Introduction
Welcome to the Primare SP31.7 Multi-Channel Processor! This chapter introduces you to its key
features, and explains how you can take advantage of its configurability to create a system
perfectly suited to your requirements.
WELCOME TO THE SP31.7 MULTI-CHANNEL
PROCESSOR
The SP31.7 provides a comprehensive range of features to
make it ideal as the heart of an unparalleled music or home
entertainment system:
Exceptional processing performance
The SP31.7 uses proprietary DSP circuitry developed by
Primare, providing better analog performance than the
current off-the-shelf circuits used in many other surround
processors, resulting in a very high standard of multi-channel
audio reproduction. The SP31.7 provides up to 192kHz/
24 bit processing to accommodate all the current
multi-channel audio formats and allow for expansion as new
formats are introduced.
Flexible range of inputs
The SP31.7 provides a range of inputs flexible enough to
cater for virtually any combination of sources including:
seven analog RCA inputs, one analog XLR input, five coaxial
digital inputs, two TOSlink optical digital inputs, and one
AES/EBU digital input.
Video switching
The SP31.7 provides two component video inputs, three
S-Video inputs and four composite video inputs, allowing you
to switch up to nine audio-visual sources.
ideal mode for each type of material, including Dolby Pro
Logic II, an improved version of Dolby Pro Logic, and several
new processing modes designed to provide superb results
with eight-channel systems from Dolby Digital and DTS
encoded materials.
Multi-channel analog input
In addition to decoding encoded multi-channel sources, the
SP31.7 provides a discrete eight-channel analog input for a
DVD audio or SACD player that provides a multi-channel
output.
Full configurability
The SP31.7 is fully configurable from either the front panel or
remote control, using a simple set of on-screen menus, to
allow you to set it up with the exact combination of sources
and outputs that you want to use for your own system. The
SP31.7 is supplied already set up with a standard set of
sources, designed to cater for the most usual combination of
inputs and outputs in a typical system, but you can modify
these or define your own sources with total flexibility.
Intuitive user interface
In keeping with the philosophy of the Primare range of
systems, the SP31.7’s powerful range of features can be
controlled through a very simple and intuitive interface,
designed so that it will not distract you from the pleasure of
listening to music or watching movies on your system.
Digital Surround Processing
The SP31.7 can decode multi-channel sources encoded in the
Dolby Pro Logic, Dolby Digital (AC-3), or DTS formats to
provide eight discrete output channels for up to eight
loudspeakers in a surround system. The SP31.7 provides a
wide range of processing options to allow you to choose the
§1 Introduction 26/7/02, 12:51 pm1
In fact almost all the features of the SP31.7 can be accessed
through just two front panel controls and four push buttons;
alternatively the same degree of control is provided through
the C31 Remote Control supplied with the SP31.7.

> Introduction
Easy to set up
The SP31.7 is also exceptionally easy to set up for a
perfectly balanced surround sound. Simply plug a microphone
into the appropriate SP31.7 input, and position it at the
listening position. The built-in calibration test will then
balance the level of each output to give a correct sound
image for your system and the room you are listening in.
USING THE SP31.7 WITH OTHER PRIMARE
PRODUCTS
Although the SP31.7 is flexible enough to work with virtually
any other equipment you have in your system, it is ideal for
use with the other products in the Primare range, including
the Primare A30.5 Multi-Channel Amplifier and the Primare
V25 DVD Player. A particular benefit of using the SP31.7
with the Primare DVD Player is that you can control both
units with the single remote control, to give you a fully
integrated system with the simplest possible user interface.

Using the SP31.7 Multi-Channel Processor
This chapter explains how to operate the SP31.7 Multi-Channel Processor, using either the front
panel controls or the direct remote control commands.
FRONT PANEL CONTROLS
Almost all the functions of the SP31.7 Multi-Channel
Processor can be accessed using the two front panel controls
and four push buttons, and information about its operation is
displayed on the front panel display:
(A The INPUT SELECTOR selects an input, or operates
the on-screen menus.
(B The MENU button selects the on-screen menus.
(C The SELECT button selects the current menu option.
(D The LEVEL button selects which setting you change
with the VOLUME control.
(E The STANDBY button switches the SP31.7 to standby.
(F The VOLUME control changes the volume, changes a
setting selected with the LEVEL button, or operates
the on-screen menus.

the arrow keys on the remote control.
SELECTING A SOURCE
The SP31.7 Multi-Channel Processor allows you to define up
to 16 sources. Each source can use one of the eight digital
and eight analog inputs, and any source can be combined
with one of the video inputs. Alternatively, a multi-channel
source can be defined using analog inputs 5 to 8.
When the SP31.7 Multi-Channel Processor is first supplied
the eight standard sources shown opposite are already set
up for you.
You can simply disable any of these sources that you do not
need; see

To select a source
• Turn the INPUT SELECTOR control on the front panel
until the name of the source is shown on the front panel
display.

CHANGING THE VOLUME
The SP31.7 allows you to vary the volume from 0 (silence) to
99 (maximum volume), where each step is equivalent to
0.5dB.
To change the volume
• Rotate the VOLUME control on the front panel, or press
the > or < buttons on the remote control.
The current volume setting is shown on the front panel and
on-screen displays:
To mute the sound
• Press the MUTE button on the remote control.
To restore the sound to its original volume
• Press the MUTE button again.
CHANGING THE BALANCE, CENTER, SURROUND,
SURROUND BACK, AND SUBWOOFER LEVELS
You can independently change the balance, center level, side
levels, rear levels, and subwoofer level to alter the balance of
sound in your surround system.
Changing the balance alters the level of both the left and
right main loudspeakers to shift the position of the stereo
image, keeping the overall level of the sound the same. The
other adjustments change the level of the corresponding
speaker(s) without affecting the remaining speakers in the
surround system.
To change a level
• Press the LEVEL button on the front panel, or the
BAL/SETUP button on the remote control, until the
display shows the current value of the level you want to
change.
AC-3 P.L
C +2.0
For example:
5
VOLUME
The sound is also restored to its original volume if you
increase the volume.
• Use the VOL UME control on the front panel, or the >
and < buttons on the remote control, to adjust the value
of the level.
After a short delay the display will revert to volume.
The levels are selected in the sequence shown in the
following table:
Display Level Range
L, Balanced, R Balance Balanced to -9.5dB to OFF
CCenter -10.0dB to +10.0dB
SS Surround -10.0dB to +10.0dB
SB Surround back -10.0dB to +10.0dB
S Subwoofer -10.0dB to +10.0dB
