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
came with the amplifier (visit Ashly.com to check for software updates). Protea
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 (20Hz­20kHz, 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

Installation

PE-Series amplifiers are designed for use in both fixed and mobile sound systems. Each
amplifier is shipped (unless otherwise specified) with the following factory settings:

Front panel: Rear panel:
On/Off Switch = Off
Attenuators = 

Before connecting to mains power, make sure that the switches are set to the configuration
needed for your particular application. Always switch the amplifier off before making any
changes to the settings. Failure to do so could result in damage to the unit or other components
in your system. CAUTION: When mounting or connecting the amplifier, always disconnect it
from the mains. Use four screws and washers when mounting the amplifier to the front rack
rails. Rear support is also recommended, especially for mobile or touring use. To reduce the
risk of fire or electric shock, do not expose this apparatus to rain or moisture.

Requirements

PE-series amplifiers have specific physical, electrical and signal requirements for proper
operation. These requirements will vary depending on your specific application, setup, and
the settings on the amplifier. When setting up and testing your system, please take special
care to double check all connections and settings. Please refer to the specifications section
of this manual for specific input, output and other figures.

Typical Applications

The most common
use of a PE-Series
amplifier is a 2­channel source
driving 2 speaker
channels. In this
illustration, the PE­Series amplifier is
receiving a signal and
then ‘returns’ it to a
second amplifier
using the provided
connectors. The
amplifier is in
STEREO mode.

Because of their efficient
and high-power design,
PE-Series amplifiers are
well suited to single
channel output to mono
speaker load such as a
subwoofer. This
illustration shows both
PARALLEL and
BRIDGED output
connections using a
single input signal.

Connectors & Polarity

PE-Series amplifiers utilize several different professional audio connectors. The
Euroblock (and Screw-Terminals on models 800 & 1200) connectors are clearly marked
on the amplifier’s rear panel and are straightforward. The connection polarity for the other
three types of connectors (XLR, TRS, and Speakon) are less obvious. The diagrams below
show how each connector should be wired for proper operation. Be sure to read the
Operation section of this manual for important information on the three operating modes.

Operation

The amplifier’s On/Off Switch is a rocker-type switch located on the left side of the front
panel. Turning on the amplifier initiates start-up by activating the inrush current limiter.
During power up, the Clip and Signal LEDs from both channels will light up in red for a few
seconds.

When using the remote On/Off function, the main On/Off switch must remain in the On
position. See page 11 for more information on remote On/Off connections.

NOTE: The power switch does NOT isolate the appliance from mains. Make sure the mains
power socket or an alternative disconnect device is near by and easily accessible. When the
product is connected to mains, the line-filter and the input of the fuse are energized.

2 Channel (Stereo) Mode

In this mode, the amplifier’s two channels operate fully independent of each other. Each
signal enters the unit and is amplified separately.

Parallel-Mono Mode

In this mode, a single input signal (connected to channel 1) is connected to the two output
channels. The output terminals of the two channels are configured in parallel using an
internal relay. The (single) load is connected either to the output of channel 1 or to that of
channel 2 (as if in stereo). While the total output of the amplifier remains the same and the
output voltage level is also the same as in stereo operation, the minimum impedance that
can be connected is reduced by half because the current capability is doubled. Only the
Channel 1 attenuator is active. The Channel 2 attenuator should be turned down to zero.
This mode is useful when identical loudspeakers are to be operated with the same power.

IMPORTANT: When connecting speaker cabinets in parallel, always use all the contacts
in both SPEAKON connectors. If not, this can cause permanent damage to the connectors
and considerably reduce performance.

Bridged Mono Mode

In this mode, a single input (connected to channel 1) is connected to the two output
channels that have been ‘Bridged” together. Each output channel processes the signal, but
the polarity of channel 2 is reversed. The (single) load is connected between the two
positive channel outputs using a suitably connected SPEAKON connector. While the total
output of the amplifier remains the same, both the available output voltage and the
minimum impedance that can be connected are doubled, as compared with stereo
operation. Only Channel 1 is active. A signal feeding Channel 2 will have no effect on the
output.

WARNING! In Mono-Bridge mode RMS output voltages as high as 230 V. Wiring to
the speaker loads must conform to NEC Class 3 safety standards or its equivalent. All
customer specific cables should only be manufactured by qualified personnel.

WARNING! Terminals marked with are HAZARDOUS LIVE. External wiring to
these terminals/connectors requires installation by trained personnel, or pre­manufactured cables.
