Troubleshooting/Qa - Fosi Audio TP-02 User Manual

Troubleshooting/QA

1: The power supply indicator is not illuminated.
• Make sure that the AC power cord is securely connected to the
power supply and to an AC power outlet.
• Check whether the power LED on the power supply stays on. If
not, the power supply is broken.
• If you make sure the power supply is defective, please contact us
for exchange.
2: Which type of speakers works best with the TP-02
Amplifier?
• Fosi Audio TP-02 works well with most 2-8Ω subwoofers.
3: Why does the TP-02 make serious noise when used
together with a radio?
• The common feature of Class D power amplifiers is that they can
cause serious noise when used with a radio, so we do not
recommend using the TP-02 with a radio or too close to it.
4: Why there is no voice from my amplifier?
• Please make sure that the AC outlet is on and working.
• Verify that the amplifier and your devices are turned on.
• Recheck speaker wire connections from the amplifier to the
speaker.
• Please make sure that the cable from the power supply is
connected to the amplifier and check whether the power LED on
the power supply stays on. If not, the power supply is broken.
• Please make sure that the volume/power knob on the front panel
is turned on and not set to the minimum volume.
