I am by all means a novice when it comes to home theater. I moved from one apartment to another and finally decided to upgrade to a digital receiver and replace my speakers. My current system includes a Pioneer VSX-D850S receiver with Cerwin-Vega AVS-632 home theater speakers. DVD, Hi-Fi VCR, and 25” TV complete the system. I was also considering a set of JBL speakers (NSP1II), but since the set didn’t include a subwoofer and I didn’t want to spend another $300, I had to pass. So here’s the deal. This is my 1st time owning a subwoofer. My previous speakers were towers and provided the necessary bass. While watching TV (through the VCR), the sub tends to turn on and off at different times. I’ll be watching one channel and it will shut off, change the channel and it will turn back on. I can watch a DVD and it never turns off. This leads me to believe that there may be an issue with how audio is being received from my VCR. The crossover frequency is set to IN on the sub to allow the receiver to control the frequency. The frequency is set at 200Hz on the receiver since all the speakers are classified as small. I read through the forums FAQ, and hooked up a Y-adapter to plug-in to the sub’s L and R input. I’ll have to see if this helps or not. I also plan on purchasing a SPL meter and properly setting up my system. I could not believe the amount of information that was in this forum. So anyway, I was wondering if anyone has seen this before. Is this normal or do I need to purchase a new VCR? Any input would be welcome.
