Behringer P16 versus Aviom

There are actually two wiring specs that will result in a straight through connection, 568A and 568B. In most cases, either scheme will work just fine. A crossover cable is wired to 568A on one side and 568B on the other.

I've always thought that so long as the same wires were connected to the same pins on both sides it didn't matter too much which wires were actually used. I believe I may need to test my CAT5 cables before use from now on.

It makes a difference. The twist of wires making up the pairs and the lay of the pairs affect cable characteristics and each pair must be terminated at each end as a pair. Unpaired termination, even when "the same," end-to-end, will impair the ability to move data.

+1. If you are only going a few feet its not a big deal but for longer distances the twisted pairs need to be used as designed for the properties they impart. Been there, done that.

It was not the cables, as the cables used were the cables provided. It was the P16D and those surface mount jacks. They should have put Ethercons on everything and made it robust. I wouldn't mind a bump in price for better connectors.

This is my only beef!!! Apart from that I love these thing for sure!! They sound great, get loud and even old crusty jazz dudes in our local musical orchestra got into them pretty quick. The one thing i have done with ours is make sure I have a choice of single sides headphones as well as normal headphones, the above mentioned jazz dudes used the single sided ones and where quite happy!!!

Dear Guys,
This is John with BEHRINGER, I wanted to offer my support with any P16 questions. I have had extensive experience with these in both studio and live environments, having been lucky enough to have my system for over two years now. Let me know if I can help in anyway.

Best,

Re: Behringer P16 versus Aviom

Anyone come up with a labeling template, say for Word or Excel? We could use, as we just got them, and the users are asking. We have cheat sheets for now, but sticky labels would be great...

Dear Gayle,

I like to use a P-Touch labeler. They come with layout software that make it super easy to make custom labels for the P16-M.

Hope it helps.

It doesn't matter. You are correct.

The only time it DOES matter is when you are putting ends on the Ethernet cable yourself. Then you need to know which way the other side is wired.

What does matter is that the wires are twisted pair, although not exactly for the reasons Tim described. All ethernet cables are twisted pairs, although there are differing specs regarding the packaging, shielding and wire type used that differentiate them.

Twisted pair cable is used because on the receiving end, each wire goes into the (+) and (-) inputs of a differential operational amplifier. If noise is picked up on either wire, it is inductively picked up on the other wire as well. Since the output of the op amp is the difference between the two wire voltages, any noise is then simply subtracted out leaving only the original signal. Signals are transmitted on twisted pair by raising the voltage on one line while lowering the voltage on the other. At the other end the difference is read as a high signal or a "1" in digital terms.

It matters 100000% for the exact reason you just described.

Re: Behringer P16 versus Aviom

I've begun to regret my previous post. The more time passes the more stupid it makes me look.


Well, not the dumbest thing I've ever said in public. Certainly not the last one either. I'll make a donation to make up for embarassing myself.

Silas,

The 568A and 568B specs is what I was referring to. Of course I believe that the pairs must be used and wired correctly. It just doesn't matter if the cable uses A or B spec since pin 1 on one side still goes to pin 1 on the other side. I was not trying to say that it doesn't matter of you don't use twisted pairs for your signals.
 
Re: Behringer P16 versus Aviom

I am in need of a bit more detail as to how the P16-M handles tone
control settings across different channels. The manual implies that
the tone controls affect the actively-selected source, i.e. channel
1-16 or 'Master'.

First, I need to verify that this actually the case. Are the tone
controls remembered by the current selection OR are they always global
like the master level control?

If the tone controls are source-specific:

- When are they "read" by the mixer logic? If I have channel 1
selected, turn the treble all the way down and select channel 2 I'm
assuming that channel 2 inherits its previous state. But, with the
treble control still physically counter-clockwise what makes channel
2 "read" the knob state? Does it pickup the new state when ANY of
the tone controls are moved? Is it picked up on a per-knob basis?
Other?

- I notice that the LED rings at the base of the tone controls
illuminate in different patterns depending on what input is
selected. What is the significance of this? Is to flag the fact
that one or more controls was moved from flat for that channel?

- If I have been making tone adjustments on channel 1, then switch to
channel 2 is there a way to determine what the memorized tone
settings are for that channel? Can the LEDs provide a clue?

I've discovered by experimentation that the pan knob can always be
automatically centered by pushing it and the master volume can be
muted by pushing that control. Neither of these behaviors appear to
be documented. Are there other handy features that are similarly
not mentioned?
