1783 Line Output Module

 

 

<< Previous

The mixer also contains two auxiliary input channels for high-impedance line or tape sources. These channels have independent monitor sends, pan pots, and slide faders.

DESCRIPTION


Output Module. The ALTEC LANSING 1783 line output module provides the drive capability necessary to interface with other professional equipment. The electronically balanced output stage provides a low source impedance to drive subsequent stages. If transformerisolation is necessary, the module's circuit board accommodates the optional PC-mount 1786 output isolation transformer. The continuously variable output level control is local to the module permitting independent adjustment of each line output.
