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!

You state that your source has a max output of 5.8v. 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! 

 

Thanks @nwres.  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.

I owned and loved the 550AXII before upgrading within the lineup. It is very robust.

What is your source component?
