Resident Audio has made available their T4 multichannel Thunderbolt audio interface that will not require any kind of external power, which is a good place as any to start. After all, this portable T4 would be able to introduce a quartet of audio I/O channels to Thunderbolt-equipped Mac and Windows computers, and can be integrated easily into any live performance rig or home studio without batting an eyelid.
To make sure that you will be able to get started right out of the box, it will arrive with all of the necessary required software drivers as well as delivers a range of innovative features, including a “Big Knob” master output control, an Input Mix control for blending live signal with computer playback, and Smart Monitoring, where that will be able to switch between stereo and mono automatically, depending upon input configuration.
The T4 would support 24-bit/96kHz audio with near-zero latency for virtually instantaneous recording and playback, where four combo XLR / TRS / TS inputs are provided for the connection of microphones, instruments and line-level devices. The asking price? $499 a pop.
