It is possible to optimize the amplifier
signal setting an external unit ( so as un
equalizer processor, etc..) between the
two terminals .
For connections revert to the following fig.
9. 24 V DC POWER CONNECTORS
These two connectors allow the unit to be powered by direct current through an external power source such
as a generator or a 24 V DC battery.
If you opt for direct current powering, please insert a 20A fuse in the V DC supply line.
Note:
If continuous power is provided through a battery, be aware that the device cannot autonomously
recharge the battery.
10. Loudspeaker output line terminal
These Terminals are used for 4 Ω, 25 V, 70 V and 100 V loudspeakers connection
Connect the speaker lines to the COM terminal and to the desired Impedence/constant voltage terminal
(100V, 70V, 100V / 4
Ω). See paragraph 5.2
11. Loudspeaker ZONE output line terminal
Zone 1, 2, 3 and 4 (100V outputs ) output terminals
Connect the speaker lines to the COM terminal and 100V to the desired terminal ZONE
12. MOH OUTPUT 1W 8
Ω
Music On Hold Output. monitor output of the INPUT 5 signal.
This output allows you to connect a speaker (monitor), driven from the unit internal 1W amplifier, reproducing
AUX IN signal. Output signal is set by INPUT 5 volume control (fig.1 rif.4), or by rear panel MOH LEVEL.

MOH OUTPUT volume trimmer
14. MOH OUTPUT 600
Ω
Music On Hold Output is monitor output at 0dB of the INPUT 5 signal
15. TEL INPUT
Set to receive a high level telephone central audio signal (600 Ω ) ( balanced or unbalance) with priority on all
signals. The signal level is set through TEL trimmer. For priority regulation, read MUTE SEN (point 6)
16. TEL LEVEL
Telephone - paging volume trimmer
17. GND Screw
When there is no grounding on the power socket, such screw allows grounding connection of the mechanical
unit parts .
Attention.
Grounding Screw connection must be done by qualified person.
