Digipro® G2

System of digital amplification engineered by dBTechnologies.
Based on the previous Digipro project, the newest G2 versions' efficiency has been improved by cutting down on consumption and heating.
The introduction of a 'new avant-garde' component, a better s/n relation and a lighter weight, confer a superior dynamism to the new Digipro G2 digital speakers.

DSP: Digital Sound Processor

These models come with a powerful DSP. Serving as an active crossover and controller, it splits and limits the signal and aligns phases and delay times.
Best of all, it even enables dBTechnologies' engineers to fine-tune the enclosures for the most balanced response.
It is this perfect balance that ensures your signals - speech, playback tracks, and live music – are sent accurately in every detail.
That makes a dBTechnlogies product a real all-rounder for every sound reinforcement challenge.
