Mackie Onyx Blackjack 2 x 2 USB Interface ($259.99 list, $200 street) www.mackie.com

October 1, 2010

MainGraphic_AWhat: Minimalist, compact, self-powered 2 x 2 USB interface, with Mackie Onyx mic preamps and excellent specs—all wrapped in a rugged metal enclosure suitable for the road.

Why: The average laptop’s audio capabilities are consumer grade, especially if said consumer doesn’t know what good audio sounds like—so you need a quality interface for recording on the go. Blackjack subscribes to the philosophy of “you don’t need a lot of features as long as the ones that are included do what you need.”

Faraway Factor: Photos of the Onyx Blackjack don’t prepare you for just how small it is—the front panel is 6-3/4" x 4". The rear panel is about 1-3/4" high (not including the front panel knobs, and a removable bar across the back that props the unit at a convenient angle). It’s not super-light due to the sturdy metal construction; if you dropped it hard the knobs might snap off, but the guts would likely survive just fine.

Strengths: Mackie’s Onyx preamps have a reputation for sound quality, and Blackjack offers two of them—as well as Cirrus Logic A/D/A converters with a quoted dynamic range spec of 114dB (A-weighted). The input jacks are Neutrik combo jacks, with front-panel switches to choose between line or hi-Z input for the 1/4" input; the gain runs up to +60dB on the mic in, and –15dB to +45dB for line/instrument ins. Phantom power is available, and unlike some older Mackie interfaces, delivers the full 48V (actually I tested 47.4—close enough!). There’s an input monitor (mono/stereo) for zero-latency monitoring, phone jack with level control, and separate left and right balanced/unbalanced 1/4" outs with their own monitor control. As to operating systems, you’re covered: Windows XP 32-bit, Vista/7 32- or 64-bit, and Mac OS X 10.4.11 – 10.6.4, including PPC processors back to the G4.

Tested with the RightMark Audio Analyzer, the swept sine wave frequency response is down 0.67dB at 20kHz, and essentially ruler-flat from 20Hz to 10kHz. The dynamic range and noise levels are actually better than quoted (see Figure 1), and crosstalk goes from a high of –65dB at 5Hz to a low of better than –95dB at 4kHz. Intermodulation + noise (swept frequencies) is below –84dB at all frequencies. Bottom line: The audio performance is excellent.

Limitations: There’s no MIDI I/O, which may or may not matter to you; given the size, I’m not sure where they would have put the jacks anyway. Phantom power is global, not per-input. Also, the Tracktion bundle that comes with Blackjack is the Basic Bundle, not the Project Bundle or Ultimate Bundle.

Conclusions: The obvious comparison is to the Saffire 6 USB, but there are some differences. They both top out at a 48kHz sample rate, but the Blackjack is smaller, while the Saffire includes both MIDI I/O and four DJ-friendly phono jack outs. Software-wise, Blackjack comes with the full version of Tracktion 3 and the Mackie suite of mixing and mastering tools, while Saffire 6 USB includes Ableton Live Lite 8 (arguably a more limited DAW than the full version of Tracktion) but also, a variety of loops and samples. Both units spec out as audiophile-quality, but the Onyx Blackjack’s angled panel scores big on ergonomics.

When size matters, the Onyx Blackjack is exemplary because it packs a lot into a very small package—and there’s no denying the audio quality. Onyx Blackjack proves that even when you gravitate to the portable/low end of a line, you’re still getting performance that runs circles around the very best interfaces of not too long ago.
