PX-1000.4 is a four-channel car audio amplifier with full Class A/B operation for stereo and four-channel configurations. Its output ratings are 4 x 250 watts at 2 Ohms and 4 x 125 watts at 4 Ohms. QTD, or Quick Thermal Dispersion, technology adds aluminum to the heatsink to support heat dispersion during operation. A pulse-width-modulated power supply and SEPP, or Single Ended Push Pull, output technology define the power section. LED power and protect indicators show operating status, while slow-unmute soft-start turn-on controls startup behavior. Level inputs connect the unit to compatible vehicle audio systems, and preamp RCA outputs allow daisy chaining multiple amps. Variable high-pass filtering ranges from 120 to 3,000 Hz, and variable low-pass filtering ranges from 50 to 250 Hz. Variable bass boost provides 0 to plus 12 dB at 45 Hz. The chassis measures 12.6 x 10.8 x 3.7 in and weighs 5.4 lb.
