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
