Product Features

The Accuphase A-48 is a high-performance stereo power amplifier that is designed to provide exceptional audio performance. The A-48 can easily drive even the most demanding speakers with a power output of up to 180 watts per channel into 8 ohms. The balanced signal path and high-quality power supply of the amplifier help to reduce noise and distortion in the audio signal. The A48 also includes advanced protection circuitry to protect the amplifier and connected equipment from damage caused by electrical faults or other issues. The Accuphase A 48 is a top-of-the-line amplifier for audiophiles and music enthusiasts, thanks to its exceptional power output and advanced features.

MOS-FETs with high power density
In its output stage, the Accuphase A48 power amplifier employs advanced Power MOS-FETs, which provide a number of advantages over traditional bipolar transistors. MOS-FETs have lower distortion and higher efficiency, which results in better audio performance and lower power consumption. To provide exceptional power output and control, the MOS-FETs are arranged in a triple parallel configuration. The Accuphas- A-48 power amplifier delivers high-quality audio performance and efficient operation in a compact and elegant package thanks to its use of advanced MOS-FET technology.

Powerful power supply
The A-48 Accuphase power amplifier is equipped with a high-quality power supply that provides stable and dependable power to the amplifier's circuits. A large toroidal transformer is included in the power supply, which helps to reduce noise and interference in the audio signal. A bank of high-capacity capacitors is also included in the power supply, allowing for fast and responsive power delivery to the amplifier's output stage. The Accuphase 48A can deliver exceptional audio performance with excellent dynamics and control thanks to its strong and stable power supply, making it a top choice for audiophiles and music enthusiasts.

The principle of an instrument amplifier
In its input stage, the Accuphase 48-A power amplifier employs a high-performance instrumentation amplifier circuit, which provides several advantages over traditional amplifier designs. The instrumentation amplifier circuit has a high input impedance, low noise, and excellent common-mode rejection, which results in excellent audio performance with minimal distortion and interference. A feedback loop is also included in the instrumentation amplifier, which aids in maintaining stable and accurate amplification even with complex or difficult audio signals. The Accuphase-A-48 power amplifier delivers exceptional audio performance with excellent accuracy and clarity thanks to its use of advanced instrumentation amplifier technology.

Dedicated power source
The A-48 Accuphase  power amplifier has a dedicated power supply for its input stage and control circuitry, which helps to isolate these circuits from the amplifier's output stage power supply. This dedicated power supply ensures that the sensitive input and control circuits receive clean and stable power free of interference or noise from the amplifier's output stage. The A-48-Accuphase can deliver exceptional audio performance with accurate and detailed sound reproduction thanks to its dedicated power supply.

Two large speaker terminal sets
The Accuphase-A 48 power amplifier has two sets of large speaker terminals, allowing for the simple connection of two distinct sets of speakers. This feature is particularly useful for users who want to connect multiple sets of speakers to their audio system, such as in a home theater or multi-room audio system. Users can switch between different sets of speakers or use them simultaneously with the Accuphase-A-48, providing greater flexibility and customization in their audio setup.

Finally, the Accuphase A-48 power amplifier is a high-performance amplifier with a powerful power supply, dedicated input and control circuitry power supply, and instrumentation amplifier principle to deliver exceptional audio performance. Its use of Power MOS-FETs ensures high output power with minimal distortion, and its two sets of large speaker terminals make it simple to connect multiple sets of speakers.
