The SA1X Level Control
The SA1X level control was designed for Pro Audio balanced input applications. They are commonly used as precision level controls between mixing consoles and amplified speakers in recording studio monitoring rooms. 
No distortion is added to your signal path while performing level control. 
(Active preamps add in at least some distortion.)
Goldpoint precision, 4-section (balanced stereo) stepped attenuator for low noise and excellent channel-to-channel signal level matching.
Ultimate sonic clarity and precision at a reasonable price.
