Progressive New York-based audio technology firm Resident Audio has introduced the T4, "the first multichannel Thunderbolt audio interface which requires no external power," at $499.99 MAP. The T4 is a portable, 24-bit/96 kHz-ready four-channel I/O for Thunderbolt-equipped Mac and Windows with all required software drivers and a "Big Knob" master output control, XLR/TRS/TS inputs per channel, balanced TRS outputs per channel, main and secondary headphone outputs, universal phantom power, intuitive three-color LED-enhanced gain knobs for low-light operation, Input Mix control for blending live signal with computer playback, and "Smart Monitoring," which automatically switches between stereo and mono depending upon input configuration.
 
As Thunderbolt is twice as fast as USB 3.0, twenty times faster than USB 2.0 and twelve times faster than Firewire 800, the T4 provides near-zero latency.
