The SA1X Balanced Stereo Precision Level Control
The SA1X Balanced Stereo Precision Level Control was designed for Pro Audio applications. They are commonly used between mixing consoles and amplified speakers in recording studio monitoring rooms. Our customers typically rave about how clear they sound and how handy they are to use. 
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.

About Stepped Attenuator Values:
We usually put 25K stepped attenuators into our SA1, SA2, and SA4 Passive Preamps. The 25K value allows the greatest flexibility, so these units can be used with nearly all solid-state and vacuum tube gear. We usually put 10K stepped attenuators into our SA1X and SA2X Precision Level Controls as these controls are most commonly used with amplified speakers (which have internal solid-state amplifiers). However, if requested, we will ship your SA Passive Preamp / Precision Level Control with any value stepped attenuator you choose from our stocked values (5K, 10K, 20K, 25K, 50K, 100K, or 250K).
