Depending on your SP4, your system will support up to 16 channels on Main Outputs
and 16 additional channels on Alternate Outputs for Dual Theater (with 16 Channel
RCA Outputs). For both sets of outputs, the Speakers conguration will follow the same ow,
as described below.

Please note that in case «ISP-O-Dual Theater» option is installed (Alternate Speakers), you should make
sure before selecting EDIT that the current Preset (therefore Theater) playing is from the same channels
bank: Main or Alternate Speakers bank.
!
At this stage, you can decide to EDIT the Theater 1 if the Layout meets your requirements.
If the case, go to step 5.6 (Bass Management & Distance). If not, go to step 5.1 in next page.
1. A single SP4 can manage several Theaters and switch from one to
the other during playback. A Theater can be dened according to
a Speaker Layout. By default a Theater is proposed in a 2.0.0.0 layout.
2. The mapping (Signal --> Output Channels) is shown on a per
Theater basis with dierent colour.
3. Output mapping can be changed. See section 9 (p 43).
4. New Theaters or Audio Zones (Mono/Stereo) can be added.

5.1) If the default Theater 1 doesn’t t your need, you have to replace it.
Press Edit then Delete as shown below.
5.2) To create a new Theater, select Create Theater, it will appear as shown below. By then
pressing Congure, you will go to the Speakers Layout selection and conguration steps
described in next page.
At this stage you can also create Stereo/Mono audio zones. We do recommend to rst dene the
Theater and use remaining channels for Audio Zones creation. See step 5.11 for Audio Zone creation.
Theater conguration is made in 3 steps: Creation (5.1 & 5.2), Speakers Layout selection (5.3) and
Speakers/Subwoofers Replication denition (5.4 & 5.5).

5.4) The basic layout can be tuned to meet your exact speaker conguration, being
multiway, with replication of some channels and/or with several subwoofers.
1. For LCR, you can dene as many ways as you want. Generally up to 3.
2. Replicate surrounds to meet seating row count.
3. Indicate the number of subwoofers required («0» if no Subwoofer required).
4. Dolby Atmos oers the option to simulate its ceiling speakers via «top ring»
speakers located in the main «front ring» speakers, so called Dolby Enabled
speakers. Dene here whether the Dolby Atmos top layer is reproduced with
such speakers and on which position you will place them.
5. Replication of other channels than Surrounds is possible: tick the Custom
Channel Duplicator to access the feature then enter numbers required for
each channel.
6. Save your conguration

5.6) Once the Layout has been dened and saved, you get access to the Speaker based
adjustments. The Theater is shown with its channels allocation. At this stage you can
connect the Speakers to the system (please go to section 9).
1. For each Theater, multiple audio Proles can be created. A Prole is the combination of the Speakers
denition (mutiways, levels, delay), Bass Management, Manual EQ and a Dirac lter design if applied
(see part 6).
2. We oer two approaches to Bass Management. A rst one that is the Standard Bass Management
as specied by Dolby and a second one that is a Custom Bass Management which opens up full access
to how the Bass should be managed/redirected in the system. The Custom mode has been designed for
installation where main channel speakers are used to reproduce the Bass. At this stage, you should select
which mode you want to use, considering that going from one mode to the other will reset the adjustments
made. To help you on this decision, the two modes are described in the next pages.
3. Adjust the crossover lters (Low, Middle and High) of LCR Multiways Speakers with cut-o frequency,
slope and phase. For more than three ways, additional lters can be adjusted via the Manual EQ (see 5.10).
4. With Manual EQ and the Dirac Filter Design corrections applied, the average output level in the Theater
might be lowered signicantly. You can boost this average output level between 0 to 12 dB, in 3 dB steps.
Note that setting a too high level can lead to clipping.

Standard Bass Management
1 2
1. In Standard Bass Management mode, you can dene how you want the bass to be managed for each
Speaker with three options: Small, Large and «Large and Sub». Small will cut the Bass and redirect them
to the Subwoofer channel. Large will keep the Bass in the Speaker. «Large and Sub» will keep the Bass
in the Speaker and also redirect them to the Subwoofer channel. Speaker characteristics should be
clearly known to ensure you don’t overload them with frequencies that they are not capable to
reproduce, especially in the case of small speakers limited in the low frequencies extension.
2. Cut-o frequency of the Bass Management is adjusted per Speaker, either by entering the required
value or using the - / + buttons. The crossover Slope can be either 12 dB or 24 dB per octave, with
Linkwitz-Riley type. Frequencies and Slopes are the same for both the Speaker and the redirected Bass lters.
3. When Speakers are set to Large, it is possible to redirect the LFE channel (Low Frequency Enhancement)
to them. Change this setting from None to a level between 0 to -20 dB, 0 dB being the highest.
