Architects Specifications

PE-Series, 2-Channel Amplifiers with Ethernet Control
The power amplifiers shall consist of six separate models (800,
1200, 1800, 2400, 3000, and 3800), being of two channels, and
shall deliver a minimum power ranging from 200 to 1100 watts
RMS per channel into 8 ohm loads and ranging from 400 to 1900
watts RMS per channel into 4 ohms depending on the model
being used. When switched into Bridged-Mono mode, the ampli-
fier in use shall deliver a range from 800 to 3800 watts RMS into
8 ohms. All amplifiers shall have the ability for input attenua-
tion, channel mute, channel polarity, input level, output voltage,
output current, clipping, temperature, and power on/off be con-
trolled or monitored through the standard, built-in Ethernet port
using Protea ne Software™.
The amplifiers shall have the capability to replace the input mod-
ule with either a 32 bit/96kHz, Protea ne DSP module featuring
both analog and digital (AES3) inputs, two additional processed
output channels and extensive digital signal processing or the
PNE-C2 CobraNet module.
Dimensions of the amplifiers shall be 19"W x 3.5"H x 15.5"D,
with a weight range of 22 to 24 pounds. The amplifiers shall uti-
lize a state-of-the-art, efficient, two-stage high speed switched
mode power supply. Cooling shall be accomplished by the use
of a temperature sensitive variable speed fan with front to back
airflow.
The amplifier shall have a selectable input gain of 26dB, 32dB
or 1.4V. Frequency response shall be 20 Hz - 20 kHz, +/- 0.15
dB. Hum and noise shall range from >98dB to 112dB below full
output (20Hz to 20KHz A-weighted) and SMPTE intermodulation
distortion shall be <.01% (8 ohm load, 10dB below rated power).
Total Harmonic Distortion (20Hz - 20KHz at 8 ohms) shall be
<.01% (8 ohm load, 10dB below rated power, 20Hz-10 kHz).
Each amplifier channel shall be supplied with a calibrated stepped
input attenuator located on the front panel with the capability of
the attenuators to be disabled. Each pair of inputs shall have a
selectable, bypassable high pass filter of 12dB/octave at 30Hz
and 50Hz, a switch to select stereo or mono mode and a switch
to select dual or bridge mode. There shall be an input ground
switch located on the rear panel to select chassis or floating
ground operation and a selectable clip limiter with off, slow, and
fast settings.
The inputs shall be active balanced design, with an impedance
of 20K ohm with a maximum input level of +21dBu. Input con-
nections shall be XLR-1/4" Neutrik combo connectors and 6-pin
Euroblock. XLR male connectors shall be provided for looping to
additional amplifiers. Output connectors shall be locking Neutrik
Speakon. Models 800 and 1200 shall have a 4 position screw ter-
minal strip with safety cover as an additional output.
The amplifiers shall have front panel indicators for power, stand-
by, protect, bridged mono, parallel mono, and data communica-
tions. Each channel shall have signal indicators for clip, -6 dB,
-12 dB, -18 dB levels, temp, output current.
The amplifier shall have built in protection for inrush current,
temperature, output DC, SOA of power transistors, output over-
current and mains power.
The amplifiers shall be capable of operation by means of its own
built-in power supply connected to 110 - 125VAC, 220 - 250VAC,
50/60Hz.
The amplifier shall be covered under a full limited warranty of not
less than five years. The amplifier shall be a PE-Series model,
manufactured by Ashly Audio, Inc. of Rochester, New York.
