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!

Does that mean your source has a variable output? If so, try it turned down low. The manual states: Pre-amplifier Input sensitivity/input impedance LINE : 180 mV / 47 kΩ MONITOR : 180 mV / 47 kΩ BAL. LINE : 180 mV / 55 kΩ Someone more knowledgeable may be able to assist with the math. Good luck!

The source does not have a variable output unfortunately. I don't understand the math behind figuring the input voltage -- I have heard (but only on the internet) that a balanced input can generally take up to 10 volts input, but I'm not sure how much to trust that figure.
