7.2 Sub out question

[langn08]

So, I was looking at the new Yamaha receivers and I have a question on the 7.2 receivers… They have two outs for subwoofers but why not just use a Y cord? Does it provide you with something that a Y cord could not give you? I just need to understand why you would pay the extra for the additional sub out.

They're just saving someone buying a $4 cord and then charging more than that for the feature. But then alot of people wouldn't know to just buy a Y, think they have to have the two sub outs, so they buy it not knowing any better.

The only benefit I see to two sub outs is a higher preamp voltage on each output. When you use a splitter the voltage gets reduced which means more noise if you can notice it and slightly less power from the subs as the input signal is weaker. A Y splitter would do for most but if someone has a low end amp it probably has a low voltage sub out. Higher end amps should have higher voltage sub outs allowing for easier splitting.

some people like me. want a designated left and right sub out. thats why I have a 7.2 YAMAHA 663.
4 subs one in each corner of the room. 7.4

I had no idea they separated them with Left and Right but it makes so much sense. That has to sound so much better than a single sub or an amp with a splitter.

Also, if you are using different brands for your subs or different series, you can callibrate both subs individualy using the reciever. Otherwise you would have to rely on the same exact settings to be right for both subs.

Thanks for the quick responses on this! I am expecting my second sub in the mail tomorrow and will be using a Y cord... I am assuming I will have to turn up my sub on the receiver side to compensate for having two subs hooked up.

The conventional wisdom had been that sound at that low frequency was essentially non-directional, which is why there was always a 7.1.

Can you REALLY tell the difference, practically?

Yamaha states that the signal output at sub one and sub two outputs are the same. How do you get left and right channels please?

"WHAT" how can they say it's a 7.2 system if it's only 7.1 the sub outs are mono?
the receiver says sub out 1 and 2. "HOLY S**T" that's just wrong

With a Y splitter the circuit is a parallel ckt. The voltage is constant through each branch, the current is what becomes variable. A receiver could have two seperate pre-outs for the subs, unlikely, or be a built in splitter, most likely. For the money I would get a y splitter.
