How To Get More Usable Steps For Your Stepped Attenuator -Pre-Attenuation: It gets loud too soon (too much gain). With Goldpoint stepped attenuators, normal listening levels are typically when the knob position is between 9 o'clock and 2 o'clock. But if you have high output level signal source equipment (such as CD players), high gain power amplifiers, and/or very efficient speakers, a "regular" stepped attenuator may not provide enough attenuation for you, and you may experience the following: 1) The sound level is too high when turning the knob up only a few clicks - (8 o'clock, for example). 2) Turning the knob up past 12 o'clock makes the sound level higher than you would ever want it to be. If either of the above conditions exist, a good solution is to install a pre-attenuation circuit. This adds attenuation to the amount provided by the stepped attenuator.  The pre-attenuation circuit (resistors Rp1 and Rp2) attenuates the Input signal before it reaches the input of the stepped attenuator. If the two resistor values are chosen correctly, the Input Impedance of the attenuator plus Rp1 and Rp2 will be the same as the Input Impedance of the stepped attenuator by itself. This is desirable so that the signal source output has the same load as before. The following table shows the amount of additional attenuation provided by different  Rp1 and Rp2 resistor value combinations - for use with different value stepped attenuators.

-It does not get loud enough soon enough (too much attenuation). With Goldpoint stepped attenuators, normal listening levels are typically between knob positions 9 and 2 o'clock.      But if you have to turn the knob way up before you can really hear anything, as could happen when using a stepped attenuator in a Passive Preamp, our "regular" stepped attenuator may be providing too much attenuation for your system. If you want to reduce the number of silent, unusable knob positions, here's what you need to do: Install a resistor between your Ground point and the Ground pad on the stepped attenuator, as illustrated above. This  resistor causes the first knob position (which would normally be the "Fully OFF" position) to be some level above "Fully OFF".  Although this is not the optimum way to get the volume control to give a usable listening level sooner in its rotation, it is an easy way to do it. There would no longer be a full OFF knob position, but in some cases this still works out just fine. The following table shows Rg1 resistor values to move the first knob position level some decibels above full OFF:
