- Digital signal processing
One of the best ways to get superior sound 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. Infinity’s incredibly small DSP4425 four-channel amplifier and processor will do both, providing four channels of 25 watts RMS (more than twice the power of a typical factory radio) while sculpting the sound with powerful tuning software using your Windows PC.
- Connecting to the whole system
Infinity designed the DSP4425 to take the signals meant for your vehicle’s front and rear speakers, process those signals to create four finely-tuned and powered outputs, and then send them on to your speakers. You can also use this DSP/amp to power front tweeters and midrange drivers, if you’re building a front-stage-only sound system.
- Bass expansion
The DSP4425 features a pair of full-range preamp outputs, channels 5 and 6, that can be used to send signals to a subwoofer amp’s inputs. An optional remote control works with these channels serving as a bass level controller.
- Tuning
Every powered 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; 0/180° phase adjustment; plus a lot more. You can assign each input to an output, as well as sum different input signals in order to create a full-range signal to be processed.
