Audio input connections

The audio signal input is to connect, up to your own choice, whether to the XLR inlet or RCA
inlet.
The XLR inlet permits the connection of a source with symmetrical signal and uses standard
wiring instructions:
Pin 1 = Ground (shield)
Pin 2 = In phase voltage ("hot")
Pin 3= Out-of-phase voltage ("cold").
The RCA inlet permits the connection of a source with asymmetrical signal. It's common to
link the out-of-phase voltage (Pin 3) to the ground (Pin 1). This connection is generally made
at wire level.

Tweeter phase plug

The CMS speakers are delivered with grilles for woofer and tweeter. In order to optimize the
sound stage precision, we advise you to remove the grilles thanks to the hook included in the
packaging. Then, install the phase plug on the tweeter in the vertical position by gently push
on the suburbs of the phase plug (see below).
