1. Bass Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) bass frequencies to a maximum of +6dB at 100Hz. Rotating
counter-clockwise from the 12:00 position will decrease (cut) bass frequencies to a maximum of -6dB at 100Hz.
2. Treble Control
Normally set at the 12:00 position, rotating clockwise will increase (boost) treble frequencies by +6dB at 10kHz. Rotating
counter-clockwise from the 12:00 position will decrease (cut) treble frequencies by -6dB at 10kHz.
3. Input 1
Balanced Microphone or Line level signals connect to the (+), (-), and (G) terminals. To select between Mic or Line input levels, refer
to the DIP switch chart on the rear of the amplifier for feature assignment. If connecting an unbalanced line level input, tie (short) the
(G) and (-) terminals together for negative or ground connection and the positive or (+) signal to the (+) terminal on the amplifier input.
If the input is used in Mic mode, Phantom power for condenser type microphones is available in the DIP switch settings on the rear
panel. Input 1 level control located on the front panel adjusts the levels to the amplifier mix.
4. Input 2
Input 2 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.
5. Input 3
Input 3 consists of RCA stereo summing inputs, suitable for connection to the output of CD/DVD players, etc.
6. Remote Mute Connector
Shorting the Remote Mute terminals will mute the inputs that are assigned to receive the mute command. When an input is set to
Mute Receive via the corresponding DIP switch, the input associated to the switch will be muted when terminals (G) and (M) are
shorted together. This connection is usually done via remote switch on a microphone.
