on the back of the ceres C4.5BT, is the sub out port mono TRS or stereo TRS? I can buy a cable for a subwoofer in either mono TRS to mono RCA or stereo TRS to dual (left and right) RCA, which should I buy? Many thanks

(the sub has both left and right inputs for RCA, although i understand i can just use one of them, i would prefer to buy a stereo TRS cable - if that's what the out port is on the ceres - and connect it to both left and right of the sub. there's no point, however, if the original output is only mono and way)

incase it helps others, i contacted customer support and it's mono

For reference, in the Pro Audio world, trs is mono, balanced. For a stereo signal, it uses 2 channels, unlike home/consumer audio that passes left/right via one cable.

ah ok, thanks for the info. so how come you can buy stereo TRS to dual mono RCA cables?
