  1. Instrument Inputs. Two high-impedance unbalanced inputs on 1/4” jack sockets.

  2. Input Select buttons provide direct access to the control and menu settings for analogue input channels [1-4/1–8].

  3. The Input Encoder and its associated Input Display are used to select and adjust the configuration menu settings for the input channels; it also functions as the input gain control for the active channel.

  4. The Level Meter Display is an eight-channel, switchable LCD meter which is able to display groups of input and output signals.

  5. The Output Encoder functions as the volume control for the monitor and headphone outputs. It is also used to configure the global system settings, control the meter selection and select the monitor dim and mute features. Its function is determined by the adjacent Monitor, Meter and Headphone Select buttons.

  6. The Meter button calls up the selection menu for the level meters onto the Output Display.

  7. The Monitor button assigns the Output Encoder to the monitor loudspeaker functions.

    Pressing the Meter and Monitor buttons simultaneously enters the Global configuration menu, where host, clock and power-up settings are assigned.

  8. The Headphone 1 and 2 buttons assign the Output Encoder to the selected headphone control functions.

  9. Headphone Outputs are standard 1/4” TRS jacks.

Rear Panel – Red 4Pre/Red 8Pre

Red 8Pre shown:

Red_8Pre_Rear_Annotated_Line_Drawing.png

  1. Standard IEC receptacle for AC mains. features a ‘Universal’ PSU, enabling it to operate on any supply voltage between 100 and 240 V AC

  2. Network. Two RJ45 Ethernet connectors for the Dante network. The ports can be configured as either primary and secondary on redundant systems – where two independent networks are available, or as a two-port switch to allow the daisy-chaining of additional units.

  3. Word Clock – Input allows synchronisation to word clock.

  4. Word Clock – Output provides an output of the chosen system clock reference.

  5. Loop Sync I/O sockets allows integration with a standard Pro Tools system I/O chain.

  6. Dual Thunderbolt Connection. Two ports allow either direct or chained connection to your workstation/external monitors – the chaining/linking of other Red devices is not permitted.

  7. Pro Tools | HD Interface. Two Mini DigiLink Primary connectors; use Mini DigiLink cables to connect to a Pro Tools | HDX PCIe card or Pro Tools | HD Native system.

  8. Line Outputs on [one/two] DB25 female connector(s).

    DB25 connectors are wired according to the AES59 Standard (also known as the TASCAM Analogue standard).

  9. Line Inputs on [one/two] DB25 female connector(s).

    Note that Line input circuits [1-4/1-8] can be re-assigned to the Instrument (circuits 1&2) and/or Microphone connectors so may not always be available on the DB25 connector. See page 14 for further information.

  10. *Microphone Inputs (Red 4Pre) on four latching XLR-3 female connectors.

  11. *Microphone Inputs (Red 8Pre) on DB25 female connector.

    Note that a DB25 male to XLR-3 female 8-way adapter loom will be required for mic leads with individual XLRs.

  12. ADAT I/O 1 and 2. Two independent 8-channel ADAT optical inputs and outputs using standard TOSLINK™️ connectors. Optical I/O 1 can also be used in ‘Optical S/PDIF’ mode.

  13. S/PDIF I/O. 2-channel digital interface on RCA (phono) connectors.

  14. Monitor Outputs. Balanced 1/4” TRS jacks for connection of Left and Right monitor loudspeakers. Outputs are at line-level so unpowered speakers will require external amplification.

Physical Characteristics

Red_Range_Front_Dimensions.png

Case dimensions are illustrated in the diagram above.

Red range units require 1U of vertical rack space. Allow an additional 75mm of rack depth behind each unit to allow for cables. For installations in a fixed environment (eg., a studio), the front-panel rack mountings* will provide adequate support. However, if the units are to be used in a mobile situation (eg., flight-cased for touring, etc.), it is recommended that side support rails or shelves are used within the rack. The weight of each unit is shown in the table below.

*Always use M6 bolts and cage nuts specifically designed for 19” equipment racks. An Internet search using the phrase “M6 cage nuts“ will reveal suitable components.

Cooling is by fan assistance from side to side; the fans used are low-speed and low-noise. Do not mount the unit immediately above any other equipment which generates significant heat, for example, a power amplifier. Also, ensure that when mounted in a rack the side vents are not obstructed.

Note

The maximum operating environmental temperature is 40°C / 104°F.

Power Requirements

Red range units are mains powered and incorporate a ‘Universal’ power supply which can operate on any AC mains voltage from 100 V to 240 V. The AC connection is via a standard 3-pin IEC connector on the rear panel. Power consumption is shown in the table.

A mating IEC cable is supplied with each unit – this should be terminated with a mains plug of the correct type for your country.

Note

There are no fuses or other user-replaceable components of any type in any unit. Please refer all servicing issues to our Customer Support Team.
