Phono Input

I hear hum.

I hear
feedback

Only plug turntables into this input, do not plug in
CD players or other Line Level sources. Turn down
the INPUT GAIN CONTROL

Make sure you are using good shielded audio
cables. Some less expensive audio cables can be
susceptible to hum and interference. Keep your
audio cables away from AC power cables and AC
transformers. Make sure the mixer is not mounted
too close to high power amplifiers or lighting
equipment power supplies or ballasts. Make sure
your turntables are properly
grounded.

If you are using a microphone, make sure that
you are not too close to the speakers or
headphones. If you hear feedback on the phono
input, then the turntable may be mounted to close
to the speakers. Also, make sure the turntable
base is placed on a surface that does not vibrate
or resonate easily when the speakers are turned
up loudly.

Do the headphones work with the CUE pan in

make sure that the channel PFL switches are
engaged. Check the CUE LEVEL control.

Check to make sure the talkback switch is NOT
engaged on the microphone input. Check the
EQ sliders.

Check to make sure that the microphone levels
are turned all of the way down if a microphone

Is the Mic gain turned up? Does the microphone
require phantom power? This mixer does not
provide microphone phantom power.

In general, turn down the INPUT GAIN
CONTROL. The input signal may be too loud for
the input gain control setting that you were using.
Is the EQ on? Turn off the EQ. If the distortion
goes away, then you need to turn down the
INPUT GAIN CONTROL.
