XLR? not true. gold plated, balanced trs cables have a better sound and actually compliments the bx8's technology. that said, you can get cable that is trs-balanced on one end and rca's on the other. then just get a "Y" right-left rca into a stereo 1.5 cable. easy and cheap. but using xlr's for output? NO. save those for your input MIDI instruments and controllers.

M audio studiophile BX8a deluxe has very hot back panel when on after a few minutes

There is a problem with the amplifier internal to the unit, most likely from the main power transformer. Return to the place of purchase, or a service center for repair/replacement.

I have a pair of m-audio bx8a deluxe monitor speakers. I need to know how hook my iPhone up to them or just one of them. I tried using a adaptor and plugging into the trs input but the music is distorted....

The conection you made is not quite right. This is because the TRS (and the XLR) connectors at the back of the BX8a are for balanced signal. You have to use either this cable or connect both middle and ground point of the TRS connector at the ground. In other words the ground from the ipod must be connected with ground AND middle ring of both BX8a and the ring of the ipod must be connected with on BX8a TPS tip and the tip of the ipod must be connected with the other BX8a tip. I don't know if you are familiar with soldering connectors, in this case post me back to make a schematic for you with the connections.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Hi David

The fault may be the bass driver itself or the Low Frequency power amp built into the speaker box. hard to determine which it is because it is intermittent. There are a couple of things to try. when the fault occurs.
  1. just lightly touch the cone on the bass driver see what happens. If it fires up again, it has failed soldering on the spider wire connections from the terminals to the cone. This can be repaired by a decent sound guy the does speakers, or a specialist near you that can be found easily enough. A new replacement driver is also an immediate option if you don't mind spending the bucks.
  2. if the above didn't work, to prove to yourself where the problem may lay, you could swap the bass drivers from one box to the other and see if the fault follows the driver, or remains with the speaker box. If the electronics are faulty, unless you have some decent experience with soldering and fault finding, you may be best to get it to a repair guy,
If you cant get it sorted, please provide me with your location(not address:)) and I will be able to locate a decent guy that knows what he is doing for you. Cheers

Woofer not working on new bx8a speaker

Hi ermo

Your new speakers are BiAmped, and if a woofer is not working then it is probably a fault in the amp or connection for that woofer, or the the woofer itself has a problem. If they are brand new, I suggest you take it back to purchase point to get sorted out. There is nothing that you can do that will NOT void your warranty. If you do not have a warranty, then get back to me here and we can work through the problem. Cheers

Connect BX8A speaker to PC

Hello waddragon,

First, let's start with the BX8a. Those are powered speakers (built-in amplifier in each) so, you do not need a pre-amp. What you need to connect them to your computer is a 3.5mm to XLR cable OR a 3.5mm to 1/4" TRS cable, also known as 3.5mm to two 1/4" mono plugs (the back of the BX8a has inputs that accept either type). Cables are available at most any electronics stores. Make sure you buy a long enough cable to run from the back of the computer to where the speakers will be.
It sounds that you only have one BX8a which means you'll be listening to only one channel of the stereo output. In any case, make sure before connecting the speaker(s) to the computer that speaker power is off and volume control is at minimum. Connect the 3.5mm cable end to Line Out 1 jack of the X-Fi sound card and either the XLT or TRS ends to the speaker(s) input(s). Play some audio content on your computer, turn on speaker(s) and slowly increase volume to a safe level. Everything should work fine.
Let me know how it goes.
