His avr doesn't use the LFE+Main terminology, it does have a Double Bass option, tho IIRC not quite the same on some Onkyos in that setting a crossover isn't always an option (to use as a high pass for the speakers like you can generally do with D&M units in conjunction with the LFE+Main setting).....
Finally got around to checking settings. AVR LFE should be at 120? It is at 120. You said sub xo at 80. Does not LFE defeat the crossover control on the amp plate? Or do I have that wrong? I haven't hooked up a Y. Still just LFE.
The crossover on the plate amp is for when you don't have crossover control on your AVR. When using the AVR crossover setting the plate amp crossover should be set to max so that the AVR can do its thing. I don't see the Y adapter making much difference but no harm in trying. Best to turn up the AVR subwoofer trim, but as mentioned it's preferred not to use positive values.
I think Ryan meant just the crossover (that between speaker and sub) for 80. LFE inputs on subs generally bypass the sub's low pass filter, but not all...safer to just set it at max value in any case.
This is an interesting question which I cannot answer with certainty, but my susposion is that this is why you defeat any setting on the Subwoofer Plate Amp. You are telling the AVR "brain" to set a specific XO, UNLESS it is LFE Channel in a movie or other multi-channel encoded program (ie 5.1, 7.1, etc).
HSU vtf mk2 12"
According to your manual you can set your "crossover switch" to "out" to bypass the sub's low pass filter.
I said the model wrong. It's a VTF-2 MK5. I did have that switch set to out. Better to leave it there?
Something is not right. If your sub output is at 0 db. then that should be plenty of voltage to activate the auto on. Changing the setting on the sub will not help as the sub volume circuit is downstream of the auto on circuit.
After setting the Quick menu sub out setting to +4 db, it is playing fine at a moderate volume. But the sub was already on since I had the TV on previously. It is the only change that I made I think since my OP.
Generally you just want the avr providing bass management, altho I suppose in some rare circumstances you might want both filters active (called cascading filters).
I agree you don't want to be using +ve trim levels and you should not have to.Squish...
Re. Positive Trim Levels and the reason this should be avoided is that Positive Boost is done in the Digital domain. Once the signal is boosted thusly, it is much easier for the signal to clip at the Pre-Amp level. Amplifying an already clipped signal is the absolute fastest way to court damage.
This isn't a guarantee that it will happen, but in the realm of "best practices" should be avoided.
Apparently you do if you have an Onkyo. Don't get me wrong, I am very happy with this amp.
It has Dirac Live, which I did not use. I calibrated with the mic though in my primo seating position. I do not recall what Onkyo calls that or if there is a name for it. Like Yamaha's YPAO.
