Description stereo amplifier, Denon PMA-720AE

Amplifier Denon PMA-720AE has replaced the previous model PMA-710AE of the popular 700-th line components of the brand Denon.

This unit belongs to the middle class Hi-Fi, has effective anti-vibration metal chassis and has an amazing appearance. Fine tuned cute design aluminum front panel, where all the elements are in place, has always been a characteristic feature of the products of this company. The handle of the selector of inputs made in the right part, great volume control is set exactly in the center. In between are the selection buttons set of speakers (A and B). To the left is the power button, 6.3 mm headphone Jack, key, loudness and Source Direct, as well as the regulators of timbres and balance. In the new remote control that can command and several other devices Denon, special attention paid to good management and ergonomics.

Amplifier Denon PMA-720AE is equipped with high-current push-pull circuit using discrete components, providing excellent detail and the necessary power. Involved in the design of Schottky diodes. Output stages used in reliable, high quality transistors. The unit has an extended dynamic range, making it ready for playback of audio recorded in formats BD, DVD-Audio or SACD. It is possible to note the presence of high-capacity capacitors in the power supply and efficient operation of the supply transformer that has separate windings for audiocontrol and control circuits. The power output of the machine is 85 watts under load at 4 Ohms and 50 watts at 8 Ohms. Mode compensates for the lack of Loudness in the low frequencies when listening at a low volume level, and Source Direct disables tone, balance and loudness, freeing the signal from distortion.

There are six RCA line inputs, including connectors Phono stage that only works with MM cartridges. Outputs: for connecting recording devices (RCA), to output the signal from the preamp to a separate assistant. The back panel also has a grounding terminal for a turntable, the socket of the IR receiver and three additional network outlets. With four pairs of screw terminals you can connect two sets of speakers.

Stereo amplifier Denon PMA-720AE is configured in accordance with the European school of sound. His sound is different, transparent crystal clear high frequency-range, well-researched natural MIDs and sufficient bass.
