The PAF-823 is a professional stereo audio follow

switcher for the video companion, NO BUTTONS.

Thehighimpedancebalancedinputcircuitsreduce

loading effects and noise on the incoming signals.

The low output impedance of 66Ωprovides a

maximum level of +24dBu. The input and output

connections are printed circuit spring terminal

blocks. The terminal blocks provide reliable

clamping action for secure and reliable operation

due to a force amplifying hinge motion.

A nine pin female D connector provides serial

interfacetocomputerormodemforRS-232control

which is standard in all units. The switcher is

available in other models for stereo, mono or four

channel operation.

The RJ-11 telephone connector allows servral

audio follow units operate in tandem, so several

levels of audio may be achieved.

There are no push buttons on the front panel as

the PAF-823 gets its control functions from the

VSWseriesswitchersorRS-232fromacomputer.

Multiple switchers can be controlled by a single

remotecontrolpanel, PSRseries.ThePAF-823is

RS-232controlledandremotecontrolisRS-422or

RS-485 via an RJ11 telephone connector and

cable assembly.

The ASW-820 is a stereo audio-only switcher with

digital switching logic combined with high

performance audio circuitry to form the foundation

for the next generation of audio routing switchers.

All VSW, ASW, PAF and PSR series units

occupies on rack space. Each unit includes a

power supply for reliable operation.

The PAF-823 operates as an audio follow for the

VSW-800 series video switchers or as a stand-a-

lone audio switcher.
