This integrated amplifier has two sets of balanced XLR inputs, plus four sets of conventional unbalanced RCA line-level inputs (includes a phono input), A & B speaker outputs and a headphone jack that allow you to play music from a variety of audio sources. Featuring maximum configuration flexibility, it can be configured as a conventional stereo integrated amplifier, or set up with another PM-10 as a dual component four channel configuration for bi-amp operation, and it can also be paired with an AV pre-amp and used as a stereo power amplifier via the Power Amp Direct inputs.See all Integrated AmplifiersProduct Description
