An interesting feature of these models is that it is possible to control

the volume simply by means of remote push-buttons (similar to com-

mon electrical UP/DOWN push-buttons), enabling all sorts of possible

uses and making it easy to build them into systems.

It is also possible to switch on the amplifiers from a remote station

using a remote stand-by switch. A specific service output will enable

activation of a signal confirming that they have switched on.

These specifications, combined with the possibility of powering the

amplifier from a source ranging from 12 to 24 VDC, ensure excellent

flexibility and versatility of installation.

OPERATING MODES

The unique feature of these amplifiers is that they can be used in three

different modes, depending on requirements:

STEREO

. Amplifier with two stereo channels (L + R)

BRIDGE

(mono). Amplifier with a single channel featuring a higher

output power (bridge connection). If a stereo source is connected

to them, the Left and Right inputs are mixed.

PA

(mono). Amplifier with two independent channels, the first

of which for background music and the second (priority) for

calls, by activation from an external contact. The typical sound-

broadcasting application for interrupting the background music, by

means of a control, when a handsfree call is received.
