The PowerPro series comprises four models - PS-200, PS-400, PS-800 and PS-1400. The PS-200 (12kg) and PS-400 (13kg) are 1RU high and offer power ratings of 100W and 200W per channel @ 4 ohms respectively. The PS-800 (18kg) and the PS-1400 (21kg), largest of the PowerPro line, are 2RU high and provide 450W and 700W per channel @ 4 ohms. The amplifiers offer XLR and 1/4 " TSR connectors for the inputs and both Speakon NL-4 and binding posts on the outputs (PS-800 and PS-1400 only).
Rear located switches are available for ground lift, operational mode (stereo-bridge-parallel) and input sensitivity selection (0.75 V, 1.0 V and 1.4 V). The low-noise fans force air from back to front and offer both quiet and cool operation while the high energy toroidal transformer saves weight. Each channel is individually protected against output short-circuits, overloading and overheating. The power supply is protected against short-circuits, voltage and current overloading which triggers the standby mode. Clip, protection and idle LED indicators are provided for easy troubleshooting.
