POWER OUTPUT:
105 RMS watts continuous per channel into 4, 8, or 16 ohms
both channels operating.
HARMONIC DISTORTION:
Less than 0.25% at 105 watts power output from 20 Hz to 20
kHz, both channels operating. Typical performance is less
than 0.1% at rated power. Distortion decreases as output
is reduced.
INTERMODULATION DISTORTION:
Less than 0.25% if instantaneous peak power output is 210
watts or less per channel with both channels operating for
any combination of frequencies 20 Hz to 20 kHz.
FREQUENCY RANGE:
20 Hz to 20 kHz +0, -0.1 dB at rated power.
15 Hz to 60 kHz +0, -0.5 dB at rated power.
10 Hz to 100 kHz +0, -3.0 dB at rated power.
NOISE AND HUM:
90 dB or more below rated output.
OUTPUT IMPEDANCE:
4, 8, and 16 ohms
OUTPUT VOLTAGES:
25 volts (connect to 8 ohm outputs.)
DAMPING FACTOR:
18 at 4 ohms output
13 at 3 ohms output
10 at 16 ohms output
INPUT IMPEDANCE:
200,000 ohms
INPUT SENSITIVITY:
0.5 volts. Level control provided for higher input voltage.
POWER REQUIREMENTS:
117 volts AC 50-60 Hz, 90 watts at zero signal output, 450
watts at rated output.
