What Is The Best Way To Get 7.2 Out From A 7.1 Avr

[dham]

I am sure this must have been discussed somewhere here before but could not do a search easily to drill down for fewer threads .....

What would be the best way hook up 2 subs to one RCA out on the Pre/Pro/AVR?

1. One to Two RCA split cable?

2. Some kind of an EQ like SVS EQ? Does that actually allow to do it?

3. External Amp?

4. Bite the bullet and buy a new 7.2 Pre/Pro?

4. Or any other options?

Any feedback is much appreciated

Cheers

Get a "Y " adaptor....no need for a new pre ( are the subs passive or active based ? )

[dantan]

I reckon option 1. My brother-in-law did this a year or so ago and works a treat, and is the cheapest option, which is a bonus!

Despite the number of subs it is still just a .1 channel so what you here from each sub is essentially the same source anyway.

Go the Y splitter - think I got a nice one from C-link once???

Do any of the new AVR's actually output (or are capable of) a stereo sub mix - ie .2?

I'm guessing no, as all source material is still just .1 anyway?

Thinking out aloud here really

Thanks Ken, Dan and Jutta.

For a change the cheapest is the best

Just thinking ... Will the option 2 allow to calibrate the 2 subs separately via the SVS EQ?

Cheers

The SVS can calibrateand EQ each sub independently. Option 2 is the best way to do it, option 1 is the cheapest/easiest. I'm using option 1 myself, until I can get a good deal on the SVS unit.

I agree the Y splitter is the simplest.

Depends on how "perfect" you want it to be, as the Y splitter approach will assume the subs are equidistant from the listening position. Also, depending on the sub's tuning capabilities, phase alignment could be more difficult as many of the AVR use "distance of Subwoofer to listening position" as a means to adjust phase response.

Yes, the SubEq will allow you to better eq and integrate your subs into your system.

In reality many people have used the Y splitter approach for many years and have not had problems.

My 2 cents.

are the two subs of the same type?

I have two similar subs, similarly located to the general viewing area (one underneath the left channel, the other under the right channel). A simple Y cable works well. Especially with 50 year old ears.

That is what I thought Hakka. The picture of the SVS EQ back pane has Input A B and output A B and I thought you need 2 channels input to get 2 channel output. I suppose you can use a Y cable and split the input ?

[betty boop]

without a 7.2 avr/pre. Y splitter is one way. but if your subs actually have a loop out then I would loop one sub off the next.

Yes the subs will be exactly same and will be placed pretty symmetrically .....

I guess begin with a Y cable and add an EQ if not happy ????

Good point .. that is another option too ...

I actually have to check that ... I am talking about the subs I don't have yet but will be coming pretty soon:)

You can just connect to one input and have 2 outputs, the SVS will split the signal so no need for a Y splitter.

Just realised I made a mistake earlier, I'm not using a Y splitter I have a Behringer MX882 Ultralink Pro splitter/mixer. I used a Y splitter before I got that.

I'd add an EQ anyway, it will improve just about any sub. There are cheaper options than the SVS, I use the Behringer Feedback Destroyer DSP1124. They are on ebay for $200, you could probably do better through one of the DJ supplies online stores.

Cool ... That is smart EQ POV.

But you still prefer/like to add an SVS EQ?

Yes I'd prefer the SVS but I dont really need it. My receiver has Audyssey MulteqXT so that EQs the sub and I then use my Behringer EQ to boost up the low end a bit and smooth out the crossover.

The Audyssey in the SVS EQ has double the resolution of the Audyssey in my receiver, and the ability to set different distances for each sub. I have 2 subs that are symettrically located and the same distance away from me so I really wouldn't benefit from it much at all. It just looks cool and I like buying stuff

A 7.2 AVR really is just a 7.1 AVR with the splitter on the inside of the chassis (as far as I'm aware)

As others have said, one output into the SVS EQ and two outs for the best sound/EQ response.

But for now a $30 splitter will be pretty darn good.

And also stated, try to position them equally from your listening position.

jutta, some 7.2 avrs/pre's eg the denon avp do allow full and discrete setup of dual subs. and in various configurations L&R, both LFE or if running upto 3 subs can do L&R and LFE.

as mentioned dont have to spend the $30 in a splitter if your sub has outputs as will allow daisy chaining.

Sweet

Splitter might be easier if subs are wide either side of a central AVR but yes I get what your saying.

I've done option 4. myself but option 2. works an absolute treat and would be better than option 4. Options 1 and 3 still need an external EQ/crossover/DSP to work properly.

Thanks Gior...

As I said option 1 and 2 are what I am leaning towards .... though I think if I don't do option 2, I wouldn't know what I may be missing ....

Now.. Hakka threw another spanner in to the mix ... I have to check other sub EQs available in the market ......
