In Reply to: Back to an attenuator ... posted by SGA500 on January 22, 2006 at 02:46:13:
The most thorough description of attenuation (L-pad, T-pad) that I know about was written a few years ago by VoltSecond. His pages were written with the Bottlehead Foreplay in mind, but the same general principles apply. Take a look at Figure 1 and *STUDY* section 7 and Figure 7.1. Although an L-pad is simpler, with a T-pad, you can control the input and output impedances as well as the attenuation you want, all for three resistors per channel. Use good quality metal film resistors and you should be very happy with the result.Good luck,
Peter
