dB Technologies OPERA Digital 405D
Our 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
Features:
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.
DigiPRO Digital Amplifier
Power Densitiy
digipro® Class-D power amp technology packs huge performance and operating efficiency into a lightweight solution that leaves a very small footprint. With its remarkable 1:1 power-output-to-weight ratio, this technology brings highest performance capability to compact speaker systems. What’s more, it is also phenomenally easy to handle. digipro® - the high-End Powerpack.
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.
Full-fledged Class-D for Full-blown efficiency
In contrast to many other so-called “digital” power amps that merely run on a clocked switched-mode power supply, digipro® is a full-fledged Class-D power amp that operates on the principle of pulse width modulation (PWM). This technology is tremendously efficient with more than 90% yield. Components remain very cool because so little energy is lost in the form of heat. No fans are necessary. What’s more, components last longer and operate more reliably courtesy of the reduced thermal load.
Maximum performance
digipro® power amps come with highly advanced, ultra efficient switched mode power supplies (SMPS) with active power factor correction (PFC). They 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.
SMPS: Operates in the range of 95 V to 265 V Conditions power when line voltages fluctuate
Power and intelligence
digipro® technology synchronizes power stages and control circuits, creating an intelligent, responsive protection and supervision system. An integrated processor controls the ongoing interaction between the audio signal, switched-mode power supply, and PWM output stages, and processes key information concerning the status of the internal signal flow from the input to the speakers. digipro® monitors impedance and shuts down in case of short-circuit. Thermal limiters attenuate performance if the unit runs hot. Peak and RMS limiters protect speakers
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.
Asymmetrical Horn
Nowadays sound techs use line array systems to provide the best coverage for big events. The new dBTechnologies asymmetrical horn design delivers similarly effective coverage for smaller applications. The high-frequency horn is narrower on top to bundle sound and throw it over greater distances. It flares out at the bottom to achieve a wider pattern of throw. This compensates for decaying volume as sound travels further from the source and distributes the signal more uniformly across all audience areas.
Low Noise Reflex Ports
The new OPERA DIGITAL series’ enlarged bass reflex apertures are about more than merely stylish looks. They cut annoying wind noise by up to 50% and deliver enhanced, extremely tight and focused bass response
PP Housing
The polypropylene (PP) enclosures are designed and made in Italy to satisfy the most rigorous standards for quality. They look great, and their practical design is so very versatile that they may be used for various applications with professional rigging and installation accessories. Remarkably stable and rugged, they are perfect for mobile deployment. The slanted rear panels turn these cabs into handy floor monitors. And they are stackable for easy transport and storage
