DB TECHNOLOGIES - OPERA DIGITAL 405D 15" ACTIVE SPEAKER

dB's best-selling OPERA model now comes with 100 watts more power for even greater dynamic range. That makes it the model of choice for applications demanding punchy low end without an added subwoofer.

Bi-Amp
This spekaer is supplied with a high efficient BiAmp amplifier, one for the low and one for the high frequencies. This setup has many advantages the use of an active crossover instead of a passive one, an integrated audio controler for phase allignment and time correction and a limiter to protect the unit against damage.

Audiophile Performance

Power amps need a great deal of headroom to render natural audio events as authentically as possible. It takes a high-voltage power supply to provide this kind of headroom. digipro® delivers exceedingly high performance ranging up to 1000W/RMS, providing the dynamic range required for faithful, true-to-nature reproduction of every input signal. This power, paired with an ultra fast attack and truly realistic transient response, yields impressive audio performance that rivals that of very elaborate and expensive tube circuits. With a high pulse frequency of 500 KHz, this technology is able to deliver high-definition, high-fidelity audio signals with richly detailed yet natural-sounding top end.

SMPS
Ultra efficient switched mode power supplies (SMPS) with active power factor correction (PFC) provide all the juice amps need to deliver peak performance even when mains power quality is poor, for example, when low power feeds at live events cause voltages to dip. This makes SMPS far superior to conventional power supplies.

DSP: Digital Sound Processor
This models come with a powerful DSP. Serving as an active crossover and controller, it splits and limits 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 rendered accurately and articulately. And that makes an dBTechnlogies product a real all-rounder for every sound reinforcement challenge

Dual Active Limiter
Compact active enclosures are often driven at or near their limits for hours on
end. This series sports two unique limiter stages, one at the analog and the other at the digital level. They ensure exceptionally reliable performance and uniform response even at peak loads.
