What is it?A 24-bit/96kHz USB audio interface offering dual mic preamps. DetailsFast Track Pro incorporates dual front-panel mic/line inputs and provides phantom power for condenser microphones, inserts for outboard effects, balanced and unbalanced analogue outputs plus S/PDIF digital I/O. The design offers near-zero latency direct hardware monitoring plus an A/B source switch, dual output pairs (for ‘DJ-style’ cueing) and a built-in headphone amp with volume control. Hardware direct monitoring eliminates the latency or delay inherent in internal circuitry while monitoring an input signal and existing tracks. It’s also possible to listen to an input complete with effects while recording by using M-Audio’s low-latency ASIO monitoring. Optional driver software is available offering total routing control over the 4 x 4 I/O – including setting up an effects loop with external devices. Mic inputs on Fast Track Pro benefit from a 20Hz – 20kHz frequency response (+/- 0.1dB), -101dB SNR and 0.005% THD.
