DENON PMA-520AE

Denon Singapore

GENERAL FEATURES

High Current (HC) Single-Push-Pull Circuit for musical detail and power
The 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 interference 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.
