Focusrite RED 4Pre Audio Interface with Thunderbolt 2, Pro Tools, Dante Connections

ออดิโออินเตอร์เฟส Focusrite RED 4Pre, 56 Inputs / 64 Outputs, 24-Bit / 192 kHz Sampling, Four Red Evolution Microphone Preamps, Digitally Controlled Preamps, Includes Focusrite Control Software, Red and Softube Plug-Ins 

The Red 4Pre from Focusrite is a 58-input/64-output, high-resolution audio interface with Thunderbolt 2, Pro Tools | HD, and Dante connectivity. The interface offers four Red Evolution microphone preamps, with -129 dBu of EIN and 63 dB of gain providing low noise floors with significant headroom, and includes the “Air” effect, which recreates the sound of transformer-based mic pres from the ISA range.

All features of the preamps can be controlled from the front panel or from the included Focusrite Control software. In addition to housing the control surface, the front panel also features three color displays, two ‘extended-headroom’ 1/4″ instrument inputs, and two 1/4″ headphone outputs with independent level controls.

The rear panel offers a wide selection of analog connectivity, including 4 XLR microphone inputs, 8 line level inputs via a DB25 connector, 8 line level outputs via a DB25 connector, and a pair of 1/4″ monitor outputs. For digital connectivity, the interface offers two sets of optical in/out TOSLINK ports, as well as stereo S/PDIF I/O via RCA jacks.

Two DigiLink connectors provide compatibility with Pro Tools | HD interfaces, while the two Thunderbolt 2 ports connect directly to a Mac computer. The two Dante Ethernet ports support audio-over-IP networking for an additional 64 channels. The Red 4Pre also offers both Wordclock and Loop Sync I/O, for connecting any additional digital gear via the BNC connectors.

The Red 4Pre also includes the Softube Time and Tone bundle featuring four plug-ins including Drawmer S73 Intelligent Master Processor, TSAR-1R Reverb, Tube Delay, and Saturation Knob. Also included is the Red Plug-In Suite, which contains accurate models of Focusrite’s Red 2 EQ and Red 3 Compressor hardware. The Red 4Pre ships with a 6.6′ / 2.0m Thunderbolt cable, an IEC power cord, and software activation codes.
