3. Setup Guide

3.1. Connecting the Transmitter to Your TV

The Holdsound BKM100 transmitter offers multiple connection options to your television or audio source. Choose the method that best suits your device.

USB Audio Connection:
Plug the transmitter directly into an available USB port on your TV. Ensure your TV's audio output settings are configured to output audio via USB if necessary. This method often provides both power and audio.
Optical Audio Connection (TOSLINK):
Connect one end of the provided optical cable to the "Optical Out" port on your TV and the other end to the optical input on the transmitter. You may need to adjust your TV's audio output settings to "PCM" or "Stereo" if "Dolby Digital" is selected, as the transmitter may not support Dolby Digital.
3.5mm AUX Audio Connection:
Connect one end of the provided 3.5mm AUX cable to the headphone jack or "Audio Out" port on your TV and the other end to the AUX input on the transmitter.

Important Note: The Holdsound BKM100 system is designed for direct connection to TVs or audio sources with physical audio output ports. It is not compatible with streaming-only devices that lack these physical outputs.
