Mackie QuadEQ 4-Channel Digital Graphic Equalizer

Manufacturer's Description for Mackie QuadEQ 4-Channel Digital Graphic Equalizer

Four Channels of 30-Band Adaptive-Q Equalization
The Quad EQ employs four 30-band graphic, Adaptive-Q Equalizersan 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, super-accurate 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.

Even More Digital Advances
Of course, with the Quad EQ's ample processing power, we couldn't leave well enough alone. So we added 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.

*People are really attracted to sound engineers who know how to operate equipment with lots of flashing lights, so the Quad EQ was especially designed with plenty of lights in operation.

Series Overview
Developed in collaboration with Acuma Labs and SIA software, Mackie is proud to introduce the Quad Series24-bit rackmount processors that combine friendly, analog-style interfaces with the precision, convenience and reliability of next-generation digital processing. The Quad EQ and the Quad Comp/Gate start with no-compromise 24-bit circuitry, all-new digital algorithms, and the legendary ease-of-use which has become a Mackie hallmark. These processors offer instant storage and recall of frequently used scenarios, while their intelligent features and intuitive control panels make them 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.
