Lowpass Filter Slope Selection Switch

This switch sets the lowpass filter's per octave attenuation for either 6dB or 12dB.

Peak Indicator LED

The peak indicator LED lights when either the input or the output level reaches 3 dB below clipping.

Input Level Control

This control adjusts the input gain by ±12dB to allow the use of a wide range of input sources. To insure the best S/N ratio possible, adjust this control so that the peak LED flashes only occasionally.

Lowpass Filter Control

This is a shelving-type filter that provides a 12dB or 6dB per octave roll off above 2.5kHz and up to 30kHz. Its main purpose is to stop high frequency noise, oscillation, and certain types of RF interference from damaging tweeters. It is also useful in reducing excessive background noise, such as that produced by old phonograph records.

Equalizer Sliders

These sliders are adjusted to tune or equalized the overall frequency response of a sound system.

Equalizer Indicator LED

The indicator LED turns on whenever the equalizer IN/OUT switch is "in".

Equalizer IN/OUT Switch

Equalizer switch puts the input signals either in circuit or out of circuit of the equalizer. The "out"

position provides flat audio response no matter what the positions of the equalizer sliders and the filter (LPF/HPF) control.

Security Cover Mounting Hole

This hole is used to mount the supplied security cover with two screws to avoid accidental changes in set position of control knobs and switches.

Power Switch

Pushbutton alternately switches the AC power on and off.

Power Indicator LED

The green LED lights when the power switch is "on".

Highpass Filter Control

This shelving-type filter provides an 12dB per octave rolloff between 300Hz and 15Hz. It is especially useful for reducing stage or turntable rumble, AC hum, wind noise, and other subsonic components that waste amplifier power and tax speakers.

Filter Indicator LED

The filter indicator LED lights when the filter switch is "in".

Filter IN/OUT Switch

Pressing this switch while equalizer indicator lights provides the frequency response set for by the lowpass- and highpass-filter control. Press the switch again to disable the lowpass- and highpass- filter control.
