4. Protection
The PSA1s has several internal protection mechanisms against over-current, over-excursion,
clipping, and excessive average power output. In some cases, when protection is activated, the
output will be cut off. In these cases, the power LED will blink, and the PSA1s will attempt to restart
itself. If the fault persists, you should take your PSA1s to the nearest authorized service center for
repair by a qualified service technician.
2
At high power levels when the limiter is operating, increasing the subwoofer level control will not
increase the output. For the best results, set the system so that the limiter LED occasionally (a few
times per second) lights up. The limiter is present in the circuit at all times to prevent distortion and
to prevent over-excursion of the speakers.
Note: The PSA1s' built-in stand mounting adapter can be used with the Yorkville SW-TUBEHD
accessory to support either one or two of our PSA1 cabinets. The support tube can be used safely
as long as the PSA1s is on a flat, level surface.
WARNING: Larger or heavier cabinets should NOT be used!
