The PA-S 2200 is a sophisticated 2-Channel amplifier for use in AV systems, multi-room systems and multi-channel PA systems. The circuit design of the PA-S 2200 combines superior sound quality and operational reliability with minimal power consumption. The processor-controlled class-D amplifiers guarantee outstanding efficiency levels and high power reserves. The Auto On/Off function automatically switches the amplifier to energy-saving SLEEP mode if no input signal is detected. The amplifier has an output rating of 2 x 200 watts at 2 – 4 ohms or 2 x 120 watts at 8 ohms. It is equipped with both cinch inputs and symmetrical inputs. A ground lift switch and DIP switches for changing input sensitivity enable optimum adaption to different signal sources. The front features LEDs for Standby/Power, Sleep, Signal, Limit and Protect. The inputs, volume controllers for each channel, ON/OFF contact and VCA inputs for volume control are all located on the back. The external volume can be controlled via a control voltage of 0 – 10 V, via the WP-V and RP-V volume control panels, or via the DV module and Up/Down contacts.
