NSM Performer wall speaker polarity

[launton]

Hi all

Just bought one of these but could do with someone having a look at the included picture and telling me if it's correct.  I don't want to damage my speakers or system with incorrect polarity.  The manual shows a 'triangle'? on one terminal but I don't know if it's meaning + or -



Thanks, any help would be brilliant as I don't want to damage my jukebox or speakers

the triangle shows the positive.

P.S. - having reversed polarity will not harm speakers, but it will introduce a cancellation effect since the wave will be reversed.

it's quite common to reverse subwoofer connections when the output is being reflected off a wall so the wave actually ends up being back in phase again after the reflection.

Thanks for the speedy reply!  That's perfect.
