CHAPTER 1: Specifications
Audio
Characteristics:
KVM/Serial/Audio models:
Signal format: Digitized at almost CD quality (16-bit
sampling at 38.4 kHz);
Signal levels: Line level (5 volts peak-to-peak
maximum);
Input impedance: 47 k
Ω
;
Signal direction: Simultaneous bidirectional;
Extra microphone support at Remote Unit: Pullup
resistor provides bias for condenser microphone;
optional amplification to +17 dB for external
microphone
Maximum
Distance:
5 m (16 ft.) from the Remote to the attached remote
equipment;

300 m (1000 ft.) between a Local and any other type of
Remote
NOTE
With high-quality cables, it might be possible to run
farther than 5 m (16 ft.) from the Remote Unit to attached
equipment.
