Default Pa500.4

* 125 watts x 4 (2 ohm) continuous power, 250 x 4 (2 ohm) dynamic power or 250 watts x 2 (4 ohm) continuous 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.

* Great Looks and Functionality Anodized extruded brushed-aluminum cover for maximum heat dissipation and great looks!
* Cast aluminum textured end caps for optimized heat dissipation and hiding of connectors. Solid aluminum logo and model panel back lit in cobalt blue.
* Fully adjustable 12 dB/octave high or low-pass crossover. Defeatable for full range (flat) operation.
* Switchable 8 dB bass boost at 40Hz for extra bass thump.
* Variable input gain optimizes match with different signal sources (250mv to 7.5V).
* RCA Outputs (front channels only) for easy daisy chaining of other amplifiers.
* Mounting hardware with rubber isolation grommets and extra fuses included.
* Light Bar/Fan Output- Connect an optional LED light bar or cooling fan for custom installations.
* Multi-Color Status LED gives instant information on amplifier operation.
* Remote Subwoofer Level Adjuster for rear channels included.
