Overview
The Lepai LP-2020A+ uses the Class-T Tripath TA2020
Audio Amplifier IC for low distortion, acoustically accurate
reproduction of music. Ideal for both home and car audio
applications.
Tone/Direct switching allows for customized listening
via separate Bass and Treble adjustments or original
audio source signal can be passed through without
enhancement.
Built-in loudspeaker protection circuit triggers when
the amplifier is turned on to protect speakers from high
volume bursts of audio.
Over-voltage protection circuit shuts down amplifier
should input voltage exceed 14.4 Volts DC.
State of the art design using surface mount components
and advanced engineering for proven performance,
reduced signal interference, and long operational life.

Questions and answers
only one speaker is working. Tested speakers, cables and conections. Can't figure it out.
The provided context does not directly address a situation where only one speaker is working with the Lepai LP-2020A+ amplifier. However, potential causes based on general knowledge of the amplifier could include:
1. Faulty Connection – Check if the speaker wires are securely connected to both the amplifier and the speaker.
2. Defective Speaker – Test the speaker by connecting it to the other channel.
3. Amplifier Issue – The amplifier may have internal faults, such as a problem with the volume potentiometer or gain stage, which could affect one channel.
4. Source Problem – Ensure the audio source is outputting a stereo signal and that both channels are functioning.
5. Balance Settings – Some audio sources or systems allow balance adjustment, which might be set incorrectly.
If the issue persists after checking these factors, the amplifier may be defective.
