MOS Super Optical Class-A Stereo Power Amplifier POA-3000RG

The POA-3000RG (Reference Gold) is a stereo hi-fi power amplifier with power output of 250 Watts RMS per channel into 8 ohms. Stereo or mono operation. Left and right peak output level VU meters. Normal or Balanced inputs. Outputs for two pairs of loudspeakers.

Specification
Rated output power Stereo:   Continuous 250W per channel min. both channels driven                                                        into 8Ω from 20 Hz to 20 kHz with no more than 0.05% THD
                                              400 W + 400 W (4Ω load, THD 0.1%)
Rated output power Mono:     Continuous 500 W min. monaural channel driven, into 8Ω
                                                from 20 Hz to 20 kHz with no more than 0.05% THD.  
                                              800 W (4Ω load, T.H.D.: 0.1%)
Dynamic power Stereo:          900 W + 900 W (2Ω load)
                                             1200 W + 1200 W (1Ω load)
Dynamic power Mono:          1500 W (2Ω load)
                                             1600 W (1Ω load)
THD Stereo:                          0.005% (20 Hz - 20 kHz, 8Ω load, rated output -3 dB)
THD Mono:                            0.008% (20 Hz - 20 kHz, 8Ω load, rated output -3 dB)
Intermodulation distortion:     0.003% or less (7 kHz/60 Hz  = 1/4, 8Ω load,                                                 at an amplitude output equivalent to the rated output)
Power bandwidth:                  5Hz - 50 kHz (T.H.D.: 0.05%, 8Ω load, rated output -3 dB)
Frequency response stereo: 1 Hz - 100 kHz (8Ω load, at 1 W output)
S/N ratio stereo:                     NORMAL    ... 121 dB
 ("A' curve weighting):            BALANCED ... 112 dB
S/N ratio mono:                      NORMAL    ... 108 dB
                                              BALANCED ...121 dB
Speaker output terminals:     A or B: 4Ω or greater
                                              A + B:  8Ω or greater

Level Meters
Indication method:                Peak value indication output level meter
Indication range:                 -50 dB to +5 dB
                                            0dB = 200 W/8Ω (STEREO setting)
                                            (Twice the watt indication value at the MONAURAL setting)
Frequency response:          10 Hz - 100 kHz  (at 1 W output)
