13: What are the true RMS wattage specifications for this
device, when the power is 2Ω, 4Ω?
• 220 watts are the MAX power output. Its RMS power output is
RMS 150watts @ 4Ω, RMS 120watts @ 8Ω with 24V 4.5A
power supply. If you want to get more power, you can upgrade the
power supply with 24V 8A.
14: Why cuts the sound in or out?
• Try to reduce the sound of your device.
• Ensure that the positive and negative poles of the speaker output
do not touch each other. Some relatively large banana plugs are
easy to touch each other and will cause a short circuit.
• Try to exchange your audio source to test, if still so then there
are problems with the amplifier.
15: Low Volume.
• Recheck the volume on your device and turn up the sound of the
amplifier. Make sure that it isn't set to minimum volume.
• Please make sure if your device needs a pre-amp or not.
• If you are using the turntable, please make sure if your turntable
needs a phono preamp or not. Some turntables have built-in
phono preamp, some not.
16: Can I use the TP-02 in other countries?
• Yes, the wide voltage AC 110-240V for power input can be used
in any country. You need only to match the power cord adapter
with the power supply in that country.
