input recording levels

Could somebody advise me on recording levels on my hi fi system when using audacity. I set me graphic equaliser to centre settings.I also have an independent bass control switch.Would I set this to zero setting or higher.Also would the balance be set to central or fully to left


Audacity just records the audio you send it, so set what suits you. Bass are the loudest sounds, so more bass may mean the recording will distort more easily. There is no distortion leeway with digital recording, as soon as the level is over the clipping level, audio above that level can’t be represented and is lost (as an oversimplification with most sound devices).
