Soundastic Power Amplifier Reference Power

The Reference Power amplifier is the latest proposal from Soundastic.

It is a dual mono (balanced) power amplifier, which is a further development of a proven design. The power supply to both channels is 100% independent of each other through two very efficient 500VA toroidal transformers and four Nippon Chemi-Con capacitors.

Reference Power is equipped with RCA and XLR inputs and can operate as a mono or stereo amplifier.

Both channels work in a balanced circuit.

The amplifier works in class AB with the power of 150W per channel into 8 Ω and 280W per channel into a load of 4 Ω.

The constructors used a patented solution (patent no. 176514), which affects:

• Audio neutrality – guaranteed by using only JFET transistors and symmetrical inputs in the design. In the signal circuit, the amplifiers do not have a capacitor.
• No supply voltage distortion – under dynamic load conditions, waveforms that are not mathematically definable are eliminated, and voltage fluctuations do not affect the bridge stability. This reduces non-linear distortion and improves the frequency response of the amplifier.

Also, this influences the quality of the audio signals processed and determines the high technical performance of the device.

The housing, in which the electronics is placed, is made of a metal alloy whose anti-magnetic nature guarantees a significant resistance to external interference, while the front plate is made of aluminum alloys used in the aviation industry.
