Operator Manual – PE Series Amplifiers

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 Protea

amplifier (visit Ashly.com to check for software updates). Protea

features, including: input attenuation, channel mute, channel polarity, input level, output voltage,

output current, clipping, temperature and remote standby.

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

under 24 pounds and utilizes a state-of-the-art, efficient, high speed switched mode power

supply. DC voltage control of the input level and remote standby 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, and screw terminal strip with safety cover.

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 100°C, both channels are muted.

Mains Protections – protection within the power supply includes: Inrush Current

Limitation, Mains Over Voltage Detection, Mains Failure Detection, and Fuse

Protection.
