The PE Series

PE-Series (Protea Enabled) amplifiers are high-power, high-efficiency, lightweight amplifiers incorporating the latest amplifier technologies. Each amplifier can be controlled and monitored through the Ethernet port using ProteaNE Software™ included on the CD that came with the amplifier (visit Ashly.com to check for software updates). ProteaNE gives users access to many features, including: input attenuation, channel mute, channel polarity, input level, output voltage, output current, clipping, temperature, and monitoring for power on/off.

The series provides a wide power range of 400 to 1900 watts per channel at 4 ohms (20Hz- 20kHz, 0.05% THD). All models will drive 2, 4 or 8 ohm loads. Each models is 2RU, weighs 20 pounds and utilizes a state-of-the-art, efficient, high speed switched mode power supply. DC voltage control of the input level and remote power on/off are among the many standard features.

Input connections are via XLR/TRS Neutrik Combo, and 6-pin Euroblock connectors. XLR male connectors are also provided for looping to additional amplifiers.

Output connectors are locking Neutrik Speakon on all models (models 800 & 1200 also have screw terminal strips with safety covers). Switches on the rear panel include: selectable High Pass Filters, Clip Limiter, Ground Lift, Gain and Operation Mode.

Protection

PE-Series Amplifiers come standard with several protection circuits:

Clip Limiter – On overdrive the clip detection triggers the Attack-Release Circuit delivering control voltage for gain reduction.

SOA Protection - If the power transistors leave their Safe Operation Area, the SOA-protection switches back the current rail of the respective channel.

DC Protection - Each output is monitored for DC voltage. If thresholds are exceeded, the corresponding channel will be muted. Minor DC occurrences (once resolved) will return the amplifier to normal. If the DC condition is severe the amplifier will enter standby.

DC Servo - PE-Series has a DC Servo to prevent DC Offset at the output. Over Current Protection - Is controlled in the output stage.

Thermal Protection - When the internal temperature is below 40°C the fan runs at its slowest speed. Above 40°C the speed is increased until it reaches its maximum value. If the temperature exceeds 85°C, the input on that channel is reduced. If the temperature exceeds 100°C, the power supply is switched off. Mains Protections – protection within the power supply includes: Inrush Current Limitation, Mains Over Voltage Detection, Mains Failure Detection, and Fuse Protection
