The M2500 provides four stereo input channels,
allowing line-level stereo sources such as sub-mixers,
effect processors, and CD players to be input. Of the
stereo input channels 1–4, channel 1 provides both
XLR and RCA phono input jacks, and you can select
and use one of these. Channels 2–4 provide a pair of
TRS phone input jacks. For this reason, there are
slight differences between the controllers of channel 1
and channels 2–4. Our explanation here will be based
on stereo input channel 1, and any differences for ste-
reo input channels 2–4 will be explained later.
A GAIN A control
This adjusts the input sensitivity of the signal that is
input from the XLR connectors of the ST CH 1
INPUT A jacks (page 26). Levels of +10 dB to –30 dB
are supported. If the A/B select switch (3) is in the B
( ) position, this control will have no effect.
B GAIN B control
This adjusts the input sensitivity of the signal that is
input from the RCA phono connectors of the ST CH
1 INPUT B jacks (page 26). Levels of +10 dB to
–20 dB are supported. If the A/B select switch (3) is
in the A ( ) position, this control will have no
effect.
C A/B switch
This selects the input jacks that will be used for stereo
input channel 1. When the switch is in the upward
position ( ), the ST CH 1 INPUT A jacks can be
used. When the switch is in the downward position
( ), the ST CH 1 INPUT B jacks can be used.
Note: Since stereo input channels 2–4 have only
one set of inputs, only one GAIN control is pro-
vided. (Nor is there an A/B select switch.) This
control will adjust the input sensitivity of the sig-
nal that is input from the TRS phone connectors
for the ST CH 2–4 INPUT jacks (page 26). Levels
of +10 dB to –30 dB are supported.
