Best type of RCA splitter to use?? - Page 3

post #31 of 39

Thanks for that. I'm surprised that it's so hard to find a high quality RCA matrix box available. You'd think there would be a decent market for that, for a reasonable price.

Check out the Maple Tree Audio LR1 Line Router $180 any combination of up to six in/out ie 1 in 5 out , 3 in 3 out etc

I suppose it depends on your degree of audiophilia nervosa.

 

Analog switch
Some unsorted examples from my archive:

At last count, Acoustic Sounds had some NOS units; however, they all retail for $1650.00 now. Manley has stopped making them, but if you call the company, or can navigate eBay, they setup an eBay store whey they were (and maybe still are) selling the last 5-6 units directly.

Thanks heaps for the responses! It looks like there are some other switch boxes out there I haven't known about before.

Serious question - it seems like my post about my contact with Schiit was ignored.

Schiit customer service said that splitting the signal off a DAC with simple, cheap splitter cables was fine and would not affect the signal.

Yet everyone seems to be posting about $1000 splitter boxes.

 

Why? What am I missing here? Do you guys not trust Schiit or is there some other reason?

Nothing against Schiit - but as far as I understand, an analog signal split into 2 will unavoidably lose some of its power.

 

Also, I'm looking for a 2X4 solution at least (a 2 source, 4 output grid) - so a Y splitter is also not relevant for me for those reasons.

 

A splitter box (whether a 20$ or a 1000$ one) will be electrified and should keep all the signals at their original strength.

Well, leaving this at the 2 way split, Schiit directly said that there will be no effect on the signal.

I'm not hating on other peoples buying decisions, I'm just wondering what would underlies the 1000-dollar box in the face of an engineers advice to the contrary.

This has already been explained.

 

Provided that both input impedances are sufficiently high and more or less equal if you split a signal into two there will be no loss of signal quality but the strength will be halved. Resulting in a 3dB loss. So if you keep on doing it eventually it's going to effect your S/N ratio. The convention is you can safely split up to 3 times provided you have sufficient gain available. Which you probably have. Extra cable length may also lead to noise if you have a ground issue.

 

Unbalanced line level splitters (and combiners) are rare. You can see the problem. Connecting together the grounds on several consumer grade appliances spread over a wide area is almost certain to lead to ground loop issues. That is why professionals use something called a distribution amplifier for this task. It not only splits (or combines) a signal it also converts unbalanced to balanced and provide a small amp per channel to adjust the gain. You can get cheap ones from the likes of Berhinger and ART or top of the range from Drawmer and Radial.

I still think that if the OP has the cash he would do best with a basic audio interface which is designed for the task in hand. And many other useful functions. You can get a 2 in 2 out unit with headphone from around $150. better would be 2 in and 4 out which starts at ~$200. If that's too steep then stick with a simple Y lead for now and hope you don't get a ground loop.
