MACKIE ONYX BLACKJACK (DAC)
Inspired by the proven hardware design of our flagship Onyx-i Series mixers, the Onyx Blackjack Premium USB Audio Interface brings you studio quality sound and features via our flagship Onyx Mic Pres, Cirrus Logic® AD/DA converters, built-in DIs, phantom power and true analog hardware monitoring of inputs for hassle-free zero-latency tracking.
BOUTIQUE-QUALITY ONYX PREAMPS
Found on our most expensive studio consoles, Onyx pres are designed to meet or surpass expensive, esoteric standalone mic pres in terms of fidelity, headroom and transparency – as well as improved radio frequency (RFI) rejection and ultra-wide dynamic range. And with a full 60dB of available gain, would-be competitors are left in the dust.
HIGH-QUALITY AD/DA CONVERSION
The Onyx Blackjack uses Cirrus Logic®converters offering 114dB dynamic range (A-weighted) – a specification other companies sometimes charge thousands of dollars to achieve. Our preamp circuitry is aligned precisely with the onboard analog-to-digital conversion to always provide you with the most headroom and the lowest noise and distortion possible.
ZERO LATENCY RECORDING
Featuring a true analog monitoring path directly from the preamps to your studio monitors and headphones means you can track while listening in either mono or stereo to the direct analog source with zero routing. Not only that, it also means you can adjust your buffer settings to maximize your computer’s processing ability.
Both channels deliver 48V phantom power, so you can use studio-quality condenser mics with no problem. The studio monitor and headphone outputs have independent level controls for maximum flexibility. Plus, the Onyx Blackjack is bus-powered via USB, so there’s no power supply to lose or another cable cluttering your workspace. It also comes with Mackie’s Tracktion Music Production software, so you can get started recording right away.
NO DIRECT BOX NEEDED
Both channels double as built-in Dis which is perfect for direct connection of guitars, basses, keyboards, drum machines, etc. Having a built-in DI is great when you just want to plug in to record a quick riff or synth sound without the fuss of dealing with a traditional DI, and not having to carry a DI or two can make a big difference if you need to pack light.
Onyx Blackjack features a sleek, powder-coated all-metal chassis that is truly “Built-Like-A-Tank”and sits with a 25-degree inclination, allowing for full view of all controls at all times, meaning more recording time and less hassle.
