DESCRIPTION
The UP 8500 amplifier series includes 3 similar models having different channel number
and maximum output power per channel:
- UP 8501 1 channel, max. power: 500 W
- UP 8502 2 channels, max. power: 250 W per channel
- UP 8504 4 channels, max. power: 125 W per channel.
Each channel has 3 audio inputs (all ‘line’ level):
- INPUT 1 ‘LINE’ balanced input (for signals coming from preamplifiers, active
paging microphones, message players, etc.).
- INPUT 2 ‘LINE’ balanced input (for signals coming from preamplifiers, active
paging microphones). It can be used for unbalanced stereo signals
(from CD – MP3 players, tuners, etc.).
- IN TEST Unbalanced input for channel test signals.
The INPUT 1 can get the priority (by a command) over the INPUT 2, which is disabled
when the priority is in progress.
The TEST IN input allows to use a test signal to verify the proper channel operation.
The TEST IN input can get the priority (by a command) over both INPUT 1 and INPUT 2,
which are disabled when the priority is in progress.
Channel outputs are 70 V – 100 V constant voltage lines (for loudspeakers having
matching transformers).
In addition to the connection to the mains, the amplifier can also be powered by batteries
(voltage: 48 V dc), in order to ensure its proper operation even when the mains supply is
temporarily unavailable.
Front panel LEDs indicate the device state (on – stand-by), power supplies, protections
and audio signal levels.
Fix each amplifier on the 19” rack cabinet front side through 4 screws.
UP 8500 series amplifiers have forced ventilation controlled by a thermostat and can be
stacked without spaces or ventilation panels.
Air ventilation is horizontally, so it is necessary to keep open the lateral sides.
