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.
