Axiom Home Page Forums General Discussion Technical Questions voltage difference between soundblaster and amp

Hello everyone,
being new to this message board I took the time to explore a great many posts but I was unable to find anything that had anything to do with my problem. I have a sound blaster live 5.1 with a digital out (a headphone 3.5mm? jack) on the back. I want to connect this to my Denon 1403 with an RCA Coax in on the back. I connected a mono headphone sized jack into the back of the soundcard and connected it to a single RCA in which I plugged into the back of my reciever. This gave me digital sound no problem. However in my readings on the net I discoverd that this could actually be harmful because apperently the sound card puts out 5 volts of power and the amp is built to accept 0.5V. If this is true then I'm pumping in 10 times the volts that I should be. Can anyone tell me if this is true or if I'm safe. I'd rather not screw up my card or reciever. Thanks to anyone who can offer any help.

Russ,welcome. I haven't attempted to verify those numbers that you mention, but if the soundcard output is being handled without audible distortion it would seem that there's no problem. The typical maximum output for a player, for example, is 2.0 volts. A higher output would merely call for a lower setting on the 1403's volume control.
