Wanted an external PEQ with RCA inputs and outputs for my subwoofer. I was c. to provided the required miniDSP gain boost without also introducing noticeable noise.

I have spent $75 on the UMIK-1, $105 on the miniDSP 2x4, $60 for the TC-780LC preamp, and $130 for the 124A preamp without an acceptable solution.

Bottom line is don't waste your money on the miniDSP 2x4 as its very low post PEQ output makes its basically useless unless your subwoofer's amplifier has a lot of gain to spare.

Extremely good value and quite solidly made.\r\nVery well thought out product that outguns traditional active crossovers and filters for a fraction of the price.\r\nSound quality is very good.
