The Resident Audio T4 is the first ever four-channel Thunderbolt™ audio interface which requires no external power—a breakthrough in the worlds of live performance and recording. It adds four channels of I/O to Thunderbolt-equipped Mac and Windows computers*, with support for high-resolution 24-bit/96kHz audio and near-zero latency for virtually instantaneous recording and playback.

The lightweight and portable T4 comes with all required software drivers and a ton of innovative features such as an auto-detecting Multichannel Output Mode and Smart Monitoring, which automatically switches between stereo and mono depending upon input configuration. Four combo XLR / ¼" input jacks allow you to plug in microphones, instruments and line-level devices— with phantom power for all inputs—and there are four balanced TRS outputs for connection to speakers and external mixers. MIDI connectors enable the T4 to be used as an ultra-stable MIDI interface, and there are even dual headphone outputs. Tilted tactile gain controls with three-color wraparound LEDs allow you to quickly set optimal levels, even in low-light onstage environments.

Whether you're in the studio, on the stage or in the DJ booth, the T4 provides the perfect interface between your computer and your performance.

INPUTS AND OUTPUTS
The T4 provides four combo XLR / ¼" inputs, switchable between Mic, Line or Instrument level, complete with phantom power. In addition, there's a dedicated stereo headphone output and four ¼" TRS balanced outputs, one of which can be used as a secondary stereo headphone output. Last but not least, MIDI in/out connectors allow you to use the T4 as a MIDI interface with an ultra-stable clock that keeps all your sequencers and drum machines perfectly locked to audio playback.

In live performance, the T4 effectively turns your computer into an instrument with multiple outputs—great for electronic musicians and DJs. In the studio, you can selectively route audio to different mixer channels and outboard signal processors to create complex effects.

CONTROLS
Each T4 channel has a dedicated input gain knob and a three-color wraparound LED signal indicator, allowing you to easily set optimal levels even in low-light onstage environments. In addition, an Input Mix control (with its own three-color wraparound LED) enables you to set the perfect blend of input signal with the output signal coming from your computer, and a Big Knob volume control sets the level of connected headphones as well as the overall monitoring level.*

Each pair of T4 channels also has a dedicated INST/LINE switch. This is used to set the inputs to instrument-level or line-level and also determines the Smart Monitoring setting.

* Stereo Mix mode only; in Multichannel mode, the Big Knob controls headphone level only.

OPERATING MODES
The T4 operates in one of two different modes, depending upon output configuration.

MULTICHANNEL MODE
When a connection is made to Output jack 4, the T4 operates in Multichannel mode, with four discrete monophonic output signals from your computer routed to the corresponding four Output jacks. In Multichannel mode, live input signal is sent to the headphone jack only.

STEREO MIX MODE
When no connection is made to Output jack 4, the T4 operates in Stereo Mix mode. In this mode, all live input signal, along with all output signal from your computer, is internally mixed to stereo and is routed to Outputs 1 and 2. In Stereo Mix mode, you can use Output 3 as a second headphone jack.

SMART MONITORING
The T4's unique Smart Monitoring feature allows you to switch between stereo and mono monitoring, depending upon input configuration. Monophonic monitoring allows you to remove one set of cans and still hear the sound of everything in one ear—great for vocalists and DJs.
