A recent editor changed "An L pad is a special configuration of rheostats" to "...special configuration of potentiometer" (emphasis added). I've reverted this because I disagree with this change on several counts:

There are also switched networks using fixed Rs and typically a rotary switch.

"This constant-impedance load was important in the days of vacuum tube power amplifiers because such amplifiers often did not work efficiently when terminated into an impedance greatly different than their specified output impedance. Maintaining constant impedance is less important to modern amplifiers using solid state electronics, so L pads are rarely seen today."
Is this really valid? Tabby ( talk) 05:28, 3 January 2008 (UTC)
It is unclear what the origins of the 'L' are. The first sentence implies that it comes from 'Loss' Pad or 'Losser' Pad, however it later states that the name comes from the arrangement of the resistors...? —Preceding unsigned comment added by 77.100.216.53 ( talk) 20:37, 5 April 2009 (UTC)
The introduction starts off defining the L-pad as device specifically for controling the volume of a speaker. But then there are later sections that deal with applications that are not related to speakers. I would like to make the introduction general enough to cover all the included information and move the speaker related information to its own section. Nothing would be lost or changed.
