Page 3: Installation
3 installation the radio systems distribution amplifier combines solid state electronics and functional flexibility in one small package. Two high quality audio op amps provide balanced output and individual gain adjustments of each channel. Excellent isolation is provided between outputs. Each bala...
Page 4: Operation
4 operation controls consist of individual channel gain adjustments. Nominal operating levels are 0 dbm input and +10 dbm output. Higher operating levels can cut dynamic range by operating too close to the clipping point. Adjust each output to the desired level, keeping clipping in mind. The input s...
Page 5: Circuit Description
5 circuit description power supply: a large circuit board mounted transformer and two, three terminal regulators provide dc power. In the da- 16, one supply is used to power both circuit boards. Input stage: a high speed op amp, 5534, is used as a differential pre-amp. This unit exhibits low noise a...

10 using active balanced circuitry balanced lines have been used for many years and are in continued use today because of their immunity to stray pickup. Induced signals appear on both sides of the balanced line. The receiving end of the balanced line responds only to the difference voltage between ...
