| Was hungry for money installing CCTV cameras back in the day via 4CH PCI NTSC Capture Cards. Restaurant customer was really impressed with the tech and kept making new demands: Q: Can we listen to this cool pandora.com thing over the restaurant speakers? A: Yes, I we'll use the CCTV cables to run audio from your DVR PC (Pentium 4 I think) to the restaurant AMP. I had the bits and bobs in my car to go from BNC to RCA / 3.5mm. Q: That's awesome, now can I talk to the customers to make announcements? A: Sure, see this little speaker icon in the system tray? talk into this mic when you uncheck "mute". Don't forget to mute pandora first. Q: That's awesome, but I want to make the annoucement from the host station. A: Let me grab my laptop... Google: VB6 LPT Port. Google: VB6 Volume Mixer. Copy Copy Paste Paste. Alright, I'm going to mount this old mouse on your wall and solder 2 wires to the clicker (Then to LPT on the DVR PC), it will automatically enable this wall mic when you click the button... |
