Installation
Prepare your installation site by following the steps
below: Consult page “Rear Panel” on page 4
for rear panel diagram indicating location of key
connections.
1. For non North American models that are
delivered with a fuse attached to the AC cord,
install the fuse before plugging the unit into
mains power.
2. Ensure your electrical circuit has a good ground
connection with all audio equipment connected
to the same ground node to avoid noise or hum
due to a ground loop.
3. Prepare attached equipment such as display or
projector, audio amplifiers, speakers, network
switch and associated cables.
4. Network should be running a DHCP server to
enable the SP4 to obtain an IP address.
Ventilation
The SP4 is a cool-running line level component. It
generates far less heat than amplifiers and many
other components. It can be safely placed inside
furniture or an equipment rack. However, it should
not be tightly enclosed. Some airflow is desired.
Note that the rear panel fan needs to be able to
circulate air especially when the SP4 is under heavy
load.
Connecting to A/C Power
If necessary, install the included fuse into the fuse
socket. Plug the IEC-320 C14 end of the power
cord into the SP4, then plug the other end into an
approved and grounded A/C receptacle.
Connecting to Network
Using at CAT5e or better cable, connect the SP4 to
your local area network. See “Get Network Access”
on page 7 to identify IP address.
Connect IR Interface (Optional)
Should you choose to use an IR interface, you will
need to connect an IR receiver to the IR Input of the
SP4.
SP4 Immersive Surround Processor
Connect Source Components
Legacy digital sources can be connected to the
digital inputs 1-6. Stereo or surround analog sources
can be connected to the Analog Inputs section.
Analog input configuration is defined at “4. Audio In”
on page 12. HDMI sources can be connected as
well. Note that though all inputs support HDCP2.2,
inputs 1-4 only support HDMI 1.4 speeds by default.
Inupts 5-7 support HDMI 2.0 speeds.
Connect to Display
Connect your displays using HDMI output. Note
that outputs are parallel (same content) but HDMI
OUT 1 supports up to HDCP 1.4 while HDMI OUT 2
supports HDCP 2.2. Should no picture appear on
HDMI OUT 1, troubleshoot EDID conflicts.
Connect Audio Outputs
If you choose to connect your outputs at this step,
take note of which output number is routed to each
channel so that you can map them appropriately
in a later step. Otherwise, when you setup the
theater using the web UI, the default outputs will be
noted for you. At that point, you can connect your
amplifiers based on the default output channel
mapping.
First Run
Upon first run, you must configure the SP4
according to your specifications using the web
based user interface. There is no on-screen display
or provision to configure the unit using the front
panel.
Power On

for instructions on resetting the network settings
to default DHCP mode.
5. Password Management
The SP4 has 3 levels of access. Remote Control
requires no password and no access to settings.
Installer has access to all settings. Expert is an
intermediate level that has access to settings
assigned by Installer. Those settings are defined
in the Access Management area at the bottom of
this page. The default passwords are:
Installer: installer
Expert User: expert
If you are a dealer or custom installer, you
are advised to change these passwords and
document them. Similarly, if you are a client and
SP4 Immersive Surround Processor
wish to lock other users out of settings, you may
wish to change default passwords as well.
If you have forgotten your passwords and have
locked yourself out of the SP4, you can reset
them back to default by following the procedure
“Default Passwords” on page 7.
6. Access Management
This area permits a user logged in as installer to
assign access to specific setup functions to the
Expert User. For example, if the SP4 is installed
at property with technical staff, the installer may
wish to permit the Expert User to make changes
to the inputs for the purposes of installing a new
source, but restrict their ability to make changes
to speaker EQ, apply firmware updates, etc. Any
setup menu marked “Y” in blue is accessible to a
user with the Expert User password.

