The SA1 Level Control The SA1 Precision Level Control can take the place of complex active preamplifiers in many systems,  and can serve as complete preamp solutions for audiophile purists.  A typical application is as a level control between your CD (or DVD) player and your power amplifier(s).  They are also great for general use on any audio test bench.  No distortion is added to your signal path while performing level control.  (Active preamps add in at least some distortion.) Goldpoint precision stepped attenuator for low noise and excellent channel-to-channel signal level matching. They cost only a fraction of what high quality active preamps typically cost.

However, unless otherwise requested we ship them with the 25K stepped attenuator value.
