Splitter Assembly – Models 4022 and 4025A
The splitter assemblies connect the control stations with the central electronics via 25-pair cable with micro-ribbon connectors.
The Model 4022 features a single male connector paralleling two (2) female connectors to connect two (2) controls/stations to
the central electronics.
The Model 4025A features a single male connector with four (4) female connectors for use with up to four (4) control stations.
All connectors are held securely in place with a snap-on cover housing.
Special Options
A return-send function may be incorporated with some small modifications. This feature allows the talent at the User Station
to communicate with the Control Stations via a closed-circuit loop. This is done at the User Station by switching in an extra
load, usually a lamp, across the feed to that station. Sensor circuits in the Central Electronics turn on relay-driving circuits, the
outputs of which connect to a 9-pin miniature D connector on the rear panel. This allows an external relay to be used to
transfer the announcer’s microphone from the program line to a monitor amplifier or intercom in the control room. The person
at the control station may now listen to the announcer without having the signal go over the air.
