Focusrite - RedNet MP8R 8-Channel Remote Control Mic Preamp

8-Channel remote-controlled mic pre and A/D for Dante networks

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 Focusrites 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.

Key Features:

• Built-in redundancy with dual power and network connections
• Rugged roadworthy all-metal construction, high build quality, locking power and etherCON Ethernet connectors
• Eight Focusrite remote-controlled preamps with enhanced input level capability, and dual input impedance to deliver maximum performance when one mic feeds single or multiple pres
• Two outputs from each preamp: one direct and the other automatically gain-compensated to deliver a constant level
• Remote-controllable Gain, Phantom Power and High-Pass Filter from Yamaha CL and QL Series Consoles.
20dB pad, HPF and polarity inversion per input
• Operate locally, or remotely via RedNet Control software, Pro Tools, MIDI or OCA (Open Control Architecture available 2015 via firmware update)
• Precision low-latency conversion at up to 24-bit/192kHz, with best-in-class dynamic range and overall audio quality
• 6-segment LED level meters; OLED display indicates input gain and system information
• Compact 1U form factor
• Full interoperability with other Dante products and networks

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.
• Sample Rate: Orange LED for each: 44.1 kHz, 48 kHz, x2, x4.
• Pull Up/Down: Orange LED. Indicates that the unit is set to operate on a Dante pull up/down domain.
• Channel Signal Level: 6 level indicator LEDs for each channel. 3 Green LEDs, (-30dB, -18dB, -12dB); 2 orange LEDs (-6dB, -3dB); red LED (0dB/onset of clipping).
• Channel Select Buttons: 8
• Channel Function Controls: Info, Impedance, Pad, Phantom Power, HPF, Phase, Gain Encoder.
• Channel Display: Colour OLED. Displays Channel Name, Gain, Lock status (When on), Channel Number, Gain Compensation status (When on).

NETWORK MODES

Redundant: Allows unit to connect to two independent networks.
Switched: Connects both ports to integrated network switch allowing daisy-chaining of devices.
