Brand New Polk Audio PA200.4 amplifier for sale. $125 shipped plus Paypal fees.
Specs:
50 watts x 4 (2 ohm) or 35 watts x 4 (4 ohm) continuous power in 4 channel mode. 100 watts x 2 (4 ohm) continuous dual bridge mono/2 channel mode.
80 x 4 (2 ohm) dynamic power.
CEA-2006 Compliant specifications for true, accurate power ratings.
4-channel, dual bridge-mono (2-channel), or dual simultaneous stereo/mono operation provide a variety of configurations and setups: 4-channel for front and rear speakers; 2 speakers and a sub; as 2 subwoofers; or as 2 subs and 4-channels in passive-tri mode.
2 ohm stable 4-channel operation.
High-speed MOSFET switching power supply and high current Bipolar Output Transistors pump maximum voltage and high current to your speakers or subwoofers.
Double Layer Fiberglass Epoxy Printed Circuit Boards for more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. Efficient layout packs more circuitry, with tighter component tolerances, into a smaller circuit board for a smaller overall amp footprint.
6-Way Smart System Protection (SSP) circuits: Power and Ground-Reversal Protection, Thermal and Short Protection, Current Overdraw and Low Impedance Protection circuits with auto-Standby Mode ensure safety, reliability and durability.
