Assembling instructions

Set the 8×2″ GC52 column speaker on top of the 12″ subwoofer using the column spacers to reach the desired height, as shown in the picture below.

In order to disassemble the system, please take care to unplug each module pulling up the column vertically.

Don’t tilt or bend the column speaker.

Loudspeaker wiring

GP12A

Once assembled, the 8×2″ GC52 column loudspeaker is directly driven by a dedicated channel of the amp module of the active subwoofer: the speaker connector is implemented in the joint of the column spacers and no other wiring is necessary.

GP12

The GP12 passive subwoofer and the loudspeaker column can be driven by a GP12A 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 8×2″ GC52 loudspeaker 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).

Connector	Terminals	Transducer

SpeakON A

| +1 –1| column
+2 –2| subwoofers

SpeakON B

| +1 –1| column
+2 –2| subwoofers

Active+Passive System
The GP12A implements a 4-channel amp module with DSP: a single GP12A active system can drive up to three GP12 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 GP12A 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 15 m (49 ft) speaker cable provided with the GP12 passive loudspeaker to connect the speakON B connector on rear panel of the GP12A active loudspeaker to the speakON A connector on the rear panel of the GP12 passive loudspeaker.

Stereo quad system
Assemble one GP12A active loudspeaker system with three GP12 passive loudspeaker systems in stereo mode.

Left channel: GP12A + GP12
Use the 15 m (49 ft) speaker cable provided with the GP12 passive loudspeaker to connect the speakON A connector on rear panel of the GP12A active loudspeaker to the speakON A connector on the rear panel of the GP18 passive loudspeaker.
Right channel: GP12 + GP12
Use the 15 m (49 ft) speaker cable provided with the GP12 passive loudspeaker to connect the speakON B connector on rear panel of the GP12A active loudspeaker to the speakON A connector on the rear panel of the GP12 passive loudspeaker. Daisy chain a further GP18 to speakON B.

Cleaning

Use only a soft, dry cloth to clean the housing. Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. Do not use any sprays near the product or allow liquids to spill into any openings.
