FOC-REDNET4

Focusrite RedNet 4 - 8-preamp / Line / DI Ethernet Audio Interface

The RedNet 4 by Focusrite is a premium 8-channel RedNet microphone preamplifier, with optional line and instrument input connectors for input flexibility. The RedNet 4 can be integrated via ethernet into your RenNet Dante interface network via ethernet.


    • Focusrite RedNet 4 PRODUCT FEATURES:

      RedNet 4 Overview:
      RedNet 4 adds eight of the latest remote-controlled Focusrite mic preamps / line inputs to your RedNet system through a single Ethernet cable. With two selectable DI’s, RedNet 4 provides an effective range of analogue inputs for your system. The unit includes Focusrite’s world-class precision A-D conversion. Mic/Line/DI selection, gain, phantom power, HPF and metering are also accessible from the front panel. The benefit of remote control microphone pre-amp gain is that you can keep the mic pre close to the source (so the analogue cable run is minimal) while still setting gain stages from the control room.

      RedNet 4 Key Features:
      Eight high-quality Focusrite 'RedNet' mic preamps
      DC-coupled signal path for characteristically open and transparent sound
      Selectable line and DI inputs for input flexibility
      Remote-controllable Gain, Phantom Power and High-Pass Filter from Yamaha CL and QL Series Consoles.
      Dynamic range: 119dB
      THD+Noise: <0.001%
      Mic input Level up to +16dBu
      Max mic input gain: 63dB
      JetPLL™ jitter-reduction technology
      Comprehensive remote control software with powerful graphic user interface


      RedNet
      Studio quality sound meets digital audio networking…
      RedNet is Focusrite’s flagship range of modular Ethernet-networked audio interfaces that harnesses the power of Audinate’s tried and tested Dante digital audio networking system to bring studio quality sound to any modern audio application.
      Designed with multiple audio applications in mind – from Live Sound rigs to Multi-room Recording Studios, Houses of Worship, Audio Distribution Installations, Post Production environments and anything in-between – fundamentally RedNet is an extremely scalable, near zero latency audio distribution system that can be used to expand I/O channel count, interface digital components, and/or bridge between Pro Tools|HD or MADI and the Dante audio network.
      Incorporating Focusrite’s most advanced AD/DA conversion to date, rock-stable JetPLL clocking and premium multi-layered board circuitry, RedNet is no exception to the company’s philosophy that ‘Sound is Everything’. With every design detail meticulously engineered, RedNet is a step above its I/O competition, providing some of the most transparent and pristine audio quality available – with the added benefit of the systems’ revolutionary networking capabilities.

      Hosting RedNet
      How does RedNet interface with my computer?
      There are three methods of connecting the RedNet network to your computer: RedNet 5 (for Pro Tools HD, Pro Tools HDX and Pro Tools HD Native), the RedNet PCIe card (for ASIO and Core Audio applications) and directly into your computer’s Ethernet port with DVS or ‘Dante Virtual Soundcard’.

      Pro Tools HD:
      RedNet 5 is a bridge between Pro Tools HD systems and the RedNet network, delivering the level of latency and I/O count you would expect from your Pro Tools HD system, to the simplicity and convenience of Ethernet.
      Core Audio Applications:
      For Core Audio and ASIO applications such as Logic and Nuendo, the RedNet PCIe card can be fitted to Windows or Mac computers with a standard PCIe card slot. It delivers 128 channels I/O at 96kHz sampling, with three milliseconds latency at 96kHz*. A standard RJ45 Ethernet connector links your audio computer to the rest of the network via a standard GigE switch.
      Via your Ethernet port….
      Where ultra-low latency performance is less important, the Dante Virtual Soundcard (DVS) software can be used to host the network from your computer’s built-in Ethernet port. This provides latency figures equivalent to Focusrite’s professional FireWire interfaces. The virtual driver can also be used in small-scale portable system based around a laptop.
