SAFETY INFORMATION
◆Read all documentation before operating your equipment. Retain all
documentation for future reference.
◆Save the carton and packing material even if the equipment has arrived in good
condition.
◆Do not spill water or other liquids into the unit.
◆Make sure power outlets conform to the power requirements listed on the back
of the unit.
◆Do not use the unit if the electrical power cord is frayed or broken.
◆Always operate the unit with the AC ground wire connected to the electrical
system ground.
◆Have gain controls on amplifiers or consoles to any other voltage source, such
as a battery, mains source, or power supply, regardless of whether the
amplifier or console is turn on or off.
◆Power down & disconnect units from mains voltage before making
connections.
◆Do not use the unit near stoves, heat registers, radiators, or other heat
producing devices.
◆Do not block fan intake or exhaust ports. Do not operate equipment on a
surface or in an environment which may distort the normal flow of air around
the unit. If the unit is used in an extremely dusty or smoky environment, the
unit should be periodically “blown free” of dust.
◆Do not remove the cover. Removing the cover will expose you to potentially
dangerous voltages.
◆Do not drive the inputs with a signal level greater than required to drive
equipment to full output.
◆Do not run the output of any amplifier back into another input.
◆Do not ground the red output terminal, never connect a red output terminal to
another red output terminal.
◆In case of mal-function this device should be serviced by qualified service
personnel only.

The SF6A Powered loudspeaker set is a very compact, easy to use, plug and play,
music distribution system. It consists of one amplified loudspeaker with a 6 " woofer
and a quality high frequency speaker and a second linkable passive loudspeaker.
1. VOLUME CONTROL
With this button you can easily set the desired volume.
2. TREBLE CONTROL
Herewith you can add or decrease the high frequency. Adding high frequency can
improve the intelligibility. Adjust it to the desired level. In the center position the
sound should be neutral.
3. BASS CONTROL
By adding bass you can add warmth to your music. Decreasing bass can improve the
intelligibility of spoken messages.
4. ON/OFF
When the AC plug is connected to the mains circuit, you can turn the unit on or off
with this button. When the unit is switched ON, the green led should illuminate.
5. INPUT
Here you can connect your sound source. These inputs have to be fed with a music
signal at LINE LEVEL(cd, dve, vhs, tuner, mixing table ……). Connecting a
microphone will give bad result. In this case, you should use a microphone mixer or
preamplifier.
6. SPEAKER OUTPUT
These lockable plugs should be used to free the shipped passive loudspeaker.
Using other loudspeakers can give bad result and even cause damage to
the main unit. The best sonic result will be obtained when the black
socket of the main unit is connected to the black one of the passive
loudspeaker and the red to the red.
7. MAINS SOCKET
The unit can be branched to the mains circuit by a standard IEC type power cord. This
socket contains a 1A slow blow fuse. Use a screw driver to flip out the fuse
compartment and to replace it. When this fuse blows frequently you should bring the
NC to a qualified service center. First check whether you didn’t use a quick-blow fuse!
