Benchmark LA4 Preamplifier
The Benchmark LA4 line-level preamplifier features the best analog volume control system available at any price.
At each volume setting, relays select pairs of high-precision resistors to attenuate the music to the desired level. This system eliminates the noise, distortion, and L/R balance issues found in more conventional analog volume control systems. Traditional potentiometers and integrated electronic volume controls are the weakest link in most Hi-Fi signal chains. The LA4 removes the weak link while optimizing the system noise performance at each volume setting.
The award-winning LA4 is designed to keep noise and distortion below the 0-dB SPL threshold of hearing at each of the 256 volume control settings. No preamplifier delivers a higher degree of transparency.
The LA4 provides input selection and volume control without adding an "electronic fingerprint" to the music. Discover the difference! Listen to the music, not the electronics.
