Product description

The Hammer 2 EQ Equalizer from A-Designs is a dual-mono, 3-band equalizer. Its filtering system passes musical 2nd order tube harmonics while eliminating unwanted noise. Hammer 2 EQ's overall frequency range covers 30 Hz to 40 kHz. Each channel features six detented rotary controls; three frequency selector knobs (Lo, Mid, Hi) which are stepped switches for easy recall, each with an accompanying gain knob providing continuously variable boost or cut of 12 dB. Each band has a selectable center frequency, and overlaps with the other bands in such a way that makes for a clean transition throughout the entire spectrum. Each channel also features individual toggle switches for EQ In/Out as well as Lo Cut (84 Hz) and Hi Cut (8 kHZ) filters that allow engineers to perform utilitarian EQ chores while still being able to bring the full power. Mainly intended as a broad stroke equalizer, the HM2EQ'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. Hammer 2 EQ Equalizer features tube-harmonic filtering circuit, a pair of 12AT7 tubes, and a custom heavy-duty toroidal power transformer. It also features a black, custom-milled, brushed faceplate sporting custom-milled aluminum control knobs, a heavy-duty Carling toggle power switch, and a big blue jewel power indicator lamp.
