The PRC-970 was designed for the studio and TV

transmitter applications. The front panel provides

primary controls for Video Gain, Chroma Gain,

Pedestal Level, and White Clip. For each of these

controls, an LED shows the CAL position which

overrides the internal presets. Other controls on

the front panel include Video By-Pass, Field One

and Field Two Pass/Delete, AGC On/Off, Black

Clip, Sync Gain, Burst Gain, Subcarrier Coarse

Phase, Subcarrier Fine Phase, and Horizontal

Phase, A connector on the rear panel provides

remote control of Video Gain, Chroma Gain,

PedestalLevel,WhiteClip,BurstGain,SyncGain,

and Black Clip.

TheremotecontrolismodelPSR-970.Theremote

can be located up to 250 feet away from the main

unit.

A new approach to video AGC is incorporated into

the video and chroma level circuitry called “Dual

Slope Release”. The DSR constantly monitors

sync tip, peak whites and chroma level and can

keepeachparameterwithinNTSCspecifiedlimits.

Front panel LED’s indicate when any of the AGC

circuits are in operation, alerting the engineer to

the fact that the incoming video needs to be

corrected. A front panel switch can defeat any or

all AGC’s if so desired. Front panel LED’s show

the presence of Input Video, Auxiliary, and

Reference.

Anotherfeaturethatisimportantfortransmittersite

operation is the video detect/auxiliary select

function, If the primary video feed is lost, the PRC-

970 automatically checks for an auxiliary input. If

no AUX signal is present, the PRC-970 will output

a black burst signal of its own, generated within. A

relay provides a Hard-By-Pass in case of AC

power failure. In addition, By-Pass mode can be

selected from the front panel or by remote control.

A switch on the rear panel selects between

differential input and non-differential. An external

reference input is provided for the production

studio who wishes to process the output of the

switcher.

All of these features are packed into a one rack

unit case. The unit is engineered to exacting

standards of performance and reliability.
