I have the following system set up:
Denon DP-30L Turntable/Yamaha RX-500/U Stereo Receiver/Dell Optiplex 755 Computor with Windows XP pro/DJ-Tech RCA-2-USB PnP Audio Device with Software/Magix Audio Cleaning Lab MX Software.
When I play an LP the Audio Cleaning Lab software tells me the Audio input is too low. I slide the Audio input volume to maximum record and the screen shows a thin band with peaks and valleys on the screen. The recording level meters show the recording level at about -25/-30db.When I play the result back there is a humming noise which is mixed in the the music. When I clean the recorded track on the Audio Cleaning Lab software it does not totally get rid of the humming sound. I also tried normalizing the recording but got the same result. I also diconnected the Turntable ground wire from the Receiver to cut down on humming.
How can I increase the Audio input signal without setting it to maximum volume? Is my Receiver good enough to do the job or do I need to use a phono preamp in its place? Is there anything else I can do to make this function correctly?
In the good old days, amps came with a pre-amp built in precisely because the output from a record deck was so low. Modern amps tend not to have them - so I make the posters who have recommended a pre-amp about right.
Looking at the manual for your receiver - RX 500/u manual - it does have an input for the turntable so I should think that there is a pre-amp built in. You need to use a line level output such as the Tape 1 as that should give the correct output levels and is not affected by the volume control. This should be connected to the Line in on your computer. Hope this helps you.
