Boutique EQ for demanding studio applications.

A-Designs Audio’s HM2EQ HAMMER, a three-band, dual-mono tube/hybrid equalizer, has been widely praised for its sound in the studio, both for tracking as well as across the main mix outputs. After fielding input from many engineers and producers, A-Designs announces a new version, the HAMMER 2.

Now with extended frequencies as well as added shelving on the lows and highs, the frequency bands can now nicely overlap into each other so you can really give the bottom end more punch. Continuous-sweep pots have been replaced with 31-detente controls, which improve setting repeatability. With the new HAMMER 2, musicians and engineers can recreate the same sounds they’ve loved with the previous model, but now have access to even more options and tones.

A-Designs’ world-class HAMMER 2 is one of a select few audio tools that enhances sound simply by running signal through it, thanks in part to an ingenious filtering system that passes musical, second-order tube harmonics while eliminating unwanted noise—the perfect “heating blanket” for any DAW.

Each channel features six detented rotary controls: three frequency selector knobs (Lo, Mid, Hi), stepped switches for easy recall, each with an accompanying gain knob providing continuously variable boost or cut of 12dB. Each band has a selectable center frequency and overlaps with the other bands in such a way that makes for a seamless transition throughout the entire spectrum.

Both channels also feature individual toggle switches for EQ In/Out as well as Lo Cut (84Hz) and Hi Cut (8kHZ), filters that allow engineers to perform utilitarian EQ chores while still being able to bring the full power of the HAMMER 2's three bands to bear. Mainly intended as a "broad stroke" equalizer, the product’s bandwidth (Q) is self-adjusting (floating), based on a combination of the amount of gain applied and the dynamics and frequency content of the program material.

Its ability to have its Q "move with the music" is one the keys to its incredible musical performance and another reason why it's practically impossible to make signals sound bad at any frequency or gain setting. Along with its innovative tube-harmonic filtering circuit, a pair of carefully selected 12AT7 tubes—offering the most consistent control of any tube—and a custom, heavy-duty toroidal power transformer add the final touches to the HAMMER 2’s signal path.

It has a black, custom-milled, brushed 2U faceplate with custom-milled aluminum control knobs, a heavy-duty Carling toggle power switch, and a big blue jewel power indicator lamp—overall, a stunning combination of “modern-retro” looks that jump out of the rack.
