Overview

The D-Cell504 is an incredible mix of power and technology you wouldn't expect in such a small and lightweight amplifier: with 2x350W available at 4Ω, bridgeable to have 700W on a single 8Ω load with astonishing sound clarity, the D-Cell504 has already proven to be a wonderful solution for a very wider range of applications, from small-mid power professional loudspeakers to studio monitors, home cinema systems, musical instruments, powered mixers, and even hi-fi applications.

The D-Cell504 is made of two ultra-compact units – power supply and 2-Channel output stage – each one measuring just 100x78x45mm, guaranteeing easy mechanical integration and the ability to fit almost any possible design.

Limited size doesn't mean limited capabilities: the D-Cell504 power supply can drive two 2-Channel amp units, permitting multi-way configurations in a ridiculous amount of space. Both output channel pairs are bridgeable so that you can drive 3-way systems as well as 2-way bi-amped or symmetrical loads with higher power even at higher impedance.

Compactness and flexibility are the keywords even when looking at the DSP solution for the D-Cell504: in fact, the output stage is also available with an integrated 2in/4out DSP onboard, a powerful tool to shape the audio signal and to apply the dynamic processing needed to make the most of your speakers still keeping them safe.
