The Denon PMA510AE amplifier features 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. Denon's engineers have used their extensive knowledge of audio technology to create an integrated amplifier that is a step up in class from previous designs. For improved convenience, the remote control unit that comes with the Denon PMA-510AE integrated amplifier includes the main functions that control DENON CD players.

The Denon PMA510 AE integrated amplifier 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.

The Denon PMA-510AE's power circuit uses a block capacitor that DENON engineers have jointly developed with a parts manufacturer and a Schottky-barrier 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.

The Denon PMA510AE amplifier'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-510AE plenty of latitude to handle the wide dynamic range of high-grade audio sources such as Super Audio CD and DVD-Audio. 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 Denon PMA-510AE also has a separate transformer to minimize power consumption when in "standby". Ensuring a more environmentally friendly design
the Denon PMA510AE integrated amplifier employs Denon's Signal Level Divided Construction (SLDC) in which the circuits for small and large signals, the micro-processor, and other circuits are separated in an ideal manner to minimize mutual interference

The Denon PMA510 AE includes a Source Direct function that allows the audio signal to bypass the Bass, Treble, Loudness, and Balance control circuits and maintain its purity for optimum sound transparency during playback. This Source Direct function works for all inputs.

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 sound quality.
The Denon PMA 510AE's remote controls the main volume, function switching, muting, and remote power on/off (linked with an AC outlet). The system remote also controls DENON CD players and tuners.
