For permanent screw-on installation, AKG offers goosenecks in various lengths: GN 15: approx. 15 cm (6 in.); GN 30: approx. 30 cm (12 in.); GN 50: approx. 50 cm (20 in.). Except for the GN 30 OC with unterminated cable ends, all come with a DPA in-line XLR phantom power adapter with integrated 200 Hz bass rolloff and LED ON/OFF jumper.

The DPA connects to any standard mixer input with 9 to 52 V power supply.
The mini XLR connector will thread through any hole from 11 mm (0.44 in.) in diameter.
This eliminates the need for large holes or awkward unsoldering and resoldering of the much larger phantom power adapter during installation.

See mounting examples

Standard accessory: Phantom power adapter

The external phantom power adapter of the GN series makes setting up the goosenecks much easier, since a small hole will suffice for threading through a mini XLR connector.
Having disconnected the cable, the integrated bass cut can be set quite easily inside the phantom power adapter.
The phantom power adapter will operate off any available phantom power supply from 9 to 52 V, powering both the condenser capsule and the LED ring.

Available capsule modules for GN 15/GN 30/GN 50: CK 31, CK 32, CK 33, CK 47, CK 80.
