MODEL PAF-821

MADE IN THE USA

FEATURES

‹8 Inputs X2

‹Digital Switching

‹Balanced Differential

‹One Rack Unit Cabinet

‹Output Impedance, 66Ω

‹RS-232, RS-422, RS-485

The PAF-821 is a professional stereo audio follow switcher for its video companion. 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 computer or modem for RS-232 control 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 VSW series switchers or RS-232 from a computer. Multiple switchers can be controlled by a single remote control panel, PSR series. The PAF-821 is RS-232 controlled and remote control is RS-422 or RS-485 via an RJ11 telephone connector and cable assembly.

The PAF-821 is the stereo audio follow companion 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.
