Hear Technologies Switch Back M8RX Monitoring Interface

The Hear Technologies Switch Back M8RX Monitoring Interface is a personal interface used for live sound or recording, and also a multi-channel headphone monitoring system. With intuitive design and robust capabilities, it gives the musician a choice to play live, record, or monitor their mix all in one single tool.

The Hear Technologies Switch Back M8RX Monitoring Interface is a preamp and multi-channel headphone monitoring interface. While compact in size, the Hear Technologies Switch Back M8RX gives individuals options to use it in multiple ways, such as a mini recording studio setup or a simple communication system.

The research and design of the Hear Technologies Switch Back M8RX is what sets it apart. The Hear Technologies' engineers created the sleek look and feel making it perfect for hanging from a belt, mounting on a mic stand, or sitting on a table. The Hear Technologies Switch Back M8RX features a total of eight channels of audio mixing – two studio-quality microphone preamps, two channel line-inputs, and four Dante network audio inputs/outputs. The Hear Technologies Switch Back M8RX’s two mic preamps have a distortion spec below 0.001% along with zero-latency analog mixing and monitoring of the four analog inputs. With Ethernet capability becoming standard in most pro audio gear today, the Hear Technologies Switch Back M8RX includes a total of four channels of Dante network audio inputs/outputs.

Along with the same high quality headphone amplifier as in the Hear Back PRO and OCTO systems, the Hear Technologies Switch Back M8RX has 5 watts of headphone power and can be connected to a computer via the Ethernet port. The unit uses PoE power over the same Cat5e cable as the Ethernet. The Hear Technologies Switch Back M8RX is manufactured in the U.S. to ensure their customers get the quality they have come to expect from Hear Technologies.

Hear Technologies Switch Back M8RX Monitoring Interface Features
