Brand
Balanced Audio Technology
Balanced Audio Technology (BAT) is a renowned American manufacturer specializing in high-end audio equipment, including fully balanced tube and solid-state power amplifiers, preamplifiers, and phono preamps. With over 25 years of expertise, BAT has earned a reputation for meticulous engineering and handcrafted products, distributed in more than 40 countries.
At the heart of BAT's design philosophy are several key principles:
Fully Balanced Design: By employing both positive and negative phases of the audio signal throughout the signal path, BAT’s balanced circuitry minimizes common-mode noise and interference. This design ensures superior signal integrity, reduced noise, and enhanced channel separation for a cleaner and more accurate audio experience.
Dual-Mono Construction: Each channel, left and right, is powered by an independent power supply, eliminating crosstalk and interference between channels. This construction enhances clarity, imaging, and soundstage for a more refined listening experience.
Zero Global Feedback: By avoiding global feedback loops, BAT's designs preserve the natural characteristics of the audio signal. This approach ensures greater transparency, tonal balance, and a more authentic and engaging sound.
Balanced Audio Technology’s dedication to these principles guarantees that their products deliver an unparalleled listening experience, maintaining the purity and natural beauty of the original audio signal.
