PRAESENSA *Amplifier, 600W 4-channel | PRA-AD604 | en 73
Bosch Security Systems B.V. Installation manual 2019.11 | V1.00 |
Caution!
For compliance to UL62368‑1 all loudspeaker wiring must be Class2 (CL2); this requirement
does not apply for compliancy to EN/IEC62368‑1.
Caution!
Amplifier outputs may carry output voltages up to 100VRMS. Touching uninsulated terminals
or wiring may result in an unpleasant sensation.
Notice!
Only amplifier channel1 and the spare channel are capable of delivering up to 600W
maximum. All other channels are limited to 300W maximum. In practice this does not impose
any limitation on the flexibility of partitioning the total amplifier power across the channels,
because if there is one zone with more than 300W load, which is connected to channel1, no
other channel can be loaded with more than 300W anymore without exceeding the total
maximum of 600W.
