SERIAL #

R1 – RF OUTPUT Connector

This is the converted channel output.

R2 – COMPOSITE IF IN Connector

This is the composite IF input to the output channel

circuits. The composite IF has both the aural and

visual IF combined. This connection is normally

cabled directly to the "COMPOSITE IF OUT"

connector (see Item R3). This external IF loop allows

the use of accessories such as scramblers or

alternate video sources. Note that accessory

equipment must also have the visual carrier at

45.75 MHz and the aural carrier at 41.25 MHz. Both

input carriers must be at their nominally specified

levels.

R3 – COMPOSITE IF OUT Connector

This is the composite IF output from the IF circuits.

The composite IF provides a vestigial sideband

filtered visual carrier at 45.75 MHz (plus or minus

any input signal offset) combined with a level

controlled aural carrier at 41.25 MHz (plus or minus

any input signal offset). This connection is normally

cabled directly to the "COMPOSITE IF IN" connector

(see Item R2).

R4 – RF INPUT Connector

This is the input to the channel processor circuits for

all signals with video carrier frequencies in the range

of 54 through 806 MHz.

R5 – FUSE Holder

Always replace this fuse with one of the same type

and rating:

1/2 Amp, 250 V, SLO-BLO, 5 x 20 mm type.

R6 – LINE CORD

This is a three-wire power cable. When the cable is

connected to a properly wired AC power line outlet,

this cable grounds the instrument cabinet. Connect

to a nominal 115 VAC ±10%, 60 Hz source. Do not

defeat the safety purpose of the attached line

cord plug.
