Don’t tilt or bend the column speaker

Loudspeaker wiring

GP18A

Once assembled, the 24×2″ column loudspeaker (composed of three modular 8×2″ columns) is directly driven by a dedicated channel of the amp module of the active subwoofer: the speaker connector is implemented in the column joint and no other wiring is necessary.

GP18

The GP18 passive subwoofer and the loudspeaker column can be driven by a GP18A active subwoofer or a KGEAR amplifier like the GA46. Since the speaker connector is implemented in the column joint and no other wiring is necessary, once assembled, the 24×2″ column loudspeaker (composed of three modular 8×2″ columns)
is directly driven by an internal wiring from the speakON connectors on the rear panel. SpeakON A and speakON B are  connected in parallel in order to make the  signal pass through (see picture below).

SpeakON A

| +1 –1| column
+2 –2| subwoofers

SpeakON B

| +1 –1| column
+2 –2| subwoofers

Active+Passive System

The GP18A implements a 4-channel amp module with DSP: a single GP18A active system can drive up to three GP18 passive systems in stereo mode.

By default, the input signal shall be fed with a pair of cables connected to the XLR Combo balanced input channels 1 and 2 on the GP18A active loudspeaker rear panel. If only one cable is used to feed the input channels 1 or 2, the double mono configuration can be set with ArmoníaPlus.

Stereo pair system

Once properly assembled, use the 15m (49ft) speaker cable provided with the GP18 passive loudspeaker to connect the speakON B connector on rear panel of the GP18A active loudspeaker to the speakON A connector on the rear panel of the GP18 passive loudspeaker.
