The Denon 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 Denon PMA-520AE includes the main functions that control Denon CD players.

High Current (HC) Single-Push-Pull Circuit for musical detail and power
The Denon PMA-520AE incorporates HC transistors with 2 to 3 times the electrical current supply capability of conventional power transistors for audio. Denon’s acclaimed HC Single-Push-Pull Circuit has been inherited from its high-end models which, together with a fully discrete amplifier design, produces a powerful sound filled with beautiful musical details.

High-speed, high-capacity power supplycircuit for HC Single-Push-Pull
The PMA-520AE’s power circuit uses a block capacitor that Denon engineers have jointly developed with a parts manufacturer and a Schottkybarrier diode that features low internal resistance for low loss, short recovery time, and negligible rectifying noise. This highly stable electrical current supply further brings out the expressive power of sound produced by the HC Single-Push-Pull Circuit.

Wide dynamic range, supporting high-grade audio sources
The PMA-520AE’s tone control and power amplifier circuit have been carefully adjusted to secure a frequency response of up to 100 kHz during actual use. Also, improvements in the volume circuit suppress noise in the amplifier to achieve high sonic resolution. These features and others give the PMA-520AE plenty of latitude to handle the wide dynamic range of high-grade audio sources such as Super Audio CD and DVD-Audio.

Main transformer with separate power supplies for analogue
The coiled wire within the power transformer for the audio signal and control circuits has been separated to eliminate mutual inter-ference and adverse influences on sound quality. The PMA-520AE also has a separate transformer to minimize power consumption when in “standby”. Ensuring a more environmentally friendly design.
