Switched the line level input to the subwoofer's right RCA jack and bingo - subwoofer works. Connected left line level RCA input to the Yamaha subwoofer #1 output and the Yamaha surround back left speaker ground (not used - 5.1 system for now) to the subwoofer's left speaker level input - did not work. Excellect troubleshooting logic that I would have never thought to try. You are the Man (or Guru or whatever you prefer). If speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp. Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds). Connecting speaker inputs possibly restores the ground. I'm thinking you have an open shield ground on the RCA input side. Usenet newsgroups.(See below for what's new.) Send corrections, additions, and new questions to. I will probaby open up the VR-2000 tomorrow since I'm now feeling cocky.Īirbnb can be an awesome service for frugal travelers, and it feels especially great to use when the only other option is staying at an overpriced boutique hotel in. Probably from overly-agressive or repeated RCA cable connections. Spinrite V6 0 Rapidshare cracked#Well, I opened up the VR-500 and poked around for an hour before I found the problem - cracked solder connection between the grounds on the line level inputs and the rest of the ground circuit on the board. I will probaby open up the VR-2000 tomorrow since I'm now feeling cocky. The speaker level inputs/outputs appear to be working properly although I have only tested with a single (left) surrpund back channel. The buzz/hum get louder/softer with an adjustments to the subs volume control, changes tone/frequency with adjustments to the crossover control and disappears entirely when a speaker level input is connected (I assume that this is because a speaker level connection disables the line level inputs jack). In fact, as soon as any cable is plugged into the line level inputs (either the right or the left) the hum/buzz starts - even with the other end of the cable connected to nothing. I have tried connecting it to the subwoofer out jacks on three different receivers, and a DVD player (with 7.1 analog outputs) with the same result - loud buzz/hum with no other LFE or bass reproduction despite crossover or volume settings. As soon as anything is plugged into the line level RCA jacks, the subwoofer produces a loud buzz/hum. I have a Boston Acoustics VR-500 Subwoofer with a problem.
