ROWEN PA4 4-channel power amplifier

The 4 output stages of the Rowen PA4 correspond to those of the PA2 and can ideally be used for Bi-Amping, Bi-Active or as an optimal solutionfor the extension to surround speakers. In the "symmetries operation" the PA4 delivers out of its small housing 2 × 140W continuous rating at 8 Ohms (2 × 900W peak music power output at 1 Ohm). In the "normal operation" mode there are 4 × 55W continuous rating and 4 × 600W peak music power output available. It has a supply exit for the PR2 preamp and its 4 power amps have negative output impedance.
