Question on Luxman L-AX550ii balanced inputs


Hi all.

I've been googling like crazy all day, and I cannot seem to find an answer to this simple question.

What is the MAX input voltage that the balanced inputs on the L-550AXii can handle? (Ok, maybe not simple.)

I'm looking at a source that puts out 5.8 volts max, and I'm concerned that that might be bad for the amp.

I've written Luxman, but I don't know how soon they'll get back to me, and I'd really like an answer.

Thanks!

Go to this page, and at the bottom there is a button to download "catalog".

Then go to the specifications for the Luxman CL-38uC and read footnote 2.

I was unable to post a direct link to the "catalog' in pdf

Have a great day.

Hey @jperry -- I did already see that, and I read the footnote. I wasn't saying I didn't believe you. I was trying to say that it seems that having such a low max voltage on the balanced input seems (to me) as if it's making the amp operate under a handicap.

I'm really new to the whole balanced input/output thing and there seems to be more to it than "hey, just plug it in."

Thanks @dasherma

As I said I think it is to pair with the Luxman CD players. If you look their out put voltage is 2.5 V

The Cl-38uC is a different circuit than the 550AXII

The CL states: BAL.LINE: 190mV/20kΩ *2
