Each channel of the TwinTrak Pro features Focusrite's award-winning Platinum preamp, 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.

A Focusrite favorite is TwinTrak Pro's 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 on the TwinTrak Pro by a comprehensive set of focussed controls.

TwinTrak Pro is the first Platinum Series processor 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 (after the preamp stage) for further processing. The signal can then return to the digital audio workstation via Focusrite's established stereo A/D converter option.
