The Zoom UAC-2 Audio Interface is a 2 channel bus powered audio converter that adds two channels of 24-bit/192kHz high resolution audio to any USB 2.0 or 3.0-equipped Windows or Mac computer. Featuring USB 3.0 SuperSpeed technology 4x upsampling and top-quality A/D and D/A converters the UAC-2 offers pristine ultra-low latency audio conversion for studio recording onstage playback of your audio files or high-fidelity streaming in your home or office. Step up to USB 3.0 SuperSpeed The USB 3.0 SuperSpeed transfer protocol supported by the UAC-2 is ten times faster than USB 2.0 and six times faster than FireWire 800. The result is low latency (2.2ms roundtrip @ 96kHz / 32 samples) for improved performance from your DAW software and a stable data stream that is unaffected by computer jitter (slight variations in timing) so theres no need to connect an external master clock source. Whats more the extra bus voltage carried by USB 3.0 (900 mA as opposed to the 500 mA carried by USB 2.0) allows for the use of higher-end electronic components such as the advanced preamps and converters in the UAC-2. Total Connectivity The UAC-2 is one of the most versatile interfaces ever. It works with everything from legacy USB 2.0 laptops and desktops all the way up to the latest-generation Mac or Windows USB 3.0-equipped computers. Or plug in an AC adapter and Apple Camera Connection kit or Lightning to USB Camera Adapter (sold separately) and use it with your iPad. AD / DA conversion The UAC-2 uses high-end components such as the Burr Brown PCM4202 analog-to-digital converter and AKM AK4396 digital-to-analog converter. In addition the UAC-2 performs 4-times upsampling during both analog-to-digital and digital-to-analog conversion. In other words when the sampling frequency is set to 44.1kHz or 48kHz the UAC-2 processes the signal at high resolution 176.4kHz or 192kHz. For A/D conversion this means less aliasing noise; for D/A conversion this means increased clarity and fidelity. The Ins and Outs The USB 3.0 connector on the rear panel carries digital signal to and from your computer in addition to providing power to the UAC-2 – no batteries or external power required. Dual front panel combo XLR/TRS inputs allow you to connect a wide variety of microphones as well as line-level signals from electronic keyboards and music players – even passive instruments such as electric guitars and basses. Dual balanced TRS output jacks enable you to connect the UAC-2 to amplifiers or self-powered speakers and theres an independent 1/4″ stereo headphone jack with dedicated volume control for private monitoring of the input or output signal. The UAC-2 is the first-in-class USB interface that performs 4-times upsampling during both analog-to-digital and digital-to-analog conversion (so that for example when the sampling frequency is set to 44.1kHz or 48kHz the signal is processed at high resolution 176.4kHz or 192kHz respectively). For A/D conversion this means less aliasing noise; for D/A conversion this means increased clarity and fidelity. Dedicated input gain controls and Clip LEDs make it easy to set optimum input levels and a large Output knob enables fast control over overall output level. A phantom power switch applies +48 volts to the mic inputs allowing you to use the UAC-2 with studio-quality condenser microphones and a three-way Direct Monitoring switch enables monitoring of input signal with zero latency in both mono and stereo. MIDI In and Out connectors allow interfacing with devices such as electronic keyboards and drum machines. Last but not least a Class Compliant Mode switch enables the UAC-2 to be connected to an iPad. (Requires optional power adapter and Apple Camera Connection kit sold separately.)
