Operation
After making all the necessary connections,
follow these steps to operate your mixer.
1. Set
POWER ON/OFF
to
ON
to turn on the
mixer.
Note: To avoid a possible popping
sound, always turn on the mixer before
you turn on the amplifier.
2. Turn on the output amplifier and leave
its volume set to minimum.
3. Set the selected audio input source's
volume to its minimum setting, turn it on,
and set it to play (or continuously talk
into the microphone).
4. Set the corresponding
CHANNEL 1
,
CHANNEL 2
,
CHANNEL 3
, or
CHANNEL 4
volume level to about
6 – 10
.
Notes:
• When mixing more than one audio input
source, set all the volume level controls
of the audio input sources to the same
setting.
• Adjust the mixer's fader controls to get
the best mix. If the overall sound level is
too low with the fader controls at
10
,
increase the output amplifier's volume.
5. Adjust the output amplifier's volume
level control to the desired volume.
6. When you are finished mixing, set
POWER ON/OFF
to
OFF
and turn off the
output amplifier and all the audio input
sources.
MIXING MONO OR STEREO
When you set the mixer's
MODE STEREO/
MONO
switch to
MONO
:
• The mixer routes the input signal of any
monaural source connected to only one
of the mixer's line inputs (
LEFT
or
RIGHT
)
to both output channels.
• The mixer changes the stereo input sig-
nals connected to the mixer's line inputs
(
LEFT
and
RIGHT
) to monaural.
To mix mono signals with stereo signals, set
STEREO/MONO
to
STEREO
.
Note: For mono amplifiers (found in some
PA systems), it is best to set
MODE STEREO/
MONO
to
MONO
.
VOICE-OVERS
You can mix an audio input source contain-
ing prerecorded music or special sounds
while you talk into a microphone. This lets
you mix your voice with music.
1. Set the mixer's fader controls for the
music source you want to mix to the
desired volume level (before you begin
talking).
2. While the music plays, talk into the
microphone and adjust the fader con-
trols for the microphone and music
source so you can hear yourself over
the music.
3. During pauses in speech, return the
music source's fader controls to their
original positions.
4. When you finish speaking, set the micro-
phone's fader control to
0
and the music
source's fader controls to their original
positions.
