Overview
Focusrite AMS-REDNET-MP8R
RedNet MP8R is an 8-channel remote-controlled microphone preamplifier and A/D for the Dante audio-over-IP network, designed specifically for the live sound/recording and broadcast environments, and other workflows where reliability is paramount, with Ethernet and power supply redundancy. The MP8R features eight high-quality remote-controlled mic preamps developed specifically for the RedNet range, and backed by thirty years of mic preamplifier development. Each preamp has a dual input impedance of 10k or 2.4k ohms, allowing flexibility when running multiple mic pres in parallel. The device includes eight auxiliary outputs with automatic DSP-based gain tracking for digital “splits”. Following the mic pres are eight channels of Focusrite’s legendary high-precision A/D converters, operating at up to 192kHz/24-bit with minimum latency and offering class-leading dynamic range and overall performance. The MP8R features a rugged, roadworthy exterior and high internal build quality. In addition, the unit offers a compact 1U rack-mount form factor.

Front Panel Indicators
|
|
| Primary PSU (A) | Green LED. Illuminates when an AC input is applied and all DC outputs are present. |
| Secondary PSU (B) | Green LED. Illuminates when an AC input is applied and all DC outputs are present. |
| Primary Network | Green LED. Indicates that a network connection is present on primary port when in redundant mode. When in Switched mode, a valid network connection at either Primary or Secondary network port will cause this LED to illuminate. |
| Secondary Network | Green LED. Indicates that a network connection is present on secondary port when in redundant mode. Not used in switched mode. |
| Network Locked | Green LED. When unit is network slave, shows valid network lock. When unit is network master, shows lock to internal clock. |
