NOTICE
1. Before turning on the amp, please make sure the volume knob
at the leftmost end, avoid high volume ( high output power )
damaging your speakers.
2. Default OPTIONAL 19V power supply enough to drive most
home speakers. If you buy the version without power supply or
want higher output, please prepare high-quality power supply
by yourself. Powered by 24V power supply(4Ω load), the actual
output power can reach 100W per channel.
3. Noise may be caused by poor audio cables, sound sources,
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 exists, then problem may be the amp, power supply,
speakers 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.
