Professional Microphones & Wireless Systems


Wireless microphones systems are becoming increasingly popular in live settings because they allow the user to move freely around the stage. These systems must be able to capture the wide dynamic range of a singer’s voice and compress this signal enough to meet strict bandwidth limitations. In order to avoid interference with other RF operating devices in the VHF, UHF, and 2.4 GHz bands professional microphones are developing frequency agile systems that can scan the available band and select a frequency of operation that is open. TI enables wireless microphone manufacturers to innovate by providing:

  • Low noise, low total harmonic distortion (THD) audio amplifiers for preserving excellent audio quality in the microphone preamplifier and receiver output subsystems
  • Audio data converters and low power digital signal processors (DSPs) capable of sampling and processing HD audio rates up to 192 kHz and compact size suited for small foot prints
  • RF synthesizers which support direct digital FSK modulation and are very low power for extending the transmitter battery life

Wireless microcontrollers (MCUs) and SoCs for highly integrated solutions with a built-in wireless audio transmission protocol and coexistence mechanisms to avoid interfering with, or being interfered by other 2.4 GHz radio systems
