 ohm co-axial cables
designed for digital audio or RF use.
SUC
The Software Upgrade Connector is intended to be used by dCS service agents
to load new software into Delius.
IMPORTANT!
Do not connect any other equipment to the SUC connector as this may
damage both Delius and the equipment so connected. Do not operate Delius
with a PC connected. Failure to observe this warning will void the unit’s
warranty, and may cause unpleasant effects in your system.

Clocking
The sample clock quality significantly determines the output performance of the
converter. The highest quality clocks that are available are crystals, so we use
these. Delius uses two on-board voltage controlled crystal oscillators (VCXO’s)
as clock sources - one for the 44.1kS/s related outputs and one for the 48kS/s
related outputs.
Only one VCXO is active at a time. In slave mode, the active VCXO is
synchronised to the clock signal extracted from the input by a phase locked loop
(PLL). This PLL is of a special narrow bandwidth type, that provides a
significant degree of "clock cleaning”. The PLL is also very robust, and will lock
to very poor signals if necessary. Data is decoded using a much wider band
(faster) PLL, so AES3 type low frequency jitter on the input clock can be
handled, and will be cleaned.

GENERAL TECHNICAL INFORMATION
IEEE 1394 Overview
The IEEE 1394 interface is a high speed multi-channel system. It has the
capacity to carry over 50 channels of DSD (Direct Stream Digital) or over 30
channels of 24 bit / 192kS/s audio data through a single cable.
From October 2001 onwards, a pair of 6-way electrical IEEE 1394 interfaces
running at 200Mbit/s are available on the following dCS products:
•
•
•
•
•
dCS Elgar Plus DAC, standard fit with software version 4.10 or later.
dCS Delius DAC, optional fit with software version 2.10 or later.
dCS Purcell Upsampler, optional fit with software version 2.11 or later.
dCS Verdi SACD/CD Transport, standard fit.
dCS Verdi La Scala Upsampling SACD/CD Transport, standard fit.
In the current implementation, Purcell can upsample standard digital formats
(such as CD at 44.1kS/s 16 bits) to DSD at 2.822MS/s and output a stereo pair
of DSD data onto its 1394 interface. Verdi can read DSD data from an SACD
and output a stereo pair of DSD data onto its 1394 interface. The data is
encrypted to conform to the conditions of the DSD licensing arrangements.
Either Elgar Plus or Delius will accept DSD data from the 1394 interface and
convert it to high quality analogue.
The hardware interface is very flexible and software configurable. We will add
other features and data formats at a later date, adopting industry standard
formats as they stabilise.
Synchronising IEEE 1394 interfaces
The IEEE 1394 system is great for carrying large amounts or digital audio data
– but is inherently very jittery. To ensure low-jitter conversion to analogue, each
unit linked by the 1394 system must be synchronised to the others by another
connection.
•
•
•
A DAC in slave mode should be sync’ed to Verdi by connecting Verdi’s
WClk Out to the DAC’s WClk In.
A DAC in master mode should sync Verdi by connecting the DAC’s WClk
Out to Verdi’s WClk In.
An Upsampler should be slaved to Verdi, usually by the selected PCM input
(AES or RCA).
Automatic Input Selection
From October 2002 onwards, the software on the following products has been
enhanced to automatically select the interface carrying data from Verdi:
•
•
•
•
dCS Elgar Plus DAC, standard fit with software version 4.20 or later.
dCS Delius DAC, optional fit with software version 2.20 or later.
dCS Verdi SACD/CD Transport, standard fit with software version 1.20 or
later.
dCS Verdi La Scala Upsampling SACD/CD Transport, standard fit, with the
Easy Play menu set to Verdi.
The system relies on a 1394 link between Verdi and the DAC. The DAC will
automatically change inputs whenever Verdi changes layer or starts playing.

