The ASW-822 is a professional 8X2 stereo
switcher for the demanding user. The high
impedance balanced input circuits reduce loading
effects and noise on the incoming signals. The low
output impedance of 66Ω provides 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
interface to computers or modems for RS-232, RS422 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 standalone unit or interfaced with additional switchers as
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.
The ASW-822 is an 8X2 matrix audio only switcher
with digital switching logic. High performance
circuitry is used throughout for long term
performance and reliability.
