Description stereo amplifier, Denon PMA-1520AE

Integrated stereo amplifier Denon PMA-1520AE have undergone significant improvements compared with the previous version, and also received a new design of the front panel. Due to the simplified switching scheme the number of controls on it decreased due to the appearance of the unit became even more solid. The front panel of the amplifier, as before, is made from aluminum.

The device is made on the principle of full dual mono, with separate mains transformers, which provide good stereo separation. The transformers are placed in a copper shield that prevents interference to sensitive audiotape. In the power supply rectifiers used in high-speed Schottky diodes, and storage capacitors considerable capacity. Built output stages push-pull circuit extraocular field-effect transistors (UHC-MOS), providing good compatibility of the device with the most sophisticated sound systems.

Amplifier equipped with a high quality volume control with electric drive, provide smooth change of signal level with minimal noise and maintaining a balance of the channels. Denon PMA-1520AE has inputs for five line sources and output to connect analogue recording device. Among the advantages of this model can be called a built-in Phono equalizer of high class, is designed to connect both MM and MC-heads. To select the desired input sensitivity and other parameters of the circuit of the corrector on the rear panel there is the switch. In addition, Denon PMA-1520AE is the output from the preamplifier and direct input to the power amplifier, which significantly increases the flexibility of its use. To the amplifier you can connect two pairs of speaker systems, and its front panel has a connector for stereotipov.

All important from the point of view of the quality of the sound parts of the amplifier circuit set selected audiophile-grade components. The amplifier's chassis is made of materials having different resonance characteristics, thereby achieving good vibration resistance of the entire structure. Network transformers are mounted using a special damping pads.
