0.05% from 250 mW to rated power at 8Q
with any 2 mixed frequencies between 10 Hz
and 30 kHz at 4/1 voltage ratio
10 Hz to 70 kHz ( + 0 dB, -0.5 dB)
93 dB (Unweighted)
103 dB (IHF-A weighted)
5 Hz-50 kHz
1.5 M seconds rise and fall time
unconditionaly stable with any type of load
or no load including fullrange electrostatic
loudspeakers
150 min. (8Q 20 Hz to 20 kHz)
75 min. (452 20 Hz to 20 kHz)
0.8 volts
for rated output at 8Q
10 KQ
75 Tr. 60 D. 1 1C (for model 600)
67 Tr. 60 D. 1 1C (for model 300)
1. Low impedance electronic-sensing circuit
limits with output current below 2Q
without limiting with 4Q or higher (or
reactive loads)
2. Thermal sensing of inadequate ventilation
Relay circuit protects loudspeakers from low
frequency oscilations and plus or minus DC
output. Five seconds turn on delay eliminates
transient disturbances.
