Broadcast Tools SS 4.1 III

Unit is used and tested
PRODUCT DESCRIPTION:
The SS 4.1 III passively switches or routes a variety of electrical signals to a destination. 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, distortion, 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.
