INTRODUCTION

Thank you for purchasing the Focusrite RedNet R1.

RedNet R1 is a hardware monitor controller and headphone output device.
RedNet R1 controls Focusrite audio-over-IP devices such as Red 4Pre, Red 8Pre, Red 8Line, and Red 16Line monitor sections.
RedNet R1 has the capability to control the mic pres of the Red interfaces.
RedNet R1 features two main sections: Input Sources and Monitor Outputs.
Up to eight multichannel source groups will be selectable above and below the left screen, each with a select button that allows level adjustment and/or muting of a “spilled” source’s individual channels.
Each Source has a meter that displays the highest channel level within the source; there are also four talkback destination options.
Using either the built-in talkback mic or the rear-panel XLR input, the user can instruct the connected Red 4Pre, 8Pre, 8Line, or 16Line where to route the talkback signal.
On the right of the unit is the Monitor Output section. Here, the user can Solo or Mute each of the individual speaker outputs in up to a 7.1.4 workflow. Various Solo modes are offered.
A continuous pot with a large aluminum knob cap offers level control for the outputs, as well as for trim for individual monitors/speakers. Adjacent to this is the Mute, Dim, and Output Level Lock buttons.
Configuration of RedNet R1 is carried out using RedNet Control 2 software.

REDNET R1 OPERATION

First Use and Firmware Updates

Your RedNet R1 may require a firmware update when it is first installed and switched on. Firmware updates are initiated and handled automatically by the RedNet Control application.
It is important that the firmware update procedure is not interrupted – either by switching off power to the RedNet R1 or the computer on which RedNet Control is running, or by disconnecting either from the network.
From time to time Focusrite will release firmware updates within new versions of RedNet Control.
We recommend keeping all units up to date with the latest firmware version supplied with each new version of RedNet Control.
The RedNet Control application will automatically inform the user if there is a firmware update available.

Function Keys

The eight Function keys select the device’s operating model.
The switch color identifies its status: not illuminated shows that a switch cannot be selected; white
shows that a switch is selectable, any other color shows that the switch is active.
Screens 1 & 2 beneath each group of four buttons display the options & submenus available for each function. Options are selected using the twelve soft buttons provided with each screen.

REDNET CONTROL 2

RedNet Control 2 is Focusrite’s customizable software application for controlling and configuring RedNet, Red, and ISA range of interfaces. Graphical representation for each device shows control levels, function settings, signal meters, signal routing, and mixing – as well as providing status indicators for power supplies, clock, and the primary/secondary network connections.

REDNET R1 GUI

Graphical configuration for RedNet R1 is separated into five pages:

• Source Groups • Talkback
• Monitor Outputs • Cue Mixes
• Channel Mapping
Selecting a Red Device to Control
Use the drop-down in the header of any GUI page to select a device
Source Groups
The Source Groups page is used to configure to the eight input groups and to assign an audio source to each input channel.

Input Channel Configuration
Click the drop-down below each Source Group button to assign its channel configuration.
Two options are available:

• Presets – Select from the list of predefined channel configurations:

-Mono
– 5.1.2
– Stereo
– 5.1.4
– LCR| – 7.1.2
– 5.1
– 7.1.4
– 7.1
---|---

Presets allow the user to quickly set up the Source Groups (and Monitor Outputs) pages without being required to enter individual cross-points on the ‘Channel Mapping’ page.
The defined presets auto-fill the mapping table with predefined routing and mixing coefficients so that all fold-ups and fold-downs are done automatically, ie., a 7.1.4 source will be automatically routed to a 5.1 Output speaker configuration.

• Custom – Allows individual named formats and channel mapping table configurations.

Input Source Selection

The audio source assigned to each channel in a group is selected using its drop-down:
The list of sources available will depend on the device being controlled:
– Analogue 1-8/16 Red device-dependent
– ADAT 1-16
– S/PDIF 1-2
– Dante 1-32
– Playback (DAW) 1-64

• Channels can be renamed by double-clicking on their current name.

Monitor Outputs

The Monitor Outputs page is used to configure the output groups and to assign audio channels.

Output Type Selection
Click each drop-down to assign its output configuration:

– Mono
– Stereo
– LCR
– 5.1
– 7.1| – 5.1.2
– 5.1.4
– 7.1.2
– 7.1.4
– Custom (1 – 12 channels)
---|---

Output Destination Selection
The audio destination for each channel is assigned using its drop-down:

– Analogue 1-8/16 – ADAT 1-16
– S/PDIF 1-2| – Loopback 1-2
– Dante 1-32
---|---

• Channels can be renamed by double-clicking on their current channel number
• The output channels selected for Output Types 1-4 remain constant across all Input Source
  Groups, however, the routing and levels can be modified. See ‘Channel Mapping’ on the next page

A/B Switch Configuration
Select an output for ‘A’ (blue) and ‘B’ (orange) to assign the alternate Output Types to the front panel A/B Switch. The switch color will toggle (blue/orange) to indicate the currently selected output The switch will illuminate white if an A/B setup has been configured but the currently selected speaker is neither A nor B. The switch will dim if A/B has not been set up.

Channel Mapping

The Channel Mapping page displays the cross-point grid for each Source Group/Output Destination selection. Individual cross-points can be selected/deselected or level trimmed.

• The number of rows displayed corresponds to the number of channels in each Source Group
• An Input Source may be routed to multiple Outputs, to assist in the creation of fold-up or Fold-downs
• Each grid cross-point can be trimmed by clicking and entering a value via a keyboard
• The Solo-To-Front loudspeaker can be routed to only one Output Channel
  Adding channels (1–12) to the channels already in a source is non-destructive and will not change the routing. However, if the user changes from a 12 channel Source Group to a 10 channel Source Group, then the mix coefficients for channels 11 and 12 would be deleted – requiring them to be set up again if those channels were subsequently reinstated.

Channels Remaining in Mixer

A maximum of 32 channels are available. The number of channels remaining is shown above the Source Group buttons.
Talkback Channels may be reallocated to allow for additional group channels.

Talkback

The Talkback page displays the settings of the cross-point grid for the talkback Output selection and the headphone settings.

Talkback Routing
The routing table allows the user to route a single Talkback channel to 16 locations; the destination type is shown above the table.
Talkback 1–4 can also be sent to Cue mixes 1–8.
The Talkback Channels can be renamed.
Talkback Setup
Talkback Outline and icon will display as Green when connected to a Red device as expected.
A yellow ‘!’ indicates that routing is present but no audio is allowed to flow, refer to Dante Controller for details Clicking on the icon automatically updates the routing.When talkback is active, the monitors will dim by the amount set in the Dim Level window. Click to enter a value in dB.
Headphone Setup
The Headphone icon will also display as a Green tick when connected to a Red device as expected.
A yellow ‘!’ indicates that routing is present but no audio is allowed to flow, refer to Dante Controller for details

 I/O Level Information

Both the R1 and the Red range device under control are able to adjust the volume of the loudspeakers connected to the Red device’s analog outputs.
Having two control locations on the monitor system could result in there being either insufficient range or high sensitivity of the R1’s Output Level encoder. To avoid either possibility, we would advise using the following loudspeaker setup procedure:
Setting the Maximum Volume Level

1. Set all the analog outputs on the Red range unit to a low level (but not muted), using either the front panel controls or via RedNet Control
2. Turn the volume control on the R1 to maximum
3. Playa test signal/passage through the system
4. Slowly increase the channel volumes on the Red unit until you reach the highest loudness level that you would prefer coming from your speakers/headphones
5. Use the volume and/or Dim control on the R1 to reduce from this level. Now continue to use the R1 as the monitor system volume controller.

The procedure is only necessary for the analog outputs (digital outputs are affected only by the R1’s level control).

R1 Software| Users can trim the routing crosspoint levels by up to 6dB (in 1dB steps) from the Routing page for minor adjustments| R1: Pre-fade

Level Summing

When Summing behavior is enabled in the Tools menu, it automatically adjusts the output level to maintain a constant output when sources are added or removed.
The level of adjustment is 20 logs (1/n), ie., approximately 6dB, for every source summed.
