I wish that it had two more inputs, that way you could use the first two inputs for a pair of active 3-ways, and then use the other two remaining inputs for EQ'ing a pair of subwoofers.
This thing cost more than a MiniDsp with at least 4 inputs and 8 outputs. What advantages does the Bunker BPD-1 have over the MiniDsp with a similar feature set?
Marty you only need one set of full signal going into the bunker. You can then put an amplifier channel on each output and do exactly what you just said. I use the units to do 4 way stereo subwoofer, which is not possible, with the DBX units. or other units are far as I can see. The output are all truly independent of each other. I have not been back for a while, but I have the internal pics for everyone
So what you would have is Left and right Line level input, and 4 channel stereo output. With a total of 4 amplifiers needed to do all 8 outputs, or more if you bridge for the subwoofers.
Simply adjust high and low pass filters for each tweeter, midrange, and woofer, and then adjust for subwoofer crossover high and low pass.
Then of course you still have 5 band parametric eq per way, 33 band graphic eq per way, compressor limter per way, etc, as well as a subharmonic synth available.
However you just said active three way speakers. If you have an active three way speaker with single built in amplifier there is no way to do a three way active crossover for them. You would need to bypass the internal amplifier, and cut all the wires to your speakers. After which you could tri amp, and use the active crossovers in the bunker.
What you are probably thinking about with having four inputs is using two full signal inputs for left and right stereo,
and using two more for subwoofer use. You no longer would need 4 outputs running to 4 inputs to do this. You would just use two main outputs, and connect to the two inputs on the bunker. Then you would run two outputs from the bunker to the inputs on your main powered speakers, and 2 to main amplifier or subwoofer. In this case you could use the equalizer, parametric eq, sub synth, compressor limiter, etc on your main speakers through the first two outputs. (You would not be able to use individual crossovers for each speaker driver, ie tweeter, midrange, and woofer, but you could use the crossover to block output signal in the low end that you only want going to your subwoofers rather than your mains). The other two outputs you could hook up your subwoofers , and use the sub synth, parameteric equalizer etc on your subs to fine tune them how you wish. Each output has a full complement of these items, so it is like having four stereo equalizers, four stereo parametric equalizers , four stereo sub synth, and four stereo active crossovers etc. The old days would require a big stack of individual items to do this.
Many like me use the built in 3 to 5 band parametric equalizers per output, to augment low frequency bass in the 30 hz and under range, that tends to drop off in output in most smaller rooms. These parametrics equalizers are actually better at the task than subwoofer synth, at fine tuning your bass.