If the Verdi starts playing an SACD, the DAC selects that 1394 channel.
If the Verdi starts playing a CD and:
•
•
•
there is a second source on the 1394 bus (such as a Purcell), the DAC will
select the other source.
there are more than two other sources on the 1394 bus (such as a Purcell
or another Verdi), the DAC will select one of the other sources. You may
have to manually select the source you want.
Verdi is the only source on the 1394 bus, the DAC will scan the PCM inputs
and select the first active one it finds. The priority order is: AES1 (and Dual
AES) first, AES2, RCA1, RCA2, TOS, ST, BNC. If the active input is not
derived from Verdi, you may have to manually select the source you want.
If none of the PCM inputs are active, the DAC will remain selected to the
original 1394 channel.
This arrangement works best with only two inputs connected to the DAC –
Verdi’s 1394 feed for SACD’s and either a PCM feed from Verdi or an
upsampled feed from Verdi. The DAC can be in master or slave mode – we
recommend master mode.
If you are using a Purcell in Dual AES mode (rather than DSD mode), you
should set the DAC’s Dual AES menu page to either Lock or Auto.
The DAC has enough information about the system set-up to report connection
and setting errors. These are:

Mains Voltage Setting
Before connecting the power cable to your Delius for the first time, please check
that it has been set to the correct operating voltage for your local mains supply.
50Hz or 60Hz operation is not important – the unit can use either. The unit's
present voltage setting is shown on the label beneath the mains inlet on the rear
panel. If this does not match your local supply voltage, DO NOT attempt to use
the unit. Contact your dealer to arrange to have the unit reset. Using the Delius
with the wrong mains setting for your local supply may result in serious damage
to the unit and will invalidate the warranty. DO NOT attempt to reset the unit
yourself.
IMPORTANT!
Please use a sensible power cable, such as the one supplied with the unit.
Some audiophile power cables presently available are excessively heavy,
their weight can damage the power inlet connector. Such damage is not
covered by the warranty.
Positioning the Unit
Place Delius on a firm, vibration free base so as to allow convenient connection
to your digital source. We suggest that you avoid siting Delius either directly
above or below preamplifiers or tuners, if either of these will be used in your
system at the same time as Delius.

MAINTENANCE AND SUPPORT
Service & Maintenance
dCS audio products are designed not to need regular maintenance, and contain
no user serviceable parts apart from the mains fuse.
Obtaining Service
If you experience problems with your Delius, you should check the
“Troubleshooting” section on page 64. You may be able to resolve the situation
yourself (for example, by changing a menu setting).
If this does not resolve the problem, contact your authorised dCS dealer for
advice, quoting the model, the full serial number (see Serial on page 32), the
software version number (see Issue on page 32) and giving a detailed
description of the fault. If further action is necessary, your dealer will advise you
fully.
Mains Fuse
There is a mains fuse below the power inlet, accessible from the outside of the
unit. If the fuse blows, it may be changed by the user. The current consumption
of the unit is very low, so it only blows if power surges occur, or there is a fault
in the unit. Usually, power surges cause no other damage, but if the fuse blows
repeatedly on replacement, some other damage will have been done and the
unit must be returned to dCS for repair.
Fuse Type: 20 x 5mm 0.5 amp T HRC fuse
IMPORTANT!
If the fuse should fail, it is essential that it be replaced with one of the same
type and rating. Failure to do so could result in damage to the unit, risk of
fire or electric shock and will invalidate the guarantee.
Replacing a Blown Fuse
x
Referring to Figure 11, remove the power cable, use a small flat bladed
screwdriver to pry up the tab on the fuse carrier (A) and pull it out. Push the
blown fuse out of the clip in the carrier (B) and dispose of it. Fit a new fuse in
the clip (C) and push the carrier back into the unit so that it clicks home. Spare
fuses are provided with the unit.

