The RC-5 Remote Control Protocol The DIYHFS‟s UVC uses industrial standard Philips RC-5 code The RC-5 protocol was developed by Philips in the late 1980s as a semi-proprietary consumer IR (infrared) remote control communication protocol for consumer electronics. However, it was also adopted by most European manufacturers, as well as many US manufacturersRead More

4 – Using Universal Remote Controls to operate the Ultimate Volume Control
Control The UVC can be remote controlled from any remote control that implements the RC-5 remote control protocol (see Appendix 1) and supports audio components (Amplifier/Preamplifier). Examples of relatively inexpensive remote controls that are known to work are the Altronics stock number A1009 “Universal 6 in 1 Remote Control” and the Altronics stock number A0977 “6 InRead More
Appendix 3
The UVC based 2 Channel buffered passive Linestage The picture below illustrates the complete installation of all components of the UVC system in a compact chassis, thus creating a complete passive buffered preamplifier with remote control (requires optional universal remote control). This project is in many ways comparable to “Aunt Corey’s Homemade Buffered Passive Preamplifier”Read More

2 – Audio Matrix Input connections
Simply connect the Inputs using suitable wire or cable (shielded cable is recommended) from your input connectors to the UVC Module. Connections are labeled on the PCB. Make sure the sockets used do not allow electrical contact between RCA Socket ground and the chassis. Connect each RCA input pairs ground connection to the middleRead More
