(1) CHANNEL 1-3 COMBO XLR / 1/4’ INPUT

The XLR mic inputs are an electronically balanced XLR type designed to accept mic level signals from any balanced or unbalanced low impedance (Low Z) microphone. The XLR jacks are configured for: Pin1 = ground, Pin2 = positive (+), Pin3 = negative (-). The XLR jacks have 15VDC phantom power applied to Pin2 and 3 for powering condenser microphones.

The 1/4” mono line inputs are designed to accept unbalanced line level signals such as those from keyboards, drum machines, or samplers.

(2) CHANNEL 4 XLR & 1/4” STEREO/MONO INPUTS

The XLR input is balanced, designed to accept mic level signals, and has 15VDC phantom power. The Left and Right 1/4” line inputs are for connecting stereo line level audio signals or only the Left/Mono jack can be used for connecting mono signals. The XLR input is defeated when either of the 1/4” inputs are used.

(3) CHANNEL 5 STEREO RCA INPUTS

The stereo RCA line level inputs can be used for connecting CD players, Tape Decks, and other audio equipment with line level outputs.

(4) MONO / STEREO MODE

When the Mono/Stereo button is out (stereo mode) the Left RCA Aux In is sent to the Left Speaker and Right RCA Aux In is sent to

the Right Speaker. When the button is depressed (Stereo mode), both L and R RCA input signals are mixed and sent to both speakers.

(5) EFF SEND CONTROL

The EFF SEND control adjusts the level of signal sent by each channel to the internal DSP (Digital Sound Processor). The signal sent is mono, post-Treble/Bass and will be affected by the CHANNEL FADER (8) setting.

(6) TREBLE CONTROL

Turn to the right to boost high frequencies, adding crispness too percussion from drum machines, cymbals and synths. Turn to the left to cut these frequencies, reducing sibilance or hiss. The control has a shelving response giving +/-10dB of boost or cut at 10kHz.

(7) BASS CONTROL

The bass control shelving response gives 10dB of boost or cut at 100Hz. Add warmth to vocals or extra punch to guitars, drums and synths by turning to the right. Turn to the left to reduce stage rumble, hum or to improve a mushy sound.

(8) CHANNEL FADER

The channel faders determine the output signal level to the Master Mix bus. They offer a smooth logarithmic taper more often associated with much more expensive consoles for optimum control of the signal.
