Innovative 4-channel 30-band Digital Graphic EQ for Live Sound
Mackie's Quad EQ combines an analog-style interface with next-generation digital processing to give bands and FOH mixers a very handy live sound tool. This 24-bit rackmount processor offers instant storage and recall of frequently used scenarios, while intelligent features and intuitive control panels make the Quad EQ ideal for use in fast-paced live settings. Taken together, the Quad EQ and Quad Comp/Gate are powerful and road-ready additions to any serious live sound toolbox. Plus, you'll find Mackie's legendary ease-of-use alive and well in the Quad EQ.
Mackie Quad EQ at a Glance:
- Four channel, 30 band adaptive-Q equalization.
- Onboard Measurement Tools
- Store and recall EQ settings, and more.
Four Channels of 30-Band Adaptive-Q Equalization
The Quad EQ employs four 30-band graphic, Adaptive-Q Equalizers-an innovative design that provides equalization +/- 12dB using 30 individual EQ filters, without the ripple and gain-boosting artifacts found on traditional (Constant-Q) units. These Adaptive-Q filters and new, superaccurate LED display ladders paint a highly detailed picture of the Quad EQ's effect on the output signal. So in other words, what you see is what you get. Of course, if you're the type of person that likes to measure and analyze, you'd really want to get a mic and an RTA unit, which brings us to...
Onboard Measurement Tools
For the first time, sound-pressure level (SPL) and SMAART real-time analyzer (RTA) meters are no longer expensive add-ons, but part of a fully integrated, user-friendly package. The Quad EQ includes a bundled SIA reference mic, as well as a dedicated reference mic input. Once plugged in, SPL can be displayed via a bright 3-digit display in the upper right corner (at high SPLs, this meter also serves to warn you of oncoming police officers). Or simply press the Mic button and the built-in RTA will display what's going on in the room, on the same ultra-bright* ladders as the EQ filters. In this way, you can simultaneously view your EQ settings versus what the results are. And RTA data is post EQ, so if you encounter feedback, you can quickly see it, cut it, and view the results. Now that's progress.
Store and Recall EQ Settings
Of course, with the Quad EQ's ample processing power, Mackie couldn't leave well enough alone. The Quad EQ adds some features live sound folks will really appreciate: 99 user snapshots to store and recall your EQ settings; a built-in pink noise generator; variable Hi and Low pass filters with multiple slopes on all four channels; Stereo Linking of channels A/B and C/D; high-quality TRS and XLR input/output, and a Planet Earth power supply for use anywhere between 100 and 240v. . And for your most demanding audiences, the front panel boasts what Mackie calls a "Really impressive 'Light Show.'"

"In a two rackspace box, you get four complete channels of 31-band graphic EQ along with a real time analyzer (mic included) that's easy to use and sounds great. It is so much better having the bright LED displays spread out across the front panel in a live sound environment, instead of messing with row after row of tiny sliders while trying to set up the EQs for the mains and the monitors."

"This is a dream come true for live guys! Four channels and tons of presets in a clean, lean and pristine sounding EQ. Where was it when I was struggling with massive racks of analog graphic EQs that were scratchy and/or noisy? (Can't wait for the 8-channel version in a single rack space with a remote/display so I'll get a Quad EQ now!)"
