There have been multiple AKG 414's over the years that have slightly different specs and slight tweeks to the sound.  The current offerings are the 414 XLS (black grille) and 414 XLII (gold grille).  They both sound like 414's of the past, but they are tuned to be slightly different with different purposes in mind.   If you are looking for the more neutral, detailed and flat sound for recording everything from strings, pianos, vocals and choirs, the XLS is probably more your speed.  Engineered to have a very neutral and detailed response, the XLS will accurately reproduce your source without compromise. AKG calls the XLII (gold grille) more of a C12, and while it is brighter and more exciting than a the XLS (black grille) version, we wouldn't quite go so far as to call it a C12.  The XLII does have a more exciting top end, slightly pushed and more open which can really shine for lead vocals, lead instruments or anything that you want to "POP" in the mix.  The low end on the XLII is also slightly pushed as well which can lower "nasal" vocals.  This is the mic if you are having trouble getting intsturments to sit "up" in a mix. Both mics have been built to very similar specs and features with the 9 polar patterns, High Pass filters and switchable pads.  This makes both ideal for quiet vocals to loud drum kits.  The 414 is an easy choice for your studio, but talk to us so we can help you pick the right version!
