{"product_id":"dbx-dbx1231v","title":"dbx 1231 Dual-Channel 31-Band Graphic Equalizer","description":"\u003cp\u003eThe dbx 1231 is a two-channel, 31-band graphic equalizer with 1\/3-octave bands on ISO center frequencies. It is built for demanding sound reinforcement and installed systems, with straightforward controls in a 3U steel and aluminum chassis.\u003c\/p\u003e\u003cp\u003eThe 45 mm center-detent faders work over a selectable ±6 dB or ±15 dB range. Each channel has ±12 dB of input gain and a switchable 40 Hz low-cut filter. XLR, 1\/4 in. TRS and barrier strip connectors ease installation, and a chassis\/signal ground lift helps isolate hum. A hard-wired relay bypasses the unit when the power is off and waits 2 seconds after power-up before switching back in.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTwo channels of 31-band, 1\/3-octave equalization on ISO center frequencies\u003c\/li\u003e\n\u003cli\u003e45 mm center-detent faders\u003c\/li\u003e\n\u003cli\u003eSwitchable ±6 dB or ±15 dB boost\/cut range\u003c\/li\u003e\n\u003cli\u003e±12 dB input gain range\u003c\/li\u003e\n\u003cli\u003eSwitchable 40 Hz, 18 dB per octave Bessel low-cut filter\u003c\/li\u003e\n\u003cli\u003eElectronically balanced inputs and servo-balanced outputs\u003c\/li\u003e\n\u003cli\u003eRF-filtered inputs and outputs\u003c\/li\u003e\n\u003cli\u003eXLR, 1\/4 in.
