Radio Shack 4-CHANNEL STEREO SSM-1750 - Manual (Page 10)

10 Operation
Important: Note the AUX LEVEL setting,
so each time you want to mix that
source you can set the control to the
correct setting.
Notes:
• If it was necessary to set the AUX LEVEL
control to 10 to get a reading of up to 0
on the VU meter, then set AUX LEVEL to
about 8 and adjust the AUX GAIN control
to get a reading of up to 0 on the VU
meters. (See “Using Gain” on Page 11.)
• If the above does not work, set AUX
GAIN mid level and rotate MASTER
clockwise until you get a reading of 0 on
the VU meters.
• Readjust MASTER affects the level of the
previously set input sources. You must
readjust those sources until you get a
reading of up to
0 on the VU meters for
each.
5. Stop playback of the selected input
source.
MIXING THE INPUTS
You can connect input signals from up to 12
audio sources, select any two of the channel
input sources, then mix them so only one or
both play through your sound system.
Mixing requires three operations:
• Playing one input source.
• Monitoring the next input source.
• Switching to the next input source.
You can start with either of the two selected
sources.
To prevent prematurely mixing audio sourc-
es, set all volume level controls to
0 .
To avoid sudden and inaudible sound out-
puts from any audio devices that you con-
nect to the mixer, be sure to set their power
controls to off and any tone controls to flat.
Playing One Input Source
1. Set ASSIGN A to the desired source,
then set CROSS FADER to A .
2. Select the mixer's input — CH 1 , CH 2 ,
CH 3 , or CH 4 .
3. Set the input selector control to the input
source you want to play first through
your sound system.
4. Adjust the receiver's or amplifier's (not
the mixer's) volume control to the
desired volume.
Make sure the first input source's vol-
ume level slide control is set to the cor-
rect preset position.
5. Start playback of the input source.
Monitoring a Second Input Source
Monitoring a second input source's signal
level requires selecting the input source that
is not currently playing, finding the desired
section you want to mix, then adjusting the
source's sound level so it matches the vol-
ume level of the source currently playing.
1. Connect and put on headphones.
Note: You can listen to one channel
through the headphones while the other
channel is playing through the sound
system.
2. Set ASSIGN B to the second input
source.
3. Set CUE ASSIGN to the audio input
source ( CH 1 , CH 2 , CH 3 , or CH 4 ) you
want to monitor.
