Input Section

(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 of 1k ohms. The connector is wired as: Pin 1=shield; Pin 2=positive (hot); Pin 3=negative (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.

Features

(3) LEVEL CONTROL

The level 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 level controls on each unit.

(4) TREBLE 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 2 kHz.

(5) BASS 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 300 Hz.

(6) REVERB CONTROL

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