Updating your Delius
dCS products make extensive use of software configurable chips – FPGAs and
DSPs. This gives us the ability to update our products to add extra features,
update digital interface standards or make performance improvements by
loading new software. Occasionally, a hardware update may be necessary also
to increase the “capacity” of the electronics, add extra connectors or extra front
panel controls.
Software Updates
x
Please note that not all software updates make an earth-shattering change. You
should have a clear idea of what you expect to gain before updating to the latest
issue.
If the software loaded in your unit is (for example) version 3.45:
•
•
•
A change to version 3.46 indicates a minor update for internal dCS use – to
make testing easier, or more thorough, or to cater for some minor hardware
change. Do not update your unit.
A change to version 3.50 is a more serious update, offering extra
functionality. If you want to use the extra features, update your unit. The
manual will be updated for this (check the web-site).
A change to version 4.00 is a major update. It will require updated hardware
and the manual will be updated
If you have older hardware, some of the features added by new software may
not be available due to (for example) a missing connector. For recent
hardware, this is mentioned in the “Upgrader’s notes” in this manual. If you
need the missing feature, contact your dealer or dCS to arrange a hardware
update.
•
If the software currently loaded includes a CD Update page, you can
update the software yourself. Contact dCS for a CD and follow the
instructions in the CD Update section on page 33, or the instructions
supplied with the CD. The update program will check your hardware
configuration and install the latest software compatible with it.
•
•
If you do not have the CD Update feature loaded or have difficulty with it, a
dCS distributor can download files from a PC into any unit fitted with a SUC
connector. Contact your dealer for details.
For older units without a SUC connector, your distributor can install new
firmware in your unit. Firmware updates are low-cost from dCS. Contact your
dealer for details.
Hardware Updates
x
You may wish to have your hardware updated from time to time to take
advantage of new features in the latest software. dCS offer this service - we will
retest, reset any adjustable items to current shipping standards, and install any
modifications or updates that have occurred since your unit was first shipped.
The price will depend on the hardware changes necessary – please contact
your dealer or dCS for details and pricing. In order to ensure speedy turn
around, please contact us prior to returning the unit to get a Service Return
number.

TROUBLESHOOTING
Fault Indication
Delius detects the following fault conditions:
Power interruption
If the AC supply is momentarily interrupted or is more than 20% below it’s rated
voltage, the unit displays PowerDn and mutes the audio outputs to protect your
loudspeakers from damage. This may be caused by loose AC power wiring,
local power-line overloads or heavy-duty appliances like air conditioners. If this
message appears frequently (other than when switching the unit off), please
consult your dealer.
Power up test errors
If Delius detects a fault during its power up test routine, it will remain muted and
display one of these messages:
•
•
•
•
DSPs Not Loaded (#01)
FPGAs Not loaded (#02)
Bad Checksum. Press any key to attempt recovery (#03)
DSP-Err1 (#04)
This can be caused by power line transients occurring during system
configuration. For Bad Checksum, press any button to try to clear the fault.
Otherwise, try switching off, waiting 20 seconds, then switching on again. If the
fault persists, please consult your dealer.
Non-Audio disk
Playing a Non-Audio CD (e.g. CD-I, CD-R, Photo CD, etc.) causes Delius to
remain muted and display Nonaudio.
If you are SURE the disk is playable audio, Delius can be set to ignore this flag.
The Non-Audio flag may have been incorrectly set on the CD. See NAud on
page 29.
IMPORTANT!
The Non-Audio Muting feature protects your ears and equipment from
damage. Think carefully before turning it off.
The unit is overheating
If the internal temperature sensor detects a high running temperature (over
70°C or 158°F), the unit displays Too Hot!.
If this occurs, there is insufficient ventilation, causing the unit to overheat.
Switch off and allow the unit to cool for 10 minutes. Check that air flow around
the unit is not restricted and that it is not located above a power amplifier or
other source of heat. Continuous operation at these high temperatures may
result in permanent damage and will invalidate the warranty. See “Operating
Conditions” on page 49.

Troubleshooting Guide
If you experience difficulties when using Delius, the following suggestions may
help resolve the problem.
The unit fails to power up
• Ensure there is power available on the mains cable. Connect the power
cable, wait 10 seconds then press the Power/Standby button.
• Check the rated supply voltage shown on the rear of the unit matches the
local supply voltage.
• Check that the fuse has not blown - if so, correct any obvious cause then
replace the fuse as described on page 60.
The unit fails to lock to a digital audio source or displays “No Input”
• Ensure the correct input is selected (see page 36).
• Check that the digital audio cable is of the correct type, correctly connected
and not damaged. Try another cable. Damaged cables are a VERY
common cause of malfunctions!
• Check that the source is switched on.
• Some CD players do not generate a digital output unless the disc is playing
- set the player in “play” mode and check that the unit locks.
• Occasionally, we find a CD player whose sample rate is outside the
standard +/-300ppm tolerance specified for CD players. If Delius locks to
another source but not to your CD player, the player may need servicing.
• If you are using Master mode or a Master Clock, try slaving to the audio
input. If the unit locks, check the Wordclock connections.
The unit locks but the audio output is low or absent
• Check that the MUTE indicator is off. If not, press the Mute button.
• Check that the audio output cables are correctly connected, the equipment
following Delius is switched on and correctly set up.
• Ensure the Volume and Balance controls are correctly set (see Rotary
Control on page 38 and Bal Mode on page 28)
•
Ensure the source is sending audio data (see NAud on page 29).
•
Ensure the Output Level is correctly set - turn the Volume control down by
10dB before changing this setting.
The output is monophonic
• The source is Dual AES but Delius is set to Single AES (AES1 or AES2
indicator lit) – see page 25.
•
If both AES1 & AES2 indicators are flashing, the unit is set to Dual AES –
•
Lock but one AES cable is either disconnected or faulty (see page 25)
The source disk / tape may actually be monophonic.

