4 Ohm: 2x 40 W (1kHz THD 1%)
Dynamic power
8 Ohm: n.a.
4 Ohm: n.a.
Total harmonic distortion: 0.05% (-3dB rated Output, 8 Ohm)
Attenuation factor: n.a.
Frequency response: 10 ... 40,000 Hz
Signal to noise ratio: 72 dB, 96 dB
Stereo channel separation: n.a.
Tone control:
Bass: 100 Hz ± 10 dB
Treble: 10 kHz ± 10 dB Loudness: no
High Filter: no
Low Filter (Subsonic): no

Direct/Line-Straight: no
Special Features
Balance control via double volume control on one axis
red LED signals that the unit is switched on
switch for tape monitor; tape playback is not provided via the source selector switch
switch for CD-Direct, bypasses only the source switch and the tape monitor switch, but in principle passes through the tone control,
Headphones switch off main speakers when plugged in; except U.K. model.
Model variants USA, Canada and Asia have additional power connections
Speaker clicks when switched off regardless of volume setting
Electronics
Amplifier
discrete push-pull output stage with bipolar transistor pair 2SC3853/2SA1489 (conceivable European replacement types: TIP3055/TIP2955, TIP140/TIP145 (Darlington))
Fuse protection of the power amplifiers per channel by F4.0A fine-wire fuse on the motherboard
Adjustment of quiescent current setting rudimentary possible, exact adjustment requires disassembly down to PCB solder side
uPC1225H driver module
phono stage with OP M521BP
Tone control in feedback path between output power stage and input driver stage
Headphones connected via series resistor to output stage
Power supply:
2x 27VAC nominal voltage (center tap) ; 2x 32VAC idle.
1x bridge rectifier (MB2U)
2x 8200uF filtering to ±36VDC -> supply output stage
2x linear longitudinal regulation to ±16,5VDC -> supply phono stage
protection of the power side by T1,0A fine-wire fuse inside the unit
Carefully insured shipped
