Frequently Asked Questions

The infrared interface quickly and accurately synchronizes the transmitter and receiver, preventing frequency drift. It’s a reliable method, though direct line-of-sight between the two is needed for initial pairing.
The 120dB dynamic range handles loud vocals and stage volume effectively, but proximity effects and feedback potential still require careful gain staging and microphone technique.
The SB 900A is rechargeable and offers extended battery life, but swapping it mid-performance would require a quick stage break and a readily available spare – plan accordingly.
