Technik:

Minimum guaranteed power into 4 ohms or 70V/100V output: 80W maxi-
mum power at 1 kHz with 0.5% THD. Frequency Reponse (at 1 watt from
4-ohm tap): 70 Hz - 19 kHz +/– 1 dB. Frequency Response (at line out): 20
Hz to 20 kHz +/–1 dB. Power Bandwidth (at 4-ohm tap, 2 dB below maxium
1 kHz power): 50 Hz to 20 kHz with < 0.5% THD. Signal to Noise Ratio (ref.
to rated power, master volume at minimum): 85 dB. DC Output Offset:
< ±5 mV. THD: Less than 0.5% at rated power at 1 kHz. Input Sensitivity
(for full output at maximum gain): 800 mV. Input Impedance (nominal):
100 kilohms. Minimum Load Impedance: 100V output 160 ohms, 70V
output 80 ohms, 4-ohm output 4/8 ohms. Crosstalk: –70dB at 1kHz. Line
