FOR EQUIPMENT THAT CONNECTS TO THE POWER MAINS -
CAUTION: If the power cord of the device is equipped with earthing contact, then it must be connected to an outlet with a protective ground. Never deactivate the protective ground of a power cord.
-
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.
-
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 the power adapter does not fit in your wall outlet, contact your electrician.
-
Do not step on the power cord. Make certain that the power cable does not become kinked, especially at the main outlet and/or power adapter and the equipment connector.
-
When connecting the equipment, make certain that the power cord or power adapter is always freely accessible. Always disconnect the equipment from the power supply if the equipment is not in use or if you want 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.
-
Whenever possible, avoid switching the equipment on and off in quick succession because otherwise, this can shorten the useful life of the equipment.
-
IMPORTANT INFORMATION: Replace fuses only with fuses of the same type and rating. If a fuse blows repeatedly, please contact an authorized service center.
-
To disconnect the equipment from the power mains completely, unplug the power cord or power adapter from the power outlet.
-
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.
-
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.
-
The appliance is not to be used by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge.

CONNECTIONS, CONTROL, AND DISPLAY ELEMENTS
POWER SOCKET AND FUSE HOLDER
IEC power socket with integrated fuse holder. A suitable power cable is
included in the delivery.
IMPORTANT NOTE: Only replace the fuse with a fuse of the same type and
values. Please note the inscription on the housing. If a fuse trips
repeatedly, please contact an authorized service center.
POWER
On/off switch. The speaker should always be the last device to be switched on
in the signal chain and the first to be switched off.
LC DISPLAY
Multifunctional graphic LC display for displaying the master volume, the DSP
preset and the input level for channels 1 and 2 in the main menu. The menu
items, submenu items, and corresponding editing options are displayed in the
Editing menu.
VOLUME / PUSH FOR MENU
From the main menu, the master volume can be adjusted by turning the rotary-
push encoder. Press the rotary-push encoder to access the Editing menu. Use
the rotary-push encoder to navigate the Editing menu, adjust system settings,
and change values in the respective menu items.
INPUT 1–2
Balanced channel 1 and 2 line inputs with XLR/jack combo sockets A connected
stereo signal is summed to mono internally.
THRU 1–2
Balanced line outputs with male 3-pin XLR sockets for forwarding the line
input signal.
CASTOR ASSEMBLY
The back of the subwoofer is set up to attach four optionally available
transport castors, each equipped with four ex-works fastening screws and
recessed. The hole spacing is standardized. A large selection of castors can
be found at adamhall.com
OPERATION
NOTE:
The LD Systems logo briefly appears on the display as soon as the speaker is
correctly connected to the power supply and switched on. All settings (e.g.,
Preset and Delay) resume the way they were as before the speaker was switched
off. The speaker will be ready for use after the completion of this process,
which usually takes one second.
MAIN MENU DISPLAY
The main display is activated during normal operation. It shows the master
volume setting, the activated speaker preset, and the input levels of channels
1 and 2 with peak display (see figure). Reduce the source device’s output
level (e.g., mixer) if the peak display shows that the input signal is too
high.
VOLUME
From the main menu, the volume can be directly adjusted by turning the rotary-
push encoder VOLUME / PUSH FOR MENU from -60 to +10 dB. When the encoder is
rotated, the display automatically changes to the corresponding symbol (see
figure below). The main menu will automatically reappear after approx. 20
seconds of inactivity. Pressing the encoder immediately changes the display to
the main menu.
AUDIO SETTINGS (AUDIO)
Press the rotary-push encoder to access the main menu and then turn the
encoder to select the menu item AUDIO (dark background). Press the encoder
again to access the submenu and then turn the encoder to select the desired
submenu item. Confirm the selection by pressing the encoder.
Refer to the table below for the submenu items and the relevant setting options.

Hz in the main subwoofer. The delay time, polarity, and volume for the two
subwoofers must all have the same setting.
DELAY| Time delay of the audio signal in 0.32 ft steps up to 32 ft (0 ft
= OFF, display in meters and feet)
POLARITY| Sets the polarity| NORMAL| Normal polarity
INVERTED| Inverted polarity

CARDIOID SET-UP
The loudspeaker CARDIOID preset is complex DSP programming that enables a kidney-shaped radiation pattern (cardioid sound radiation) to be achieved by a combination of two LD ICOA subwoofers of the same model. In comparison to conventional subwoofer setups, it provides the following advantages:
- Reverse attenuation up to 20 dB
- More precise bass reproduction in the listening area
- Prevention of unwanted reflections from rear walls
- Reduction of diffuse sound in rooms
- Elimination of annoying bass frequencies on the stage
- Differentiated sound pattern for stage sound reinforcement (monitoring)
- Reduction of feedback occurring with stage microphones
As illustrated, place two subwoofers beside each other, with the subwoofer
with the cardioid preset facing backward (see figure below). Select the 100 Hz
preset for the front-facing main subwoofer and ensure that the delay time,
polarity, and volume settings for both subwoofers are the same.
WHAT DO LD SYSTEMS DYNX® DSP MEAN?
DSP is an acronym that stands for digital signal processing. DynX® includes
the Limiter, EQ, Compressor, and Low-Pass Filter. Digital signal processing
ensures optimal audio bass reproduction with maximum clarity while protecting
the subwoofer from overloading.
WHAT EXACTLY DOES DYNX® DSP DO?
The Limiter function protects the speaker and prevents overload-induced
distortion. The subwoofer allows the system to be operated at an overall
higher sound pressure since extreme signal peaks are automatically limited so
that the master volume does not have to be reduced. The multi-band EQ handles
the entire bass range and optimizes the subwoofer’s overall sound.
