DOD SR231QXVLR Dual 31 Band 2 Sp EQ 20mm Faders

DOD's flagship equalizer, the SR231 QXLR combines two constant Q, 31-band, 1/3 octave equalizers into a two rack space steel chassis. The back panel boasts XLR, and 1/4 inch connectors. With a fully shielded internal power supply, and unsurpassed specifications, the SR231QXLR is the perfect choice where ever stereo, or dual equalizers are needed.

DOD EQs are versatile, cost-effective equalization tools for musicians, studio engineers, and live performers. The units offer up to 12 dB of cut or boost per band with a switchable low cut filter for each channel. Electronic switching of these functions minimizes pops or clicks when the switch is depressed, and up to +/-12 dB of level control is available. This feature makes A/B comparisons of the EQ'd signal to the original signal quick and easy. Connection may be either balanced with an XLR connector or with an unbalanced 1/4" phone plug making the units readily interfaceable to any system. Dual channel units may be used as a stereo equalizer or as two independent equalizers. The units offer either 1/3rd octave or 2/3rds octave resolution, depending on the unit chosen. All DOD equalizers are solidly built with steel chassis and CSA standard circuit boards for years of reliable service.
