SP31 MULTI-CHANNEL PROCESSOR USER GUIDE
ADVANCED CONNECTING
Power connection
Warning! Before connecting power check that
the required supply voltage, indicated on the
back panel, corresponds to your local AC
supply. If different voltage is stated on the type plate do
not connect the SP31 to the mains power. You then have
to seek advice from your dealer.
Connecting the mains power using the enclosed mains
cable.
Always disconnect the SP31 from the mains power before
connecting or disconnecting any of the cables.
Safety instructions
To prevent fire or shock hazard, do not expose this
appliance to dripping or splashing. No objects filled with
liquids, such as vases, should be placed on the SP31.
If you want to build in the SP31 you need to be sure to
allow space of at least 20 cm behind, 10 cm on both sides
and 30 cm above the top panel of the unit. This is to
prevent fire or damage. You also have to make sure that
the main switch is accessable.
Audio connections
Audio outputs
The SP31 Multi-Channel Processor provides one pair of
analog XLR outputs and four pair of analog RCA outputs.
The main outputs provide eight discrete analog audio
outputs for connecting to the power amplifiers and
loudspeakers in the surround system.
Audio inputs
The SP31 provides a total of 13 or 16 audio inputs, eight
digital and eight or four plus one external analog. Because
the SP31 is configurable, you have total flexibility about
which digital input you use for each of your digital
sources, and which analog input you use for each of your
analog sources. In addition, you can optionally use four
pairs of analog inputs for a single, multi-channel source,
such as DVD-A or SACD, called external.
The SP31 is supplied with a suggested set of sources
already set up, and you may choose to leave the inputs
assigned in this way. However, if you prefer, you can
reassign the inputs to sources in any way you prefer to suit
the equipment in your system, and the way you would like
to wire it up.
The SP31 provides one AES/EBU digital input, five
coaxial SPDIF digital inputs, and two optical TOS-Link
digital inputs.
The analog inputs that are provided are one XLR, seven
RCA’s or three RCA’s plus one external (RCA).
Video connections
The SP31 provides a choice of either component,
S-Video, or composite video connections. If your source
or monitor provides a choice of video connections we
recommend using the component or S-Video connections,
as these provide higher quality. However, we recommend
you first connect up and calibrate your system using the
composite connection.
Video inputs
The SP31 provides two component video, three
S-Video, and four composite video inputs.
Video outputs
The SP31 provides one component video, one S-Video,
and one composite video output. The on-screen display is
only provided on the S-Video and composite outputs.
