(1) MICROPHONE Accepts a standard XLR male connector. Ground = shield / hot = signal input / cold = ground (shield).
Maximum -60dB~ -10dB signal level set by the gain control.
(2) LINE INPUT Accepts a standard 1/4 inch standard line connector. You can use unbalanced (tip/signal) and balanced
(tip/ring/signal). Used to connect keyboards or other electric instruments. Tip = positive / ring = negative / sleeve = ground.
(3) LOW CUT This switch cuts the input signal below 75Hz.
(4) GAIN CONTROL Adjusts the sensitivity from -60dB to -16dB for mics and -34dB to +10dB for line input.
(5) HIGH FREQUENCY EQUALISATION CONTROL Provides +/-15dB of fixed frequency equalisation that shelves at 12KHz.
(6) MID RANGE GAIN CONTROL Up to 15dB of cut and boost with a centre detent for off.
(7) MID RANGE CONTROL Semi-parametric with peaking response, Q fixed at 1 octave, sweepable from 100Hz to 8KHz.

(11) DIGITAL EFFECTS PROCESSOR Integrated effects processor which offers 99 different standard effects like reverb, chorus,
delay, pitch shift and various combination effects.
(12) PAN CONTROL The pan control sends continuously variable amounts of the post fader signal to either the Left & Right main
busses. In the centre position, equal amounts of signal are sent to the and right busses. As the control is rotated in either
direction, more signal is sent to the buss indicated in the direction of the rotation while less signal is sent to the other buss.
(13) PRE-FADER LEVEL (PFL) Pressing channel mode switch once disengages the stereo solo bus, and replaces it with a
separate mono PFL bus. PFL should always be used for gain setting.
(14) MUTE ON/OFF This switch, when pushed, sends the signal into MUTE and outputs from ALT 3-4.
(15) CHANNEL FADER You can adjust the volume of signal sources which connected to the relevant channel.
(16) & (17) STEREO 2 TRACK IN/OUT Used to record and playback mixer output.
(18), (19), (22) & (23) LINE IN Line level inputs.
(20) CTRL ROOM OUT Control room / headphone output.
(21) MAIN OUT This output signal can be connected with external amplifiers and speakers.
(24) HI MID Up to 15dB cut and boost at 3KHz mid and hi frequencies.
(25) LO MID Up to 15dB cut and boost at 500Hz mid and low frequencies.
(26) EFX PROCESSOR DIRECT IN External signals can be connected with the DSP input.
(27) AUX SEND Aux signal output jack.
(28) EFX SEND FX signal output jack.
(29) AUX RETURN AUX output signal return jack.
