PE Series (Protea Enabled) amplifiers are high-power, high-efficiency, lightweight amplifiers
incorporating the latest in power and control technologies. Each amplifier can be controlled
and monitored through the built-in Ethernet port using Proteane Software?. Proteane gives
users access to many features, including: input attenuation, channel mute, channel polarity,
nput level, output voltage, output current, clipping, temperature, and power on/off.
By adding Ashly?s Protea DSP technology and control to an amplifier, comprehensive and easy
to use audio system has been designed. With the introduction of the PE Series amplifiers,
Protea technology has been taken to the next level. Proteane Software allows you to setup, control
and monitor PE Series amplifiers using standard, inexpensive, readily-available Ethernet hardware.
Nothing proprietary here! Control anywhere from one to hundreds of amps, as well as your Protea
Series processors, on- or off-site with our intuitive and friendly Proteane Software.
There are six models of PE Series amplifiers, all of which share the same PE feature set, that
cover a wide range of power requirements from 400W to 1900W per channel @4 ohms. Each
utilizes a 2-stage high-efficiency switched mode power supply, which provides a high-power-to-weight
ratio. All are two rack units high and weigh less than 24lbs! All models will drive 2, 4 or 8 ohm loads.
Input connections are via XLR-1/4? Neutrik combo connectors and 6-pin Euroblock. XLR male
connectors are also provided for looping to additional amplifiers. Output connectors are locking
Neutrik Speakon (NL-4) on all models and 4 position screw terminal strip with safety cover on
models 800 and 1200.
Each PE Series amplifier provides on-board analog processing, including a selectable subsonic filter,
a selectable clip-limiter and an input-sensitivity selector, which can optimize the amplifier for load and
the many devices that can drive it. Plus, we?ve included an array of output current and temp indicators
to monitor various operating parameters. It?s easy to tell at a glance, for example, the status of the load
being driven (i.e. ?are my drivers working??). The PE Series also provides DC voltage control of the
calibrated Input attenuators, which makes it a snap to control volume from remote locations, and Remote
Power Turn-on/-off with sequential power on/off circuitry built right into the amplifier.
Need more? Proteane DSP Cards can be installed as needed. Their SHARC 32-bit/96kHz processor
enables 24-bit AD/DA, analog and digital (AES3) inputs. Each offers two additional processed output
channels to drive additional amplifier channels. Our current DSP library includes Graphic, Parametric,
Notch and Shelving Equalization, High-, Low- and All-Pass Filters (HPF/LPF/APF) with up to 48dB/
Octave slopes, Delay, Compressor/Limiter, Gate, Gain, Signal Generators (sinewave, white and pink
noise) and Matrix Routing.
Proteane mobile is a software application enabling you wireless control of PE-Series amplifiers and the
DSP-1 and DSP-2 Option Cards for the PE-Series amplifiers.
The PE-2400, PE-3000 and PE-3800 are capable of driving 70 Volt systems. Power specifications are:
PE-2400: 1200W per channel, PE-3000: 1500W per channel and PE-3800: 1700W per channel.
Ashly has long believed that the secret to great sound and reliability is intelligent design and meticulous
execution. Our PE Series takes that philosophy and multiplies it ten-fold. Optimized for cool operation,
modularity, ultimate compatibility and maximum performance, the PE Series is the amplifier line you?ve
been waiting for.
When your next project requires high performance amplifiers with superb sound, reliability, remote control
and more, Ashly Audio?s PE Series of remote-controlled power amplifiers have been designed to meet the
needs of both portable and installation applications.
