Hello-
This is a MAJOR Newbie question. I searched forever on this topic for this combo of gear but couldn't glean any info from other threads...

I just got my Yorkville monitors in (!!) and I'm sure I will find a way to break them.. I don't want to have to wait until Monday to call the manufacturers, but I will if have to.

Here's the Question:
I find some apparently contradictory instructions in the manuals for the Yorkville YSM P1 monitors and my Edirol UA-5 sound card/USB box regarding Connections.

Your patience is greatly appreciated- you'll need it to read on....

Yorkville says that the cables to use ideally should be balanced. They say it is not required but everywhere I read that it is the ideal.

The specific question is:
From what OUTPUT on the Edirol UA-5/USB box to the Yorkvilles (YSM-P1)?

The Edirol manual says to use the Headphone jack to connnect to monitors. BUT the Yorkville manual says the signal must be Line Level. These are different, right? The Yorkville manual says Unbalanced can be used, but balanced is recommended.
The Edirol UA-5 unit itself has two 1/4" jacks that say "output". Do I use these jacks or the Headphone jack?

The Yorkville manual says that each monitor should be connected to a "single line-level" source; "e.g the Right or Left line output from a mixer or pre-amp. " Is this really telling me to use these R & L Output jacks from the Edirol?

I don't know anything about OHMS yet.
The OHMS are this:
Yorkville input impedance=10 K ohms... Input sensitivity= 1 Vrms (whats that?)

Edirol OHMS; Master out= 1 K ohm; Headphones = 50 ohm

The other confusing part is that the Edirol diagram picture of the Output 1/4" plugs coming out of the Right and Left "Outputs" have just one stripe (unbalanced?) The Edirol does not have any XLR outs but the Yorkvilles have the option for both 1/4" and XLR.

So If I use balanced plugs out of the Outputs on the Edirol- will they work? Do I plug the Right output from the Edirol to one Yorkville and the Left to the other Yorkville? Will that give me the full stereo sound I get from the headphones? This is the most confusing part to me. If I want to hear the real picture isn't the headphone the full stereo? The whole idea of using a right and left output from the Edirol soundcard seems odd to me...how is it separated?

One other thing. Connecting one Yorkville to the other - If indeed the Headphone jack is the right answer... I'd connect one balanced cord from the headphone jack to one monitor, and then one balanced cord between the two monitors to connect them? OR , somehow split off the signal from the headphone jack into two cords (balance or unbalanced?) and into each monitor.?

This is not the kind of thing for trial & error testing with my luck. I don't know if the Edirol and Yorkville manuals are truly contradicting each other but for my skill level, they are.

Thanks again for your patience.
 
Yo Alan:

Don't break the Yorks; there is probably a way to get to where you want to go.

I don't have powered speakers but I caught on to one part of your thread that said you were trying to connect to the Edirol OUTPUTS?

That doesn't click in my brain because you want to INPUT your speakers to your system.

If I got this right, and I might not, you have to run the signal into the powered speakers, then because they have their own amps, you should be able to hear something.

I use a Yam 2816 and it has two 1/4 inch outs on the back of the unit which I assume are for cables to powered speakers if I had them.

As is, I run my sound through the stereo outs INTO an integrated amp and the amp sends the tracks to my monitors.

Someone out there should have a better answer for you. Just trying to keep you from getting the axe out and chopping.

Green Hornet-
thanks

Yes, I thought that the soundcard which is producing the playback sound I usually hear through my headphones,

would send the signal to go OUT to the monitors

Thanks
 
i have never used the Edirol, but i'll try to help you out here.

working our way to your main question:

1. V-rms is "Volts, RMS". RMS stands for Root-Mean-Squared, which is one measurement of the power of a signal.

2. Ohms are a measure of resistance/impedance. More ohms = less current. When connecting two things, you never want the source impedance (i.e. an amplifier) to be greater than the load impedance (i.e. speakers). If this happens, too much current will flow through the amplifier and that is not a good thing.

In your case, your source is your Edirol's output, and the load is the input on your monitors. Your monitor's input has an impedance of 10k = 10,000 ohms, and your Edirol's output has an impedance of 1,000 ohms. You don't need to worry about anything.

3. I guess i somewhat implied this in #2, but you should connect the 1/4" outputs of your Edirol to the 1/4" inputs of your monitors. The edirol manual probably refers to "monitoring" through the headphones. This does NOT mean you should connect the headphone output to your monitors. Use the line level outputs.

4. I would venture that the edirol has unbalanced outputs. The fact that it offers RCA outputs, as well as the fact that it operates at -10dB, make it seem like it is unbalanced. This doesn't mean it won't work -- like your yorkville manual says, it's just not ideal. There is a possibility that a small amount of noise could be introduced to the signal, especially if you use long cables to connect them. So unless you find out that the edirol's outputs are balanced (TRS), you should use unbalanced cables.

5. The yorkvilles do not connect to one another. Balanced cables look like headphone plugs, but they are NOT stereo. they only carry one mono signal per cable. The left channel goes to the left speaker, and the right channel to the right speaker.


In summary, here is what i would do: Connect one 1/4" cable (UNbalanced, unless you discover that it has a balanced output) from the 1/4" right output on your Edirol to the 1/4" input on your right monitor speaker. Connect your edirol's left output to the left monitor speaker.

Unless you turn everything on at a ridiculous volume, there is really nothing that you could break, even if you plug things in the wrong places. You are only dealing with line-level signals, which in the scheme of things, are not very powerful.
 
jrosenstein-

Well, I'm just about to go on a vacation and have been trying to finish the tracking on this one other song thats driving me nuts and dominating my all my music time... so have not bought the cables and tried the monitors yet! I have two finished projects all ready to mix too - aaarrgh - Not enough hours in the day !
Thanks for asking. I will share when I get it all up and running
