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).
