2.4 GHz audio transmitter module
Multi-channel stereo audio transmitter working in the 2.4 GHz band
SKU 8110-TX-AUDIO-24EAN 8219671028257Item type: AssembledRF transmitters
Description
Multichannel stereo audio transmitter operating in the 2.4 GHz band. It features eight channels and digitizes the input audio signal using a 16-bit A/D converter. Sampling occurs at 44.1 kHz, achieving so-called “CD quality” with an audio signal bandwidth between 20 Hz and 20 kHz. The radio carrier has a power of +10 dBm (10 mW) and uses FSK modulation, which offers high immunity to interference. It is the ideal complement to the RX-AUDIO-24 receiver, as its eight channels use the same operating frequencies and a D/A conversion system complementary to that used by the RX module.
