Aton Model A275 Two-Channel Power Amplifier
Aton Model A275 Two-Channel Power Amplifier
Model A275 Two-Channel Power Amplifer is designed to drive multiple pairs of indoor or outdoor speakers from virtually any audio source. A typical installation consists of a home theater receiver zone 2 or zone 3 line level output feeding the A275. The A275 amplified outputs can drive speakers, volume controls, or DLA speaker selectors from ATON. The true test of any amplifier is the ability to drive multiple speakers at low impedance for hours on end. The Aton A275 does this extremely well. Heat is the number one cause for amplifier failure, or temporary audio loss from overheating. ATON designed the A275 amplifier with two long rows of external cooling fins to increase the heat dissipation. Higher cooling capacity equals longer product life and a cleaner audio signal.
