Bests & Worsts Reviews from Amazon

As an Electrical Engineer and an avid audiophile, I have been building my own version of this product for many years. It is simply a dual pot (slang term for a potentiometer)set up as a stereo audio attenuator. I was pleased when I found this one available. The unit is nicely built, and the price is reasonable. But no specifications were offered, so here is what I measured: The pot measured 52.7 K OHMS (left channel) and 52.1 K OHMS (right channel) LINEAR TAPER. I did not do any tests on how well the two sections "track" except at the mid-dial position, tracking was acceptable. This is within normal specifications for a (nominal) 50K Ohm dual potentiometer, Linear. Unfortunately, the pot is a LINEAR TAPER and not an AUDIO TAPER as it should be for a product sold as an audio product. AUDIO TAPER (also called LOGARITHMIC TAPER) is used for potentiometers that control audio volume because human ears respond to sound logarithmically, and thus, incremental adjustments of the knob will produce equal increments of volume (loudness) as perceived by humans. If a LINEAR TAPER pot is used as a volume control, the lowest settings of the knob will make proportionally greater changes in perceived volume, and the higher settings will produce a much smaller effect in volume. Thus, it may seem that the adjustments at the low end are very "sensitive" or "touchy" whereas the adjustments at the high end are relatively ineffectual. Both types will basically do the same job, but the AUDIO TAPER pots will do it better. If you want to learn more about the TAPER of potentiometers may I suggest reading the Wikipedia entry under "potentiometer" where it is all explained in greater detail. Bottom line; this product will work in most applications, depending on relative signal levels. Likely only the techies will find value in these comments
