Page 3: Installation
MOUNTING: The DA-8 and DA-16 each occupy only 1-3/4 inch of height in a 19 inch rack. To allow for adequate ventilation, avoid mounting the unit directly above large heat producing equipment such as power amps or power supplies. -
Page 4: Operation
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 stage has a built-in 6 dB pad. -
Page 5: Circuit Description
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 and high output drive capabilities. -

Page 10: Using Active Balanced Circuitry
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 the lines which is the desired signal. -
