| Power output |
210 watts per channel
continuous from 20Hz to 20kHz. 1kHz total harmonic
distortion typically 0.5% at 210 watts, below .02% at 1
watt. Approximate actual power available at "clipping" 240
watts (1kHz). |
| Frequency response |
(-3dB points at 1
watt) 0.5Hz to 240 kHz. |
| Input sensitivity |
1.7V RMS Balanced for
rated output. (27 dB gain into 8 ohms.) |
| Input impedance |
200K ohms Balanced |
| Output taps |
4, 8 and 16 ohms |
| Output regulation |
Approximately 0.6dB
ohm load to open circuit |
| Damping factor |
Approximately 14 |
| Hum & noise |
Less than 0.3mV RMS -
106dB below rated output (IHF-A weighted, input shorted, 16
ohm output) |
| Power supply energy
storage |
Approximately 787
joules. |
| Power requirements |
105-130VAC 60Hz
(260-250VAC 50Hz) 680 watts at rated output, 950 watts
maximum, 380 watts at "idle", .15 watts off. |
| Tube complement |
