MIXER FEATURES
INPUTS
1. Input faders - control individual source levels in the mix.
2. Hamster Control – reverses direction of the input fader.
3. Slope Adjust – sets the rate of volume increase as the Input
Fader is moved.
4. Input Toggle Switch (Transform) - selects which source will
be live to that channel based on what you have connected to the
rear panel input section. By removing the face panel the switch
can be rotated into any of eight positions.
5. Pre-fader Gain Control – adjusts the pre-fader volume for
cleaner sound. Use this in conjunction with the PFL Meter to
adjust the audio to an optimum level.
6. Channel EQ – adjusts the Treble, Middle, and Bass frequencies
respectively of the channel audio. Full rotation to the left
creates a “KILL” effect completely eliminating the sound from
that frequency area.
7. Panning – controls the mix of stereo audio available from the
channel. When moved to the left only the left speakers will be
heard, or to the right for the right speakers.
8. Process Loop – activates the process loop for the channel
assigned.
Note 1: The circuit has been designed to act as a send for an
external device such as a sampler if no return is plugged in.
Note 2: All process loops go to the same output. By pressing
process on two channels at the same time, the audio will bleed
through.
9. PFL Meter - used to adjust the PFL levels, accurately match
channel levels with the Pre-fader gain controls before mixing
them together. The idea is to properly match PFL inputs, not
the input with the stereo output meter!
MICROPHONE
10. Mic Gain Controls – controls the DJ Mic volume for the
Neutrik™ “Combo” connector on the front panel.
11. Treble and Bass Controls – for fine-tuning the tone of your
voice on both mics through the sound system. The controls are
detented for setting tone "flat". For best results, use a dynamic
cardioid microphone.
12. Mic Process Loop – activates the process loop for the
microphone.
13. Neutrik™ “Combo” connector - allows connection of either a
1/4” jack or an XLR jack. This is ideal for connecting an XLR
gooseneck directly into the mixer.
HEADPHONE CUEING
14. Channel Cue Assign - are used to route Pre Fader Level (PFL)
channel audio to the Monitor Section. The channel faders do
not control the Cue volume.
15. Headphone Mix - controls the mix of PFL and PGM signals to
your headphones. When the slider is moved to the left, all you
will hear is the cue source. When the slider is all the way to the
right, you will hear what is playing through the master output.
By blending, beats can be matched exactly and segues can be
smooth when a song is cued.
16. Headphone Level – adjusts cue volume.
17. Split/Blend Cue – controls how PFL and Program audio are
sent to your headphones. In split mode, the PFL audio can be
heard in your left ear and PGM audio can be heard in your right
ear. In blend mode, both PFL and PGM can be heard in both
ears.
18. Headphone output – for your 1/4” or 1/8” headphones.
OUTPUTS
19. Master Fader – controls the overall output level.
20. Booth/Zone Fader - controls speaker volume for a remote zone
or booth monitors.
NOTE: This can also be used to supply line level audio to a
lighting controller or to lights that are sound activated.
21. Stereo Auto Peak Hold Level Indicator- quickly and
accurately tracks level of audio output. The red LEDs for +3dB,
+5dB and +8dB hold program peaks for a second or two. With
peak metering, it's OK to be "in the red" as long as +5dB or
+8dB aren't constantly lit. When using as a master output
meter, set the crossover, equalizer and power amp inputs to
avoid distortion at each step in the audio chain. Proper attention
to the peak meter results in the punchiest possible sound without
audible distortion.
CROSSFADER
22. Infinity™ Crossfader - achieves clean segues between the two
input channels selected by the Crossfader Assign. See page 10
for a more detail description of this exciting new design.
23. Crossfader Slope – determines how quickly the audio from the
opposing side of the crossfader activates. A tight curve (hard
right) turns on the opposing audio signal with very little
crossfader movement. A loose curve (hard left) makes very long
and smooth segues in transition.
24. Hamster switch with Off position – reverses the direction of
the crossfader. In the center position the crossfader is
deactivated.
25. Crossfader Assign – channels 1 or 2 can be assigned to the left.
Channels 2 and 3 can be assigned to the right. If for example
channels 1 and 3 were selected then "Hard left" selects Channel
1 and "Hard right" selects Channel 3. With the crossfader
centered, both assigned channels are live. Use the crossfader for
fast and seamless segues from one selected channel to the other.
Note: If channel 2 is selected on both sides, the crossfader will
turn off channel 2 in the left position and turn it on in the right
position
Note: The crossfader is user replaceable in case of failure.
Simply unscrew the two large screws that hold it in place, lift it
out and disconnect its cable. Re-attach the new crossfader and
screw the mounting plate back onto the unit - you’re back in
business!
