OUTPUT TYPES
This chapter explains each of the outputs on the Harbinger L502/802 mixer and their level controls.
MAIN OUTS
The Main Outs are line outputs. They will work with either balanced
or unbalanced cables. The Main Mix fader controls the level of the
Main Outputs. You might plug the main outs into a PA amplifier or a
mixdown recorder.
All of the channels should show up at the Main outputs. If they don't,
make sure that the "Aux RCA to Mix" button isn't pushed.
CONTROL ROOM OUTPUTS (CNTL RM OUT)
*
The Control Room Outputs are a separate set of outputs for the mixer
to listen to. In a home studio, you might plug these into a set of
powered studio monitors. The Cnrl Rm|Ph knob controls the level
going to the control room outputs (and the headphones.)
There are three sources that can be sent to the Control Room
Outputs. Usually, you listen to the same mix that's coming out of
the Main Outs. If the Aux RCA to Phones (Control Room) button is
pressed, only the Aux RCA input will be heard through the Control
Room outputs.
If the Aux Send to Phones (Cntl Room) is pressed down, the aux send
will be heard through the Control Room outputs. This can be useful
when preparing a headphone mix for an artist.
PHONES
This is a headphone-level output. It is designed to drive a pair of
headphones with a balanced ¼" connector. If your headphones
have a 1/8" stereo jack, you will need an adapter to plug them into
the mixer (included with most professional headphones.)
Note that the headphones and the control room outputs are linked
– both the mix and level. If you press Aux RCA to Phones (Cntl Rm),
the Aux RCA input will be sent to both the control room outs and the
headphones. If you turn the control room level all the way down,
there will be no signal in the headphones.
AUX SEND
*
This jack sends the aux buss out of the mixer. Turn up the Aux knob
on any channel to send it to the Aux Send output. See page 9 for
more information about the aux buss.
AUX RCA OUTPUT
This is a pair of unbalanced line level outputs. They are just a copy
of the Main Outputs. If you turn the Main Mix fader down, the level
is also reduced here.
TROUBLESHOOTING
In this chapter, we'll discuss common problems and their solutions, as well as who to contact if things go wrong with your mixer.
TROUBLESHOOTING MATRIX
A microphone is plugged in, but you don't see any level on the
main meters.
• Are the Gain and Level knobs turned up?
• Is the Main Mix fader turned up?
• Is the Aux RCA to Mix, Aux RCA to Phones, or Aux to Phones
button pressed in?
• If the mic needs phantom power, is the phantom power turned
on? (Try it if you aren't sure.)
• Try a different microphone cable and/or microphone.
• Check the power connections, your power strip, extension
cords, etc.
You can hear everything, but it's very noisy.
• Are all of the level controls turned up very high? Try turning
those down and the gain controls up.
• Try turning down channels one at a time. If there is one
channel that is contributing most of the noise, try fixing that at
the source.
You can see level on the meters, but can't hear anything through
the control room* speakers.
• Is the Aux to Phones/Control Room* or Aux RCA to Phones/
Control Room button pressed in?
• Are the monitors switched on?
• If only one output is working, try switching the left and right
outputs. If the same channel isn't working, the problem is with
the speaker.
