I have two completly different question.
First, does anyone use ustec structured wiring panels? And if you do can you tell me if you have a panel with 8 video outlets but you have 10 outlets in the house, can you make a jumper from one of the 8 to the back input of the sat side to feed the other 8 in the can?

Second, On a subwoofer there are a left and right audio input. what if any differance would it have if i put a female rca y to 2 male rca connector on it, connected to the LFE output of the receiver?

If you only need two more outputs, just put a 3-way splitter on your last output and split it that way. I will probably degrade the signal though. Why do you need all 10 active? They actually have 10 TV's running? I only activate what is being used in the house to avoid a poor signal.

On your second question... I use the RCA "Y" cable to connect dual sub inputs all of the time. Depending on the sub, one input may be labeled for use with a single LFE output.

On the cable question, It seems that once a customer looks in the dist.can and sees the other coax wires just hanging there they get upset and want every wire connected.


On the "y" cable question, I am wondering if it has any advantage for splitting the one line level output from the receiver to one sub. therfore having one wire coming from the receiver into the "y" then pluging the "y" into the left and right inputs on ONE subwoofer.

on the sub question:

either input or both will give you good results. It is possible that the one marked "mono" may be marked so because its ground is different from the other, or maybe it is just so people who need directions will HAVE one here....

If you connect a single signal through a Y to both inputs, then the two signals will be summed, meaning that they will appear to be a single signal 3 dB hotter than if the signal just went into one input. The difference, then, is that
a)at full volume, you will be able to get 3 dB more out of the sub because you put 3 dB more in,
or
b)at full volume, you will be able to get more distortion out of the subwoofer because one input was just the right level to begin with, thank you,
or
c)you won't ever get it near full volume, you just will turn the knob up slightly less.

Of course, as an installer, you know that you can make some money on a nice gold metal Y connector and a six to eight inch Monster Cable...totally ripping off the customer if you do so, as this is NOT NECESSARY!

and adds no improvement, either

When I see a sub connected that way, I generally assume that the installer never thought to ask the question or look into the differences, not that they were ripping off the customer. But sometimes I wonder.

As a matter of general practice we always wire sub jacks in stereo...depending on the receiver you might have mono sub out or stereo sub out...I would say it's more dependent on the preamp you are using.
