The versatile PX series power amplifiers lineup combines intelligent processing with high output power to meet the requirements of a vast range of sound reinforcement environments. 800W x 2 at 8 ohms / 1050W x 2 at 4 ohms.
The on-board DSP functions include a PEQ, a delay, a crossover, and a limiter. They allow for detailed configuration of parameters such as input & output routing, input sensitivity, amp gain, and speaker impedance. The D-Control multi-band dynamic processor delivers a clear and consistent sound at any output level by shaping the frequency response of each speaker for either front-of-house or monitor configurations.
The Configuration Wizard helps save time during setup by assigning optimized speaker settings that match your system configuration. It can be used in basic mode for quick setup or advanced mode for more precise control over DSP parameters. You can store up to eight presets, which can be saved to a USB drive for use with other amplifiers and setups.
For secure operation, the panel-locking function ensures that your settings remain safe. With its sturdy frame and carrying handle, the PX8 is built to withstand extended road use.