The unit fails to respond to the controls
• Check that the STBY indicator is not lit - if so press the Power/Standby
button to return to normal operation. Alternatively, switch off, wait 10
seconds and switch on – Standby mode will be cancelled.
• While locking to a source or changing some settings (e.g. Filter), the
microcontroller inside Delius is busy and will not respond to new commands
for a few seconds.
•
•
If the Mute fade-out rate is set to Mute-Slw, the unit may be unresponsive
for a few seconds while slow muting is in progress (see page 24)
Short mains supply drop-outs may cause the microcontroller to lock up.
Switch off the unit, wait 10 seconds then switch on again. If this does not
clear the fault, please contact your dealer.
The Main Display turns on briefly when a control is operated, then turns off
•
This happens when the Display Brightness is set to Bright 0. Change to
any other brightness setting to stop the display blanking out (see page 26).
The Left and Right channels are swapped
• Check that the audio output cables are not reversed.
•
Open the menu and page through until the Swap page is displayed. If it is
•
set to Swap-On, change it to Swap-Off.
Check that the channels are not swapped elsewhere in the system.
•
If you are using Dual AES mode, ensure that AES 1 input is connected to
the output on the source equipment carrying the Left channel data (probably
labelled AES1 or AES A) and the AES 2 input is connected to the output on
the source equipment carrying the Right channel data (probably labelled
AES2 or AES B). See the manual for the source equipment for information,
and also page 25.
One audio output channel is low or absent
• Check that the Balance control is correctly set (see Rotary Control on
page 38).
• Check that the audio output cables are connected correctly and are not
damaged.
• Check that the balance is not offset elsewhere in the system.
The sound has a peculiar tonal balance
•
•
Set De-Emphasis to Auto – see page 27.
If this fails to correct the problem, the De-Emphasis flags in the data stream
may be incorrectly set (this is rare but it does happen). To find the correct
De-Emphasis characteristic, change the De-Emphasis setting to 50/15µs,
CCITT or Off in turn until the correct setting is found. When you change to a
different disk or tape, we recommend setting De-Emph to Auto again.

Crackles or pops occur while playing music
•
•
•
•
•
The source may have a high level of jitter. Try setting the PLL parameter to
PLL:Wide. See page 29.
The digital audio cable connecting Delius to the source may be damaged,
intermittent or of the wrong type. Some expensive cables are not correctly
designed for digital audio use. Try another cable.
The CD may be dirty - clean it very carefully using a radial motion.
The disk / tape may be damaged or contain corrupted data.
The audio output level may be enough to overload a preamplifier or power
amplifier.
Erratic operation when locked to 96 or 88.2kS/s on Toslink or ST inputs
• Check your optical connections are clean and properly installed.
• The Toslink and ST receiver devices are industry standard types which are
not guaranteed to operate correctly at 96 or 88.2kS/s. Connect to a different
input instead.
The unit will not decode Dual AES
•
•
Dual AES mode may be disabled. Open the menu and set the Dual AES
page to On (see page 25). Connect a valid 88.2, 96, 176.4 or 192kS/s Dual
AES source to both AES 1 and AES 2 inputs. Press the Input selector
button repeatedly until both AES1 and AES2 indicators are lit.
Your source equipment may have two AES outputs but might not be
capable of Dual AES operation. Check the manual for the source
equipment.
The unit drops out of Dual AES mode into AES1 or AES2
• Dual AES mode is only available if AES data streams are available on both
AES 1 and AES 2 inputs. If either of these are interrupted or become
corrupted while in Dual AES mode, the unit may default to single AES mode
and select the valid input. Check for faulty wiring to the input which has
•
been deselected. Once both data streams are stable again, Dual AES mode
may be selected using the Input button or the Remote Control. See page
25.
If you are driving Delius direct from an Upsampler always set to output Dual
AES, you may find that changing inputs on the Upsampler causes Delius to
fall out of Dual AES mode. To prevent this, Delius may be locked in Dual
AES mode. Open the menu and page through until you reach the Dual AES
page. Change the setting to Lock. Select AES 1 or AES 2 input on Delius
and it will enter Dual AES mode automatically (see page 25).
A digital recorder fails to record from the REC Output
• If Delius is selected to an SPDIF input (RCA, BNC, ST or TOSLINK) and
the source data (CD for example) is copy protected, your recorder will be
prevented from recording the data. This prevents copyright infringement.
Note that AES data streams have no Copy Prohibit flag.
• In some DAT machines, the digital input is connected directly to a digital
output without buffering. This arrangement does not comply with the
IEC60958 standard. Connecting another device to this may overload Delius’
REC output and corrupt the digital data.
• The REC output is usable with single AES, RCA, BNC, Toslink or ST
inputs ONLY.

The Remote Control fails to control the unit
• The Remote Control is normally shipped with the batteries packed
separately for safety reasons. If you are using the Remote Control for the
first time, you must fit the batteries first – see page 61.
• If the Remote Control has not been used for a long time or has gradually
lost range, the batteries should be replaced - see page 61.
• If you have just replaced the batteries but the unit still does not work, check
that the batteries are fitted the right way around - see page 61. If two or
more batteries were fitted the wrong around, the Remote Control may be
permanently damaged. If this occurs, contact your dealer for advice.
• For correct operation, there must be a clear line of sight between the
infrared transmitter at the end of the Remote Control and the infrared
receiver in Delius, located on the left hand side of the display. If the line of
sight is blocked (for example by a coffee table) the Remote Control may
operate erratically or not at all.
• While the unit is displaying Locking or Wait ..., the system timing is
fluctuating and this may temporarily disrupt the operation of the Remote
Control. Once the unit locks, normal operation will be resumed.
While playing a DVD, a burst of noise is heard, Delius mutes and changes sample rate
• We have found that some DVDs have been compiled with tracks recorded
at different sample rates (e.g. 96kS/s & 48kS/s). There is no warning of this
sudden change in sample rate (this could be done by using the Non-Audio
flag or by changing the sample rate code in the data stream), so the DAC
tries to decode corrupted data momentarily before registering loss of sync,
muting and re-locking. The root cause of the problem is a lack of a formal
interface standard covering sample rates above 48kS/s. When a new
standard is agreed, Delius’ software can be updated to comply with it. This
is unlikely to improve the situation with existing disks. Meanwhile, we
suggest you reduce the volume at the end of the track where a change
occurs and increase it when Delius displays a new sample rate.
CD Update is interrupted or fails
• If a software update from a dCS CD is interrupted, the original software
may be recovered by switching Delius off and on, then waiting a few
•
•
minutes. See CD Update on page 33.
If you are using an Upsampler or other device, ensure it is set to bit-for-bit
(Clone) mode.
If your CD player upsamples to 48kS/s or 88.2kS/s or adds dither (a few
types do this), the update program will reject the data. Use or borrow an
“ordinary” CD player.
CD Update is interrupted and fails to recover
• It is just possible (but very unlikely) that the recovery will fail if the recovery
code was being over-written when the interruption occurred. If you are very
unlucky and this happens, ask your dealer for help. New software must be
loaded from an EPROM.

Troubleshooting the IEEE 1394 Interface
This section covers difficulties that may be encountered using a dCS Verdi
SACD Transport (v1.20 or later), a dCS Verdi La Scala Upsampling SACD
Transport or a dCS Purcell Upsampler to drive a dCS Elgar Plus DAC (v4.20 or
later) or Delius DAC (v2.20 or later) with DSD data over an IEEE 1394 interface.
Upsampler or Transport displays “Inactive”
• This can happen momentarily during locking. If it does not change to
Active, open the Transport or Upsampler’s menu and ensure the Transmit
page is set to Active.
The Unit keeps displaying “No Comms”
• This will appear briefly while the 1394 system is checking for connections.
• If the No Comms message does not clear, ensure that all units in the 1394
chain are switched on and securely connected by 1394 cables.
The Unit keeps displaying “Search..”
• This will appear briefly after the 1394 system has established
communications.
• If the Search message does not clear, ensure that you have not connected
both 1394 connectors from one unit to both 1394 connectors on another unit
or set up a loop. This prevents the 1394 bus settling.
• Check that the 1394 cables are correctly fitted.
The DAC displays “Verdi Wordclock Missing”
• With the DAC in slave mode, check there is an undamaged BNC cable
connecting Verdi’s WClk Out to the DAC’s WClk In.
• Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
The DAC displays “Missing Wordclock between Clk Out & Verdi Clk In”
• With the DAC in master mode, check there is an undamaged BNC cable
connecting the DAC’s WClk Out to Verdi’s WClk In.
• Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
The DAC displays “Please check source slaved to DAC Wordclock Out”
• With the DAC in master mode, check there is an undamaged BNC cable
connecting the DAC’s WClk Out to the source’s WClk In.
• Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.
The DAC displays “Wrong Wordclock @ Verdi Clk In”
• Verdi / La Scala has detected a clock frequency other than 44.1kHz on it’s
WClk In connector. Ensure the clock source is set to 44.1kHz.
• With the DAC in master mode, check there is an undamaged BNC cable
connecting Verdi / La Scala’s WClk Out to the DAC’s WClk In.
• Ensure the cable is D.C. coupled. A.C. coupled cables are not suitable for
use with Wordclock or SDIF.

The DAC remains muted
•
If the DAC is displaying the Volume setting, change the Disp menu page
•
setting to Disp:Fs and check for error messages.
If all else is in order, switch off the Transport, the Upsampler and the DAC
then switch them on again. If this situation keeps recurring, please consult
your dealer.
The DAC takes a long time to unmute
• The 1394 interface can take around 30 seconds to settle and unmute.
•
•
Try setting the DAC to 1394 mode before setting the Upsampler to DSD
mode.
If your system is in standby mode or switched off, try turning the DAC on
before the Upsampler or Transport.
If this information does not resolve the problem, please contact your dealer for
advice.

INDEXES AND SOFTWARE VERSION NUMBERS
Software History
This manual is for Delius software version 2.3x.
Version 2.3x differs from 2.2x versions as follows:
In PCM mode, Delius can now lock to an external word clock that is at an exact
multiple of the sample rate. For example:
• with a data rate of 96kS/s, the word clock may be at 32, 48 or 96kHz
(previously 96kHz only).
• with Dual AES data at 176.4kS/s, the word clock may be at 44.1 or 88.2kHz
(previously 88.2kHz only).
• with Dual AES data at 192kS/s, the word clock may be at 32, 48 or 96kHz
(previously 96kHz only).
Note that DSD mode still requires a 44.1kHz word clock only.
Version 2.2x differs from 2.1x versions as follows:
• (Units with 1394 option only) Delius responds to status messages sent over
the 1394 interface from a Verdi (v1.2x) to allow automatic switching
between SACD and CD modes. This also allows Delius to report any cabling
faults.
•
1394 Src menu deleted – 1394 sources are selected with the Input button
or automatically selected by a Verdi.
•
Clock menu deleted. In Master mode, Delius outputs a Wordclock at
44.1kHz only. Wordclock Out is disabled in Slave or Sync modes.
•
Part No. menu deleted.
•
After a Factory reset, the inputs are set up to match the other dCS units in
the system.
1394 operation generally improved, system messages changed.
•
Version 2.1x differs from 2.0x versions as follows:
• menu order rearranged.
• improved IEEE 1394 interface behaviour.
•
Reset Sync menu added.
Version 2.0x differs from 1.1x versions in supporting DSD at 2.822MS/s over
the optional IEEE 1394 interface.
(Upgrader’s note: the 1394 interface hardware may be retrofitted to any unit.)
Version 1.13 differs from version 1.11 in supporting synchronisation to the
Wordclock Input.
(Upgrader’s note: on units manufactured before February 2001, the Wordclock
Input was labelled OPTION or was blanked off.)
Version 1.11 differs from version 1.0x as follows:
•
•
•
•
in supporting Master Mode clock operation (it can give out a clock for CD
players, for example, to lock to),
in supporting updates of the software by CD,
and in offering more filters (6 instead of 4 at 176.4 kS/s and 192 kS/s)
in allowing partial resets.
