7 SPECIFICATIONS
Discriminator and Sub-Audio Level:

7.4.16 Audio Distortion

With 750uSec. De-Emphasis: Less than 3% at 1KHz and 60% of rated system
With Flat Response: Less than 5% at 1KHz and 60% of rated system deviation.

7.4.17 Channel Select Input/Output

Coding: 8 Lines BCD coded 00-99
Logic Input Levels: 0=<0.4Volts
Internal 10K pull down resistors selects Ch.00 when all inputs are O/C.

7.4.20 Carrier Operated Switch Output

Floating Opto-Coupler Output: The carrier operated switch output is via an opto-coupler.
Collector and emitter connections are available to allow connection for source or sink.
The opto-coupler can be linked inside the receiver to be on when a carrier is detected or to be
on in the absence of carrier.
Connection to Remote Switch via 600? Line: Internal connections are provided so that the
opto-coupler can be connected to the 600? line for use over a single pair.
Current Source/Sink, Collector Voltage: Ic = 10mA Maximum
