Focusrite RedNet MP8R
RedNet MP8R is an 8-channel remote-controlled microphone preamplifier and A/D for the Dante audio-over-IP network. Developed from the RedNet 4 studio remote-controlled microphone preamp, and incorporating input from leading live sound practitioners during its development, the MP8R provides a wealth of features that make it particularly applicable to the live sound/recording and broadcast environments, where reliability is paramount. Dual Ethernet ports are provided, with several operating modes including daisy-chaining and redundancy confirmed by front-panel indicators. Two separate power supplies with fault detection capability are included, with separate power input sockets on the rear panel. Power failure is indicated both remotely and on the front panel. The MP8R features a rugged, roadworthy exterior and maximum internal build quality. In addition, the MP8R offers a compact 1U rack-mount form factor.
Key Features
• 8-channel remote-controlled mic pre with A/D and Dante audio-over-IP networking — Eight remote-controlled Focusrite mic preamps and precision A/D conversion at up to 192kHz provide a compact, rugged interface compatible with any Dante network hardware and infrastructure.
• Power and Ethernet redundancy — MP8R is ideal for critical path applications, with dual power supplies that include local and remote status indication, and dual Ethernet ports.
• Tailored for the Live Sound environment — MP8R includes rugged road-worthy construction, high build quality and built-in redundancy for power and network connections.
• Flexible input capability — Including a new, enhanced input level capability, MP8R mic pres include dual input impedance to deliver maximum performance in a variety of configurations.
• Remote or local control of mic pre parameters — In addition to mic gain, MP8R mic pres offer 20dB Pad, High-pass filter and polarity inversion, all controllable remotely or from the front panel.
• Multiple remote control possibilities — MP8R has full front panel control, but can most effectively be operated via RedNet Control software on a host computer, or directly via Pro Tools or MIDI, or OCA (Open Control Architecture). RedNet Control software allows full routing and control from your audio computer system via a software control panel — without hardware patching.
• Best-in-class Focusrite A/D conversion — The eight mic pres are followed by precision low-latency conversion at up to 24-bit 192kHz, offering best-in-class dynamic range.
• Comprehensive indicators tell status at a glance —Two power LEDs (one per PSU) are provided, along with remote indication of PSU status. 6-segment metering provides useful level indication for each channel and function indicators indicate individual preamp settings. An OLED display indicates input gain and system information.
• Separate outputs with automatic gain compensation — Each preamp provides two outputs: one direct and the other that is automatically gain-compensated to deliver a constant level. This gain tracking capability allows "splits", such as FOH/monitor, to be carried out in the digital domain, permitting one engineer to control the analogue mic gain while a second receives a gain-compensated output.
• Superb road-worthy build quality — Designed for life on the road, MP8R features etherCON locking Ethernet connectors, highest quality Neutrik XLR connectors and locking power input sockets. The compact 1U all-metal enclosure is ruggedly constructed and redundant power and Ethernet facilities maximise reliability in the field.
