Designed for audiophiles seeking precise, powerful in-car audio tuning. ## Description Digital signal processing for the win One of the best ways to get superior sound fidelity in your car is to add an amplifier to pump up the power, along with a digital signal processor to fine-tune the sound quality. JBL's incredibly compact DSP4086 8-channel amp/processor will do both, providing eight channels of 40 watts RMS while sculpting the sound with powerful tuning software using your Windows PC. Connecting to the whole system The DSP4086 was designed to take the signals from your vehicle's front speakers, rear speakers, front center channel, and rear subwoofer. You can then process those signals to create eight powered outputs, and you have the ability to power and control your front tweeters. Tuning Every channel features 31-band EQ, switchable from parametric to graphic; completely variable high-, low-, and band-pass filters with selectable slopes; time delay, up to 12ms in 0.2ms increments; and 0/180 degrees phase adjustment. You can assign each input to an output, and you can sum signals in order to create a full-range signal to be processed.
