Can I use AA batteries with GLX-D?


I perform all over Europe. What system should I buy?

The 2.4 GHz range that is used with GLX-D systems is usable globally without any need for registration. There is no UHF TV band used for BLX that can be used all over Europe and in many countries you need to register the systems.
