S-3/PR
For simplified integration of an ,adV surround
sound processor, the S-3/PR input can be
set to operate as a unity gain stage. In this
Theater Throughput
TM
mode, when the
S-3/PR input is selected, the volume and
balance controls of the KAV-250p are dis-
abled. Volume control is transferred from the
KAV-250p to the A/V surround sound
processor connected to the S-3/PR input.
The left and right channel volume settings
become independent from the volume con-
trol of the KAV-250p and the overall system
level is determined exclusively by the A/V
surround sound processor.
NOTE: The factory default position sets the
S-3/PR input as a standard input.
To enable this option, it is necessary to
remove the top cover of the KAV-250p.
1. Unplug the KAV-250p from the AC out-
let.
Remove the KAV-250p top cover screws
with the supplied T-10 Torx wrench. Lift
the cover from the KAV-250p.
3. Find the section labeled Input Configure
located behind the faceplate directly in
back of the KRELL logo. The factory
default setting is shown in Figure 1
below. Remove the jumper from the S-3
side and place it on the side labeled
proc as shown in Figure 2 below.
4.
Place the top cover back on the KAV-250p
and insert the cover screws.
5.
Plug the KAV-250p back into the AC out-
let.
