Page 5: Introduction
INTRODUCTION Thank you for purchasing this Focusrite RedNet 3. RedNet 3 is a multichannel, bidirectional digital audio interface for use with a RedNet digital audio networking system. RedNet is a powerful, low latency, digital audio networking system designed specifically for music, recording studio and broadcast applications. It is based on Audinate’s Dante™, a well-established audio networking technology known for its extreme robustness. Dante - and the RedNet system - is capable of transporting up to 512 channels of bidirectional audio (at 48 kHz sample rate) over a single Gigabit Ethernet link. The number of channels available in your DAW will depend on the host method being used. RedNet 3 provides up to 64 channels of digital I/O (32 inputs, 32 outputs), in ADAT format. The ADAT connectivity consists of eight optical inputs and eight optical outputs. ADAT Inputs 1 to 4 and Outputs 1 to 4 can each carry 8 audio channels at 44.1 or 48 kHz. Outputs 5 to 8 duplicate the lower-numbered ports at these sample rates. At higher sample rates, Inputs 5 to 8 and Outputs 5 to 8 are used for the higher-numbered channels, and the per-port channel count is reduced from 8 to 4 (at 96 kHz) or to 2 (at 192 kHz). The AES/EBU I/O makes Input and Output channels 1 to 8 available on a 25-pin Dsub connector, in addition to the ADAT format at the optical ports. Sample Rate Conversion (SRC) is available on the AES/EBU inputs; this may be selected from RedNet Control. (Note that the AES/EBU digital format encodes audio channels in pairs.) RedNet 3 is also provided with an S/PDIF input and an S/PDIF output; these carry Channels 1 and 2. Sample Rate Converters (SRCs) are fitted to the S/PDIF input. Word Clock Input and Word Clock Output connectors permit RedNet 3 to be either a master or slave to other digital audio devices outside the RedNet network. The front panel has LEDs confirming the unit’s network status, sample rate and sync source, together... -
Page 6: About This User Guide
About this User Guide This User Guide applies only to the RedNet 3 digital interface. It provides information about installing a RedNet 3 and how to connect it into your studio system. You will also find a copy of the RedNet System User Guide included with the unit. This Guide provides a detailed explanation of the RedNet system concept, to help you achieve a thorough understanding of its capabilities. We recommend that all users, including those already experienced in digital audio networking, take the time to read through the System User Guide so that you are fully aware of all the possibilities that RedNet and its software has to offer. If either User Guide does not provide the information you need, be sure to consult www.focusrite.com/rednet, which contains a comprehensive collection of common technical support queries.

Page 7: Installation Guide
INSTALLATION GUIDE Unit connections and features RedNet 3 - Front Panel 1. AC Power switch 2. AES ACTIVITY – four green LEDs which illuminate when a valid AES/EBU digital audio signal is present at the corresponding AES/EBU input. A further set of four indicates the presence of a signal at each of the AES/EBU outputs. Note that the numbering is in pairs, as one AES/EBU signal (input or output) corresponds to two audio channels. 3. ADAT ACTIVITY – two sets of four green LEDs which illuminate when a valid digital audio signal in ADAT format is present at the corresponding input or output TOSLINK port. Note... -

• INTERNAL – synchronisation is derived from the RedNet 3’s internal clock. If any of the external sync sources are selected, but no valid signal is available, the unit’s clock source will switch automatically to internal sync. The selected clock (internal or external) is available at a Word Clock Output connector for connection to other digital audio devices outside the RedNet network. RedNet 3 - Rear Panel 7. AES/EBU INPUTS/OUTPUTS – 25-pin female Dsub connector, conforming to AES 59, for connecting up to 8 digital audio sources (4 AES/EBU pairs) to the RedNet system, and also for outputting up to 8 digital audio channels (4 AES/EBU pairs). See page 12 for connector details. - Page 9 11. S/PDIF INPUT – phono socket allowing connection of the S/PDIF output of a digital audio device. The two channels connected here may be placed on the RedNet network, as selected in RedNet Control. The S/PDIF signal connected here may also be used as the unit’s sync source. 12. WORD CLOCK INPUT – a BNC socket for the connection of a dedicated word clock sync signal, typically derived from a studio master clock source used to sync all the interconnected digital audio units in the system. 13. WORD CLOCK OUTPUT – a BNC socket from which a word clock signal may be obtained for connection to other digital audio devices outside the RedNet network. The clock signal available here will be derived from the source selected in software, and confirmed on the RedNet 3’s front panel by LED.

Page 10: Physical Characteristics
Physical Characteristics RedNet 3’s dimensions are shown in the diagram below: 247.5mm / 9.74" 465.0mm / 18.30" 76.2mm / 3" RedNet 3 requires 2U of vertical rackspace and at least 350 mm of rack depth, to allow for cables. RedNet 3 weighs 4.34 kg, and for installations in a fixed environment (e.g., a studio), the front panel mounting screws will provide adequate support. If the units are to be used in a mobile situation (e.g., flight-cased for touring, etc.), consideration should be given to using side support rails within the rack. RedNet 3 generates no significant heat, and is cooled by natural convection. We recommend that the unit should not be used in locations where the ambient temperature is greater than 30°C. Ventilation is via slots in the enclosure at both sides. Do not mount RedNet 3 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. Power requirements RedNet 3 is mains-powered. It incorporates a ‘Universal’ power supply, which can operate on any AC mains voltage from 100 V to 240 V. The AC connection is made via a standard 3-pin IEC connector on the rear panel. A mating IEC cable is supplied with the unit, which should be terminated with a mains... -
Page 11: Other Rednet System Components
OTHER REDNET SYSTEM COMPONENTS The RedNet hardware range includes various types of I/O interface and a PCIe digital audio interface card which is installed in the system’s host computer. All the I/O units can be considered as “Break- Out” (and/or “Break-In”) boxes to/from the network, and all are built in mains-powered, 2U 19” rackmounting housings. There are also three software items, RedNet Control (see below), Dante Controller and Dante Virtual Soundcard. USING REDNET CONTROL A virtual depiction of RedNet 3 will appear on-screen in RedNet Control when a unit is included in the active system. Port activity: Each of the RedNet 3’s 32 inputs and 32 outputs has a virtual LED which illuminates to confirm the presence of an audio signal on that channel. Note that as the maximum number of channels is reduced at higher sample rates, the number of LEDs which may appear active is... -
