Reply to "MTH PS1 Gas Turbine Conversion to ERR TMCC"

John,

Is the Railsounds board labeled + and - or does that connector not matter as long as the speakers are connected + and -?  I have run a few old MTH speakers to the Railsounds board and I have not paid attention to polarity.  Am I correct in thinking the polarity only comes into play with multiple speakers?
