AC POWER ON
For installations where the S-150m is not accessible or the 12V trig-
ger feature cannot be used, the S-150m may be set to power on
and off with the application or removal of AC power. This mode
bypasses the stand-by mode. The S-150m will go from power off to
full power when the AC outlet is energized. Conversely, the S-150m
will power off when power is removed rom the connected outlet.
Follow these steps to set the S-150m for AC power turn on:
1.
Unplug the S-150m from the AC power outlet.
2.
Use a T-15 Torx driver to remove the top cover screws (14)
3.
On the left side of the amplifier, behind the faceplate, move the
jumper labeled POWER from the two pins labeled MANUAL to
the pins labeled AC. See Figure 1

blue).
Follow these steps to disable the S-150m power indicator:
1.
