INPUT SECTION FEATURES:
(1) 1/4 Line/High Impedance Input: This may be used as either a high impedance microphone input
or a line level device such as: tape players, CD player, effects returns or radios. It will also allow
connection from an electric guitar, bass, or keyboard. It is a 2-conductor input with an impedance of
10K ohms. Both the high and low impedance inputs may be used simultaneously.
(2) 3 Pin Low Impedance Microphone Input: This input is for balanced low impedance microphones.
Phantom power (15 volts) for condenser microphones is always on and available. It has an input
impedance of 1K ohm. The connector is wired as: Pin 1 = shied; Pin 2 = positive (hot); Pin 3 = negative
(cold).
(3) Volume Control: This is the volume control for each channel. It sends the signal to the master mix
buss. Typical operation is between 4 and 8, dependent upon the device(s) on that channel, Please
remember that it acts like a pre-amp, 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 the adjust the overall tone of the individual inputs. It is set at 5Khz. Since it
is a cut or boost control, (+/- 15dB) it will add or diminish presence frequencies in the sound.
(5) Reverb Control: This is a send control to the reverb buss. It controls the amount of reverberation
added to the input signals.
MASTER SECTION:
(6) Master Volume: 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 internal reverberation added back to the mix.
(8) Tape Volume: This controls the level of the playback inputs (RCA jacks on rear panel).
(9) Master Low: This controls the overall amount of bass frequencies (100 Hz). This control allows
+/- 15dB of boost or cut.
(10) Master Middle: This controls the overall amount of middle frequencies (1K Hz). This control
allows +/- 15dB of boost or cut.
(11) Master High: This controls the overall amount of high frequencies (10K Hz). This control allows
+/- 15dB of boost or cut.
(12) Main Output: A 1/4 2 conductor line output. The impedance is 1K ohm. @ -10dbv. It is used to
allow the combined signals of the entire mix to be sent out to additional amplifier (for more overall
power or to create a mirror image for a monitor amp), or for patching in external equalizers or effects
such as delays or digital processors.

(1) Power: This switches the unit on or off. When the unit is powered up, a red LED will come on also.
(2) Power Socket: The socket for connecting external power source.
(3) External Output: These are 2 conductor 1/4 speaker outputs. You may connect 1-8
ohm speaker cabinets. Do not go below rated minimum impedance.
(4) Tape Play (L/R): These RAC jacks are for brining in a tape deck, CD player or other line level
source. The impedance is 10K ohms @ -10 dBv.
(5) Tape Record (L/R): These RC jacks are for hooking up a tape deck to record from the mixer. Both
channels are summed into mono for compatibility. The signals are taken pre-master section, meaning
that they are without reverb or the master tone section, and does not include the Tape In signal. The
impedance is 1K ohms @ -10 dBv.
