Description

A new, unused item with absolutely no signs of wear. Open box, but inside packaging with original protective wrapping. Not factory second. Full manufacturer’s warranty and free one year extended warranty from Gigasonic.

dbx 1231 is a dual channel, 31 band 1/3 octave graphic equalizer providing such standard features as dual channels of 31 – 1/3-octave bands, ISO frequency centers, +/-12dB of input gain range, and switchable 40Hz/18dB per octave low-cut filters. Other features on the 1231 Equalizer include 45mm faders, selectable +/-6dB or +/-15dB boost/cut range, XLR, barrier strip, and 1/4″ TRS connectors, balanced inputs and outputs, and chassis/signal ground lift for quick hum isolation.
