Hear Technologies M8RX Switch Back Analog and DANTE Multi-Channel Headphone Monitoring Interface

With intuitive design and robust capabilities, the Switch Back M8RX is actually two products in one. This gives the musician a choice to play live, record, or monitor their mix all in one single tool. The M8RX is a personal interface to be used for live sound or recording, and also a multi-channel headphone monitoring system. While compact in size, the 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 M8RX is what sets it apart. Our 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 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 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 M8RX includes a total of four channels of Dante network audio inputs/outputs.

Key Features

• 4 x 4 Dante (4 Dante Inputs and 4 Dante Outputs)
• Master volume control for headphones
• Easy access to all volume controls on face of unit
• Dual-color signal and peak indicators on each input channel
• Concentric volume control on each channel reduces space and simplifies user interface by placing local inputs on the tips and Dante inputs on the rings of each knob
• True 48-volt phantom power remotely/locally selectable on each microphone input
• Burr-Brown 24-bit Delta-Sigma A/D converters
• Burr-Brown 24-bit enhanced multilevel delta-sigma D/A conversion
• 1/8" unbalanced stereo input for auxiliary sources such as metronome, iPod, external microphone preamp, etc.
• Balanced 1/4" inputs automatically have 18dB of padding over XLR inputs
• Combo XLR & 1/4" TRS balanced inputs on channels 1 & 2 for connecting microphones or instruments
• 100/1000 BaseT Ethernet
• Powered by Power over Ethernet (PoE+) guarantees ground isolation between M8RX interfaces Zero latency headphone monitoring of the local analog inputs
• Gain, phantom power, and Dante status indictors tucked away on rear of unit
• Streamlined cable connections on rear of unit
