Focusrite RedNet MP8R Mic Preamp

Developed from the RedNet 4 preamp, RedNet MP8R is an 8-channel mic preamplifier and A/D for the Dante audio-over-IP network that can be remote controlled. Building on the successes of earlier Focusrite preamp models, this pre offers lower noise, better Common Mode Rejection, and great dynamic range. Ideal for live sound/recording and broadcast environments, this preamp is very reliable.

The preamps in the MP8R deliver increased input level at a maximum of 28dBu, and dual input impedance of 10k or 2.4k ohms for greater flexibility when running several mic pres in parallel. Other features include a 20dB pad, high-pass filter, polarity inversion, and phantom power.

Channel design on the network allows splits (such as monitor/FOH) to be set up in the digital domain. Splits enable one engineer to control gain from the analog mic while a second receives an output level that is constant no matter what the analog mic’s gain setting. To allow for splits, the MP8R has a sophisticated gain tracking ability. On the network it appears as a 16-channel device: the first 8 channels are direct preamp feeds, the second 8 are automatically DSP level-compensated outputs sourced from the first 8 channels.

Remote control over preamps is possible in a variety of ways. RedNet Control software package, Pro Tools and MIDI, and OCA can all control the preamps remotely. Preamps can also be operated on the unit’s front panel, where you will see comprehensive monitoring indicators from 6-segment level metering, numeric gain display, and more.

In addition to the mic pres are 8 channels of A/D converters that operate at up to 192kHz/24-bit with minimum latency and class-leading dynamic range to deliver on Focusrite’s history of legendary quality.

Since this is a RedNet product, the MP8R interoperates with any other Dante audio-over-IP network components and infrastructure. Dual Ethernet ports with locking etherCON connectors offer several operating modes, such as daisy-chaining to other equipment and redundancy for protection against network failure. Manage patching and interconnection with Dante control software. Packaged in a compact 1U rack-mount form factor, the rugged MP8R can stand up to travel.
