The Power of Protea

PE-Series (Protea Enabled) amplifiers are far more than just another series of amplifier. The six 2-channel models boast a remarkable range of power all the way from 400 to 1900 watts per channel (@ 4 ohms), and their Ethernet functionalities certainly increase their already high value in professional audio applications. All PE-Series amplifiers are 2RU high, weigh less than 24lbs and will power 2, 4 or 8 ohm loads. Each amplifier also includes LED indicators for power, standby, protect, bridge mono, parallel mono and network communications, and are located on the left side of the front panel. On the right side, each channel has temperature and current indicators as well as a four-step signal meter.

PE-Series amplifiers incorporate state of the art control and power technologies. Each amplifier in the series can be monitored and controlled through the Ethernet port on the rear panel using standard, affordable Ethernet hardware and Protea NE Software™. This software gives you access to many diverse features, including real time control of input attenuation, channel mute, channel polarity, and even enables you to remotely power the unit on or off. Protea NE also allows you to monitor I/O level, protect, temperature, output current and clipping.

Ashly Audio has maintained that one of the secrets to superb sound and dependability is well-thought-out design and meticulous execution. Ashly's PE-Series takes that philosophy and multiplies it ten-fold. When your next project requires high performance amplifiers with superb sound, reliability, remote control and more, Ashly’s PE-Series power amplifiers have been designed to meet and even exceed the needs of both portable and long-term installation applications.

Amplifier Specifications

Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
>98 dB
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
20 - 20000 Hz
Input Sensitivity
This is the input sensitivity of the amplifier.
1.4 volts
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Voltage Gain
This is the voltage gain of the amplifier measured in decibels.
36 dB
Cooling Options
These are the different cooling systems used in the amplifier to keep it cool.
Cooling Fan
These are the type of input connections that the amplifier has.
1/4" TRS
These are the types of output connections that the amplifier has.
