  • crossover from gizmo?

    Would it be possible to develop an inexpensive stereo crossover unit from the Gizmo circuitry?

    It might be nice to go along with stereo Scamps - split the signal before external amp/Scamp amps.

    That's a great idea! I am currently using av123 MFW-15's in stereo with a Behringer DCX2496 to split the stereo signal. You could have a left/right crossover and sub output. If you only had one sub, you could just get a Y cable to combine the outputs. The Y cable should actually be included. This should help sell more subs, too.

      What would it do? Would it be a high pass or low pass x-over? If it is a low pass, why would it be better than what you would get from the scamp's onboard x-over?

        Key word would be stereo. Separate output signals for L and R channels. Something like this:

        But simpler, cheaper, and as always, better sound quality if possible.

          Use two Gizmos for dual mono preamps. Then you have a stereo sub crossover. Just set the volume to the same setting on each unit. :)

            Ah, but then you need two power cords. And if you already have a preamp/amp - you might not have a need for a gizmo let alone 2. Plus, I think a stereo crossover might be built for a lot cheaper than 2 gizmos.

            I don't know, probably wouldn't be a high volume unit, but there isn't much comparable on the market.

              Trying to understand what is being suggested here. Isn't this what the Behringer DCX2496 can do? These go for under $100 very easily and would seem to be able to do what the OP wants. Am I missing something?

                If you are finding DCX2496 for under $100 that is a very good deal. They are very flexible units for two way or three way XO's. They are also balanced output so you need the XLR-RCA adapters for connection to most consumer audio gear.

                For what I paid for a DCX2496, two Gizmo's are cheaper. This gives a fixed 100Hz crossover frequency for the subs. A pair in dual mono operation would give outputs for stereo subs. Just use one channel and sub out from each Gizmo. :huge:
