INPUT SECTION FEATURES:
MASTER SECTION:
(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.
(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
/- 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.
(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.
(5) Reverb Control:
This is a send control to the reverb buss. It controls the amount of reverberation
added to the input signals.
(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.
BACK PANEL:
(1) AC Cable:
This is standard cable for use with standard 120 volts current. It is grounded and should
NEVER have the ground pin removed for any reason.
(14) Aux Input:
A 1/4 2 conductor line level output. output from the effects buss. This jack is used
primarily to connect to and external effects device such as a chorus, delay, or echo.
(13) Reverb Output:
A 1/4 2 conductor line output. It is used to allow the processed signals controlled
by Reverb volume to be sent out to additional amplifier (for more overall power or to create a mirror
image for a monitor amp.)
(15) Reverb Footswitch:
A 1/4 2 conductor foot switch jack. It is used to plug in a push on push offtype
footswitch to turn the internal reverb buss on or off.
(16) Power:
This switches the unit on or off. When the unit is powered up, a red LED will come on also.
(2) Speaker Output:
These are 2 conductor 1/4 speaker outputs. Each one is rated at 8 ohm minimum
impedance. Total minimum load for the amplifier is 4 ohms. You may connect either 1-4 ohm, 1-8 ohm
or 2-8 ohm speaker cabinets. Do not go below rated minimum impedance.
(3) 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.
(4) Tape Record (L/R):
These RAC 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.
