Hall Research HR-101-S XLR Mic Amplifier with Stereo Line Level Mixer, Phantom Power

What sets the HR-101-S XLR Mic Amplifier with Stereo Line Level Mixer apart is its professional-grade, compact design, and its versatility as a stand-alone device or in conjunction with the HR-101-R for extended audio transmission over fiber optic cables. This high-quality audio equipment provides a balanced microphone input via an XLR connector, coupled with a stereo line level input through a 3.5mm mini-stereo jack, accommodating a wide array of microphone types.

The HR-101-S is equipped with an adjustable-gain, low noise microphone preamp, offering a gain range of +34 to +54 db (or x50 to x500). This feature ensures optimal audio quality by preventing saturation and clipping due to excessive gain, with a digital VU meter on the front panel providing a visual indication of volume levels.

Phantom power, essential for condenser microphones, can be easily activated via a front panel switch. The stereo line input, located on a standard 3.5mm (1/8 inch) connector, seamlessly mixes with the amplified microphone signal. This allows presenters, for instance, to connect their PC's audio to the line input and their microphone to the XLR, resulting in a harmonious blend of the speaker's voice with the PC audio.

Finally, the HR-101-S boasts both stereo analog outputs (on 3.5mm) and SPDIF digital outputs (on RCA), as well as a fiber-optic ST connector. This feature enables the transmission of audio signals over long cables up to 3,280 ft. to a compatible receiver, making it an ideal choice for professional live performances and recording studios.
