DA7.2 offers 750 watts at 8Ω stereo. Each channel works at 2Ω to satisfy all requirements.
DA7.2 series adopts Audiocenter latest Class H+ circuitry to eliminate the Class H cross switching distortion.
DA7.2 series is the best choice for the audiophiles. Audiocenter won’t make any compromise on the sound quality of professional amplifiers. DA7.2 adopts carefully designed linear power supply system and toroidal transformer, selected components like audiophile Wima capacitors, Rubycon capacitors, Onsemi transistors, Neutrik® connectors and Belden audio wires, etc. High quality materials and technology ensure clear and clean sound with a high damping factor. This makes DA7.2 series suitable for any kind of application, from high power loudspeakers to critical monitoring where crystal clear highs are mandatory. It is widely used in concert, stadium, odeum, entertainment center, theater, etc.
- A-Guard Protection System
A-Guard is Audiocenter comprehensive protection system which includes optimized limiter circuit. Unlike other solutions which depend on separate circuits to address different problems, A-Guard was developed as centralized solution where all protection requirements work together in perfect harmony. A-Guard is only applied when it’s necessary to protect the amplifier. This is the reason why DA amplifiers are able to sustain full power output even under complex capacitive loads.
- Smart Overheat Management
The smart overheat management of DA series adopts unique circuitry to monitor the amplifier’s temperature in real time. When the safe operation of the amplifier is compromised, the output power is reduced but not shut down, which ensures the system can work stably in high temperature environment.
- Class H+ Circuit Design Eliminates Cross Switching Distortion
DA series adopts Audiocenter latest Class H+ circuit to eliminate the Class H cross switching distortion. The result is the same low distortion as Class AB. All DA amplifiers have less than 0.02%THD at 16KHz and the sound is so clean and natural.
