Received my new Marantz SR6200 at the weekend (£386 from Quality Electrical Direct) and Ive got a quick query for anyone else out there who has one. (Likely to be the first of many given that the manual is useless, and Im new to home cinema!) From the first time I switched it on there has been a red speaker symbol on the RHS of the display which (surprise, surprise) isnt mentioned anywhere in the manual. Anyone got any ideas? Im using Mission M73s at the front; the centre/rears havent arrived yet. Could it be because the amp is 110 wpc and the speakers should only be driven up to 100 Watts? I assumed this wouldnt be a major problem. Im also having to turn the volume to about 25dB for normal listening, isnt this a bit high?
