For their furnish division and bonus points, Crownâs new XLS Series of amplifiers make available an unprecedented steady of about, configuration malleability, and purchaser-brotherly features. The following points summarize key technology breakthroughs and refinements behind these benefits.
Integrated Digital Crossover and Limiter
Most amplifiers in this retail group stipulate narrow facilities, if any, for input signal filtering and driver preservation. (Conventional offerings are uncomplicated analog dear-behind the times filters and a limiter, generally speaking selected via educate-panel DIP switches.) In set off, the new XLS Series utilizes lofty-unshakeability digital signal processing to put into effect a obedient PureBand⢠Crossover System and proprietary PeakX⢠driver haven limiting.
Using the informal-to-look over front panel LCD grandeur and obese r buttons, users can preferred crossover points from 50 Hz to 3 kHz on 1/12 octave centers, allowing faithful identical of specified crossover points on most bi-amplified loudspeakers. Filters are fourth-non-sequential Linkwitz-Riley, with stiff slopes for seamless transmutation between lofty and low drivers. Alternatively, the digital filters may be set to optimize both amplifier channels for driving either stoned- or low-frequency loads, or for driving full-sort systems.
The PeakX limiters utilize authoritatively able yet sonically sheer algorithms derived from the OmniDrive HD loudspeaker stab processing in Crownâs flagship I-Tech HD Series. By spot on equivalent comeback to the achieve characteristics of each amplifier, PeakX enables significantly higher production levels than are attainable with commonplace analog limiting, yet with assured driver safe keeping. The front panel liberal-be in the same league buttons also first-rate limiter on/off (per conduit) as well as go-fashion on/off. There are no tokus-panel DIP switches.
Advanced Switched-course Power Provisioning
A quite unwasteful switching power satisfy is optimized for upper limit power give from the AC pen-mark through the Elegance D output station to the loudspeakers. Compared to older, 60Hz transformer-based power supplies, a side allowances is sizeable persuasiveness reduction: all models weigh less than 12 pounds, but with no compromise of Crownâs traditionally sinewy develop prominence.
