Power Amps Anchor Classe Audioís New Delta Range

19-Aug-04

Five new power amplifiers from internationally respected high-end audio maker ClassÈ Audio anchor the new Delta family, which marks the most important introduction in the Canadian firmís near quarter-century history. The five Delta amps encompass stereo, multichannel, and monaural models, each featuring the tremendous current reserves and astonishing transparency and finesse that have made ClassÈ amplifiers famous among serious audiophiles the world around. And each model is designed to match other components in the exciting new Delta family, which combines elegant, highly integrated industrial design with an industry-leading new touchscreen-based user interface. The ClassÈ Delta series amplifier range is comprised of the 100-watt stereo CA-2100 and 200-watt stereo CA-2200, two multichannel designs, the 3x200-watt CA-3200 and 5x200 CA-5200, and a single monaural model, CA-M400 of 400 watts. The five amps share substantially similar building blocks, differing primarily in channel-count and power-level.  Consequently, they also share important design and performance characteristics, beginning with the colossally stable power supplies and massive current capability for which ClassÈ amplifiers have long been known. Thus, while the above power-ratings all refer to use with 8 Ohm loads, each of the Delta amplifiers delivers considerably more power into lower impedance loudspeakers. All five new ClassÈ models also furnish both balanced (XLR) and single-ended (RCA) inputs for all channels, ensuring maximum dynamic-range potential with any connection scheme, most especially with the new and forthcoming touchscreen-based preamplifier and preamp/processors. And the five amplifiers all incorporate power/standby switching controllable via DC-trigger, IR-signaling, or RS-232 control, ensuring complete system integration regardless of configuration.Most importantly, however, the new Delta-family amplifiers feature circuit topologies and components derived from ClassÈís Omega-series amplifiers, widely recognized as a world-standard in amplification. Elements such as fully balanced circuit design, massive, ultra-stable, low-noise power-supplies, and meticulously selected and matched output devices ensure the dramatic power and delicate detail and dynamic finesse expected of ClassÈ amplifiers. To maintain their superb sonics in all conditions, the new models also feature the most carefully ìmanagedî amplifier designs yet devised. Newly developed monitoring circuits constantly observe such parameters as incoming AC voltage and polarity, ground condition, output current, DC offset and heatsink and ambient chassis temperatures, assuring safe, reliable operation without any sonics-compromising protection circuitry whatsoever (or even the sonically intrusive expedient of fusing): If a potentially dangerous condition such as over-voltage or a speaker-leads short is perceived, the ClassÈ amplifiers simply shut down, alerting the owner. And since all of the amplifiersí monitoring elements lie entirely outside of all signal paths, the net musical effect of these safety nets is precisely zero.Also common to the new Delta-line amplifiers is ClassÈís stunning new industrial design, developed by Morten Warrenís famed Native Design group. This features a dramatically radiused, sculpted-metal fascia and common chassis-width that encourage every Delta system combination to merge into a smoothly integrated visual whole. With its combination of stereo, multichannel, and monaural models, the ClassÈ Delta series power amplifiers stand ready to serve the finest music and home theater systems in any configuration and any number of channels. The ClassÈ Delta series amplifiers are available in North America at the following manufacturerís suggested US prices.Model CA-2100 2x100 watts $3,500CA-2200 2x200 watts $5,000CA-3200 3x200 watts $6,000CA-5200 5x200 watts $8,000CA-M400 1x400 watts $5,000For more information, please visit www.classeaudio.com.
