(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.
(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.
