Features include a
stereo beacon, combination FM center-channel and AM signal strength tuning
meter, left and right output power meters calibrated from 0,01 to 100 watts
into 8 ohms and -40 dB to +3 dB with 0 dB representing 50 watts, wide and
narrow FM IF bandwidth selector, an Fless than mute automatically applied in
the auto stereo mode 9mute is always off in the mono mode), and an output
hold-off that prevents power supply turn-on transients from being fed to the
speakers.
There are inputs for
magnetic phono and two tape. Outputs for two speaker systems, two tape, and
phones.
Controls are
provided for tuning, volume, balance, ganged bass, ganged treble, input
selection, and speaker selection. There are switches for loudness compensation,
hi-filter, tape monitor A, and tape monitor B.
The FM antenna
inputs is 75 Ω/300 Ω. A rod antenna and external connection are provided for
Am. Switched and unswitched AC outlets are provided.
Performance
FM Tuner - full
limiting was attained with 1,6 µV. The monophonic high fidelity sensitivity (60
dB quieting) measured 7 µV. The stereo high fidelity sensitivity (55 dB
quieting) was 55 µV. Full mute release was attained with 1,6 µV
At standard test
level the stereo frequency response measured +0,1 dB / -1,5 dB from 30 to
15,000 Hz. With the receiver set for wide selectivity the distortion measured
0,15% T.H.D. for mono 0,6% T.H.D. for stereo. With narrow selectivity the
distortion measured 0,11% T.H.D. for
mono, and 0,4% T.H.D. for stereo. The signal to noise ratio was 69 dB. Stereo
separation measured 40 dB. Selectivity was fair (wide) to very good (narrow)
AM Tuner -
distortion was a little higher than average
Amplifier - the
power output at the clipping level with both channels driven 20 to 20,000 Hz
into 8 Ω measured 43 watts RMS per channel. The Frequency Response at 43
watts/8 Ω was +0 dB/-0,2 dB from 20 to 20,000 Hz at a distortion no higher than
0,035% T.H.D. at any frequency
The tone control
range measured +11 dB / -9 dB at 50 Hzl
+9 dB/-8 dB at 10,000 Hz
The magnetic input
hum and noise measured -62 dB; stereo separation was into the noise level.
Within the power
capabilities of the amplifier the power meters were within 10% accuracy at
their calibrated values. Frequency Response was essentially "flat"
from 20 Hz to 20,000 Hz
