Converting balanced signal to unbalanced signal from Bose HU
 

Bose HU pushes full range balanced line-level signal to the amp so you can't just connect a RCA plug to it.
Is it possible to use this product to convert balanced signal to unbalanced signal?

It uses 12 VDC so powering it is no problem. If this worked, it seems like a CHEAPER and BETTER solution than a sound processor like LC7i, or cleansweep. Because you are cutting down the "processing" part and getting clean and flat signal directly from the HU.

Not what you need, or are looking for. a simple LOC like the LCi2 is what you want.

So the LC2i accepts balanced/differential input?

so this wannabie uses TRS connection or?

some good read

No. the lc2 is a line output converter that will accept line level inputs from your bose stereo, or any other high output unit. A balanced line is not typically necessary in a car audio environment. They are typically used when the run between the source and the amplification is a great distance, where the possibility of noise introduction is greater than normal, or in a situation where noise interference is a problem.
That being said, given todays technology, noise introduction into a PROPERLY wired car stereo system is virtually non-existant when using good quality components throughout.
There are products out there, such as balanced line drivers and recievers, that pinpoint the problem, but In my opinion are a last resort to aid in the reduction of noises such as alternator whine (which can be resolved typically through proper component grounding).
In a nutshell, Install your system with good quality components and wire it properly, and keep it as simple as possible to achieve the end result you desire, then and only then would I suggest looking for other avenues to help you solve noise issues, If you even have any.

Just got off the phone with tech from AC. LC2i DOES accept balance differential input. Balance differential input is necessary in case of Bose system because the Bose head-unit transmits balance differential signal to the Bose amp. If you try to tap into the pre-amp signal coming from the head-unit using unbalanced RCA, you will get massive engine noise.

Anyhow, because of your suggestion of LC2i, I was able to find out a product that accepts balanced differential input. :tiphat: :ugh2: Thank you.
