The PAF-820 is a professional stereo audio follow
switcher for the video companion. The high
impedance balanced input circuits reduce loading
effectsandnoiseontheincoming signals. The low
output impedance of 66Ωprovides a maximum
levelof+24dBu. The input and output connections
are printed circuit spring terminal blocks. The
terminalblocksprovidereliableclampingactionfor
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 several
audio follow units to operate in tandem, so several
levels of audio may be achieved.
Multiple switchers can be controlled by a single
remotecontrolpanel, PSRseries.ThePAF-820is
RS-232controlledandremotecontrolisRS-422or
RS-485 via an RJ11 telephone connector and
cable assembly.
TheASW-820will operate asastereoaudiofollow
unit or as a stand-alone audio switcher. The
switcher incorporates digital switching logic and
high performance audio circuitry that forms the
foundation for excellent reliability. All VSW, ASW,
PAFandPSRseriesunitsoccupiesonrackspace.
The PAF-820 will operate with the PSR-824
remote control and the VSW-821 video switcher.
Several PSR-824 remotes may be attached to
PAF-820 for controlling from many locations. All
remote locations may select the audio source
