Installation and user manual
Description
First One M
power
medium size ready made single channel Class
AB power amplifier module, carefully designed
for DIY or OEM implementations of the most
demanding audio applications, such as stereo
power amplifiers, monoblock power amplifiers
or active multi-way powered speakers.
First One M power
assembled, pre-calibrated and tested in our
production. Measurements and calibrations of
all vital electrical parameters were already
performed in our laboratory, so all that's left to
be done is to mount it to a proper heatsink,
install it into a suitable metal chassis and
connect to a proper DC power supply. Our
recommendation goes to either a switch mode
power supply or classic linear power supply
with minimum of 10 A peak output current per
rail. Properly made wiring connections of the
First One M power amplifier module followed
with short form operating instructions are well
explained in this installation and user manual.
