Installation

Mains voltage

After having unpacked the unit, first check that the operating voltage is correctly set (see location on
rear panel). If it is not, adjust the selector to the appropriate position. Also check and if necessary
replace the fuse, which rating depends on the operating voltage (please refer to technical specifications).
Your products must be earthed using the power cord supplied. 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).
