dbx 215s Graphic EQ

The dbx 215s is a dual-channel, 15-band graphic equalizer built for serious live sound and studio work. Its single-space rack footprint houses responsive 20mm nonconductive sliders with satisfying mechanical detents, making real-time EQ adjustments intuitive and repeatable. This is a workhorse tool for sound engineers and technicians who need transparent, surgical control over problem frequencies.

Audio Performance & Equalization

Each channel delivers ±12 dB input gain with a choice of ±6 dB or ±12 dB boost/cut range across all 15 bands, giving you precise control or aggressive shaping depending on your mix. The frequency response of 10Hz to 50kHz and 112 dB dynamic range ensure clean, transparent processing, while the switchable 12dB per octave low-cut filter (3dB down at 50Hz) handles rumble and subsonic content efficiently.

Design & Build Quality

Rack-mounted in a single 1U space with included mounting hardware, the unit features internal toroidal transformers for audio integrity and a universal 100-240VAC switch-mode power supply for worldwide deployment. Output level metering lets you monitor signal without guesswork, and the sliders' 1-inch throw with center detent makes returning to flat response quick and reliable.
