Please donate to Pinside, support the site and get a next to your username to show for it! L l pad hook up can also be used at line level, mostly in pro applications. L pads may not necessarily use continuously variable rheostats, but instead a multi-position rotating selector switch wired to resistors on the back. But perhaps its the numbes at the end of ths link. Would that reduce o likelihood of 'blowing' the l-pad?impedance of your cone speaker rises at high frequencies so when the 8 ohm tweeter load comes in the amp will see a proper loading. On my L-pad, which is an 8ohm model, I connect an 8ohm speaker and the DC resistance seen by the amp stays within about ohms if I remember correctly as I adjust the L-pad.

Topic ID: Messages 4, Dimming Backbox L pad hook up. The second rheostat usually has a special taper function of resistance versus rotation to accommodate the need for constant input impedance. Share this! Does it matter? A constant-impedance load is important in the case of vacuum tube power amplifiersbecause such amplifiers do not work as efficiently when terminated into an impedance greatly different than their specified output impedance.
