19“ Power Amplifiers with 2 to 8 Channels

Our PA series of multi-channel power amplifi ers comprises sophisticated class D amplifi ers
designed for use in AV systems, multi-room systems and multi-channel public address systems.
They deliver outstanding sound quality with low levels of heat build-up and provide an Auto ON/OFF
circuit for each channel pair to minimize power consumption in the SLEEP MODE.
The amplifi ers are equipped with almost completely silent, temperature-controlled fans and a
selectable input sensitivity of +4 dBU or –6 dBU for home audio application.
Integrated limiters monitor voltage, current and power at the speaker outputs and thus prevent
distortion and overload. To enable remote control, the amplifi ers are equipped with an ON/OFF
contact and VCA inputs with separate channels for external volume control.
