Know before you buy
Yes, the 9011 is designed for versatility. You can operate it as a single stereo unit or bridge two units together to function as high-powered mono blocks for more demanding speaker setups.
The switchable transformers allow you to fine-tune the amplifier's sound profile to better match your specific speakers and room acoustics, providing a level of customization rarely found in high-end amplification.
With a maximum output current of 50 amperes and significant pulse power capabilities, this amplifier is engineered to maintain control over even the most demanding, low-impedance speakers without losing musicality.
Yes, the unit features six connecting terminals, allowing you to easily bi-wire your speakers for improved signal integrity and potential gains in clarity.
Given that each unit weighs 95 kilograms (215 lbs), you will need a very sturdy, dedicated equipment rack or a reinforced floor surface capable of supporting significant weight.
The Isolated Gain Cell is a proprietary design that actively compensates for distortion, ensuring that the signal remains clean and precise from the input stage to the output.
