The PA71 mixes an XLR microphone signal with stereo (mixed to mono) RCA signals. The combined signal is sent to spring loaded output terminals via a seven watt power amplifier. The unit also features a 1/4" Line/Powered output. The XLR input features switchable 12VDC phantom power. This unit is ideal for small room applications where a simple mix of a microphone with a cassette or cd player is needed.
