Sorry I meant the DXR12.
However since tinkering further, I found that I got a better sound from the 1/4" jack set at an instrument as opposed to XLR at mic.
Yamaha set to receive at Mic level....it however sound better with XLR line to line but not as good as 1/4" jack instrument.
So it as it stands, the best sound I get is from the 1/4" out at instrument level into a Yamaha monitor set to mic level (albeit that doesn't come into play as that only effects the xlr input) .... but when comparing with my studio headphones and studio monitor both of which sound pretty much the same, the Yamaha DXR12 definitely sound a lot different but I'm guessing that is something to do with it being a PA system speaker and the nature of the eq of the speaker maybe amplifying certain frequencies which are prob more tailored towards vocals.
At this stage, I'm guessing your going to tell me to either get FFFR speakers (like the line 6 and run them as a PA speakers to FOH) or I'm going to have to either tweak the global eq or eq on the mixing desk to try and smooth out??
