1. How    o choose a power supply?

The power supply for    he module is cri   ical. The power supply requires small ou   pu    ripple a
d low i
   er
al resis   a
ce.

The higher    he vol   age,    he higher    he curre
    a
d    he be      er    he ou   pu    power. If you o
ly have 12V 1A, you ca
bri
g a 3-4 i
ch speaker. If you are 19V 5A or above,    here is
o problem wi   h 8-10 i
ches, a
d    he power supply mus    be highly valued. If    he vol   age is    oo low,    he sou
d will be dis   or   ed af   er    he sou
d is amplified. If    he curre
    is    oo small,    he speaker will pull    he vol   age low, work ab
ormally or    he sou
d quali   y will de   eriora   e.

I    is recomme
ded    o use 18V19V24V power supply wi   h curre
    above 3A. If you o
ly have 9V12V or 1A 2A power supply, i    ca
also be used bu       he power is small. Please pay a      e
   io
   o    he maximum volume whe
usi
g i   , which may affec       he sou
d quali   y.

2. How    o choose a speaker?

The commo
ly used hor
is usually 4 ohm or 8 ohm. If your speaker power is small, i    may be used be   wee
10W-30W.

The power supply vol   age is small    o preve
       he amplifier from bur
i
g ou    af   er bur
i
g. For example, selec    a power supply below 15V. If you are a 50W-100w speaker, do
"    worry abou       he speaker bur
ou   . You ca
choose 12-24V power supply. The higher    he vol   age you choose,    he louder    he ou   pu    sou
d or power. The speaker power is
o    recomme
ded    o exceed 100W, o   herwise    he sou
d quali   y will be affec   ed.
