User manual DENON PMA-560

[. . . ] Integrated amplifier with enhanced sound expression. The PMA-560 features High-Current Single-Push-Pull circuitry based on Denon's ideal for pure audio amplifiers that aims for both strength and detail in the musical sound being heard. [. . . ] Denon engineers have tapped their proven 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 PMA-560 includes the main functions that control Denon CD players. Features High quality sound · High Current (HC) Single-Push-Pull Circuit to balance musical detail and power · Wide dynamic range playback, supporting a high-grade audio sources · Main transformer with separate power supplies for analog and digital circuits · Microprocessor stop mode, for higher sound quality · Thoroughly vibration-resistant design with Direct Mechanical Ground Construction · European sound-tuned Others · Less than 0. 3 W at stand-by · Aluminium panel design, befitting the elegance of an audio component · Design matches the new DCD-510AE CD player Useful Functions · Newly-designed system remote unit · Phono Equalizer Amp (MM), for connecting an analog record player · Headphone jack High quality sound · High Current (HC) Single-Push-Pull Circuit to balance musical detail and power The PMA-560 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. · Signal Level Divided Construction The PMA-560 employs Denon's Signal Level Divided Construction (SLDC) in which the circuits for small and large signals, the microprocessor, and other circuits are separated in an ideal manner to minimize mutual interference. