High-Quality Components for a Superior Listening Experience
The PA40 amplifier is designed with premium components to ensure excellent sound quality and reliable operation, featuring overcurrent, overheating, and under-voltage protection circuits for a seamless and safe listening experience. At its core is the NJU7391A electronic volume control chip from Nisshinbo Micro Devices, a 2-channel chip that provides low noise, low distortion, and supports surround sound and tone control to enhance audio performance. Complementing this is the MA5332 Class D amplifier chip from Infineon, which offers standard protection and reliable performance in various environments. With its high energy conversion efficiency, the PA40 minimizes heat generation and energy consumption.
Audiophile-Level Sound Quality
The PA40 amplifier delivers exceptional audio performance with its low distortion, low noise, and wide dynamic range. It surpasses traditional amplifiers in sound quality, offering clearer audio, reduced noise, and enhanced low-frequency response.
Gold-Plated Terminals
The PA40 amplifier is equipped with high-quality gold-plated input and output terminals, designed to offer superior durability and conductivity. These terminals not only ensure a longer service life by resisting corrosion but also reduce the need for frequent maintenance, providing a stable and reliable connection for optimal audio performance.
Built-in Power Supply
The PA40 features a built-in power supply, eliminating the need for additional adapters and reducing cable clutter to keep your workspace neat. This design not only minimizes potential electromagnetic interference from external adapters but also ensures a stable power source, optimizing the amplifier's overall performance. Additionally, the built-in power supply makes the unit easier to carry, install, and move, offering convenience and portability.
Remote Control
The PA40 comes with an easy-to-use remote control, allowing you to conveniently power on/off, switch functions, adjust volume, and turn off the screen from a distance. For detailed operation instructions, please refer to the user manual.
EQ, Bass, and Treble Adjustment
While powered on, each short press of the knob cycles through adjustments for "Volume," "EQ," "Bass," "Treble," "Gain," and "Brightness," allowing you to fine-tune your audio settings with ease.
