• RCA Inputs

• Small compact size

• Class D high e󰀩ciency amp

The PA202 is a very compact 20 + 20 watt high e󰀩ciency amp

with barrier strip terminals for the balanced input and speaker out-

puts. 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 radiated heat locations.

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 screen-

ing on the chassis for the mono-bridge operation.

Bridge or Stereo Operation:

WARNING: THE MINIMUM SPEAKER IMPEDANCE FOR

STEREO (2 CHANNEL OPERATION) IS 4 OHMS EACH.

WARNING: THE MINIMUM SPEAKER IMPEDANCE FOR

MONO/BRIDGE IS 8 OHMS.

IF YOU CONNECT AND USE THE PA202 WITH A LOWER

SPEAKER IMPEDANCE THAN LISTED ABOVE YOU

WILL DAMAGE THE UNIT AND POSSIBLY OTHER

EQUIPMENT THAT IS CONNECTED TO THE PA202.

NOTE: THIS MANUAL ASSUMES THE USER HAS A WORKING KNOWL-

EDGE OF AUDIO ELECTRONICS, BALANCED AND UNBALANCED CON-

NECTIONS, AND PROPER SIGNAL LEVEL SETTING.

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 instal-

lation and setup is crucial. If you are experiencing distortion turning the

Limiter on may help but it is not intended for total dynamics control. Its

primary function is to help prevent one time very loud signals like drop-

ping a microphone or loud program material that is temporary.

LIMITER EXPLANATION:

The holes in the back and

side of the PA202 are for the

attachment of a zip tie (not

included). For power cord

strain relief as needed.
