Frequently Asked Questions
The infrared interface establishes a link between the transmitter and receiver, automatically tuning the receiver to a free frequency. While generally reliable, obstructions can disrupt the signal, so maintain line of sight.
The transmitter is compatible with most standard IEMs; the key is ensuring the receiver’s output matches the IEM’s input requirements.
Real-world range with 50mW is typically around 150-200 feet, but it’s highly dependent on environmental factors like interference and obstructions.
