The XLII adds a gentle presence boost and brighter top-end—reminiscent of the classic C12 - while the XLS keeps a flatter, more neutral frequency response for transparent capture.​

The bass‑cut switch offers 40 Hz, 80 Hz, and 160 Hz roll‑offs to tame rumble or proximity effect.

In Lock Mode, all controls on the microphone are disabled so the settings you selected for a specific application (polar pattern, pre-attenuation pad, bass cut filter) cannot be changed unintentionally.

• Enter Lock Mode - Press and hold one of the arrows on the polar pattern selector for at least 2 seconds. All controls are disabled and remain disabled even if phantom power has been interrupted (e.g., if you disconnected the microphone and connected it again later).

To indicate that the microphone is in Lock Mode, the LED(s) above the currently selected polar pattern will be lit red momentarily when you press any key.

• Exit Lock Mode - To unlock the selectors, press and hold the polar pattern selector for at least 2 seconds.

AKG selects twin microphones by computer to ensure virtually identical response across the full frequency range.

With pads engaged, Maximum Sound Pressure Handling withstands up to 158 dB SPL before 0.5 % THD.​

If the output nears clipping, the active pattern LED turns red for about three seconds.

It operates exclusively on standard 48‑volt phantom power to IEC 61938.

The microphone offers nine selectable polar patterns indicated by green LEDs.​​

You can lower the output by ‑6 dB, ‑12 dB, or ‑18 dB using the rear selector.

​Equivalent noise is as low as 6 dB‑A, giving an 88 dB signal‑to‑noise ratio.​

​Each package includes the H85 shock mount, PF80 pop screen, W414 X windscreen, a frequency response trace, and a hard case.​

Exterior dimensions with Handle: 11.25" x 8.75" x 5.2".

The weight of the case with microphones and all accessories is 4.5 lbs.
