Your CVA100-2 amplier has 2 high-pass lters, one for each channel.

The high-pass lter is used to attenuate (reduce the volume of) fre-

quencies below a desired cutoff point. The high-pass lters on the

CVA100-2 have 3 cutoff points which can be selected: 65Hz, 85Hz,

150Hz. To make a selection, slide the switch to the desired cutoff

point.

The purpose of this high-pass lter is to both prevent unwanted noise

that can come in with the signal sources as well as to prevent damage

to speakers which are unable to handle frequencies which are more

suited for a subwoofer.

3.2.3 Remote Volume Control

CVA 100-2 ampliers can have their volume remotely controlled (or

muted) via the Euro Block input on the rear of the amplier. Remote

muting is also useful for re-alarm situations in which all unnecessary

sound must be silenced.

NOTE: If the remote volume control connector is utilized,

it will override the volume knob on the rear of the unit.

In order to remotely control the volume of the unit, a 10k-ohm potenti-

ometer should be placed between the +10V pin and the GND (Ground)

pin on the rear of the unit with its wiper on the RVC pin. The volume

will be determined by the selected resistance on the potentiometer,

the greater the resistance the louder the volume.

The amplier can be remotely muted by making a connection between

the GND pin and the MUTE pin. No power should be applied to these

pins, simply a contact connection.
