1 Power Handling
Power rating with regards to loudspeakers denotes how much
power the loudspeaker can handling for a sustained period of
time without distortion. These speakers are rated to accept up
to 50 watts RMS.
2 Watts
The most consistent standards for measuring watts are
"Program Power" and "RMS" because these measure average
sustained levels. Any low impedance amplifiers with an output
of 2 x 10w - 2 x 50w (@ 8 ohms) are suitable for use with these
speakers.
NOTE: The power output from an amplifier depends on the
number of loudspeakers attached.
8 ohms normally denotes two loudspeakers attached
4 ohms normally denotes four loudspeakers attached

4 Troubleshooting

If your system is not operating properly, please refer to the
following information. If the problem persists, disconnect from
power and contact your AV reseller immediately.
Problem Correction
Sound only coming • Turn off amplifier and switch
out one side output connections. If the side
changes the amplifier is okay
and the fault is with one of the
loudspeakers.
• Switch input connections and
check input cabling.
Sound very quiet • Have you used unshielded
speaker cables? Use cable
with gauge of 0.75mm or
higher. Note: Phono or minijack
cable is shielded and is not
appropriate.
