The easiest way to examine the range is to look from the top down. The C414 XLII and XLS variants are the flagship mics in the range and feature the distinctive 414 shape, grille, and switch positions. The latest version of the mic was split into two models, the XLS and XLII which are easily identified by the colour of their grille as the latter XLII features a Gold grille.
Feature-wise, the mics are identical, sonically however the XLII features a very slight presence ‘boost’ in the capsule design above 3kHz that gives it a more airy and open top end - useful when miking vocals to capture a contemporary 'crisp' sound, or when miking instruments at a distance. Other than this slight EQ difference, the two mics are identical in features.
The ‘Polar Pattern Available’ column on the above table is the biggest giveaway as to what makes these mics special. That’s not a typo, they genuinely have 9 Polar patterns. Assigned using the front panel switch, each of the 5 major positions has a middle and intermediary step for modified versions of the popular polar patterns including Supercardiod that sits between Cardioid and Hypercardioid as well as Wide Cardioid that sits between Supercardioid and Omni patterns.
By having options for each of these polar patterns, the engineer can pick one that works well for them and provides the perfect balance between maximizing the source and minimizing bleed.
