The Atlona AT-PA100-G2 is a compact power amplifier designed for low impedance applications. A mode selector switch allows the PA100-G2 to deliver two channels of 20 watts each into 4 ohms, or a single, bridged channel of 40 watts at 8 ohms. This Class D amplifier is energy efficient and convection cooled. The PA100-G2 features a balanced mic/line level audio input with selectable 48 volt phantom power, as well as unbalanced stereo audio input through RCA or 3.5 mm connections. It can deliver stereo or mono output, and provides mixing for the balanced and unbalanced audio inputs, each with independent gain and mute control. In addition to the amplified speaker output, a line level audio output allows the incoming audio to be fed into an additional amplifier or audio system. The PA100-G2 is controllable via RS-232, or through IR with the optional AT-PA1-IR-G2 remote control kit
