The power amplifier is the beast of burden —the final link in the electronics chain. Vast power reserves feed large output stages, which are controlled by a delicate input signal. The goal is to carve large and flawless copies of the input signal from a clean and effectively unlimited reservoir of power. These powerful output signals must control and command strict obedience from loudspeakers under constantly changing conditions. Perfection is both challenging and costly to achieve.
Our flagship Omega series amplifier designs are our best and most ambitious. They are used by Classé to probe the limits of sonic and technical performance, with cost as a secondary concern. For the first time in more moderately priced models, all Classé Delta series amplifiers feature Omega-inspired circuit topologies. From a company known for delivering exceptional value across a wide range of prices, these amplifiers represent the best price/performance offering ever from Classé.
Delta series amplifiers share important circuit blocks, adding to the performance benefits of using Classé amplifiers together in multichannel systems. Output channels are designed to be produced as 100W or 200W modules. The 200W modules are designed to be used in one-, two-, three-, and five-channel models. This efficient approach yields a consistency of performance across the entire range, allowing Classé amplifiers to deliver the highest quality results at less than stratospheric prices.
Delta series design features include balanced circuitry, overbuilt power supplies and oversized output stages to ensure the highest performance at every output level, with any loudspeaker. Enhanced protection circuits and intelligent power management add to the value and longevity of Delta series amplifiers while RS-232, IR and DC trigger controls make them well suited for any custom-installed or integrated system control applications.
