SS 4x1 III Installation and Operation Manual
DESCRIPTION
REAR PANEL DESCRIPTION
The rear panel contains the inputs, outputs and remote control interfacing connec-
tors. Audio inputs, outputs and remote control connections are pluggable screw ter-
minals. A RJ-11 modular jack is provided for the multi-drop serial port.
Power:
Connect the 2.1mm coaxial type power connector into the unit and the 9 VAC @ 1
amp wall transformer into a 120 Vac 50-60 Hz power source. The front panel
Pwr/Ser LED indicates when power is applied to the unit. (CE 220 Vac 50-60 Hz
wall transformer OPTIONAL)
Audio Signal Connector:
The SS 4.1 III is supplied with Pluggable Screw terminals (Euro) and Mating con-
nectors. Channel and polarity designators can be found on the chassis, as viewed
from the rear.
“Remote” Control Connector:
Pluggable Screw terminals (Euro) and mating connectors are provided for connec-
tion to equipment, which will remotely control the SS 4.1 III. Pulsing the “MUTE”
input to ground (low) would turn off the output of the SS 4.1 III until a front panel
source switch is pressed, a remote control input is activated or the unit is powered
up. Pulsing the “STEP” input to ground will step the unit one source for each low
to high transition on this input. Automatic sequence may be accomplished by hold-
ing the step input low for two seconds. The unit will now step to each source every
50 seconds. The step input is helpful in freeing up valuable remote control channels.
This feature may also be used to sequence through multiple station air monitor sig-
nals for program on-hold feed.
