CHIME
When the contact is closed, if the CHIME dipswitch (13) of the channel is in the ON position, an
attention tone will be played by the loudspeaker system.
SILENCING THE INPUTS
When the contact is closed, the AUX input and the other inputs 1-4 that have the respective VOX
PRIORITY dipswitch (14) in the OFF position are silenced. The inputs will remain muted as long as the
clean contact remains closed.
Note: it is advisable to always use microphone bases with TALK button and clean contact, for better
management of the silencing of inputs.
Note: the clean contact will not silence the inputs that have the VOX function activated (ON). For
details on the VOX function, see point 14
WARNING
It is recommended that you set the input level to the minimum before changing the position of the input
selector, to avoid unwanted noises.
Some line level devices do not support "PH" phantom power, which could therefore cause permanent
damage to them, so it is not recommended to activate it when a line device is connected to the input.

AUX IN A / B
These are two RCA female connectors that accept two RCA plug from LEFT and RIGHT channels of a line
level stereo source (e.g. radio tuners, television receivers, media players, etc.). Each RCA input is wired
as follows:
Tip = + positive or "hot"
Sleeve = shield or ground
By means of these inputs is possible to use an external source instead the media player inside the
amplifier, selecting it with the front panel switches (10) and adjusting the volume with the AUX LEVEL
potentiometer (9).
19
PRE OUT – AMP IN
These are two RCA female connectors that accept two RCA plug. As standard, the AMP IN input is
connected to the PRE OUT output with a jumper.
It is possible to optimize the signal to be amplified by inserting between the two terminals an external
processing unit, typically a graphic equalizer, to optimize the spoken words intelligibility. For the
connection refer to the figure.
