Wireless microphones aren’t truly wireless until they’re paired with a transmitter, and getting that connection right is key to sound quality and system performance. This article examines how different microphone types interface with transmitters and the challenges involved in matching dynamic range between the microphone and the transmission system.
It explains how analog systems often require variable gain control to align the signal, while digital systems may use stacked converters to accommodate the full dynamic range of the microphone without level shifting. Powering condenser microphones through battery-operated transmitters is also addressed, including the need for DC-to-DC converters when 48V phantom power is required.
Transmitter form factors vary depending on the microphone type, ranging from handheld vocal mics to belt packs and compact units with XLR connectors. Additional features such as low-cut filters, limiters, and audio polarity settings can further support reliable performance in demanding conditions.
