About this User Guide This User Guide applies only to the RedNet MP8R Mic Preamplifier. It provides information about installing a RedNet MP8R and how to connect it into your system. A RedNet System User Guide is also available from the RedNet product pages of the Focusrite website.
INTRODUCTION Thank you for purchasing the Focusrite RedNet MP8R. RedNet MP8R is an 8-channel remote-controlled microphone preamplifier and A/D for the Dante audio-over-IP network. Specifically tailored for the road, live-sound and broadcast environments, each unit features network and power redundancy, rugged construction with latching connectors, remote control and remote monitoring.
Gain Compensated Split Outputs The RedNet MP8R is able to provide two outputs from each mic channel: one direct and a second automatically gain-compensated to deliver a constant level. This arrangement allows one engineer (FOH, say) to control the analogue mic gain without affecting the signal level being received by a second engineer on the network.
INSTALLATION GUIDE RedNet MP8R Connections and Features Front Panel AC Power Switch Switches power to both PSUs. Power Indicators: • PSU A – Illuminates when an AC input is applied and all DC outputs are present. • PSU B – Illuminates when an AC input is applied and all DC outputs are present.

Front Panel . . . Continued OLED Display Indicates the currently selected channel’s network name and its gain value and if either Front Panel Lockout or Gain Compensation is active. Also changes to display local and network configuration settings when in INFO mode. See below. Local Control Buttons: •...
Latching etherCON connector for the Dante network. Use standard Cat 5e or Cat 6 network cable to connect to a local Ethernet switch to connect the RedNet MP8R to the RedNet network. Adjacent to each network socket are LEDs which illuminate to indicate a valid network connection plus network activity.
Power Connection IEC Power Cord Retaining Clips RedNet MP8R is supplied with two IEC power cord retaining clips. These prevent accidental disconnection of a power cord during use. When the unit is first installed, the retaining clips will need to be attached to the power input sockets on the rear panel.
RedNet MP8R dimensions are illustrated in the diagram above. RedNet MP8R requires 1U of vertical rack space and at least 440mm of rack depth, to allow for cables. RedNet MP8R weighs 5.75 kg and for installations in a fixed environment (eg., a studio), the front-panel mounting screws will provide adequate support.
If a Network Master is not present then the unit can be chosen as the Network Master by the user. Pull Up and Pull Down Operation RedNet MP8R is able to operate at a specified pull up or pull down percentage as selected in the Dante Controller application.
RedNet Control will reflect the status of the RedNet units present in the system, presenting an image representing each hardware unit. The illustration above shows the RedNet MP8R RedNet Control image. The signal level, gain and input function settings are indicated for each channel.
Notes: - The default is “Off” - 16 channels are available, allowing a maximum of 16 independent RedNet MP8R control paths - Two devices should not be set to the same MIDI channel - MIDI channel selection is saved with the computer, not the device. Therefore, when controlling the same unit from a different computer, the MIDI channel allocation may no longer be the same www.focusrite.com...
