7.0 REAR PANEL CONTROLS & CONNECTOR
28 EXTENDED STATION LINK
This connector is used when 2 units (either 2 x PS
6379 or 1 x PS 6379 with PS 4379) should be linked
to form a 10 or 12 channel unit. When linked, 1 station
will be the master with an active speaker and
gooseneck/electret microphone. The speaker and
microphone of the other unit will be switched off. The
CALL ALL and TALK ALL signals will also be sent to
the channels of the extended unit.
29 NEAR STATION LINK
This connector is used to prevent system feedback
when two PS 6379 / PS 4379 are used close to each
other in the same room. This connection will dim the
listening level should the 'near station' talk on the
same channels the 'linked' station is listening to. The
dim factor can be adjusted per channel by pressing
and holding the 'set up lock' button and pressing and
holding the TALK button of the channel. The
adjustment is done by turning the Aux level/ IFB dim
knob.
