at the leftmost end, avoid high volume ( high output power )
damaging your speakers.

speakers, speaker cables, interference sources, poor contacts
and the device itself. How to determine the reason: 1) remove
all input cables and make sure no interference sources around
such as routers; 2) connect the amp to speakers; 3) connect the
amp to power supply correctly and turn on the amp; 4) if noise

or speaker cables. Please use another speaker, speaker cables
or power supply to check one by one for further determination; 5)
if no noise, please use other audio cables or audio sources for
further determination.
