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.
Longer throw faders provide more precise adjustments when equalizing a room. The SR830QXLR offers 2 channels of equalization each with 15 bands of 45mm faders. The all steel chassis construction can handle the abuse of the road, or the solace of a permanent installation.
The SR831QXLR is a 1/3 octave, 31-band, constant Q equalizer housed in a two rack space, all steel chassis. It includes a shielded internal power supply, balanced XLR input/outputs, as well as balanced 1/4 in. inputs and impedance balanced 1/4 in. outputs.
