The 414EB is the second-generation C414 microphone from AKG. Like its predecessor, it combines AKG’s famous CK-12 capsule with a solid-state amplifier circuit.
The EB revision features a 3-way high-pass filter, and upgrades the -10dB pad to include a -20dB option; both are selectable via switches on the rear of the mic body, below the microphone capsule.
The left-side switch controls the pad: 0dB, -10dB, -20dB.
The right switch controls the HPF: flat, -12dB/octave @ 75Hz, -12dB/octave @ 150Hz.
As with the original C414, the EB provides 4 polar patterns — Cardioid, Omni, Figure-of-8, and Hypercardioid — selectable via a switch below the capsule on the front of the microphone body.
