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 with data activity for each group of eight digital inputs and outputs.
