Operation

Front Panel Controls & Indicators

Input Volume Controls

Each input module may be individually controlled by its corresponding volume control knob.

Signal / Clip Indicator

A single LED located above each channel’s volume control indicates the audio activity of that channel’s input. Green indicates signal is being applied to the mix bus. Red indicates that the input signal coming from the input module into the amp is clipping and distorted.This is caused by either an input signal that is too high or an input module volume control (gain) that is set too high.

Bass and Treble Controls

The treble control has a cut/boost range of +/- 10 dB at frequencies above 10 kHz and provides a roll off after 20 kHz to reduce gain above the audio range.

The bass control has a cut/boost range of +/- 10 dB at frequencies below 100 Hz.When driving speakers using the direct-coupled output terminals, the bass filter’s response is constant to 20 Hz.When driving speakers using the trans- former-coupled output terminals, the amplifier automatically changes the bass filter’s response to a bandpass shape to reduce the level of bass frequencies below 40 Hz.This filter shape helps to avoid overdriving the speaker’s coupling transformer with low frequency signals that may cause noticeable distortion due to magnetic saturation of the transformer’s core.

Master Volume Control

The overall volume level of the amplifier is set by a Master Volume control. The Master Volume control is motorized and can be controlled by manually adjusting the knob or by a remotely-mounted control station. Connections and requirements for the remote control station (optional accessory) are described in the Connections section, under Remote Volume Control.

Average / Peak Switch & LED Output Meter

The LED Output Meter is an 11-segment meter that registers either the average or the peak level of the amplifier’s output signal. A red indicator is provided at the +3 dB level to indicate amplifier clipping. Amber indictors at the 0 dB and -3 dB levels indicate high amplifier output levels. The remaining 8 indicators (green) provide an indication of the output signal’s dynamics.The meter can be set to read either the average output signal level or the peak output signal levels by using the Average / Peak Switch to the left of the meter. In is average; out is peak.

Power Switch / Power Indicator

The AC power to the amplifier is controlled by the Power rocker switch, which illuminates when power is applied.
