Catchbox Plus system uses the license-free DECT 6.0 (1.8 / 1.9 GHz band) transmission standard that has a clean and uninterrupted signal.
DECT, being a radio frequency, comes with certain limitations on how far the radio wave can travel. This affects the distance that wireless microphones can be from the receiver.
DECT is known for its power and reliability within the professional audio community. In ideal conditions with a clear line of sight (no obstacles between the receiver and microphone), the DECT system can achieve a range of up to 100 meters (330 feet). However, this range is reduced in environments with obstacles such as concrete, or brick walls, or when the equipment is placed inside a rack. These obstacles can interfere with the signal, making it challenging to guarantee the same range in every setup.
In the US, the system supports up to 6 microphones in one space, whereas in the EU, it supports up to 10. It's important to note that this limitation applies to any DECT frequency device, not just Catchbox microphones.
