(8) LOW EQ Control (BASS)
Active equalization control that adjusts the low frequency response. Clockwise rotation boosts lows while counterclockwise
rotation provides a cut (reduction) of the low frequencies (±10dB).
(9) RCA AUX IN
Accepts signals from other sources, such as another mixer or background music source. Signal level at this input is controlled
by the AUX level control and is fed to the Master output.
(10) Input 1MIC/LINE Switch
Sets the gain of Input 1 for mic or line level sources.
(11) Input 1
Low Z mic/line level balanced input is provided via screw terminals.
(12) Input 2
Screw terminal AUX inputs are summed with the AUX RCA jacks (9).
(13) Outputs
A direct output, as well as several transformer outputs, are provided to allow the proper interface between the amplifier and
the speaker system. The direct output allows direct connection to a 4 ohm speaker system. Connect the speaker (or speakers)
from the 4 Ohm “+” terminal to the 4 Ohm “-” terminal. The direct output is a bridged output and should not be grounded.
70V and 100 V outputs are also provided for “constant voltage” speaker distribution systems. The 70 V and 100 V output
connection is between the COM terminal and the 70 V or 100 V terminal.
