- Using the microswitches 1 to 4, you can select the zone to which the input channel signal will be sent.
Place the corresponding microswitch in the ON position to send that input signal to the desired zone.
For example, if you want input channel 3 to be heard in zones 1 and 2, microswitches 1 and 2 of INPUT
3 must be set in the ON position. If you want the USB/SD/MP3 player with digital FM tuner to be heard in
zones 1 and 4, the microswitches 1 and 4 of the USB/SD/MP3/FM module must be set in the ON position
INPUT PRIORITY
- The priority function automatically reduces the level of the inputs with lower priority so that the message
broadcast by those of higher priority can be clearly heard.
- In this case, the input with maximum priority is the dynamic microphone input INPUT 1 and it is activated
by signal level. To activate the priority function, the PRIORITY ON/OFF button located on the front panel
of the device should be pressed.

CONNECTION
- Make the connections with the amplifier and PA power amplifi er of the system switched off and
disconnected from the power supply.
- Connect the audio devices or microphones desired to the corresponding inputs. If a dynamic microphone
is connected to inputs 2 or 3, set the sensitivity adjustment control GAIN close to its minimum. If a
condenser microphone is connected to inputs 2 or 3, also place this control in the same position and
activate the P48V selector.
