Hall Research HR-101-R Microphone and Line-Level Audio Extender Receiver

The Model HR-101-R Receiver has an ST fiber optic input connector to receive audio from the sender. It provides a stereo line level output on 3.5mm mini-stereo jack and a SPDIF digital audio output on a RCA connector.

The HR-101 a professional quality Fiber-Optic audio extender kit. comprised of two units: a sender (HR-101-S) and a receiver (HR-101-R). The HR-101 can extend an audio over a single multi-mode fiber optic cable spanning distances of over 1000m (3280ft). For lengths of upto 500 meters OM2 or OM3 cables are recommended, and for distances of over 500 meters OM3 cable is recommended.

The HR-101-S is a compact and professional grade microphone amplifier with stereo line-level mix that can be used as a stand-alone device, or paired with the HR-101-R to extend audio over long distances on fiber optic cables.