Input Settings
The SP4 permits the installer to create access to
sources in a very intuitive way for the end user. The
installer is advised to title inputs thoughtfully and
without ambiguity. No longer must an end user
remember which physical input is attached to a
particular source component. Further, only inputs
specifically configured as ACTIVE will be available
from the remote control. Finally, multiple inputs
can be created from a single source component
for the purposes of loading separate settings. For
example, you may have an input titled ‘CD Music’
that accesses a Blu-Ray player attached to HDMI 7
that by default downmixes everything to stereo and
another input titled ‘Blu-Ray Movie’ that accesses
the same source component but upmixes all audio
to Dolby Surround.
1. Active
Any input with a blue Y is accessible from remote
controls. To disable access to an input, click the
Y and it will change to an N and gray out the
entire row thereby disabling access to this input.
You are advised to disable any input with no
source component attached.
2. Input
This is the name of the input that will appear
in remote control applications. By default, the
name is the same as the default audio input. You
12
may type in this box and change the name to
something more intuitive. Supports a maximum
of 10 characters.
3. Video In
For any given input, you can map separate video
and audio inputs except that when the audio
input is an HDMI input, the video input must be
the same HDMI input. None may also be chosen
when no video is desired.
4. Audio In
For any given input, you can map separate video
and audio inputs except that when the audio
input is an HDMI input, video must be the same
HDMI input. None may also be chosen when
no video is desired. Note that the analog input
matrix may be selected as a particular stereo
pair or as a 7.1 input.
5. Preferred Upmix
On a per input level, you may choose to engage
a particular upmixer, or leave the option set to
none. This setting overrides any preferred upmix
defined as part of a preset. So, if a preset is to
be used in conjunction with this input, and that
preset includes specifying an upmix, leave this
setting to None.
6. Trimmer
Each input may have the audio attenuated by a
SP4 Immersive Surround Processor
specific value in an effort to level match source
components and yield an expected volume level
in the room regardless of source selected. No
gain can be applied, only attenuation. The range
is -30dB to 0dB with 0.1dB precision. The + and buttons adjust the value by 0.5dB.
7. AV Delay
Each input may have a synchronization delay set
between video and audio. This range is 0-100ms
in 1ms increments.
8. Triggers
The SP4 can trigger connected devices on using
the 4 DC trigger output jacks on the back when
a specific input is selected. Most commonly,
this is used to power on the source component
connected to a specific input. To enable this
feature, the desired trigger must be set to Auto
Switching: Enabled on Input in the Settings
menu. See “Triggers” on page 26. To engage
a trigger based on input, click the gray N. It
will turn into a blue Y when the trigger will be
activated upon selection of that input.
Note that after making any changes, you
must press the SAVE button near the top
right of the screen or you will loose your
changes.

Building a Theater - Defining Channels
To assign analog outputs to particular channels,
you must build a theater. A theater may occupy as
few as 2 channels or as many as 16. There are over
70 options for theaters. Any channels left over may
be assigned to secondary multi-channel theaters, 2
channel A/V zones, audio only zones, mono zones
or if SphereAudio is installed, headphone zones. A
physical output can only be assigned to one theater
or zone.
To assign channel outputs, you must first build
a Theater or Zone. Theaters are multi-channel
systems. Zones are either 1 or 2 channel audio
or audio/video zones. Any theaters or zones
created appear to the right and are listed by
their names which you assign. By default, the
SP4 ships with a 2 channel theater configured.
To build your own, delete this theater and
create a new one. Click EDIT, then DELETE.
Click OK to confirm. You will be returned to the Main
Speakers page.
1. Create Theater
Click Create Theater to build your new theater.
Theater 1 will appear to the right of the Create
14
Theater button. Click Configure to proceed.
2. Select Speaker Layout
All possible loudspeaker layouts based on
available channel count are listed. A shorter
list “Recommended by Bryston” is listed by
default and contains most commonly used
options. Click All to see all possible options.
Definitions are titled by channel count in the
following order. Base Layer . LFE . Height Layer
. Top Layer. For example, 9.1.0.6 would feature
9 ear level speakers, 1 sub channel, 0 height
speakers (common only for Auro3D layouts),
and 6 ceiling speakers.
For each definition, you can use the
matrix to see how compatible that layout
is with each of the 3 codecs and which
possible speaker locations are occupied.
To reduce ambiguity, you can also click
VIEW to see the layout visualized in a room.

For each Theater, Sub-Theater, and zone, you
can save multiple profiles for different listening
preferences. Profiles can be recalled as part of
presets “Presets” on page 28. A profile includes
the following information: Speaker definition (multiway, levels, delays), bass management, manual EQ,
and Dirac filter design if applied.
Some clients have different EQ profiles based on the
type of content they listen to e.g. movies vs. music.

Ways per Speaker (LCR): For the front left, center,
and right speakers, you can define multi-way active
loudspeakers up to 3 ways per speaker.
Surround Layers: Optionally duplicate surround
channels to increase coverage in large rooms to
match seating row count.
•
Subwoofers: Though there is only 1 LFE channel,
you can specify the number of channels which will
drive discrete subwoofers. Unlike daisy chaining
subwoofers, each channel can have its own settings
and EQ.
•
Enabled Mode Layers: When using customized
Dolby Atmos up-firing loudspeakers in place of ceiling
mounted top layer speakers, choose whether these
speakers are mounted on top of the Front or Side
loudspeakers.

Click New to build a new profile from defaults.
3. Duplicate
Build a variation on a saved profile. This is
especially useful if you have a profile designed
with Dirac Live. Since you cannot edit Dirac
reference profiles directly, you can build a
duplicate and edit that duplicate.
4. Save
After any changes to a profile or creation of a
new one, you must SAVE your changes.

Test Tone Generator
The SP4 includes a highly configurable test tone
generator which can be used to help manually
calibrate channels.
1. Generator
Click this button to turn on the tone generator.
It will automatically start with Group 1. The
channels outputting sound will be highlighted in
green.
2. Setup
Unlike traditional generators, the SP4 will not
strictly play tones one channel at a time. Click
Setup to assign channels to groups. Each group
may contain one or more channels. For example,
if you have 2-way active loudspeakers, you
may wish to group the high frequency and low
frequency component of each into one group.
Choose the type of noise or tone created by the
generator.
•
Sine: Generates a sine wave at the frequency
specified.
•
Pink Noise: Generates full bandwidth pink noise
•
Pink Noise 400-4kHz: Generates pink noise band
limited to one decade. This is particularly useful
when setting relative levels between channels with
dramatically different useful bandwidths. Remember
SPL meters measure not only sound pressure but also
bandwidth.
4. Gain
The gain figure can be set so that the noise
generator operates at a level at or below that of
a normal source playing at 0dBFS. Default is 0.1
(-20dBFS).
5. Group
When the noise generator is active, use this
function to play the noise through different
groups defined in “2. Setup”.
6. RTA
3. Noise Selection
16
When a USB microphone (such as the optional
Theater Acoustic Diagnostic Kit) is connected
to the SP4, you can use the Real Time Analyzer
to visualize the response of loudspeaker
groups in the room. Note that the built in RTA
is not accurate enough to use for calibration,
but is useful for getting a good idea of the
SP4 Immersive Surround Processor
approximate response of the system. Maximum
level of the capture can be set by adjusting
Mic Ref Level. Graph vertical scale can be
changed from Logrithmic (default) to Linear.
7. Dirac
See “Dirac Live” on page 23 for use of optional
Dirac Live Calibration Tool.
8. Volume Reference
It is good practice when calibrating systems
to always work at a reference level such as
85dB C-weighted. Before activating the noise
generator, make sure the master volume is at
a low level. Set and recall a reference master
volume value. Click SET once you have dialed
the value you’d like to store. Click RECALL to
quickly return to that value.
Individual Channel Adjustments
Once your theater is defined, each channel can
be individually fine tuned. The theater can also be
renamed, and a child theater can be created which
enables stereo left, right, or mono audio to be
routed to existing channel assignments.
9. Channel Status
Each channel is enabled by default. If for some
reason this channel needs to be disabled, click
the ON button. It will turn to OFF and audio will
no longer be routed to that channel. Note that
audio will not be re-routed to other channels.
Channel status is set per Theater / Zone and is
not stored as part of a profile.
10.
EQ
Each channel can have up to 10 channels of
parametric EQ configured. See “Channel EQ” on
page 20 for detailed EQ options. EQ settings
are stored as part of profiles.
11.
Signal
12.
Channel Name
13.
Size / Filter
Indicates which signal is routed to this output.
Should you desire to remap signal routing, you
can do so with Output Mapping. See “Output
Mapping” on page 19 for details.
Customizable name to easily identify each
channel. By default, these are named for the
signal sent to each channel. You may decide
to change these to speaker model or another
unique identifier. Maximum allowable character
count is 25.
Identify each channel as either Large, Small,
or Large and Sub. When a channel is set to
Large, no bass is redirected from this channel
to the subwoofer. Use this setting when the
loudspeaker has sufficient bandwidth and
output capability to reproduce sufficient
bass. When a channel is set to Small, bass in
this channel is redirected to the subwoofers
according to the Frequency and Slope for that
channel. Large and Sub is a special case that
not only allows that channel to reproduce full
bandwidth audio, but also duplicates bass in
that channel to the subwoofer(s) according to
the Frequency and Slope for that channel.
Subwoofer channels have specific settings. By
definition, subwoofers have limited bandwidth
and some are more limited than others.
•
Low Pass LFE: When this is set to ON, the subwoofer
channel has a low pass filter applied according to
that channel’s Frequency and Slope. This is designed
to limit the channel’s ability to reproduce the upper
portion of the bass spectrum. This is usually done to
prevent the subwoofer from contributing midrange
distortion.
•
Subsonic SUB: When this is set to ON, a high pass
filter is applied to the channel which restricts the
subwoofer’s ability to reproduce very deep bass
according to the frequency and slope defined for
that channel. Many subwoofers, especially smaller
models do not have the amplifier power or driver
17
17

