Ultra-High Sonic Quality

Ashly's SRA-Series Power Amplifiers make it super easy to get what you need at an affordable price. SRA-Series amplifiers are designed to power 4 or 8 ohm loads and come housed in a slim 1RU chassis weighing a mere 10 lbs. or less. The 150W models are amply (no pun intended) capable of directly driving lines of constant 25V. Class-D amplifier circuitry and switch-mode power supplies make for a very power-efficient unit that's perfect for a broad variety of low wattage applications.

The SRA-Series incorporates state of the art technological advancements to deliver highly-efficient amplifiers ideal for installations with moderate power necessities. Four models are available in 2 and 4-channel setups with RMS power ratings of 75W and 150W per channel (@ 4 ohms).

Some of the SRA-Series features include: very low noise, extensive protection circuitry, Euroblock I/O, attenuators for individual channels, clip alert and signal present status LEDs for each channel, rear panel switches for selection between two settings of input sensitivity, HPF frequencies, normal or bridged mode, remote power turn-on/off and customizable power-on delay (up to 8 seconds). In addition, the two-channel models have stereo headphone jacks on the front panel.

All Ashly SRA-Series amplifiers are convection-cooled, which means almost no need for maintenance after initial installation, AND no irritating noise from the fan. With the SRA-Series amplifiers, you get the dependability, ultra-high sonic quality and rugged construction that consumers expect from the Ashly name.

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
Voltage Gain
This is the voltage gain of the amplifier measured in decibels.
36 dB
Cooling Options
