PROGRAM MIXER (PGM-2000)

insert program audio (from a tape player, mixer, or stage mics) onto the intercom line.

INTERCOM LINE IN CONNECTOR
The 3-pin female XLR connector accepts the intercom signal from a PortaCom
PC-2000 Power Console. This is the standard input for the PGM-2000.

PROGRAM IN CONNECTOR
The 1/4" phone connector accepts the line-level output of a mixer, tape player,
etc. and inserts that music/program material onto the connected intercom
system.
INTERCOM OUT CONNECTOR
The 1/4" phone connector provides a line-level composite of the intercom
signal. Use this output to connect a recorder or a remote amplified speaker.
CHANNEL A/B SWITCH
Selects the channel (A or B) which the program material will be inserted in the
system. When using the NORMAL A / ISOLATED C output, no program material
will be on this output when the channel switch is set to "B" position.
NOTE: Program cannot be inserted on isolated channel C unless a second
PGM-2000 is used in the system configuration.
PROGRAM LEVEL SETTING ADJUSTMENT SCREW
Adjusts volume level of inserted program material as heard on the intercom
system. Turn clockwise to increase volume of the program material, counter-
clockwise for lower volume.
POWER LED
Indicator lights when power source is connected to PGM-2000.
(There is no power on/off switch - power is supplied and controlled by the
system's PC-2000)

LOOP THRU CONNECTOR
The male 3-pin XLR connector, along with the INTERCOM LINE IN connector,
is a composite of the intercom signal and the inserted program material. This
jack allows additional belt packs and/or branch boxes to be connected to the
intercom system for normal operation.
NORMAL A / ISOLATED C CONNECTOR
Male 3-pin XLR connector. When the CHANNEL SWITCH is set to "A" the
output functions like a standard intercom output (of the intercom material).
No program material from the system will be inserted on this output when the
channel switch is set to"B". Connect belt packs (via B3-2000) to this input for
isolated channel C operation.
INTERCOM LINE OUT CONNECTOR
A transformer balanced male XLR-3 connector which has the composite
intercom signal and inserted program material, for connection to an alternate
location, recorder or mixer.
