adding vu meter to your computer

Posted on Feb 5, 2014

From a SONY double tape decks with model number `SONY TC-W230` I have picked a nice LCD VU-meter. I have decided to add it to my computer tower case. the following steps explain how to do this. this is based on IC lablelled CXD1017 (impossible to find a datasheet) on the printed circuit it is easy to identify the connected wires (second photo redrectangle) so we can see: The first think that I have done is to look for the

schematic circuit of this HIFI equipment and after a long time I have filnally found the service manual. So the following photo shows the VU-Meter schematic diagram: The lapms used in the VU-Meter to lighten the LCD consume a lot of current this why they are powered by a symetric source -6V and 6V. I have decided to replace them with 4 white LEDS. Before I have decided to mount the VU-Meter I have decided to test it because I have picked it from salvaged audio equipement and I don`t know if it function or not. As my computer is connected the AUX input of my HI-FI system via RCA connectors I have to add an adaptor to convert the audio channel from jack connector of the computer sound card to RCA connectors going to the HI-FI system. this circuit is a simple parallel connexion between jack connector and RCA connectors.
