I work for an estate sale. This item although connected to the home theater equipment was seldom, if ever used.
Two-channel, solid-state power amplifier with Sustained Plateau Biasing output stages. Power output: 600Wpc into 8 ohms (27.8dBW), 1200W into 4 ohms (27.8dBW). Power bandwidth (-3dB): 4Hz-20kHz. Output impedance: 0.03 ohms. Input sensitivity: 4.3V RMS (balanced) for rated output. Input impedance: 85k ohms
After the useful tip from this community the estate has adjusted the price to hopefully suit one more current
