The PAF-821 is a professional stereo audio follow
switcher for its video companion. The high
impedance balanced input circuits reduce loading
effectsandnoiseontheincomingsignals.Thelow
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.
There are no push buttons on the front panel as
the PAF-821 gets its control functions from the
VSWseriesswitchers orRS-232fromacomputer.
Multiple switchers can be controlled by a single
remotecontrolpanel, PSRseries.ThePAF-821is
RS-232controlledandremotecontrolisRS-422or
RS-485 via an RJ11 telephone connector and
cable assembly.
ThePAF-821isthestereoaudiofollowcompanion
switcher for the VSW-822 video switche. With
digital switching logic combined with high
performance audio circuitry this forms 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.
