FRONT PANEL CONTROLS & CONNECTIONS

					FRONT PANEL
(1)				(2)	Note: 1 through 6 below are referenced to Channel 1. The other 3
					channels are identical.
					(1) GAIN CONTROL
					The Gain Control determines the proportion of the channel signal
(3)				(4)	in the mix,
					(2) REVERB CONTROL
					The Reverb Control adjusts the level of signal sent by each chan-
					nel to the internal Reverb DSP (Digital Sound Processor). The
					signal sent is mono, post-High/Low and will be affected by the
					channel Gain Control.
					(3) HIGH CONTROL
					Turn this control to the right to boost high frequencies on the
					channel, adding crispness to percussion from drum machines,
				(6)	cymbals and synths. Turn to the left to cut these frequencies, re-
(5)					ducing sibilance, hiss, or high frequency feedback. The control has
					a shelving response giving 15dB of boost or cut at 12kHz.
					(4) LOW CONTROL
					Add warmth to vocals or extra punch to guitars, drums and synths
					on the channel by turning this control to the right. Turn to the left to
					reduce stage rumble, hum or to improve a mushy sound. The con-
					trol has a shelving response giving 15dB of bust or cut at 100Hz.
(7)	(8)	(9)	(10)		(5) LINE INPUT
					The Line input is designed to accept balanced or unbalanced line-
					level signals such as those from keyboards, drum machines, or
					samplers. Use the GAIN control (1) to adjust for the desired level.
					If a balanced signal is to be connected to the line input, then a
					1/4” TRS (stereo) phone plug should be wired for: Tip = positive
					(+), Ring = negative (-), Sleeve = ground.
					(6) MIC INPUT
					The Mic input is an electronically balanced XLR type designed
					to accept signals from any balanced low impedance (Low Z) mi-
					crophone. It will be necessary to adjust the channel gain with the
					input GAIN control (1) to achieve a nominal operating level. The
					XLR jack is configured for: Pin1 = ground, Pin2 = positive (+), Pin3
					= negative (-).
					(Note: Only either the Mic or the Line input of a given channel can
					be connected at one time. Do not connect both simultaneously to
					the same channel.)

(7) MASTER — VOLUME CONTROL

This controls the final level of the signal output.

(8) MASTER — REVERB CONTROL

This controls the level of the reverb effects sound.
