Re: How to hook up PODxt to PA?
Let's break it down!
1/4" is the diameter of the plug - the standard guitar cable size
Balanced, put simply, is a way to transmit an audio signal that eliminates most outside interference and noise. It uses a three-conductor cable (see TRS) as opposed to the standard two-conductor guitar cable (which is called an "unbalanced" connection). It's ok to plug an unbalanced cable into a balanced jack, but it will probably be noisier over longer distances.
TRS stands for Tip Ring Sleeve, which means the plug is split into three sections. If you look at your guitar cable's plug, it probably has two sections (the tip and the sleeve, aka. TS). TRS has a third section in the middle. This is done to accomodate the balanced connection (see above). You can plug a TS cable into a TRS jack, and vise versa, with no problems.
+4dBu is the level of the signal coming from the POD. This is a line-level signal, which means it can be hooked directly into other line-level equipment, such as a mixing console or a recording device. There are two levels of line level signal: +4dBu (the professional standard) and -10dBV (the semi-pro or home audio standard). +4dBu is a "stronger" signal, and is capable of traveling longer distances without degrading.
So what does that all mean for you? It means you have a few good options for hooking the PODxt to the PA.
Your
best option would be a balanced connection direct to the board, if the venue's hardware supports that. A good mixing board will have 1/4" TRS balanced jacks on at least a few of the channels. To do this, you will need 1/4" TRS-to-TRS cables that are long enough to get you to the board or the snake.
If they don't have a balanced connection for you, you can use the TRS-to-TRS cables anyway. They will work fine with an unbalanced signal, and that way you still can have the cleaner balanced signal when you play somewhere that can accomodate it.
Anyway, my recommendation is to get a pair of decent quality TRS-to-TRS cables that are as long as you can afford.
