Don’t tilt or bend the column speaker.
GP18A / GP18
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).
Connector | Terminals | Transducer |
---|---|---|
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.
Stereo quad system
Assemble one GP18A active loudspeaker system with three GP18 passive
loudspeaker systems in stereo mode.
Left channel: GP18A + GP18 Once properly assembled, use the 15m (49ft) speaker cable provided with the GP18 passive loudspeaker to connect the speakON A connector in the GP18A active loudspeaker rear panel to the speakON A connector on the GP18 passive loudspeaker rear panel.
Right channel: GP18 + GP18 Once properly assembled, use the 15m (49ft) speaker
cable provided with the GP18 passive loudspeaker to connect the speakON B
connector in the GP18A active loudspeaker rear panel to the speakON A
connector on the GP18 passive loudspeaker rear panel.
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.
