Features - PMA-520AE

The PMA-520AE integrated amplifier features a High-Current Single-Push-Pull circuitry to achieve both strength and detail in music playback, which is Denon’s focus for its pure audio amplifiers. The relay switch used for CD and Phono input contains an inert gas to prevent the occurrence of noise that can negatively affect the signal. In addition, durable parts strictly selected for their contribution to sound quality, such as the large-capacity block capacitor for the power supply circuit, high-quality sound carbon resistors, and high-quality sound capacitors, are also used. Each individual part employed in configuring the circuits reflects this emphasis on high fidelity. For improved convenience, the remote control unit that comes with the PMA-520AE includes the main functions that control Denon CD players.

New features:

• Improved sound quality
• Newly-designed system remote control
• ECO friendly with low power consumption in stand by and auto power off
• New higher quality speaker terminals
