Fluid Audio SRI-2 USB Audio Interface



Featuring a robust aluminum chassis, the SRI-2 interface is a sturdy piece of gear reminiscent of the “old school” studios.  Along with the striking design comes exceptional 21st century audio quality and functionality.  Best-in-class digital converters capture the detailed nuance of every recording.  The large volume knob provides accurate control of the output level, and direct monitoring provides zero-latency tracking.  The 2 XLR/TRS combo inputs are conveniently mounted on the front of the SRI-2, so you can easily plug in your instrument or mic.  The truly unique innovation of the SRI-2, however, is the speaker switching capability, which allows you to A-B your mix on two sets of speakers (with one of them hopefully being from Fluid Audio).

Big Volume Knob
Easy to reach on the top surface, the knob is solid aluminum with rubber grip for good weight and feel

Two combo XLR/TRS inputs are front mounted for easy access. High quality pre-amps insure crystal clear signal path.
Low noise mic pre-amps support 48V phantom power.

Inputs, buttons and knobs are placed conveniently on the top surface of the SRI-2. No need to to look down to see what is engaged..
All is clearly in view while recording. LED indicators on all buttons and knobs able you to monitor yours settings even in dimly lit studios.

Ample Power from Headphone output
