    My BFD showed up today and during setup, I can't get the sub to play. I'm using a Rotel RSP-1066 processor and have a RCA going from the LFE preout to a RCA-to-1/4 jack into "inputs 1." Then out of "outputs 1" another 1/4-to-RCA with a cable running to my sub. I've read through the first sections of the snapbug guide, set the "operating level" button to -10dBV and pressed the "in/out" button until it blinks. At this time I should be able to play any source and monitor input via the LEDs, correct? Nothing happens, even when I turn the Rotel sub level up to Max. I've tried both inputs with nothing. Help! This has to be simple, am I doing something wrong or did I get a bum unit? Thanks.

    I just got mine a few weeks ago and it sounds like your connections are correct. Have you tried plugging the cable from your LFE to the sub pre-out with everything else exactly the same (i.e. exactly the same dolby settings on your processor, the same cd/DVD playing)? Could it be that somehow your dolby setting are not sending LFE out? The other thing you can do, if you have an ohm meter is check your cables. Check for continuity between the tip of the RCA to the tip of the 1/4 phone plug. The last thing to check (although I'm not sure how this could cause a problem) is to check the settings on the filters you are using. Make sure the all twelve filters are set to OFF (the display actually displays "OF" and make sure the filter bank (1 of the ten) is set to "PA". This should not prevent you from monitoring the inputs but I have had the case where one of the other settings seemed to cause my outputs to gradually go down to nothing (I assume it's one of the auto feedback destroyer modes). I think if it was just that your LFE out was to low a voltage that you would hear something, though it may not be loud enough.

    Good luck.

    I just thought of one more thing to try. Hook the analog out from one channel of a CD player directly into the BFD. I did this when doing initial testing with a bass test CD and it worked fine. This would eliminate the whole processor/dolby thing as a variable.

    Thank you, thank you, thank you! Paul hit the nail on the head, I got stereo 1/4" adaptors. Just got back from Radio Shack with monos and all is running. Whew, I knew it had to be something simple and stupid like this. Thanks for the help guys, now off to do some tuning [​IMG]