21
displacement required to accurately reproduce very
deep bass. By actively filtering very deep bass away
from the subwoofer, it is better able to reproduce
bass within it’s useful bandwidth.
* Items 14 and 15 pertain to Standard Bass
Management Mode in which the crossover point
and slope defined apply to both the high pass and
low pass sides of the filter equally. For Expert Bass
Management, see “Expert Bass Management” on
page 19.
14.
Frequency
When the channel is set to Small or Large and
Sub, the Frequency defines the point below
which bass in this channel is routed to the
subwoofer(s). Note that the frequency is the
-3dB point along the slope defined in the next
column and is not an absolute cutoff point.
15.
Slope
The rate at which bass is ‘crossed over’ into the
subwoofer when the channel is set to Small or
Large and Sub. LR 12dB and LR 24dB are 2nd
order and 4th order Linkwitz Riley alignments
respectively.
16.
With LFE
When a channel is set to Large or Large and Sub,
this channel can optionally reproduce LFE bass
which would normally be the sole responsibility
of the subwoofer channels. When set to None,
18
no LFE will be mixed into this channel. When
set to a figure between 0dB and -20dB, LFE bass
attenuated by that figure will be mixed into
this channel. This feature is useful when the
main channels have sufficient bandwidth AND
dynamic range to support the subwoofers in
creating an appropriate amount of bass sound
pressure in the room.
Items 16-21 apply to settings found in the ‘Delay,
Level, Limiter, and Phase’ section.
17.
Delay units
18.
Delay per Channel
19.
Level
Choose whether to measure channel delays in
meters (default), feet, or milliseconds.
Each channel should have distance/delay set
beteween that loudspeaker and the sweetspot.
You can define this in meters (default), feet, or
ms depending on your setting in 16.
Set the level of each channel in between -100dB
and +12dB in 0.1dB increments. Best practice is
to set other channels to a negative figure relative
to the loudest channel to avoid clipping when
possible. Global gain makeup can be applied to
the theater when the relative level of the theater
is too low (usually a result of a high degree
of correction due to Dirac Live’s mixed phase
SP4 Immersive Surround Processor
filters). Use global gain makeup judiciously to
avoid clipping.
20.
Limiter
To prevent distortion due to loudspeaker
overdriving or amplifier clipping, you may wish
to engage a limiter on a channel. When enabled,
a compressor will attenuate audio above the
threshold set by the Limiter Value for that
channel back down to that value. For instance,
if the limiter is enabled and set to -3dBFS, any
audio that exceeds -3dBFS will be reproduced
at -3dBFS. By their nature, limiters are not ideal
acoustic solutions, but this feature can prevent
subjectively worse sounding distortion, or in
extreme cases, damage to loudspeakers or
amplifiers. If you find that you are aggressively
using the limiter function, you are encouraged
to upgrade loudspeakers and/or amplification.
21.
Speakers may be set to one of the following 4
options:
•
Small: Channel is high pass filtered according to the
HPF frequency and slope. Bass is routed to subwoofer
channels according to frequency and slope defined
by LPF frequency and slope. Small speakers cannot
have subwoofer or LFE bass mixed in.
•
Large: Channel is not band limited. Channel can
have subwoofer and/or LFE bass mixed in.
•
Large and Sub: Channel is not band limited, but a
copy of bass for this channel is routed to subwoofer
channels as well. Set the frequency below which bass
should be sent to the subwoofer and the slope at
which the crossover occurs.
•
Large with Sub: This special case enables you to
effectively split a full range loudspeaker into a “small
speaker” plus “virtual subwoofer”. The HPF frequency
and slope define the characteristic of the “small
speaker” portion. LPF frequency and slope define the
virtual subwoofer characteristic.
Phase Invert
Check the box for any channel you in which you
wish to invert polarity.
Expert Bass Management
When it is desirable to fine tune subwoofer
integration beyond what is possible in Standard
Bass Management Mode, you may select Expert.
The flexibility within can achieve greater subwoofer
integration, but should only be used by calibrators
with sufficient skill otherwise comparably poor
results may be inevitable. Compared to Standard
mode, Expert includes the following features:
•
Additional Size/Filter options
•
Ability to separate HPF and LPF frequency and slope
per channel
•
1. Size/Filter
Ability to mix SUB bass (not just LFE bass) back into
channels set to Large, Large and Sub and Large with
Sub.
Output Mapping
Should you wish to map a physical analog
output channel to a loudspeaker other than
the default assignment, you may do so from
the Main Speakers page. Click Output Mapping.
Using the New Output column on the right of the
pop-up menu, select a new output channel. If you
choose a currently occupied new output channel,
that channel will be automatically reassigned. Save.

Full Range, Low Pass Filtered, Middle (band pass), or
High Pass Filtered audio. Two-way speakers will not
have Middle option.
Multi-way Loudspeaker Setup
During the initial Theater Definition setup, you
have the option of defining the front LCR speakers
as multi-way. Doing so will assign 2 or 3 output
channels to each speaker instead of 1. In this
configuration, more than 1 amplifier will be used
per loudspeaker, and the SP4 will perform the
crossover function for each loudspeaker.
All settings in the Bass Management section
detailed in “Individual Channel Adjustments” on
page 17 and “Expert Bass Management” on page
19 also apply and will not be covered again here.
This section only describes the differences notable
for multi-way loudspeaker configuration.
1. Signal
Note that in this example (Left Front is a 3-way
active loudspeaker), Each of the first 3 channels
receives the same Left Front signal.
2. Channel Name
By default, the channel names are named by
the signal they receive and proceeded by a
sequential number. For clarity, you may wish
to rename these according to the signal they
reproduce e.g. Left Front High, Left Front Mid,
Left Front Low.
3. Multi-way Management
Use this section to filter the signal for each
section.
•
20
Section: Choose whether each channel reproduces
•
Crossover Frequency: When the section is chosen
as anything other than Full Range, set the crossover
frequency for the Low and High Pass filters for each
section.
•
Slope: For each filter, select a slope. Options are
Butterworth 6dB / oct, Butterworth 12dB / oct,
Butterworth 18dB / oct, Linkwitz Riley 12dB / oct, and
Linkwitz Riley 24dB oct.
4. Delay
Set the delay of each section. For active multiway loudspeakers, it may be helpful to do this
in milliseconds and measure time-of-arrival
differences at the crossover point when using
LR or BT6 filters to time align each section of a
multi-way loudspeaker.
5. Level
Active multi-way loudspeakers almost certainly
have different sensitivities per module. Set the
relative level of each here. When possible, use
0 as the maximum figure and attenuate other
channels to match the loudest channel. You
can also set global makeup gain for the entire
theater as described in “19. Level” on page 18.
Channel EQ
Each channel can have up to 10 bands of parametric
EQ applied manually. To design EQ curves for
any channel, click the EQ button under the Status
column for that channel. Remember to SAVE often!

1. EQ Bypass
When developing a custom set of EQ per
channel, it is sometimes helpful to bypass
the entire group of EQ to check your progress
against the starting point.
2. Filter Shape
Each filter must begin with a variation of one of
5 types.
•
Low Pass: Continuously declining output above a
cutoff frequency at a defined rate.
•
High Pass: Continuously declining output below a
cutoff frequency at a defined rate.
•
Bell: Band pass or cut filter with a defined center
frequency, boost or cut amount, and Q.
•
Low Shelf: Boost or cut frequencies below a cutoff
frequency by a fixed amount.
•
High Shelf: Boost or cut frequencies above a cutoff
frequency by a fixed amount.
For LPF, HPF, and Bell filters, choose
Butterworth 12dB/oct, Butterworth 12dB/oct
inverse, Linkwitz Riley 12dB/oct, Linkwitz Riley
12dB/oct inverse, Butterworth 24dB/oct, or
Linkwitz Riley 24dB/oct.
3. Frequency
Each filter requires that a center or cutoff
frequency be specified. You can enter this
number directly in the text box or increment/
decrement by the amount chosen in the header
row using the +/- buttons to the right. Or, you
can use the slider.
4. Gain
Bell and shelving filters require that you set
the amount of boost or cut. You can enter this
number directly in the text box or increment/
decrement by the amount chosen in the header
row using the +/- buttons to the right. Or, you
can use the slider.
5. Quality Factor / Bandwidth
Bell filters require that you specify a Q. High Q
affects a narrow bandwidth, and low Q affects
a wide bandwidth. You can enter this number
directly in the text box or increment/decrement
by the amount chosen in the header row using
the +/- buttons to the right. Or, click a fractional
or multiple octave button to automatically
calculate Q.
6. Bypass / Reset
In the course of designing your filter, you may
wish to measure or listen to progress compared
to the absence of that filter. Click Bypass to
temporarily omit that filter from the aggregate
curve. Click Reset to reset that filter back to 0.
7. Copy to Channel
You may wish to duplicate your filter set to
another channel without manually rebuilding it
for each identical channel. Select a channel to
copy the current filters to and click COPY.
8. Channel Select
Select the desired channel to equalize here.

Child Theater / Sub Theater
You may optionally create alternate speaker
definitions in your theater with some restrictions.
For example, if you wish to have music playing
before the movie plays before everyone is seated
and quiet, you might only want that music playing
from the overhead speakers so as not to interfere
with conversation. In this case, you can define a
child theater so that stereo left/right audio is played
only through the top speakers (as in the example
above).
Child theaters behave just like zones or main
theaters in that they can be selected as outputs,
programmed into presets and can have multiple
profiles.
Note that though multiple Child theaters can be
designed per main theater, signal assignment is
common to all.
1. Create Child
From the Main Speakers page, Edit your theater.
Click Create Child. A window will appear with a
list of loudspeaker names and their channel ID.
2. Zone Signal
For each loudspeaker, select the signal to be
played. You may choose Stereo Left, Stereo
Right, Mono, or None. Subwoofer channels can
play Subwoofer signal or None.
22
3. Keep Dirac Profile
If you have created a Dirac profile for the parent
theater, you have the option to retain that
calibration for the child theater.
4. Save/Close
Save when done, or Close to cancel.
5. Bass Management / Delay Level Phase
Child theaters have comparably limited options
compared to full theaters. If a child theater
includes a subwoofer channel, the full range
channels are forced to small. In this case, you
can adjust the crossover frequency, slope and
subwoofer subsonic filter. If no subwoofer
channel is enabled for the child theater, the
main channels are forced to large. No Expert
Bass Management is available for Child
Theaters.
Zones
Zones are mono or stereo, and with or without
video output or can be dedicated to headphone
playback when used with an external headphone
amplifier like the BHA-1. Stereo Audio/Video and
Headphone Zones include provisions for adjusting
lip sync. Audio only zones do not. Zones occupy
unused channels and can play concurrently with
a theater or without one. Note that system wide,
only one input may be selected at once. That is, you
may not have different content playing to a zone
SP4 Immersive Surround Processor
than what is going to the main theater. Zones have
all the same features of a main theater except that
channels are always “large”, they cannot include
subwoofer channels, and they are limited to mono
or stereo. In order to control a zone, it must be
included in the preset that is currently selected in
the remote control. See “Presets” on page 28 for
more details.
Dirac Live
Dirac Live is a highly advanced calibration tool
which uses sophisticated mixed-phase filters to
compensate for loudspeaker and room deficiencies
in order to provide optimal acoustic performance
of your theater. Though all SP4s are compatible
with the Dirac Live Calibration Tool, it is an optional
purchase. The software license and calibration kit
are usually purchased by the installer, however,
they are available for purchase by the end user as
well. If you have not purchased the license and/or
calibration kit and would like to do so, please speak
with your Bryston dealer or with Bryston directly.
All Theaters, zones, and child theaters can be
calibrated with Dirac Live. Presuming you have a
license and calibration kit, prepare your SP4 for
calibration by following the steps below.
1. Define Speakers
For each theater or zone you will calibrate
using Dirac Live, ensure that you have correctly
defined each speaker’s Size/Filter, Frequency
and Slope, multi-way speaker definitions and
other Bass Mangement parameters. (“Individual
Channel Adjustments” on page 17)
2. Download and install Dirac Live
Calibration Tool Software
You can download a Mac or PC version of
the software at http://support.bryston.com/
downloads/SP4
Even if you own a Dirac Live license for another
branded product, it will not work for the SP4.
Only the StormAudio/Bryston branded version
of the software available from Bryston is
compatible.
Install the software on the laptop you will use to
calibrate the SP4. Enter the e-mail you used to
license the software and your password. Note
that the laptop will need to be connected to the
internet to validate your license.
3. Prepare Calibration Hardware
Although we recommend using the kit we
provide which includes the UMIK-1 USB
microphone, other hardware may be compatible
with the Dirac Live Calibration Tool. This guide
will only cover our hardware.
Connect the UMIK-1 to your laptop. Note the
serial number on the microphone. Navigate to
https://www.minidsp.com/products/acousticmeasurement/umik-1. Enter the serial number
to obtain your unique calibration files.
4. Choose Theater or Zone to Calibrate
From the Main Speakers (A) menu
in the SP4 web UI, EDIT (B) the
theater or zone you wish to calibrate.

5. Select Base Profile
Select the profile which will serve as the
basis for your Dirac Live calibration from the
dropdown menu.
6. Setup Dirac Groups
It is recommended that if your theater includes
multiple subwoofers, manually correct levels,
EQ, and delay for each. Then, group all the
subwoofer channels together for the purposes
of Dirac Live calibration. Also, manually build
any crossover and EQ settings for active
loudspeakers. Group separate elements of a
single active loudspeaker together e.g. Low,
Mid, and High components of the LEFT FRONT
should be in a single generator group. Click
the SETUP button (C) beside the Dirac button.

SP4 Immersive Surround Processor
-12dB in the channel’s meter. For each channel,
activate the test noise and correct the channel
volume using the corresponding slider (D) so
that the meter reads approximately -12dB.
Note that all channels are automatically listed
and subwoofers are automatically identified.
Remember that it is important that multi-way
speakers and subwoofers have already been
individually aligned and grouped therefore will
appear as one loudspeaker. Click Proceed (E).

Place the microphone in the exact sweet spot
of the room at ear level to begin. It must be in
the left-to-right center of the room since it will
be used for loudspeaker distance and level
calculations. Select the type of listening area
you wish to define. Chair is for a single listening
position, Sofa is a somewhat wider range of
listening positions, and Auditorium is the widest.
Start the measurement by pressing the START
button. The measurement waveform graphic is
updated in real time.
12. Measure Acoustic Response of
Remaining Positions
Once the first measurement is taken, that
position will turn green indicating successful
capture. Move the microphone to the next
position indicated in the diagram. Use the View
Menu to rotate the diagram to clearly identify
the next position. Repeat measurements for all
D
Clicking Auto Target (C) will generate a good
target response curve that respects the
bandwidth of the speaker and does not try to
apply too much gain to areas of low output.
Good target curve design is beyond the scope of
this document, but there are some key points to
remember.
•
Do not attempt to boost bass of a loudspeaker below
its low frequency limit as this will only lead to high
distortion and likely damage
•
High quality speakers usually benefit from limiting
the correction window to low frequencies.
•
Ideal curves usually have a slightly downward slope.
A loudspeaker may have a flat amplitude response on
axis, but will rarely be flat off axis.
•
Aim for identical target curves between channel pairs
(such as Front Left and Front Right) to obtain the best
spatial imaging.
Save the Target Curve (D) for use in another
channel or for other future use. Repeat for all
channels.

The SP4 has 4 independent DC voltage triggers
which can be configured to modulate the power/
standby status of connected equipment such as
projectors, source components, or amplifiers.
You may keep the default name for each trigger, or
rename them to something more descriptive. Each
trigger has the following options available:
•
Manual Switching: Turn on to enable a button on
the remote control interfaces that allows a user to
toggle the trigger manually.
•
Auto Switching: Enabled on Wake activates the
SP4 Immersive Surround Processor
trigger when the SP4 is powered on from standby.
It will not automatically deactivate the trigger when
the SP4 is placed into standby. Enabled on Input
makes the trigger available in the Input Menu. When
set to Y for an input, the trigger activates when that
input is selected from a remote interface. See “8.
Triggers” on page 13. Enabled on Preset makes the
trigger available in the Preset menu. When a preset is
selected in which a trigger is marked Y, the trigger is
activated. Note that Auto Switching trigger behavior
will override any Manual Switching behavior.

Note that all Bryston amplifiers since the SST series
feature SoftStart circuitry which slowly ramps up
power into the amplifier. Bryston amplifier triggers
may be daisy chained so that only once the preceding
amplifier is fully powered does the following amplifier
initiate it’s power up sequence thereby obviating the
need for a delay (or multiple triggers) when using
modern Bryston amplifiers.
Set the global lip sync delay for each theater, A/V,
and Headphone zone here. Max value is 250 ms.
System Setup
Enable fast boot to substantially decrease power on
time of the SP4 at the expense of greater standby
power consumption.

via remote control (input, volume, etc.) will
temporarily be shown in a large type so these
changes can easily be read from across the
room.
IR Remote Control Function Assignment
Parameters
•
Downmix zone: define whether the dedicated
downmix outputs feed an audio only zone or an
audio video zone. When A/V, lipsync adjustment is
available in that zone’s remote control functions, and
that zone’s general delay can be set using the setting
below.
•
Audio Control Range MAX: Set the maximum
allowable volume. +6db (default), +3dB, 0dB.
•
Volume Dim Level: To quickly attenuate the volume
(but not mute it), a user can click Volume Dim. Set the
level of attenuation here. Default is -20dB.
Expand Inputs and/or presets to assign up to 6
inputs and 5 presets to discrete buttons on an IR
remote control. Note that many “universal” remotes
also have the ability to cycle through all available
inputs or presets so even if you have more than 6
or 5 respectively setup, they can still be accessed
via IR. Remember that the SP4 has no front panel
IR receiver, so any IR commands need to be sent
to a module connected to the IR input on the back
panel.

Presets
Presets provide the installer with a way to group
specific settings together into a scene which can
be easily recalled by the end user from a remote
control interface. By using presets, the installer can
make use of the SP4 - a highly complex and capable
theater controller - extremely simple and enjoyable
to operate.
Each preset includes the following settings:
1. Preset Name
Title the preset according to the usage case. For
instance, if the entire family gathers together
to watch movies, Movie Night. Max of 12
characters.
2. Active
When Y, the preset shows up in the list of
selectable presets on the remote control. When
N, the preset information is retained, but not
available to select from the remote control.
3. Theater
The preset must include which theater to play.
The list includes Theaters, Child Theaters, and
if the optional SphereAudio license is installed,
SphereAudio. It does not include zones.
4. Profile
Each theater can have multiple profiles to
choose from. Select the profile which will be
loaded by default when the preset is chosen.
5. Dirac Room / Dirac Curve
If the theater is calibrated with Dirac Live, the
listening area and curve description you entered

in “15. Return to SP4 web UI” on page 26 will
be indicated.
6. Audio Zone
You may choose to route audio to 0 or more
zones as well. When zones are checked, they
are accessible and controllable from the remote
control when this preset is selected.
7. Triggers
When triggers are set to Auto Switching: On
Preset as described in “Triggers” on page 26,
they can be assigned to presets here.
8. Upmix
Though the upmixing behavior is accessible
from the remote control at all times, you may set
the default upmix for the preset here.
9. Delete / Create
Delete any unused presets by clicking Delete in
the correct row. Create a new preset by clicking
Create.
