Splitters
« on: March 09, 2015, 03:52:00 PM »
What do people keep on hand for splitters?
For those times where there is no Patchbox available and more than one person wants the SBD feed?

I'd like to know about splitters too - are there any downsides to doing this to a signal?

Not if you use a good splitter.

I bought two Split 6's from Justin at ProSound. (B&H link here just because it came up first) http://www.bhphotovideo.com/bnh/controller/home?O=&sku=351514&gclid=Cj0KEQjwifWnBRCB5PT57KSVw-kBEiQASV7aRB_VpwnP02UgU1SMJF-twc893HJr0xIlAoAHqJbyzt0aAkKm8P8HAQ&is=REG&Q=&A=details

Signal is identical for each of the 6 split feeds. Quite useful, especially at a local venue where lots of video guys like to go...

I'd be very interested in these. Still love the cables you sold me last year.


What do people commonly carry with them?

Santorum and I use splitters all the time to share the soundboard feed at our favourite recording venue (XLR > XLR).   Never had a problem.  Not sure where he bought them, though.

The ones I bought were Hosa brand and I got them through amazon.com.  I think they were around $15 for the pair.

Thanks.

I generaly use this cable for SBD patches:
http://www.amazon.com/gp/product/B005HGM1D6/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

I carry some XLR adapters for those times where the board doesnt have 1/4 out.

Is it acceptable to use this:

http://www.amazon.com/gp/product/B000068O1B/ref=ox_sc_sfl_title_4?ie=UTF8&psc=1&smid=A34VCPZVL7E6XQ

And get some splitters from there?

What about signal loss?

I had ted make me a 2 foot XLR to XLR splitter, never had an issue and quality work. Use it for the board feeds so I can split it with the band recording, FOH recording rig or other tapers. Someone told me there is a 3DB reduction due to the split for each side of the split XLR.

Thanks jon for clarifying.

That's not true, it depends on the source impedance and load impedance of each split:

Zloadtotal = Zload0 || Zload1 || . . . Zloadn
where "||" means "in parallel with", or = 1 / (1/ZLoad0 + 1/Zload1 + . . . 1/Zloadn)

compared with an open circuit:

dB loss = 20 * log ( Zloadtotal / (Zsource + Zloadtotal))

or compared with a single load:

dB loss = 20 * log (( Zloadtotal / (Zsource + Zloadtotal)) / (Zload0 / (Zsource + Zload0)))

Such that if you have a 100 ohm source and 1K ohm loads, then compared with open circuit each added load yields:

1 -0.8dB
2 -1.6dB

So the loss from the first split is -0.8dB, subsequent splits vs. open circuit are:

3 -2.3dB
4 -2.9dB
5 -3.5dB

into *each* load (that is, every load will "see" a signal at that level).  Thus, the loss gets greater in total, but smaller compared with the previous split.

If the nominal loads are more typical 10K line inputs, the loss is much smaller:

1 -0.09dB
2 -0.17dB
3 -0.26dB
4 -0.34dB
5 -0.42dB

The person giving that advice may have been confusing what happens with speakers and power levels, which actually increase 3dB in total power as you double the count of speakers (of the same impedance), assuming your amp doesn't melt, just like adding more light bulbs in parallel in a room makes the room brighter, except for a tube amp which is more complicated as its source impedance is higher as tube amps are designed to match impedance to maximize power transfer so you have to switch output transformer taps for various loads.  Man, that was a long sentence.

Most of what I have gotten for patches have been 1/4. I carry XLR adapter just in case the outputs aren't 1/4.

With that in mind, would a pair of these be sufficient?

Would there be any signal loss with these?
