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 optimising the system noise performance at each volume setting.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe LA4 provides input selection and volume control without adding an “electronic fingerprint” to the music. Discover the difference!
