Introduction
Remote Wall Mixer for LX523
The WP523 is a Remote Wall Mixer which is meant to be used in combination with the LX523
Active Speaker system. It converts the signal coming from a stereo line-level audio source (such
as CD-player, Tuner, MP3 player, ... ) or balanced microphone to the level corresponding the
differential signal input on the rear side of the LX523 (RJ45).
Making it possible to transfer high-quality audio over long distances between the wall panel and
loudspeaker, by just using inexpensive twisted pair CAT5 cabling.
On the front side of the wall panel is a stereo RCA line input together with a balanced XLR
microphone input. Both provided with their own knob, which allows the signals to be mixed
together. A main volume dial allows you to adjust the overall volume of the loudspeaker system.
An internal limiter avoids distortion on the input signal and a jumper on the rear side allows you to
provide 12V phantom power to the microphone input.
The connection of the CAT5 cable can be made on the rear side of the wall panel by means of an
8-pin Euro-Terminal Block connector.

Overview front panel
The front panel of the WP523 contains an unbalanced line input connected by RCA connectors and
a balanced microphone input connected by a XLR connector. Each input is accomodated with a
push-lock gain control potentiometer whereby both inputs can be mixed and a Clip indicator LED.
The overall volume can be controlled by means of the big rotatable dial.

Front panel description
Unbalanced line input
An unbalanced stereo audio source can be connected to these RCA connectors.
Balanced microphone input
A balanced microphone can be connected to this XLR input connector. For powering condenser
microphones, 12V Phantom power can be enabled.
Push-Lock gain control potentiometer with clipping LED
The sensitivity for the line and microphone inputs can be adjusted with these potentiometers.
Through the push-lock mechanism, they can be opened and hidden again by pressing them.
Above every potentiometer is a clipping indicator LED provided which illuminates when clipping
of the input signal occurs. When this LED is lit, the signal is distorted and the level should be
reduced by turning back the potentiometer. The sensitivity for the line and microphone input can
be adjusted between the ranges of 0dB and -∞dB.
Master Volume Control
By means of this rotatable dial, the overall volume can be controlled. The volume can be
increased by turning the dial to the right, while it can be decreased by turning the dial to the left.

Overview rear panel
The rear side of the WP523 contains an 8-pin Euro-Terminal Block connector, whereby the wall panel
should be connected to the RJ45 connector on the rear side of the speaker system. For more information
about how the connections should be made, refer to “Connecting” in Chapter 3 of this user manual.
Below the 8-pin connector is a jumper located, whereby the 12V phantom power for the microphone input
can be enabled. When the jumper is placed (standard with delivery), the 12V phantom power is enabled,
and can be disabled by removing the jumper.

Quick start guide
This chapter guides you through the setup process for a basic setup where a WP523 should be
connected to a LX523 loudspeaker system.
Install your WP523 wall panel on the desired location by means of the optional available WB5065
installation boxes. Provide a twisted pair cable from the loudspeaker to the WP523 wall panel.
Connect the twisted pair cable according to the standards described in this user manual with the RJ45
connector on the loudspeaker side and to the 8-pin Euro-Terminal block connector on the wall panel
side. After all those connections are made, just plug-in the connectors of the twisted pair cable, plug
in the mains power on the loudspeaker side and your system is ready for operation.
You can plug in your line and microphone audio sources to the wall-panel, and your sounds should be
audible through the speaker system. The master volume and mixing can be done with the push-lock
and the big rotatable dial on the wall panel. Make sure that the settings for volume and tone control
on the rear side of the speaker system are correct too.

Installing & Connecting
Installing
For installing the WP523, two different kinds of flush mount installation boxes are available.
The plastic installation box (WB5065/FG) is meant to be used for installation into gypsum, wooden
or other kinds of plate walls with a thickness between 7 mm and 25 mm. An installation hole with
dimensions 135 x 75 mm should be cut wherein the installation box should be placed. When the wall
panel is placed into the installation box and the screws are tightened, the wall panel will be secured to
the wall.
The second type of installation box is a steel version (WB5065/FS) which can be used for mortar in
brick or stone walls. Make sure the installation box is installed upright (notice the text and the sticker
on the installation box)

Connecting
The WP523 wall panel should be connected to the LX523 speaker system by means of UTP twisted
pair cable. The 8-pin Euro-Terminal Block on the rear side of the WP523 should be connected to the
RJ45 connector on the rear side of the speaker system. The maximum cable distance between the
input unit and the speaker system can reach up to 500 meter.
To ensure a proper working of the system, all 8 conductors of the twisted pair cable have to be con-
nected according to the table below.
PI Port PINOUT (Audio, +/-12V DC):
Pin 1 White-Orange AUDIO LEFT
Pin 2 Orange AUDIO LEFT
Pin 3 White-Green +12V DC
Pin 4 Blue -12V DC
Pin 5 White-Blue GND
Pin 6 Green GND
Pin 7 White-Brown AUDIO RIGHT
Pin 8 Brown AUDIO RIGHT

ATTENTION
The twisted pair cabling must always be ‘straight’. In case of self
made cabling, it must be wired as described in this chapter to make
the system work properly.
The twisted pair cable should be connected to the 8-pin Euro-Terminal Block connector on the
rear side of the wall panel. The connector starts with Pin1 on the left side to Pin8 on the right side.
These Pin’s should be connected to the corresponding Pin’s of the RJ45 connector.
