1
Mic Level Control
Adjusts the Level of the MIC Input. The OL (overload) indicator lights when the maximum mic level has been reached, 3
dB before clipping. If this lights up, either turn the MIC LEVEL down, or stop yelling.
2
Program Input Selectors
Provide selection of LINE 1, LINE 2, USB 1 or USB 2 Inputs for each of the PROGRAM A or PROGRAM B channels. LINE
Inputs may each be set for PHONO or LINE level via the rear panel switch (see Rear Panel 6).
3
Program Low And High Tones
Adjust the equalization for each of the PROGRAM channels. Pointing these controls straight up at their center detents
takes the tone controls out of the signal path. This is not designed to be the only equalizer in the system, this is intended
to provide EQ between varying program materials. We recommend an external graphic equalizer for the best system
sound, connected between the HOUSE OUTPUTS and the amplifier.
4
Program Level Controls
Set the volume of each PROGRAM INPUT, as you would expect! These controls are pre-Crossfader, so both Program
Level controls also depend on the Crossfader setting (see 6).
5
Program Meter
This four-segment meter shows signal presence (at -24 dBu), optimum signal level (at around 0 dBu), and a warning to
turn down the associated LEVEL control if the +12 dBu indicator lights up.
6
Active Crossfader
Controls the mix of PROGRAM A and B LEVELS in a logical manner. When the Crossfader is all the way left, only
PROGRAM A is heard. When it’s all the way right, only PROGRAM B is heard. When it’s in the middle, both PROGRAM
A and B are mixed together equally. This is an Active Crossfader™ which uses a VCA to deliver an extended life with
reduced travel noise, but to insure trouble-free operation, see Fader Cleaning on page 4.
7
House Level Meter
Adjusts the Output Level of the Main-mix to the HOUSE Outputs.
8
Cue Switches
Select Program A or B in any combination to the PHONES. The associated yellow indicator lights when a CUE is
activated and pressed in. Depressing a button sends Program signals to the CUE side of the PAN control. For example,
when the Crossfader is to the left (playing Program A to the House), listen to CUE B (Program B) on the headphones to
audition, match beats or prepare a starting point.
9
Pan Control
Changes the relative levels of the Cue and Program mixed together in stereo to the PHONES. Adjust this control
anywhere between Program and Cue:
PGM follows the Main-mix (House) Output.
CUE is determined by the CUE switches and only goes to the headphones.
10
Phones Level And Headphone Jack
As you guessed, plug your headphones in here and adjust the overall volume with the LEVEL control. CUE 8 and PAN
9 select the source.
11
Power Indicator
Illuminates to let you know the MP 4 is plugged in and ready to go.
