4.If you plan to use the audio functions, install your audio cables into the audio line-in and line-out connectors on the TXB-N.

NOTES:

•To take full advantage of the distance and noise immunity benefits of audio, you must use a 600-ohm impedance matching transformer and twisted pair cable (refer to Figure 10).

•A stable power supply is required for optimal audio performance.
