Compact CAT5 Audio/Video Splitter

6.Poor audio quality at the receiving end

Only use powered speakers with the splitter and receivers. It is also good practice to set the audio level (volume) output of the PC about 1/2 to 2/3 from the maximum and use the volume knob of the speakers to adjust the volume to the desired level. A low volume signal output from the PC reduces the signal-to-noise (S/N) ratio, whereas too high output amplitude can cause saturation and clipping to occur.

7.Substituting power supplies

The splitters rely on the AC power adapters that are supplied with them. The adapters generate a floating 12 v DC power for the unit. If you intend to use a different external DC power that is referenced to ground, the splitters will not function properly.
