The dbx 1231 dual 31-band graphic equalizer is a high-precision audio tool for professional sound reinforcement, recording and installed AV systems.

With dual channels and 31 bands per channel, engineers can sculpt frequency response, manage room acoustics and optimise system performance with fine granularity. The unit’s straightforward, rugged controls and well-known dbx reliability make it a go-to for installations where tone, clarity and flexibility matter.

In corporate AV setups, fixed installations or touring rigs, this EQ ensures integrators can tune speaker systems, correct room response and deliver consistent audio across multiple zones.
