RIGHT CHANNEL - OUTPUT Terminal 15 High
(Z = 600 2) Terminal 16 Low
Terminal 17 Ground (chassis)
Any standard VU-Meter can be used as a Remote Meter if the internal
rectifier is removed. A variable resistor of approximately 10K should
be used in connection with the Remote Meter. This variable resistor
(Ohmite CLU-1031) enables the zero of the Remote Meter to coincide
with zero on the meter in the unit (see "REMOTE METER CONTROL"
illustration).
If desired, Fairchild Recording Equipment Corporation can supply such
Remote Meter (order Fairchild Part No. A-2329)).
