Receiver

The VoiceLift VLR 102 receiver receives infrared signals from the VoiceLift VLP 102

pendant microphone. The receiver outputs a balanced -10 dBV line level signal via

an RJ-45 connector. Integrated DSP performs feedback suppression.

The VLR 102 receiver consists of the following major components:

Receiver doe and base plate

The tinted sensor dome ﬁlters ambient light, but lets the microphone’s IR signals

pass through to the sensors. The dome is attached to the receiver base plate by four

tabs that are inserted into slots on the base plate.

The maximum cable distance between the receiver and a secondary receiver, or

between two secondary receivers, is 100 feet (30.4 m); the minimum distance

is 5 feet (1.5 m). Total cable length in the system should not exceed 300 feet
