Frequently asked questions
Can I use these products together?
Yes—they work in the same wireless ecosystem. The GN50 ESP is the microphone module that connects to a wireless transmitter, and the CU400 charges those transmitters. You need both to have a complete functioning wireless mic system.
Which AKG wireless systems do these products support?
The GN50 ESP integrates into AKG wireless systems that accept modular gooseneck capsules. The CU400 specifically charges HT450/470 or PT450/470 transmitters in the WMS450 and WMS470 series. Verify your transmitter model before purchasing the charger.
What's the advantage of the CU400's drop-in design?
You can place entire transmitters directly into the charger without removing batteries, saving time during fast-paced live events. The unit automatically monitors voltage and temperature to prevent overcharge damage.
Is the GN50 ESP suitable for vocals or instrument miking?
The GN50 ESP is a modular gooseneck component designed for wireless microphone systems; its suitability depends on which capsule you attach (CK31, CK32, CK33, CK47, CK80). Different capsules are optimized for different sources—check capsule specs for your intended use.
