The Product

The dbx IEQ31 is a dual channel 31 band ⅓ octave graphic equaliser, designed and built to very high standards in a 3U rack mounting chassis, suitable for professional applications in the studio, on tour or in sound system installations. The heart of the design employs 24-bit digital signal processing with 48kHz sampling, which gives the advantage of very low distortion and outstanding sonic audio performance, but is wrapped up in a design which offers the user an analogue look and feel. The design incorporates advanced feedback suppression, type V noise reduction, and PlusPeak limiters which catch any unexpected signal spikes. With a frequency response of 10Hz to 22kHz and a dynamic range in excess of 113dB, this truly is a professional tool for the professional engineer.

Other features include switchable 40Hz/18dB octave low cut filters, selectable ±6dB or ±15dB gain ranges, balanced audio inputs and outputs presented on XLR, Euroblock and ¼" Jack connectors, LED output signal level meters and limiter gain reduction meters, and a system bypass switch. Mains power is applied via a standard 3 pole IEC connector.

The Manufacturer

dbx was founded in 1971 by David Blackmer who started his career working in professional recording studios. He developed a new process called linear decibel companding, a process considered at the time to be many times more effective than Dolby in reducing tape noise. Although the company went on to develop a range of signal processing equipment for use in recording studios, it was always best known for its noise reduction designs. After several mergers and acquisitions dbx is now owned by Harman International and continues to develop and manufacture a wide range of signal processing equipment which represent a solid build quality, a musical sound quality and excellent value for money.
