Nevíte někdo, co autor na této stránce skoro dole v kapitole "How Does It Sound?" myslí tím umístěním a pájením zpětnovazebního odporu R5? Původně jsem si myslel, že jde o možnost snadné jeho výměny z důvodu požadované změny zisku (citlivosti, gainu), ale asi to má jiný důvod. Přece zpětnovazební odpory se normálně neumísťují nutně co nejblíž pouzdru... Možná kvůli layoutu, zjednodušení návrhu DPS... Fakt tomu nerozumím, co ten odstavec znamená...
"The sound quality is very good - as I said at the beginning, I would not call it audiophile hi-fi (but then again - I might, with caveats), and provided the amp is never allowed to clip it sounds excellent. Because of the overload protection (which I have never liked much in any form), this amp provides somewhat nastier artefacts as it clips than most discrete amplifiers.
For those who think an incredibly short feedback path length is actually important (hint: it's not), a surface mount resistor can be used for R5, either soldered directly to the leads (pins 2 and 4) or the pads on the copper side of the board. This will provide a feedback path of less than 20mm in total, and could be made less than 10mm (at the risk of damaging the IC with excess heat). IMO attempting this is just silly, and you'll never hear the difference in a blind test. It's extremely doubtful that you'll be able to even measure any difference, and the IC isn't designed for microwave operation (where a short feedback path is actually important).
This amp is ideal for Hi-Fi PC speakers, and could also be used as a midrange and/or tweeter amp in a tri-amped system - there are a lot of possibilities, so I will leave it to you to come up with more."
