SS 4x1 III Installation and Operation Manual
DESCRIPTION
PRODUCT DESCRIPTION
The SS 4.1 III passively switches or routes a variety of electrical signals to a desti-
nation. The SS 4.1 III selects any one of 4 stereo inputs to a single stereo output.
The SS 4.1 III provides PASSIVE switching through gold contact relays. The passive
switching means that the unit can route a signal in both directions (any one of 4
stereo inputs to a single destination, or a single source to any one of 4 destinations).
Due to the passive nature of the switching, any input level and impedance can be
used. Inputs may be balanced or unbalanced, while output levels, impedance, dis-
tortion, noise and balancing will match that of the selected input. In addition to their
normal use with audio signals, the unit can also be used to switch digital signals and
telephone lines.
The SS 4.1 III is controlled by means of front panel switches, contact closures, 5-volt
TTL/CMOS logic levels and/or a multi-drop serial port.
The SS 4.1 III has several unique features. The Power-Up feature allows the user to
select which of any source is active at power up, including the last source selected.
Audio mute allows the user to turn off the audio output when activated. A Step Input
provides a means of stepping though each source, including MOH Station Selection. A
Serial Port allows communication and operation from a computer’s serial port. Source
number one is configured by default to route audio to the output in the case of loss of
power to the unit. Non-selected sources are terminated with 10K W, load resistors.
APPLICATIONS
Some of the applications of the SS 4.1 III; Studio selection and routing; Audio pro-
cessing select; Exciter input select; Remote broadcast input selection; STL source
selection; Automation source selection; Multiple station Music On-Hold and/or PA
switching; EAS audio switching; ISDN or Phone hybrid feed selection; IFB selection;
Satellite audio channel switching and console monitor inputs and outputs selection.
FRONT PANEL DESCRIPTION
Source Switches:
Each switch represents an input to be routed to the switcher’s output. High quality tac-
tile switches will give the user years of dependable service. Each switch has an asso-
ciated LED indicator, which will illuminate when that particular source is routed to the
output. When a source is selected, the previous source will be deselected, (inter-
locked). The front panel is also equipped with a MUTE switch. This switch turns off
the audio output.
LEDs:
LED indicators will illuminate when the desired channel is selected. The Pwr/Ser
LED displays valid power and serial data activity. The mute LED denotes when
audio is off.
