TT Pro is the first Platinum to feature a D-A converter as standard, alongside its optional A-D converter. The D-A converter enables the user to feed mono or stereo digital signals into TT 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 as a ‘hardware plug-in’. The signal can then return to the digital audio workstation via Focusrite’s optional stereo 24bit/96kHz A-D converter. The converter is 24 bit and 128 x over-sampled, handling sample rates of up to 96kHz, with S/PDIF output and a BNC word clock connector. An ADC lock LED on the front panel shows when Word Clock sync has been established, whilst two DAC input LED’s show when signal is flowing through the D-A converter. Together, these facilities make TT Pro an ideal tracking device, the perfect analogue interface for any digital audio workstation, and equally the world’s first ’hardware plug-in’.
