DENON PMA-720AE

Denon Singapore

GENERAL FEATURES


Advanced High Current (AHC) Single-Push-Pull Circuit for musical detail and power
The PMA-720AE incorporates AHC transistors with 2 to 3 times the electrical current supply capability of conventional power transistors for audio. Denon’s acclaimed AHC Single-Push-Pull Circuit has been inherited from its high-end models which, together with a fully discrete amplifier design, produces a powerful sound field with beautiful musical details

High-speed, high-capacity power supply circuit for AHC Single-Push-Pull
The PMA-720AE’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 AHC Single-PushPull Circuit.

Wide dynamic range, supporting high-grade audio sources
The PMA-720AE’s tone control and power amplifi er 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-720AE plenty of latitude to handle the wide dynamic range of high-grade audio sources such as BD, Super Audio CD and DVD-Audio.

Main transformer with separate power supplies for audio and control circuits
The main power transformer has separate coiled wires for the audio and control circuits. The separate power supplies and divided circuitry layout work together to eliminate mutual interference and thoroughly preserve sound quality. Micro-processor stop mode, for higher sound quality.

The Micro-processor
Stop Mode automatically stops all operations of the microprocessor when it is not needed during playback. By stopping the oscillation of the microprocessor’s clock during normal listening, the audio signal is protected from noise and the quality of sound is improved.

Newly-designed remote unit
The PMA-720AE’s system 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 Network Player.

PRE OUT jack, for future upgrades
The PMA-720AE is equipped with a PRE OUT jack that allows the connection of a high-output power amplifier or subwoofer in future system upgrades.
