Zoom UAC-8
There’s a whole new world of possibilities for Mac and PC Creators — high-speed, high-resolution, and low-latency. Upgrade your rig with the rackmountable UAC-8, and add 18 inputs and 20 outputs to your USB 3.0-equipped Mac or Windows computer—even your iPad.* Plug in a microphone, line-level device, or instrument and start bringing your ideas to life, or take the UAC-8 onstage to enable high-res audio playback, all the way up to 24-bit/192 kHz.
USB 3.0 SuperSpeed:
The USB 3.0 SuperSpeed transfer protocol used by the UAC-8, with a speed of 2.0 ms roundtrip @ 96 kHz / 32 samples, is ten times faster than USB 2.0 and six times faster than FireWire 800. That not only ensures low latency, it provides a data stream that's unaffected by computer jitter (slight variations in timing), so there's no need to connect an external master clock source.
The Hardware:
INPUTS: The UAC-8 provides a wide variety of both analog and digital connectors. 8 front panel combo XLR/TRS inputs accept mic- and line-level signals, and you can even plug instruments directly into Inputs 1 and 2. Dedicated input gain controls and Clip LEDs make it easy to set optimum input levels, and a Phantom Power switch enables the use of condenser microphones.
OUTPUTS:
The UAC-8 has dual balanced analog TRS output jacks for connection to monitors, and there are also 8 discrete balanced TRS analog line outputs for multichannel monitoring or connection to external effects devices. A large front-panel Output knob offers fast control over output level, and there are two independent ?" stereo headphone jacks, each with its own dedicated volume control, for private monitoring.
DIGITAL I/O:
8 ADAT and stereo S/PDIF digital inputs/outputs allow for the connection of up to 10 external channels, and built-in Word Clock enables easy integration into any system. In addition, MIDI In and Out is provided to allow interfacing with devices such as electronic keyboards and drum machines.
Main Features:
* 18‐in/20‐out USB 3.0 SuperSpeed audio interface
* Standalone mode allows use as an 8-channel mic preamp and A/D or D/A converter without connection to a computer
* Support for recording and playback of up to 24‐bit/192 kHz high‐resolution audio
* Low latency audio streaming
* 8 combo balanced XLR/TRS analog input connectors accept both mic and line‐level signal
* High‐performance mic preamps with up to +60dB of amplification
* Hi‐Z switches allow direct connection of electric guitar or bass (INPUT1, INPUT2)
* Independent gain controls and clip LEDs for each input
* Switchable +48 V phantom power (INPUTS 1‐4, INPUTS 5‐8)
* 10 balanced TRS output jacks for connection to mixers, amplifiers, self‐powered speakers, headphones, or effects devices
* Dual front-panel 1/4" headphone outputs with dedicated volume controls
* Large knob output volume control
* 4x upsampling during A/D and D/A conversion for reduced noise and enhanced fidelity
* Asynchronous transfer system unaffected by computer jitter
* S/PDIF IN/OUT: 2IN / 2OUT, up to 24‐bit/192 kHz
* ADAT Optical IN/OUT: 2 IN / 2 OUT at 192/176.4 kHz (S/MUX4 compatible), 4 IN/4 OUT at 96/88.2 kHz (S/MUX compatible), 8 IN / 8 OUT at 48/44.1 kHz
* Word Clock in/out
