Re: [LAU] how to record Gramophone?

If you get this wrong you could have little signal or significant colouration. At some point in the chain you will need EQ to balance whatever was applied during mastering. For modern records this is the RIAA curve and is usually built in to turntable-specific pre-amps. These days it would be possible to do it in software and this may be the better approach if you are interested in really old recordings which use some non-RIAA curve. Either way you'd want to know if the pre-amp includes the RIAA curve or not. Much depends on which soundcard you are using. For consumer cards the GNOME volume control applet normally allows most things to be adjusted but not all available controls are visible by default. If you can't get what you want with the visible controls try Edit/Preferences where you can chose which controls are visible. ALSA normally starts with everything muted though once you've set the controls hopefully they are remembered. For pro cards there is sometimes a separate program required to load firmware, configure the card and set it's mixer settings. For example the RME HDSP family have hdspload, hdspconf and hdspmixer. Hopefully this helps, if not it would be useful to know the hardware/software combination you have settled on so people can offer more specific advice. Steve.
