This little unit features 2 XLR/TRS combo inputs with phantom power, 2 RCA inputs, 4 Balanced +4dBu outputs, and optical S/PDIF I/O with up to 24-bit/192kHz playback and recording quality! Like the UA-25, the FA-66 also includes a built-in limiter making it an excellent unit for remote recording where a clean audio recording is a must and a second take is not an option. The FA-66 offers extremely low latency through CoreAudio WDM and ASIO 2.0 drivers, as well as direct monitoring so you can listen to your audio as it’s being recorded.
