LEVEL

1.MASTER VOLUME: The MASTER VOLUME control is used to set the overall level of the audio going to the speaker(s). Each individual input has its own level control, and all of these input signals are combined (mixed) into one signal that flows through the MASTER VOLUME control.

2.LIMIT: The LIMIT LED lights up to indicate when the limiter is active. The limiter helps to prevent distortion which can cause damage to the speaker system. The level of the signals coming from the inputs (microphones, CD player, LINE IN) is ‘watched’ by the limiter circuit. The limiter instantly reduces the signal to a safe level if it becomes too large. When the limiter light is on, the power amplifier has reached maximum power.

3.VOICE OVER MUSIC: This is a special feature that automatically reduces the level of the LINE/CD inputs whenever sounds are produced at any of the four microphone inputs (WIRELESS MIC 1, WIRELESS MIC 2, MIC 1 IN, and MIC 2 IN). After a few seconds of silence on the microphones, the LINE/CD signal will slowly return to its original volume level. This is handy for events that require background music with occasional announcements.

The VOICE OVER MUSIC control sets the amount of reduction in level that occurs when the circuit is triggered by a micro- phone signal. For less reduction of the LINE/CD signal, turn the VOICE OVER MUSIC control clockwise. To disable VOICE OVER MUSIC, turn the control fully clockwise.

4.TONE CONTROLS: The LOW and HIGH controls provide the ability to cut or boost the corresponding frequencies in the LINE/CD signal. These controls do not affect the microphone signals.
