PIN LOW-IMPEDANCE Microphone Input, Main Control

Front Panel

(1) 3-PIN LOW-IMPEDANCE MICROPHONE INPUT

	This input is for typical balanced, low-impedance microphones. It will automatically provide
	phantom power (15V) for condenser mics or active direct boxes. This has an input impedance	1
	of 1k ohms. The connector is wired as: Pin 1=shield; Pin 2=positive (hot); Pin 3=negative	1

	(cold).

(2) 1/4" LINE/HIGH-IMPEDANCE INPUT

This input may be used as either a high-impedance microphone input or for line-level devices such as a cassette player, CD player, video projector or laptop. This will also allow connection from an electric guitar, bass or keyboard. It is a two-conductor input with an impedance of 10k ohms.

(3) PAD

Decreases input sensitivity 20 dB to compensate for high-amplitude input sources.

(4) MAIN CONTROL

The main control for each channel sends the signal to the master mix bus. Typical operation is between 4 and 8 (dependent upon the input devices) but should be lower than the master level. Please remember that this acts like a preamp, so if you are using a device that has a volume output control (i.e.: a tape or CD player) you will need to do some level matching by adjusting the main controls on each unit.

(5) HIGH TONE CONTROL

This is used to adjust the overall tone of the individual inputs. Since it is a cut or boost control (+/-15 dB), it will add or diminish presence frequencies in the sound beginning at 8 kHz.

(6) MID TONE CONTROL

This is used to adjust the overall tone of the individual inputs. Since it is a cut or boost control (+/-12 db), it will add or diminish presence frequencies in the sound beginning at 2.5 kHz.

(7) LOW TONE CONTROL

This is used to adjust the overall tone of the individual inputs. Since it is a cut or boost control (+/-15 dB), it will add or diminish bass frequencies in the sound beginning at 100 Hz.

(8) EFFECTS CONTROL

This is used as a send control to the effects bus. It controls the amount of reverberation added to the input signals.

(9) MONITOR LEVEL

This controls the overall volume level of the entire amplifier. Typical operation is between 4 and 8.

(10) EFFECTS ECHO

This controls the level of the echo and delay that is added back to the master mix.

(11) DIGITAL EFFECTS

LED digital display of the currently selected Digital Effect.

(11a) DIGITAL EFFECTS SELECT

This controls the character of the reverb that is added back to the master mix. Each Digital Effect selected is analogous with changing the rate at which the reverb echo decays.

11a

(12) EFFECTS OUT

This sends the effects to the Effects Out Jack (15).

(13) EFFECTS SWITCH

This push button switch enables/disables effects.

(14) PHANTOM POWER SWITCH

This switch allows 48 volt phantom power for support of electret microphones.

(15) EFFECTS OUT JACK

Level of effects controlled by Effects Switch (12).

(16) FOOTSWITCH JACK

This jack provides the connection of the optional remote footswitch. Footswitch is used to enable/ disable reverb effects.
