The PX2122 is designed for long-throw mains applications, typically arrayed with two or more units.

• 4 channels in one compact rack-efficient unit
• 1000W per channel
• 70/100 V operation for distributed systems
• Class-D design optimum efficiency
• Slot for optional RCM-810 module, allowing IRIS-Net control and monitoring
• IRIS-Net selection of each channel´s impedance 2-10 Ω in 0.1 Ω steps
• Rear-mounted attenuators
• Switchable 50Hz high-pass filter Hi-Z mode
• Complete protection: thermal, overload, shorts, HF, DC, back-EMF, inrush current
• Phoenix-type input and output connections
• Remote power-on/off contact
• Programmable power-on delay settings
• Front-to-rear fans
