INTRODUCTION

Thank you for purchasing this Focusrite RedNet 4.

RedNet 4 is a multichannel analogue mic/line preampliﬁer 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.

In RedNet 4, Focusrite mic preamp technology is combined with 24-bit A-D conversion at sample rates of up to 192 kHz. It provides eight analogue inputs - each of which may be either microphone or line level - plus two front panel DI inputs. Each mic input has switchable 48 V phantom power and a high-pass ﬁlter, and pairs of channels may be ganged for stereo operation. As with other RedNet analogue interfaces, JetPLL™ technology and up to 119 dB of dynamic range are standard.

Mic preamp parameters, including analogue gain, can be controlled both from the front panel, or remotely via the Ethernet connection using RedNet Control software.

The inputs are electronically balanced, with the mic inputs on standard 3-pin XLR connectors and the line inputs on a 25-pin Dsub connector. Channels 1 and 2 can additionally be conﬁgured as DI inputs, for direct connection of instruments to ¼” jack sockets on the front panel.

The front panel has a rotary gain control with numeric display, eight channel select buttons and switches for mic/line/DI selection, phantom power and high-pass ﬁlter. It also has LEDs conﬁrming network status, sample rate and per-channel signal level.
