The AKG C414 B ULS is about as versatile as a condenser microphone can be, which is what's made them a studio staple consistently over three decades. With four selectable polar patterns (cardioid, supercardioid, bidirectional, omnidirectional) on the front and three-position switches on the rear for attenuation and bass rolloff, the C414 B ULS is also the last of the 414s to make use of an output transformer. When compared to the more modern iterations of this mic (TLII, XLS, XLII, C214 and C314), the ULS has a bit more vibe and character to the sound while retaining that "natural" quality that's made every version of the 414 what it is today.
