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.
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.
Installation Guide Unit connections and features RedNet 3 - Front Panel 4 6 5 2 3 1 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.
6. CLOCK – One of five yellow LEDs will be illuminated to confirm the currently selected source of clock for the RedNet 3 unit if it is currently selected as Preferred Master in RedNet Control. The clock source is selected in software from RedNet Control, and the options are: • AES – sync is derived from Channel 1 of the AES/EBU digital audio input. • ADAT – sync is derived from ADAT input 1. • S/PDIF – an S/PDIF digital audio signal connected at the rear panel may be used as the sync source.
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.
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.
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 “BreakOut” (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.
