The Role of Insert Jacks

Time and again it is necessary to insert additional units like equalizers into a signal way. This

is not a problem with systems set up separately with individual mixers and power amplifiers.

In this case, the signal cables are simply connected to the units. This is different with compact

full amplifiers, as they are customary for PA applications. In this case, the separation is done

by special jacks. With these combined jacks, it is possible to separate the preamplifier with the

inputs (PRE OUT) from the mere power amplifier (AMP IN). The illustration shows the outputs

by example of the

PA-1120

amplifier. Due to the ability to separate, it is now possible to insert

additional units into the signal way.

Two examples of such additional units and their features are shown below.

Automatic Volume Control with PA-100ANC

By using this ambient noise controller, it is possible to achieve a signal

volume depending on the ambient noise. To put it more simple, the

louder the surrounding, the more signal is fed to the speakers.

In practical application it is possible, e.g. to match the volume of the

background music in a restaurant automatically to the noise level of

the rooms. This adjustment is usually slightly delayed and attenuated,

so that short noise peaks will not have any effect on the volume con-

trol.

A microphone is additionally required for the

PA-100ANC

Remote Volume Control with VCA-202

The remote volume control is a further requirement which often has to

be met. This is always the case, if the system is not set up at a location

where staff may be nearby. For this purpose, previous solutions includ-

ed the adjustment of the speaker outputs. With the

VCA-202

and

VCA-202RN

, the amplifier output power can now easily be adjusted

remotely. The

VCA-202

is also inserted between preamplifier and

power amplifier. This could be a compact PA amplifier, a mixer with

separate power amplifier or also a CD player and a power amplifier.

A basic cable with a minimum of 3 wires connects the control unit and

the

VCA-202

. Because this cable does not carry an AF signal, shield-

ing is not compulsory. If both inputs of the

VCA-202

are used, the vol-

ume adjustments can either be done together via one control or sepa-

rately via two controls.
