Frequently Asked Questions

While it offers a good signal-to-noise ratio, the limited frequency response and UHF transmission make it more geared towards live performance, not critical broadcast recording.
Given the 470-526 MHz frequency, directional antennas with 3-5 dBi gain would provide a noticeable range improvement, especially in environments with significant RF interference.
The transmitters use standard AA batteries, offering flexibility and cost savings; however, performance will vary based on battery quality and charge level.
