Description Hear Technology M8RX Switch Back M8RX The Hear Technologies Switch Back M8RX is professionally designed combining a personal Dante audio interface along with a multichannel headphone monitoring station intended for use in live sound and studio recording applications. It is made small enough to be clipped on a belt, it is capable of giving the musicians and broadcasters the option of recording their performance and monitoring their mix at the same time—with one single tool. The unit is also possible to be mounted on a mic stand or sit on a table for serving as a mini recording studio setup or a simple communication system. The M8RX comes featuring a total of eight channels of audio mixing: two studio-quality XLR microphone preamps that comes along with 48V phantom, a 3.5mm stereo input, and 4x4 Dante network audio inputs/outputs. The headphone amplifier is capable of delivering a 5W of power that is enabling its users to listen to your audio that comes along with the same high quality as the company's Hear Back PRO and OCTO personal monitoring systems. You are possible to individually control the level of the four Dante channels and the four analog inputs (with zero latency) for the creation of your perfect personal mix. The M8RX is connecting to a computer with a virtual sound card or a Dante-enabled mixing console with the use of the Ethernet port, by using an external PoE+ (Power-over-Ethernet+) injector (available separately). This is giving the unit the capability to be powered over the same Cat 6 cable used for transmitting data. Key Features 4x4 Dante I/O (4 Dante inputs and 4 Dante outputs) Two Combo XLR-1/4" TRS balanced inputs on channels 1 and 2 for connecting microphones or instruments Balanced 1/4" inputs automatically have 18 dB of padding over XLR inputs True 48V phantom power remotely/locally selectable on each microphone input 3.5mm unbalanced stereo input for auxiliary sources such as metronome, iPod, external microphone preamp, and more Master volume control for headphones Zero-latency headphone monitoring of the local analog inputs Easy access to all volume controls on face of unit Compact concentric volume knobs allow volume control of local inputs using the tip, and Dante inputs using the rings Dual-color signal and peak indicators on each input channel Gain, phantom power, and Dante status indictors tucked away on rear of unit Streamlined cable connections on rear of unit Powered by PoE+ Remotely/locally selectable LED color on top for easy color-coding and identification Other Features Two ultralow noise studio-quality discrete microphone preamplifiers Burr-Brown 24-bit enhanced multilevel delta-sigma D/A conversion Burr-Brown 24-bit delta-sigma A/D converters Ultralow distortion of 0.001% THD+N (even with 60 dB of gain on the microphone preamp) All 4 local analog input channels are made available on the Dante network as sources Local volume control of up to 8 channels of audio (4 local analog inputs and 4 Dante digital inputs) Remotely/locally adjustable microphone gain in selectable increments between 30 and 54 dB PoE+ power guarantees ground isolation when using multiple M8RX interfaces Standard CAT 6 cabling delivers power and Dante digital audio to the M8RX Small enough to be clipped on your belt (with the included belt clip) or mounted on a stand using the built-in standard camera-tripod mount (1/4"-20 thread) Optional Hear Technologies software for discovering M8RX interfaces on the network, controlling gain, phantom power, and LED color Can be used standalone (without a Dante network connection) as a small microphone preamp, analog mixer, and headphone amplifier Specifications Inputs Inputs A and B (Available on Dante Network as Channels 1 and 2):Mic InputsConfiguration: 2 x Mono, Balanced XLRFrequency Response: 10 Hz to 120 kHz +/-0.5 dB (Analog Input to Headphone Output)THD+N: 0.001% at 150 mV InputIMD: 0.004% at 150 mV InputX-TALK: -86 dBu at 150 mV InputSensitivity: -64 dBu (Gain at Max), -30 dBu (Gain at Min) Line Inputs:Frequency Response: 10 Hz to 120 kHz +/-0.5 dB (Analog Input to Headphone Output)THD+N: 0.001% at 1 V InputIMD: 0.004% at 1 V InputX-TALK: -91 dBu at 1 V InputSensitivity: 13 dBu (Gain at Max), +20 dBu (Gain at Min) Input C (Available on Dante Network as Channels 3 and 4):Configuration: Stereo, Unbalanced 1/8" / 3.5 mm TRSFrequency Response: 10 Hz to 120 kHz +/-0.5 dB (Analog Input to Headphone Output)THD+N: 0.005% at 200 mV InputIMD: 0.015% at 200 mV InputX-TALK: -70 dBu at 200 mV InputSensitivity: -10 dBu (Fixed Gain)IMD: Typically Less than 0.02% Headphone Amplifier Load Impedance: THD Less than 0.01%8 Ohms:1.2 W16 Ohms: 1.6 W25 Ohms: 2.0 W32 Ohms: 1.8 W50 Ohms: 1.5 W100 Ohms: 1.1 W200 Ohms: 500 mW600 Ohms: 220 mWInter Modulation Distortion: Typically Less than 0.02% Noise -97 dBu, A-Weighted Dynamic Range 122 dB Power PoE+ 36-52 VDC, 15 W Max Dimensions (H x W x D) 5.5 x 4.45 x 1.62" / 14 x 11.3 x 4.13 cm Weight 9.5 oz / 0.27 kg
