SMc Audio manual VRE-1 Preamp, Troubleshooting

Page 10

This is important because I cannot fully break-in your VRE-1 before shipping. Your preamp has been thoroughly tested and listened-to, but this is just the beginning. I make every effort to present you with a good initial impression, but beyond that it is up to you to complete the break-in process, and to *understand* that it will take time.

Break-in is a process of using your equipment - not simply leaving it turned on. You must have something playing (music or some sort of break-in signal) to get the job done. I feel that playing music normally works perfectly well, but there are special CDs and LPs made as “break-in discs” that are favored by some. Check with your audio dealer or music supplier if you are interested in these.

The main thing is to understand that it will take some time for your VRE-1 to realize its full potential, and I urge you to relax and enjoy listening to music while it breaks-in, warms-up, settles-down, or whatever you want to call it.

Troubleshooting

Problem: No sound, no lights, no nothing.

Solution: Check your AC power connection to the wall outlet to make sure you are getting power; check the AC Mains fuse to see if it is blown - replace if necessary.

Problem: You have lights and hear the relays click, but no sound.

Solution: Your analog power link cable may not be connected properly - check for proper cable connection. Check the obvious - is your amp turned on? Correct input selected? Source playing? Check the interconnect cables to and from your VRE-1. Be sure you have selected a working input.
