Instruction Manual
Rev 1.2
Congratulations on purchasing a Creek EVOLUTION 50CD. Please read this manual thoroughly as it will explain in detail the features and operation of your EVOLUTION 50CD and
help to ensure a trouble free installation. Unpack the player carefully, as it is recommended
that you save the carton and packing material for future use, should you need to move home
or return it for service etc.
The EVOLUTION 50CD is designed to operate on either 220-240 Volts - 50 Hz AC, or 110120 Volts - 60 Hz AC. The voltage selector switch is located on the bottom of the case; to
select a different voltage range, use a small flat-blade screwdriver to push the switch from
one position to the other. A mains fuse is fitted to a sliding tray inside the IEC socket. There
is a spare one also fitted inside and they are designed to work in both voltage ranges. If the
mains fuse fails and the spare fails also when fitted, it usually indicates a serious internal
fault and the product should be returned to the dealer or a specialised service company for
inspection and or repair. Do not attempt to effect repairs yourself.
The product has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in residential installations.
Install the equipment in a location which is relatively free of moisture and dust, and is well
ventilated. The equipment may not be able to perform at its best in an extremely cold or hot
environment. Do not attempt to use below 5 C / 41 F or above 35 C / 95 F.
Always handle compact discs with clean hands. Avoid using scratched discs. Do not attempt to clean the CD
player or discs with chemical solvents, as this may cause irreparable damage. Use a clean, dry cloth, or specially designed cleaning materials for discs. If the CD player malfunctions, do not open the unit and attempt
to repair it yourself. This is a highly technical product and requires specialist service – please return it to your
Use two batteries (2 x AA) of the same type in the remote control handset. Do not use odd
or different type cells as it may affect the performance.
Keep this manual in a safe place for future reference.

The EVOLUTION 50CD is not just a CD Player; it is primarily a Digital to Analogue Converter and Pre-amplifier, fitted with a Slot Drive CD transport as one of its digital sources. The
DAC has 2x SPDIF and 2x TOSLINK digital inputs capable of reading digital signals up to
24 bit 192 kHz high-resolution. The USB input is capable of playing 24 bit 96 kHz files from
either a PC or MAC computer, without additional software drivers needing to be installed.
Connect your EVOLUTION 50CD to a suitable audio amplifier. Creek Audio recommends
the EVOLUTION 50A or EVOLUTION 100A integrated amplifier as a perfect cosmetic and
performance match, but virtually any stereo amplifier with a line-level input and volume control should be OK. If you enable the EVOLUTION 50A’s volume control, it is possible to just
use it with a Power Amplifier.
Connect the mains supply using the 3-core mains cord supplied. Push the 3 pin IEC plug
into the socket on the rear panel of the EVOLUTION 50CD and plug the other end into a
suitable wall socket. Do not overload the socket with too many connectors. Ask your dealer
for advice if in doubt.
Use a pair of good-quality stereo interconnects to join the analogue output of the DAC/CD
Player to the input of your amplifier. There are both un-balanced and balanced outputs available. Although it is possible to use both outputs simultaneously we do not recommend it,
as it can reduce the performance. NEVER use Balanced-to-Unbalanced cables such as an
XLR to RCA cable, as these will give poor performance and could damage the EVOLUTION
Note: Balanced outputs can be connected directly to the EVOLUTION 50A amplifier and if the distance between them is greater than 5 metres, this may provide a better quality of sound. Balanced audio, using XLRs is
a professional standard and designed to eliminate unwanted noise or hum over long cable lengths. For shorter
cable runs it may not improve the sound of your system, because of the additional circuitry required, so please
experiment to see what works best. Just as with un-balanced interconnects, cable quality can affect the sound
quality. Ask your dealer for advice if you are not sure.
Output level:
The factory setting fixes the output level at ‘Line Level (0dB max)’, by default. If you wish to
change this to become variable, Pre-Amplifier Mode must be enabled through the start-up
Menu. To enable ‘Preamplfier Mode’ start with the EVOLUTION 50CD switched off. Press
the MENU button and hold it down simultaneously while pressing the power button on, to
reveal a hidden Menu.
The Setup Menu will display the following: ‘Analogue Output’ and ‘Factory Defaults’.
To enable the EVOLUTION 50CD to have a volume controlled output - Select Analogue
Output by pressing the Play/Pause button. Press either the Track Back/Forward button until

Pre-amplifier Mode is highlighted. Press the MENU button to confirm. The window will briefly display the CREEK logo and the unit will then be in normal working mode.
You will see there is now an indication of the volume setting in the bottom right hand corner
of the display. Volume adjustment can be made using the remote handset blue + or – button, after the CD or DAC button at the top has been pressed. When using the volume control the display will switch to showing the full level setting for a short time and then return to
show the input with a small level display only.
To return to a fixed level output follow the same path as above, but select LINE LEVEL (0dB)
and then MENU. Alternatively, select Factory defaults, the press ‘Reset to Defaults’. Press
Play/Pause or Menu to return to normal operation.

Press Play to start playing the disc. If available, CD text will scroll across the top of the display, indicating among other things possible, the artist, album and track name.
Press the Stop button to end play.
To load a disc, simply post one through the slot aperture on the left hand side of the front
panel, with the label facing upwards, being careful not to put finger prints or dirt etc. on the
playing surface. The mechanism will sense the proximity of the disc after it is half way in. It
will then automatically draw the disc inside completely and read its Table of Contents (TOC),
which will be displayed. It will then be in the Stop position.
To remove a disc, press the Eject button to force the disc out of the slot drive. Pressing Eject
while the disc is playing will not harm the disc.

Press DAC button first. The DAC will operate like a digital pre-amp, allowing you to select a
different input for various digital sources. Some digital devices output their signal optically,
so use a good quality TOSLINK cable to pass the signal to the DAC. Some products use
only co-axial connections. Use a dedicated ‘digital interconnect’ for the best results. Ask
your dealer for advice.
The EVOLUTION 50CD can supports digital input signals from 16 to 24 Bit word lengths and
sample rates from 32 kHz to 192 kHz. The incoming signal will be checked and the sample
rate will automatically be displayed.
All digital signals will be output via the co-ax or optical connectors, to allow another device
to receive the same signal.
USB input, allows the DAC to behave like a sound card. Your computer will recognise the
USB DAC and should have no problem linking to it automatically. Once the link is established audio data can be transferred and converted at the highest quality. The remote control will allow limited control of the incoming signal, such as play, pause, stop etc. However,
if a media player such as iTunes is used, it is much more convenient to control files using
the (remote) App to view and control your library via a tablet computer, smart phone or other
remote device. The USB input is totally galvanically isolated to prevent any computer generated electrical noise from interfering with its performance.
Toggling the FILTER button on the remote handset selects five available digital filter options.
These are used by the DAC to reconstruct the analogue waveform from the digital signal
provided by the source. The five filters offer differing compromises between performance
and suppression of ultrasonic noise. The best option will be system dependant so try experimenting to see which option you prefer. The differences are very subtle so it may take some
time to find your favourite! None of the filters significantly affect the frequency response in
the critical 20Hz – 20kHz audible range so don’t be worried about having the “wrong” selection; there is no right or wrong option.
