XSP-1 bass management with HT question

[Deleted]

Although I know how HT By Pass works in a preamp, how does the XSP-1 work with subs so that your subs can be used both in a 2.2, and HT system? Do you use one on the inputs on the XSP-1 from your HT processor, and and then sub outs>subs?

[Gary Cook]

Whilst it has 2 sub outputs, the XSP-1 only has one input. So you feed it with the combined input from the processor. For HT that means dual mono subs.

Yep, I set the One sub out ( from my AVR ) to the XSP-1 and set it as fronts when using 4 subs for HT and then the other two subs ( splitter) are set to rear for HT out of my AVR . Works and sounds great!

Hey Gary.....so would you use a Y cable out of the HT unit to any of the L/R "ins" on the XSP-1? And then HT "By Pass" mode will allow routing of the LFE from the HT unit through the XSP-1 to the subs?

Thanks,

Devlon

You could use a Y cable if the processor only has stereo LFE output. But I can't say as I have ever seen a processor that doesn't have a mono LFE output and/or the ability to switch to mono such that both LFE outputs are the same content.

Ok, I am still not clear here. Let me try to explain this again a different way.

*The HT processor has 1 RCA sub out
*The XSP-1 has RCA inputs that are left and right in.
*The XSP-1 has sub outs that are left, right, and sum

By mentioning the sub Y cable I am conceiving that:
* The single end of the Y is plugged into the single sub out on the HT processor
* The L/R of the Y is plugged left, and right into one of inputs on back of the XSP-1
* From the sub outs on the XSP-1 I now have the choice, of connecting one sub to the "Left Output" and the other sub to the "Right Output"

And, when HT By Pass is selected I can use these two subs with my HT processor.

Is my thinking correct on this?

One RCA sub pre out from your AVR to sub in of the XSP-1, two subs out will be mono. They are all active with the same signal for HT.
no Y splitter is required unless you want another sub coming directly from your AVR.

Nick has it right here!

1 rca out of avr to xsp1 in ... using l and r outs will give you mono subs for movies BUT


If you hook up a cd player to the xsp 1 (no avr) the subs outs then will be STEREO L AND R..


your making it to complicated I think!

Dang it man. I just now spotted the sub in on the rear pic on the product after you said this. Geeze. Would have saved a lot of typing.
Ok, another question generated from all this......so with only one sub "in" what are the different scenarios that L/R sub out vs Sum sub out would be be used?

Thanks again people

Lol! There is a Dspeaker Dual Core 2.0 that I want to blend into the mix for sub eq for 2.2 only. Didn't want to go there.....too complicated. But knowing exactly how the XSP-1 sub input/outputs work gives me a clearer view of how the DS DC 2.0 can be incorporated.

Thanks!

Please Show & Tell if/when you accomplish this. Very interesting.

I'm not sure why you would want to (run separate subwoofer equaliser) for HT when you have a Sherwood R-972 to do it already via Trinnov. If you want it for 2.2 music then simply connect it between the XSP-1 and the power amp/s using RCA's or XLR's. Like this using the bass management in the XSP-1;

Source Left ----(RCA or XLR)----> Left Input XSP-1 Left SW output -----(RCA or XLR)----> Dspeaker Dual Core Left ----(RCA or XLR)----> Subwoofer Left
Source Right ---(RCA or XLR)----> Right Input XSP-1 Right SW output ---(RCA or XLR)----> Dspeaker Dual Core Right ---(RCA or XLR)----> Subwoofer Right


I'm not sure why you would want it (separate subwoofer equalisation) for HT but if you do then between the XSP-1 and the power amp/s (as above) will also work. You could connect it like this;

                                                                                                       XSP-1 Left SW output ---(RCA or XLR)----> Dspeaker Dual Core Left ---(RCA or XLR)----> Subwoofer Left

AVR LFE Mono Output ---(RCA or XLR)----> LFE Input
                                                                                                       XSP-1 Right SW output ---(RCA or XLR)----> Dspeaker Dual Core Right ---(RCA or XLR)----> Subwoofer Right


Hope that makes sense

Thanks again for your response again Gary!   Yeah, the DSDC (Dspeaker Dual Core) would not be used with the Sherwood R-972 Home HT setup at all. Just for the 2.2 setup.  Trinnov does an absolute amazing job on the subs.  If fact, if I could tap into Trinnov’s EQ without having to go through the Sherwood's preamp section I wouldn't even use the DSDC.

Besides the hookup sequence you listed, I think the DSDC could be inserted into the XSP-1’s Proc Loop.   The only negative to this maybe that the Left/Right speaker balance control feature on the DSDC may not work here like in a L/R signal path that you first listed.  In the Proc Loop, the DSDC would EQ the bass frequencies of the subs, and mains together.  This is the way that many use the DSDC in a 2.1, 2.2 setup.   It will auto-EQ the mains and the subs together at whatever frequency you want at 500hz and lower.   It also has a 16 PEQs that can be assigned anywhere from 20-20K, and using a number of slope choices.

The XSP-1+DSDC --I am beginning to see a number of exciting options .  The sequence you listed would EQ the subs leaving the mains un-EQ’d which I might like the best.

It still comes down to somewhat of a hard decision on what to do here.   I am still figuring it out, but I am leaning more and more towards the XSP-1.    The preamp in the Sherwood is one of the best I have heard in an AVR/processor…. period!   My DAC directly to power amp is only about maybe 3-5% more transparent than running the DAC through the Sherwood.    No one hears it, but me. But me is all that matters, lol!   But seriously, that little bit bugs me.

I think I would gain in transparency with the XSP-1, but at the expense of the loss of Trinnov’s various room EQs.  With 2.0, 2.1, 2.2 audio Trinnov can be activated, and it works extremely well.  But I have come to a point in my audio life where the pursuit transparency is the number one priority.   Thus, my interest in the XSP-1 for 2 channel audio and it’s HT By Pass capability.

I think that maybe the XPS-1+DSDC may be an unbeatable combination.  You can EQ all you need in 2 channel audio whether it be with your TT, DAC, Disk Player, etc., offering various degrees of EQ control in various situations otherwise not possible with other EQ’s in 2 channel listening.   I am aware of Dirac, but it is not as flexible as the DSDC as it only works with computers.
