Most all external amps use up voltage power supplies. The HU is limited to
12-15 volts with a bridge amp inside. The amp is like a 1.25 inch plate
which is mounted to a small heat sink. There can be a stereo chip, and
that would require using two for 4 channels. 15 watts is a good figure. This
used to be called high power. Regular power was using a single amplifier
without bridging. Figure about 4 watts max. This is how it used to be
for solid state HU's without "high power". Before that tubes and transformers
could negotiate volts and watts better. Getting drive from a high level stage
invoves more distortion, but not necessarily objectionable.
