Bryston 21B³ effektforsterker

Ta kontakt for pris

Bryston 21B³ tre-kanals effektforsterker ble utviklet for å levere forsterkning til Bryston sine aktive 3-veis høyttalersystemer. Bryston 21B³ er en kombinasjon av 7B³ eg en 4B³ effektforsterkers, som gir massevis av krefter til en aktiv delt høyttaler. To av disse i et aktivt delt system gir en dynamikk og klarhet som tar pusten fra deg.

Beskrivelse

 

The Bryston 21B³ three channel amplifier was crafted to provide superb amplification for your Bryston Active Loudspeaker System. The Bryston 21B³ is essentially composed of a 7B³ and a 4B³ amplifier, which provides plenty of power for a single active loudspeaker. Two of these amplifiers will drive your active system with breath-taking ease and clarity.

Fully active loudspeaker systems dispense with passive crossovers found in conventional loudspeakers in favor of inserting the crossovers before the amplifier. The benefits include increased flexibility of filter shapes, the ability to make fine-grained adjustments resulting in improved on and off axis response (these are often competing objectives in passive loudspeakers), direct coupling of the loudspeaker to the driver (avoiding losses inherent in passive crossovers), and higher SLP with lower distortion. The Bryston Active Loudspeaker System combines decades of research into acoustics, electronics, amplification, and state of the art components to recreate your recordings with stunning realism.
