STARKE SOUND

A7-450(Discontinued)

A7-450

7 Channel Power Amplifier

450 Watts Per channel

 

For years home cinema amplifiers have possessed powerful capabilities but all too often fall victim to producing an over amplified sound that is less than ideal. Once again, Starke Sound has taken the challenge to change the standard. The A7-450 is capable of up to 225W output per channel into 8 Ohms (which doubles  power into 4 Ohms). Every channel is truly independent with its own thermal management, power supply, and fully balanced topology. The A7 is an extremely high-biased design that maintains class A operation for nearly any musical or audio signal. We allow the amp to slide into class AB at levels above 50W into 4 Ohms, typically well below 1% of the time with most content. The thermally controlled fans are true variable speed and usually off, only turning on with very high power demands. This ensures that the A7 is able to perform within the temperature threshold necessary to produce a powerful and high quality audio output. The A7’s extremely low distortion and rich energy is the driving force behind our home cinema and Hi-Fi systems.
