ARCHITECT'S AND ENGINEER'S SPECIFICATIONS

The line output module shall have a low source impedence, continuous variable gain, and the capability for adding a 1786 output isolation transformer. In addition, the module shall be fully compatible with the 1700-series mixer/preamplifier and mixer/power amplifier mainframes, and accept any one of the 1790series input connectors.

The line output module shall meet the following performance criteria. Gain: 26 dB, continuously variable. Frequency response: 50 Hz to 20 kHz, ±1 dB. Output source impedance: <5052. Noise floor: <-80 dBm. Total Harmonic Disrtortion (THD): <.05%, (<.1% with 1786), Ref. 1 kHz, +8 dBm output, 30 kHz low pass filter.

The line output module shall be the ALTEC LANSING Model 1783.
