The ASW-822 is a professional 8X2 stereo
switcher for the demanding user. The high
impedance balanced input circuits reduce loading
effectsandnoiseontheincomingsignals.Thelow
output impedance of 66Ωprovides a maximum
levelof+24dBu.Theinputand 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
interfacetocomputersormodemsforRS-232,RS-
422 and RS-485 control which is standard in all
"820" series switchers.
Two groups of eight (8) push buttons on the front
panel are high quality key switches for vibration
free operation. A seven segment LED read-out on
the front panel shows the source audio number
selected. Each switcher can operate as a stand-
aloneunitorinterfacedwithadditionalswitchersas
multiple source routers. Multiple switchers can be
controlled by a single remote control panel, PSR-
821. Remote control is provided via an RJ-11
telephone connector.

with digital switching logic. High performance
circuitry is used throughout for long term
