PE-Series (Protea Enabled) amplifi ers are high-power, high-effi ciency, lightweight amplifi ers incorporating the latest
in power and control technologies. Each amplifi er can be controlled and monitored through the built-in Ethernet port

channel polarity, input level, output voltage, output current, clipping, temperature, and power on/off.
The 800, 1200, 1800, 2400, 3000 and 3800 range in power from 400 watts to 1900 watts per channel at 4 ohms
(20Hz-20kHz, 0.05% THD). All models will drive 2, 4 or 8 ohm loads.
All amplifi ers are 2RU, weigh 20 pounds and utilize a state-of-the-art, effi cient, high speed switched mode power sup-
ply. Additionally, DC voltage control of the input level and remote power on/off are standard features.
Input connections are via XLR-1/4” Neutrik combo connectors and 6-pin Euroblock. XLR male connectors are also
provided for looping to additional amplifi ers. Output connectors are locking Neutrik Speakon and 4 position screw ter-
minal strip with safety cover. Switches on the rear panel include a selectable HPF (Out, 30Hz and 50Hz), Clip Limiter
(Off, Slow, and Fast), Input Ground Lift, Gain (26dB, 32dB and 1.4V) and Operation Mode (Stereo, Bridged Mono and
