Install the power amplifier
Prior to fastening the amplifier into the chassis:
1.
Connect the yellow RLYDRV wire from the power supply to the RLYDRV eyelet
on the right side of the power amplifier PCB. Insert it from the solder side, and
solder it on the component side.
2.
Connect the following wires to the amplifier module. Insert from the solder side
and solder on the component side. You may shorten the wires before installation,
but leave them long enough that you access the bottom of the PCB for later
assembly or troubleshooting steps.
a.
INGND wire from C11 to the INGND terminal.
b.
RIGHTIN wire to the RIGHTIN terminal.
c.
LEFTIN wire to the LEFTIN terminal.
3.
Connect the LEFTOUT wire to a length that comfortably reaches the LEFTOUT
eyelet of the amplifier PCB to allow easy access for service. Insert the wire from
the solder side and solder on the component side
4.
Connect the RIGHTOUT wire to a length that comfortably reaches the
RIGHTOUT eyelet of the amplifier PCB to allos easy access for service. Insert
the wire from the solder side and solder on the component side
5.
Solder the following wires from the bonded pairs to C7L and C7R:
a.
Connect the Green wire from the C7LNEG eyelet on the board to the
negative terminal of C7L. C7L is near the transformer.
b.
Connect the Yellow wire from the C7LPOS eyelet on the board to the
positive (RED) terminal of C7L. C7L is near the transformer
