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 LX503 MKII 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: Stereo / Mono switch:
The operation mode can be switched between Mono and Stereo mode by means of this switch.
When the speaker is used in Mono mode, the input signal applied to the Left input signal will be
fed to the amplifier.
9: Unbalanced Line input RCA
The sound source such as CD-player, DVD player, Tuner, … can be connected to this unbalanced
line input. The applied signal should be a line-level signal. A microphone mixer of preamplifier is
required for connecting a microphone.
10: Unbalanced Line input 3.5 mm
This Line level stereo input is useful when connecting a computer or a portable source (CD, MD,
mp3, …).
11: Balanced Line input
These inputs can be used when connecting source devices with a balanced output signal. The
balanced input connections are performed using three-pin Euro-Terminal block connectors.
Balanced signals are less sensitive for interference caused by external devices. For this reason is
balanced wiring recommended when using long cable runs between the source device and the
speakers, or when installed in areas where a lot of interference occurs.
