I've googled this extensively and searched the forums here, but haven't really found an answer so I'm hoping someone can help. I have a new Def Tech Supercube 2000 sub. There is no on/off switch, just a light that turns red. I turned the sub to halfway as suggested and ran the YPAO for my new Yamaha 1050.
The sub doesn't seem to turn on unless volume gets quite loud. Is this something that would be impacted by the receiver settings? The current setting is -10db so would that be causing my issue?
I notice that if I play a blu ray or play SONOS or the tuner, the red power light will not be on, and there will be no bass. If I unplug the wire in the back of the sub and plug it back in, the red light goes on and I get bass. If I turn the volume up, sometimes that will get the red light on. Sometimes that light will stay on, but other times, within 15 or 30 minutes, the light will be off again. Sorry if these are dumb questions but...
1. Does it make sense what the sub is doing?
2. Should the red power light turn on and off based on volume of the movie/song? Should it turn off in the middle of a movie, regardless of volume? I guess I assumed the sub power light would always be on if the receiver is, but is this not the case?
3. How can I be sure to get the sub to turn on and give me bass all the time, using the settings on the receiver? Does it just involve manually changing that -10db to closer to -5db or 0db?
I plan to call Yamaha as well as Def Tech for help, but I wanted to get some background info from the gurus here, so I have an idea of what I'm talking about.
Thanks in advance!
