Stereo input channels

The M3000A provides four stereo input channels. Ste-
reo sound sources such as sub-mixers, effect proces-
sor, or CD players can be input to the INPUT A jacks
(XLR connectors) or INPUT B jacks (RCA phono
connectors) located on the rear panel.
A GAIN A control
This control adjusts the input sensitivity of the signal
that is input from the XLR connector INPUT A jack
(rear panel 4). The level range is +10~ –30 dB. When
the A/B select switch (3) is in the B position (
this control will have no effect.
B GAIN B control
This control adjusts the input sensitivity of the signal
that is input from the RCA phono connector INPUT
B jack (rear panel 5). The level range is +10~ –20 dB.
When the A/B select switch (3) is in the A position
( ), this control will have no effect.
C A/B select switch

channel will use. When the switch is in the upward
position ( ) the INPUT A jack can be used. When

D EQ controls
This is a four-band equalizer which allows 15 dB of
boost/cut for each band. The HI-MID and LOW-MID
bands allow you to switch between two settings of Q
(steepness). The center frequency, Q values, and gain
range for each band is as follows.
Center

HI 20 kHz
HI-MID 3 kHz
LO-MID 800 Hz
LO 50 Hz
E EQ switch

when the switch is pressed down (
F M1–M8 switches
These switch on/off the signal which is sent from the
stereo input channel to MIX buses 1–8.
