High End 225W Monoblock power amplifier

When it comes to playing music or delivering sound through a loudspeaker system, there are a few things to consider. While it may seem like the power amplifier is the key component needed to drive the speakers, there is actually much more to it. Precisely controlling the drivers in the system is essential for achieving clear, accurate sound that is of high quality and pleasing to the ears. By carefully monitoring the behavior of the individual drivers in the system, it is possible to optimize their performance and ensure that every note and element of the audio is reproduced as the sound engineer intended. This can be achieved through the use of advanced control systems and technology that allow for greater precision and accuracy in sound reproduction, making it possible to achieve exceptional results in a wide range of musical genres and live performance settings.

Loudspeaker drivers contain a vital component that is responsible for producing sound: the moving element. Typically, this moving element is implemented as a voice coil, however it is important to note that it is actually a linear moving motor – complete with a membrane attached to it. In order for sound to be accurately produced, this motor must move in both backward and forward directions in a precise manner, tracking the waveform that is applied to it with incredible speed and accuracy. This delicate balancing act requires the motor to exert forceful pushing, stopping, and pulling to accurately replicate the original sound wave. By doing so, the driver is able to produce high-fidelity sound that is both beautiful and accurate to the original source.

The smooth and flawless functioning of a speaker depends on the coordination between its various components, including the voice coil assembly and the membrane. In order for the voice coil assembly and the membrane to function effectively, they need to be pulled and pushed by a surge of energy that comes from the amplifier system. This is where the quality of the amplifier system plays a crucial role. The amplifier system needs to have an efficient energy supply that is capable of handling the energy requirements of the speaker at all times.

To put it simply, the amplifier system needs to provide a sufficient amount of energy to move the mass of the voice coil assembly and the membrane, which can require a significant amount of energy. This is because the membrane needs to move the air in order to create sound, and this air needs to be moved with precision. Therefore, a better amplifier system will lead to an improved sound quality, as it can more effectively provide the energy needed to operate the speaker components.

Our team has recently released a top-quality product known as the PWA01 amplifier module. This amplifier module has been designed with the sole purpose of delivering the best possible sound output. Moreover, when it is combined with the appropriate power supply, it is capable of driving some of the most demanding loudspeaker systems with great ease. We take pride in the fact that our amplifier module has been manufactured with the highest standards, ensuring a long lifespan of the product. Thus, if you are looking for an amplifier module that will boost the sound quality of your music and simultaneously give the performance that you desire, the PWA01 amplifier module is definitely a wise investment. It offers the perfect combination of high quality, durability, and excellent sound performance which every music lover seeks.

It is important to note that the specifications of this particular amplifier are top-notch. However, during the design phase, we wanted to ensure that not only were the electrical properties of the product great, but that the sound quality was impeccable as well. Thus, in addition to measuring and developing to the best electrical properties, we also conducted listening tests and selected only the best components to use in the amplifier.

The result of these efforts is an amplifier that has an exceptional sound quality that can easily rival other more expensive products in the High-End market. The module itself is expertly crafted, built on a robust 5mm aluminum plate and mounted to a large and heavy 200 x 150 x 40 mm heat-sink that ensures the amplifier operates at an optimal temperature level. These elements, combined with our commitment to quality, make this amplifier a must-have for any enthusiast seeking an unparalleled listening experience.

The genesis of this phenomenal project rests upon the Audio products PWA01 power amplifier module. What makes this module stand out is its incredible power that stems from its all transistor vintage amplifier design, combined with the latest and most advanced modern components such as the revered dual Sanken driver transistors, Toshiba power transistors, and Nichicon audio-grade capacitors. This perfect symphony of past and present components is what gives this module an unmistakable voice that captures the essence of vintage clarity and modern power like none other. The end result is an amplifier like no other, that delivers clean, clear, and dynamic sound to any listening environment.

Some specifications

RMS power:
225W 4 Ohm 5-50.000 Hz
130W 8 Ohm 5-50.000 Hz

Dynamic power:
475W 4 Ohm 20-20.000 Hz


Next to the power amplifier module it incorporates an audiophile power supply PSP01 from Audio products with a large capacitor bank of 120.000 µF, 60.000 µF per voltage rail and a 2 x 35V 9A 625VA torroidal power transformer. 



This power supply is able to deliver very high currents instantaneously to have the power amplifier control even the most difficult loudspeaker system.


To control this all an Audio products power supply controller IRC01C is used. This controller has a mains filter to reject EMI and enables you to switch the power on or off with a single ‘illuminated’ push button. It also has an input to detect incoming audio signals and switch the power supply on or off depending on signal input to the amplifier. Next to this the controller accepts 12V trigger signals from the connected pre-amplifier to switch the power on and off.
