Introduction
This section briefly describes the possibilities of the LX523 Active Speaker System with
remote input.
he LX523 is a speaker set consisting of one active and one passive speaker, to be linked
be linked together. What makes the LX523 special and superior to traditional active
active speaker systems is the remote input connection (RJ45) which provides the
the possibility to transfer a signal (both line and microphone level with local mixing) from
mixing) from a wall panel (WP523) or web based input control unit (RM523) to the speaker. The
panel allows both line and microphone level signals to be mixed locally. This way, the speaker set is
ideal for small to medium fixed installations where the loudspeakers become a part of the standard
equipment. This set was specifically designed for interiors such as classrooms, conference rooms,
meeting rooms, … The input and/or control unit can be unobtrusively installed at locations which
are easily accessible for the speaker such as walls, the pulpit, the tables, …
The audio signal will be transferred from the input or control unit to the speaker by using only one
single CAT5 cable which simultaneously provides the power supply to the input unit.
Key features:
-3-Way speaker system
-One Passive and one active speaker
-Two band tone control (Bass & Treble)
-RJ45 Remote input connection
-Adjustable mounting brackets
-Easy to mount on walls/ceilings
-Available in Black (/B) and White (/W)

Ensure that sufficient space is available behind the active speaker for cooling.
Do not open the unit (risk of electrical shock).
Always read the user manual before getting started.
CAUTION – SERVICING
This unit contains no user serviceable parts. Refer all servicing to qualified
service personnel. Do not perform any servicing unless you are qualified to do
so.

Description
1: Speaker output:
This two pin EURO terminal block connector should be used to connect the supplied passive
loudspeaker. Using other loudspeakers can give bad result and even cause damage to the main unit.
Be sure that the polarity of the speakers is correct.
2: On / Off switch:
The main unit can be turned on and off with this power button. When switched on, the green
power LED at the bottom of the amplifier unit should illuminate.
3: Power supply socket:
The unit should be connected to the mains circuit by using a standard IEC type power cord. This
socket contains a 1A slow blow fuse. To replace the fuse, the fuse compartment has to be flipped
out by a screwdriver. Be sure that you don’t use a quick blow fuse. This socket doesn’t contain a
ground pin to avoid ground loops.
4: Heat sink:
When using the LX523 at full power for a long time, this heat sink will warm-up. Make sure there’s
always some space behind the speaker ensuring a proper airflow. Take care when placing the
speaker close to other items sensitive to heat. Don’t touch!
5: Volume Control:
With this button the general volume for the speaker system can be controlled.
6: Treble Control:
With this button, the high frequency’s can be increased and decreased. Adding high frequency’s can
improve the intelligibility. Adjust it to the desired level. In the centre position, the sound should be
neutral.
7: Bass Control:
By adding bass, you can add warmth to your music. Decreasing bass can improve the intelligibility
of spoken messages, certainly in reverberant rooms.
8: RJ45 Remote input
The remote input unit (WP523 wall panel or RM523 web based input control unit) should be
connected to this RJ45 connector by means of CAT5 (or better) twisted pair cabling. For more
information about wiring the input units to the speaker system, read the next chapter of this
manual.

Remote input connection specifications
The connections between the LX523 speaker system and the used input unit (WP523 or RM523)
should be always made by means of twisted pair cabling. The maximum cable distance between the
input unit and the speaker system depends of the used cable. For standard CAT5 cable, the
maximum cable distance between the input unit and the speaker system can reach up to 500 meter.
When better CAT6 or CAT7 cable is used, the maximum cable distance can reach even longer
distances.
To ensure a proper working of the system, all 8 conductors of the twisted pair cable have to be
connected according to the table below.
ATTENTION
The twisted pair cabling must always be ‘straight’. In case of
self made cabling, it must be wired ad described above, to
make the system work properly.

WP523
In the most common applications the LX523 active speaker system will be used in combination
with the WP523 wall panel. This wall panel contains an unbalanced line input (RCA) and balanced
microphone input (with phantom power). Both input channels have local mixing which can be
controlled through the push-lock potentiometers, and the master volume can be controlled by
means of the big dial.

The WP523 wall panel should be connected to the LX523 speaker system by means of the 8-pin
Euro-Terminal block connector on the rear side of the wall panel. The pins starting from Pin 1 on
the left side, to Pin 8 on the right side should be connected with the corresponding conductors of
the twisted pair cable as described on the previous page.

523
When connecting the LX523 speaker system to an RM523 Web based input control unit, both
devices use RJ45 in- and output connectors. In this case, just a regular CAT5 cable (or better)
should be used, on both sides terminated with an RJ45 plug. The connection way of this cable
should be ‘Straight’, according to the colour standard described before in this user manual.
Connecting multiple LX523 sets to one input unit.
The mains for powering the input units (WP523) is distributed from the LX523 speaker over Pin 3
and Pin 4 (White-Green & Blue conductor) of the twisted pair cabling. When connecting multiple
speaker sets to one single input unit, make sure the mains from only one speaker set is distributed
to the input unit. When connecting all pins (& power supply’s) from all loudspeaker sets with each
other, this can cause malfunctioning to the system. To prevent any malfunctioning of the system
the Pin’s 3 and 4 from the other speaker sets should be interrupted
.

Attention
Make sure the mains power for the input units is only distributed from one loudspeaker at a
time. When the power is distributed from multiple loudspeaker sets, this can cause
malfunctioning of the system. This can be avoided by interrupting Pin’s 3 and 4of the
twisted pair cabling for the additional loudspeaker sets.
