FOR EQUIPMENT THAT CONNECTS TO THE POWER MAINS:
22. CAUTION: If the power cord of the device is equipped with an earthing contact, then it must be connected to
an outlet with a protective ground. Never deactivate the protective ground of a power cord.
23. If the equipment has been exposed to strong fluctuations in temperature (for example, after transport), do
not switch it on immediately. Moisture and condensation could damage the equipment. Do not switch on the
equipment until it has reached room temperature.
24. Before connecting the equipment to the power outlet, first verify that the mains voltage and frequency match
the values specified on the equipment. If the equipment has a voltage selection switch, connect the equipment to
the power outlet only if the equipment values and the mains power values match. If the included power cord or
power adapter does not fit in your wall outlet, contact your electrician.

To prevent possible hearing damage, avoid listening at high volume levels over long periods of time.
Even exposure to short bursts of loud noise can result in hearing loss. Please keep the volume
constantly at a comfortable level.
SAFETY:
to clean the equipment. Always unplug the power cord and power adapter from the power outlet at the plug or
adapter and not by pulling on the cord. Never touch the power cord and power adapter with wet hands.
27. Whenever possible, avoid switching the equipment on and off in quick succession because otherwise this
can shorten the useful life of the equipment.
28. IMPORTANT INFORMATION: Replace fuses only with fuses of the same type and rating. If a fuse blows repea-
tedly, please contact an authorised service centre.
29. To disconnect the equipment from the power mains completely, unplug the power cord or power adapter
from the power outlet.
30. If your device is equipped with a Volex power connector, the mating Volex equipment connector must be
unlocked before it can be removed. However, this also means that the equipment can slide and fall down if
the power cable is pulled, which can lead to personal injuries and/or other damage. For this reason, always be
careful when laying cables.
31. Unplug the power cord and power adapter from the power outlet if there is a risk of a lightning strike or
before extended periods of disuse.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION:
Never remove the cover, because otherwise there may be a risk of electric shock. There are no user serviceable
parts inside. Have repairs carried out only by qualified service personnel.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user
to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electrical shock.
The exclamation mark within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance instructions.
CAUTION – HIGH VOLUME LEVELS WITH AUDIO PRODUCTS!
This equipment is intended for professional use. Therefore, commercial use of this equipment is subject to the
respectively applicable national accident prevention rules and regulations. As a manufacturer, Adam Hall is
obligated to notify you formally about the existence of potential health risks.
Hearing damage due to high volume and prolonged exposure: When in use, this product is capable of producing
high sound-pressure levels (SPL) that can lead to irreversible hearing damage in performers, employees, and
audience members. For this reason, avoid prolonged exposure to volumes in excess of 90 dB.

CONNECTIONS, CONTROLS, AND INDICATORS:
1LINE INPUT LEFT / RIGHT
Unbalanced line input (left / right) with 2 RCA jacks.
2LINE INPUT LEFT / RIGHT
Balanced line input with 2 XLR / 6.3 mm jack (combo jack).
3LINE OUTPUT LEFT / RIGHT
Balanced line output with 2 male XLR connectors. The output signal corresponds to the input signal.
4SUB PHASE 0° / 180°
The phase reverse switch for the subwoofer (0°, 180°) is factory set to 0°. This setting is suitable for the
majority of applications. In unfavourable acoustic conditions, the setting of 180° may have a positive effect
on the overall sound.
5INDICATOR LEDS
ON: Lights up once the system is properly connected to the power mains and switched on.
SIGNAL: Lights up as soon as an audio signal is present.
LIMIT: Lights up if the loudspeaker system is operating in the clipping range. A short flash of the LED is not
critical. To protect the system, an excessive signal level is gently turned down by the built-in limiter. If the
limiter LED lights up permanently or for longer periods, reduce the volume level. Failure to do so may result
in a distorted sound and damage to the speaker system.
PROTECT: Lights up if the system is overloaded/overheated. The amplifiers are muted automatically. Upon
reaching normal operating conditions, the device reverts to normal operating mode, after a few minutes.

CONNECTING THE SATELLITE SPEAKERS:
The satellite speakers of the LD DAVE18G3 system each have a Speakon compatible speaker connection. Establish
the connection between the subwoofer (SAT POWER OUT LEFT / RIGHT) and the satellites using a suitable cable
(2-wire speaker cable, min. 2 x 1.5 mm², with Speakon compatible connectors.) Allocation: 1+ / 1-).

SPEAKER FLANGE WITH VARIABLE TILT ANGLE:
The satellites of the LD DAVE18G3 system are equipped with the patented SM707 speaker flange with variable
tilt angle (0°, +/- 4.5°, +/- 9°, +/- 13.5°). To change the tilt angle, please follow these steps: Mount the speaker
on a suitable speaker stand, as usual. Now lift the speaker carefully (by approximately 0.5 cm), in order to unlock
the locking mechanism. Tilt the speakers to the desired position and lower it again.
The different tilt angles allow for an optimal positioning of the loudspeakers for different sound situations.
At events with a standing audience and
places where a greater range is required,
it is advisable to use the 0° angle of the
speaker flange.
At events with a seated audience and
rooms with smaller dimensions, it is
advisable to select a downward angle. This
way, in addition to a short-range acoustic
cover, adverse reflections on low ceilings
and rear walls are minimised.
To obtain an optimal dispersion in a pedestal
sound situation, choose an upward angle.

LD SYSTEMS LECC DSP:
WHAT DOES LD SYSTEMS LECC DSP STAND FOR?
DSP stands for Digital Signal Processing (Digital Signal Processing), LECC for limiter, EQ, Compressor and
Crossover. The digital signal processing ensures maximum audio performance with maximum clarity and
protects the PA system from overload.
WHAT EXACTLY DOES THE LECC DSP DO?
The Limiter function protects the speakers and prevents distortions caused by overload. Separate limiters
for the bass, midrange and high range attenuate the signal when the level exceeds a value which could have a
negative effect. Each limiter is optimised for one of the three seamlessly contiguous frequency ranges (multi-band
limiter). The system can be operated in this manner with a higher overall sound pressure as extreme peaks are
automatically lowered, so that the total volume does not need to be reduced.
The Multiband EQ works over the entire frequency range and optimises the overall sound of the system.
The Compressor is switched on automatically to raise the bass response and create a punchier sound. When
the volume is increased, the bass boost is automatically reduced. The automatically controlled bass blends
perfectly into the overall sound.
The Crossovers divide the audio signal according to the frequency range of the respective speakers, namely
the subwoofer or the mids and tweeters of the array column. The amplitude and running-time optimisation of the
crossover ensures that all frequencies are output evenly and reach the listener at the same time.
