| Processor-controlled
system amplifier PPA-120/180
Processor-controlled system amplifier, 120 W/100V, with
6 programmable inputs and built in FM-tuner.
The inputs can be activated with the front keys or via external contacts. The processor
technology permits individual configuration of each input via the front keys. These can be
for example be mixed or switched with different priorities; gong signal prior to call,
control override. The input sensitivity can be set to either line or microphone level. 3
loudspeaker circuits are adjustable. Spare 2 RPU can be retrofitted with gong SM-13E,
equalizer EQ-15-VQ, paging stand module IM-20, balanced transformer and emergency power
interface, can be converted to 19"
