Before powering up, make sure that all the connections have been made correctly and
the voltage of your mains corresponds to the voltage shown on the rating plate on the
unit.
The voltage selector and the fuse are inside the amplifier.
Refer to the respective manual section.
i
Input for the secondary 48 V dc power supply (batteries) necessary to ensure the
amplifier operation even if the mains supply is temporarily unavailable.
Make sure the connection polarity + / – is correct and use a cable having wires with a
suitable section (suggested: 4 mm²) for the max. current (15 A).
Connect all loudspeaker respecting the phase.
Every loudspeaker shall have a matching transformer, which input is suitable for the line
voltage (70 / 100 V).
Make sure loudspeaker lines are not shorted before turning the amplifier on.
Check periodically for possible ground leakage on loudspeaker lines to avoid amplifier
failure.
If necessary, intervene to re-establish line insulation.
UP 8501
After setting the amplifier output voltage through the 70V – 100V 14 dip-
switch, connect the positive wire of the loudspeaker line to the amplifier
output
13 ‘a’ contact and the negative wire to the ‘b’ contact.
The total power of all connected loudspeakers shall not exceed the amplifier
nominal power (500 W).
UP 8502
This model has 2 independent outputs (2 channels): AMP A 13a
and AMP B 13b .
Set the voltage of both outputs through the
A 70V – 100V (AMP A) and
B 70V – 100V (AMP B) 14 dip-switches before connecting the
loudspeaker lines.
The total power of all connected loudspeakers of a single channel (considering only 1 of
the 2 available outputs) shall not exceed 250 W.
See the UP 8501 model for loudspeaker connection.
UP 8504
This model has 4 independent outputs (4 channels):
AMP A 13a , AMP B 13b , AMP C 13c and AMP D 13d .
Set the voltage of the 4 outputs through the A 70V – 100V (AMP A), B 70V – 100V
(AMP B), C 70V – 100V (AMP C), D 70V – 100V (AMP D) 14 dip-switches before
connecting the loudspeaker lines.
The total power of all connected loudspeakers of a single channel (considering only 1 of
the 4 available outputs) shall not exceed 125 W.
See the UP 8501 model for loudspeaker connection.
