Crossover paints and response are continu-cus!y adjustable and individual output stages with ^de range gain controls will drive long cable runs and accurately match any power amplifiers. All of our 12dB Electronic Crossovers use state-variable filter circuits lo perform ttie frequency divisions. These filters provide simultaneous low-pass and high‘pass outputs. AH models include inveners on aiiemate outputs to keep everything in phase. A Variable Filter Response control is included for adfustmem of frequency response in the crossover region, allowing flat summing. The output stages have a wide range feedback level control circuit to maintain an optimum signal-to-noise ratio at any setting A special electronic power moniior for the ouipui stages prevenís turn-on transients without the use of relays. So!h inputs and ouiputs can be used as balanced or unbalanced and a peak overload circuit monitors all critical points in ftie circuit to insure low-distortion operation. The logical layoul of ihe conlro! panels provides an Intuitive, "easy-operation" teeL and LED's display peak information. Our entire line of electronic crossovers, like alt Ashly products, now features our exclusive five-year worry-free warranty.
