SP31 MULTI-CHANNEL PROCESSOR USER GUIDE
SETTING UP THE SPEAKERS
Setting the speaker levels
You should next set the speaker levels, so that the sound
from each speaker is equally loud at the listening position.
The SP31 allows you to set the levels for the GENERAL
layout in two alternative ways:
• The AUTOMATIC option (where fitted) allows you to
connect a microphone to the SP31 to set the levels
automatically for all the loudspeakers.
• The MANUAL option allows you to adjust each
speaker to equalize the loudness at the listening
position.
You can also manually define levels for the DOLBY
DIGITAL, DTS, and OTHER layouts which add to or
subtract from the GENERAL levels when the source is
Dolby Digital, DTS or analog.
To change the speaker levels automatically
Note: This option is not available in all markets.
• Connect the microphone to the MIC input on the
back panel, and position it at the listening position.
•Use the SELECTOR on the front panel or the or
buttons on the remote control to highlight SET
LEVELS in the SETUP MENU. Then press the
button on the front panel or the SELECT button on
the remote control to select the required option.
The SET LEVELS menu will be displayed:
•Use the SELECTOR on the front panel or the or
buttons on the remote control to highlight OUTPUT
LEVELS - AUTOMATIC. Then press the button
on the front panel or the SELECT button on the

•Highlight each of the speakers in turn, using the
SELECTOR on the front panel or the or buttons
on the remote control, and use the VOLUME control
on the front panel or the or buttons on the remote
control to adjust the delay.
Adjust the value according to the distance of each speaker
from the listening position. You can adjust the delay for
each speaker between 0 and 100 feet (0 and 30 m), equi
valent to 0 to 100 milliseconds in 1 milli-second steps.
•Press the button on the front panel or remote
control to return to the SETUP MENU.
Setting the speaker delays
The next step in setting up the loudspeakers is to set the
speaker delays to ensure that the sound image is correctly
focused.
Delaying the sound from a speaker by 1 milli-second is
equivalent to moving the speaker one foot (0.3 m) further
away from the listener.

or buttons on the remote control to highlight the
