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 in. phone plug making the units readily interfaceable to any system. Dual channel units may be used as a stereo equalizer or as 2 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.
The SR431 QXLR is a single rack space, 31-band 1/3 octave graphic equalizer. Its fully shielded internal transformer provides extremely quiet operation. and like all of the SR line of equalizers, it has constant Q filters.
