(1) 3-PIN LOW IMPEDANCE MICROPHONE INPUT
This input is for 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 ohm. 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 a line-level device such as a cassette
player, CD player, return or radio. 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 devices). 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) 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.
(5) REVERB CONTROL
This is used as a send control to the reverb bus. It controls the amount of reverberation added to the input signals.
(6) MASTER LEVEL
This controls the overall volume level of the entire amplifier. Typical operation is between 4 and 8.
(7) MASTER REVERB
This controls the level of Reverb that is added back to the mix.
(8) TAPE VOLUME
This controls the level of the playback inputs (RCA jacks on rear panel).
(9) MASTER EQ
These are used to adjust the overall EQ of the master mix. Since these cover three frequency bands (+/-15 dB),
they will add or diminish the low, mid or high frequencies in the sound.
(10) POWER
This switches the unit on or off. When the unit is powered up, a blue LED will illuminate.
