Focusrite TwinTrak Pro Dual Channel Strip

Focusrite TwinTrak Pro Dual Channel Strip
An affordable, high-specification dual mono/stereo tracking device, TwinTrak Pro also boasts comprehensive latency-free monitoring, unmatched digital connectivity, and all within a sturdy 2U 19" rack-mount chassis.

Each channel features Focusrite's award-winning Platinum pre amp, embellished with the option of instant 'air' and variable input impedance for improved microphone performance and extended creativity. A mid-scoop EQ follows, and provides variable frequency and depth of cut for vocal problem solving and miked-up cabinet ambience

TwinTrak Pro is equipped with a powerful dual mono/stereo optical compressor. This optical compressor features Focusrite's custom fast-acting optos, alongside side-chain inputs and the ability to operate as a true 'twinned' stereo pair. These circuit design innovations are complemented by a comprehensive set of focussed controls.

TwinTrak Pro is the first Platinum to feature a D/A converter as standard, alongside its optional analogue to digital converter. The D/A converter enables the user to feed mono or stereo digital signals into TwinTrak Pro. These signals can be fed either into the stereo latency-free monitoring section, or via line inputs (post- the pre amp stage) for further processing. The signal can then return to the digital audio workstation via Focusrite's established stereo A/D converter option.

Together, these facilities make TwinTrak Pro the perfect analogue interface for any digital audio workstation, and equally the world's first 'hardware plug-in'.

Features include:

• 2 award-winning Class A discrete transistor-based pre amps
• Dual mono/stereo optical compressor, featuring custom fast-acting optos
• Latency free monitoring with total control over balance, effects, mix and monitor levels
• 24 bit/192 kHz D/A fitted as standard, for processing digital signals or feeding digital signals into the monitoring path
• An optional 24 bit/96kHz A/D. Both the A/D and the D/A feature wordclock (BNC)
• Inductor-induced "Air" opens up high frequencies like an expensive transformer-balanced pre amp
• Variable impedance for improved microphone performance and extended creativity
• Mid scoop EQ for correcting problematic mid frequencies
• Direct inputs on the front fascia for both instruments (Jack) and microphones (XLR)
• Post pre amp inserts and compressor side-chain inserts, for enhanced processing flexibility
• 2 ocean blue peak-reading meters, innately beautiful and ideal for catching fast transients
