Important Safety Information
CAUTION!
Service and repair work must only be carried out by quali ed personnel. Do not open the case as
there is a risk of electric shock. There are no controls or components inside the device that require
you to open the case. If the case has to be opened by quali ed personnel, make sure that the device
is completely disconnected from the power supply.
The operating voltage must match the local power supply.
The device should be shielded from moisture and wet conditions. It must not be operated in rain or close
to water, baths, washbasins, sinks, swimming pools or in damp environments. Do not place any objects
 lled with water such as vases, glasses or bottles on the device.
Avoid direct sunlight and do not install it in the direct vicinity of radiators or other heat sources.
Upon sudden change of climatic conditions (e. g. transfer from a cold place to a warm room) water may
condense inside the device, which may lead to malfunction or damage. Before switch-on wait until the
ampli ers have reached room temperature.
Unplug the mains plug to protect the device during a thunderstorm or if it is going to be left unsupervised or
unused for a longer period of time. This prevents the device being damaged by lightning strikes or voltage
surges in the mains grid. Do not touch the case when the device is in use as it may heat up
during operation. Make sure that the device is ventilated suffi ciently.
Improper use will invalidate the warranty!

1. Connecting audio cables
 Connect the line out or the headphone output of the display or other device to the line-in cinch
input on the active speaker’s connecting terminal. (If the display only has one digital audio output,
the signal must  rst be converted.)
 Connect the passive speaker (right) to the four-pole speaker terminal on the connecting terminal.
On model DL-A 2.0, the speaker cable is already attached to the passive speaker. On model
DL-A 2.2, connect the active and passive speakers to the four-pole speaker cable provided
(four-pole connectors on both sides).
2. Connecting the power supply
 Turn the volume control for the active speaker all the way to the left (volume 0).
 Insert the mains adapter provided into the green power supply terminal on the active speaker
and connect to the mains grid using the cold device cable.
3. Starting up the speaker system
 Switch on the display or other device and set the output volume of the audio output to approximately 60-70 percent.
 The speakers feature an automatic switch-on function and automatically activate when an audio signal is detected
at the input. When this happens, the LED in the terminal panel lights up green.
 Turn the volume controller on the connecting terminal up to the desired operating volume.
4. Grounding the speakers (ground lift switch)
 Depending on the grounding used for the display and other connected components (e.g. PC and crossover switches),
the speakers may or may not have to be grounded. The ground lift switch is designed to do this. If the other devices
are grounded, the speakers should not be grounded (ground lift). If the devices are not grounded, the speakers should
be grounded (ground). Incorrect grounding will result in buzzing sounds and interference.
5. Automatic switch-on function
 If the speakers do not receive a signal for more than ten minutes, they automatically switch to standby.
The LED in the terminal panel goes out.

The parts of the DL-VESA mounts can be used dierent, depending on dimensions of display and speaker model (see page 12 – 15)

14
Variante A
For 200 – 400 mm VESA
standard mounts.
Attach the T-shaped
brackets directly to the
L-shaped brackets;
position the T-brackets
symmetrically, with the
baseplates facing outwards.
The L-shaped brackets can
be attached forwards or
backwards depending on
the depth.
Variante B
For 400 – 600 mm VESA
standard mounts.
Attach the T-brackets
directly to the L-brackets;
position the T-brackets
symmetrically, with the
baseplates facing inwards.
4.2. DL-VESA Assembly with DL-A 2.0 / DL 2.0

15
Variante C
For asymmetrical VESA
standard mounts.
Attach the T-brackets
directly to the L-brackets;
use two identical
T-brackets on each side.
The L-brackets can be
mounted on the front or
back of the T-bracket
depending on the depth
of the display.
Variante D
For very deep displays.
Use extension plates
between the T-brackets
and the L-brackets to add
extra space.
4.2. DL-VESA Assembly with DL-A 2.0 / DL 2.0

16
Variante E
For VESA standard mounts
under 200 mm.
Attach the T-brackets
directly to the L-brackets;
position the T-brackets
symmetrically, with the
baseplates facing outwards.
Variante F
For a VESA standard
mounts over 600 mm.
Attach the T-brackets
directly to the L-brackets;
position the T-brackets
symmetrically with the
baseplates facing inwards.
4.2. DL-VESA Assembly with DL-A 2.0 / DL 2.0

17
Extensions
Variante G
For flat displays used with
deep DL-A 2.2 display
speakers, the T-brackets
are mounted facing
forwards to compensate
for the gap.
Variante H
If you need extra length,
use extension plates
between the T-brackets
and the L-brackets.
