1703, University Sound 1-Watt Utility Amplifier with Hi-Z & Lo-Z Microphone Input (New Old Stock)
The University Sound 1700 Series are one watt solid state audio amplifiers suitable for a variety of low-power applications. The Model 1703 has both a Hi-Z unbalanced microphone input and a Lo-Z balanced microphone input. Each model has the same output configuration: an 8 Ohm, 1 Watt output for direct speaker connections and a 500 Ohm +4 dBm output for driving balanced phone lines. Both of the outputs can be loaded at the same time without mismatch on either line. The units have a single control to set the output level of the amplifier.
The model 1703 incorporates both a high pass filter and a low pass filter to contour the frequency response of the unit for maximum speech intelligibility. As supplied, the frequency response is -2 dB at 350 Hz and 7.5 kHz. Jumpers are provided on the circuit board which may be cut to exclude these filters.
All of the units are enclosed in a sturdy steel box with wall-mount flanges on two sides. Each is powered by a 120 VAC to 24 VDC power adaptor, included with the unit.
