Foreword
The G3 dp with integrated 2x1500 Watt digital amplifier electronics and DSP
controller houses six 8” low-mid drivers and three 1.4” hf-drivers, using the
same technology as the Galeo line array. Unlike the Galeo, each G3 has a
fixed vertical dispersion of 20°. Due to the high acoustical output from 80Hz on,
it can be combined with the G-Sub or 2x 18” or even 2x 21” subwoofers.
The tilt and pivot frame included as standard facilitates simple alignment of the
system. Both, ground stacked and flown applications are possible.
High-grade electronic components from the industrial sector and a first-class
circuit design ensure excellent audio quality with low distortion and effectively
minimise static noise. Highly efficient and “intelligent” limiter systems ensure
optimum protection against overload, without restricting the possibilities offered
by this high-performance sound system.

Safety instructions
-acoustic
Even with a low power input the G3 dp unit can produce a hazardous sound
pressure level that may cause acute and permanent damage to the ear. Never
sit or stand in the immediate vicinity of the loudspeaker during operation and
always wear ear protection.
Observe the respective German trade association regulation BGV B3
pertaining to noise
- mechanical
During assembly and disassembly, moveable devices and falling parts may
cause serious physical injury.
Observe the respective German trade association regulation BGV D8
pertaining to winches and hoisting gear (basic principles of prevention) as well
as those regarding event and production facilities for the performing arts.
- magnetic and electrical
Even if not connected to a power source, loudspeakers produce a static
magnetic field that can damage cards with a magnetic strip or delete sound
recordings and the like. During operation this voltage is also present on the
PowerCon Loop Thru input. Observe the respective German trade association
regulation BGV A2 pertaining to electrical equipment and utilities.
Assembly and disassembly must be carried out only by qualified personnel who
are familiar with the corresponding regulations and adhere to and act in
accordance with them. Please note that all quoted regulations are
predominantly applicable in Germany. Work in compliance with the regulations
applicable in the country you are in.

Do not operate the G3 dp if you have any concerns regarding safety or if the
loudspeaker box should malfunction. The equipment has no user-serviceable
parts inside. In the event of repair, please contact your dealer or qualified
personnel respectively.
Connect the G3 dp to a 115-230V/50-60Hz grounded safety socket. The
equipment corresponds to protection class 1. In case of overload, a protective
element is activated which reliably protects the amplifier module and the DSP.
However, it must then be replaced by an authorised service centre.
Always remove the mains plug when opening the loudspeaker box (for
example when turning the horn).
Do not expose the G3 dp to rain and, if possible, do not operate the speaker
outside of a temperature range of -5°C to 40°C. Bear in mind that strong
thermal fluctuations result in the formation of condensate, therefore do not
operate the speaker until the speaker box has assumed the ambient
temperature. Do not switch the equipment off if it is being used in adverse
conditions.
In order to avoid overheating of the speaker chassis and the built-in amplifier
module, never operate the G3 dp in the close vicinity of intense heat sources
and avoid direct sunlight.
After several hours of operation the housing (especially all-metal parts such as
the M20 flange and connection panel) can reach temperatures of up to 40°C.

Part 1 – Connections and indicator functions
Connectors
•XLR In: The G3 dp is controlled via a conventional symmetrical NF
cable. For signal loop-through use the male Loop Thru XLR In. For full
conduction the connected signal source should deliver at least 6 dBU
undistorted.
•PowerCon (grey) 115-230 VAC Loop Thru input. This is required if
power is to be supplied to several active speaker boxes and only a
115-230 Volt AC lead is being used. Please observe the maximum
permitted connected load. In practice, power can be supplied to up to
two additional systems.
•PowerCon (blue): Power supply 115-250 VAC. This plug has the
same function as an on-off switch. Ensure that a 115-230 VAC mains
voltage is available. After switching on (clockwise rotation until it snaps
into place), the system starts up and is ready for use within 3 seconds.
Avoid continuous switching on and off, particularly when the system is
under sustained load.

Control Elements
•MODE button: changing to control modes Status / Level and Presets.
• SET button: Setting of various values and Mute on/off
Status indicators
•Mute LED: red light when the system is muted (press Set button in
Status mode) or under technically crucial conditions.
•Limit LED: yellow light when the limiter is restricting the level of at
least one amplifier channel.
•Signal LED: green light if a signal exceeds –20 dBU. This also applies
when the mute function has been activated:
•Power LED: lights up when the system is switched on.

Part 2 – Operation
System start-up
The previously selected setting is maintained when the equipment is switched
on. The system is then in Status mode. If the red Mute LED lights up according
to the previous setting, there is no signal being transmitted. If the Set button is
pressed once, the mute function is deactivated, the Mute LED goes off and the
system transmits a signal.
Adjusting sound levels
By pressing the Mode button once you will gain access to the Level mode,
permitting adjustment of the volume in 3dB stages. Four different values +3dB,
0 dB (standard), -3dB and –6 dB are available. Adjustment is effect via the SET
button. The green LED located above it indicates which mode you are currently
using, whereby the four vertically arranged LEDs (now green) indicate each
value set.

Accessing presets
By pressing the MODE button twice you will gain access to the Preset mode.
Three different presets and an additional Soft mode can be selected via the
SET button:
•Flat : This setting facilitates a linear frequency response from 80Hz up.
Frequencies below 80Hz are not raised electronically, therefore the use of a
subwoofer is obligatory for music transmission.
•-Low (soft): The low-mids are reduced for better speech intelligibility.
Reduces the low-mid summation taking place when several G3 dp are
operated in a line.
•-Low (hard): The low-mids are reduced even mor for better speech
intelligibility. Stronger reduction of the low-mid summation taking place when
several G3 dp are operated in a line.
•Soft Mode: Lowers the level within the frequency range of 2.5 – 5 kHz
which is sensitive to the ear. This setting is recommended for high level
reproduction of highly compressed music tracks. This function operates
independently from the choice of the three possible presets.
Lock function: If the SET and MODE buttons are simultaneously pressed for
more than three seconds, the operational function is disabled. Press the
buttons again in the same way to release the lock.
