The PA202 is a very compact 20 X 20 Watt high efficiency Amp with barrier strip terminals for the Balanced input and speaker outputs. The unit is perfect for small speakers in small environments. Great for in ceiling and projector applications where small size is needed along with class D low heat emitted from chassis.
Bridge or Stereo Operation:
The bridge - Stereo function of the PA202 is a way of converting the unit from two channels at 20 Watts each to one channel at 40 Watts. To do this, depress the CONFIGURATION SWITCH and follow the silk screening on the chassis for the mono-bridge operation.
The Limiter is a function that will not allow very loud signals to pass through the PA202 by limiting their volume temporarily to a normal level, preventing damage to the speakers or the unit its self. It is important to note that the Limiter utilizes a circuit that decreases the amount of very loud signals it does not cut out all potentially loud signals. Proper installation and setup is crucial. If you are experiencing distortion turning the Limiter on may help somewhat but it is not designed to control distortion. Its primary function is to help prevent one time very loud signals like dropping a Microphone or loud program material that is temporary.
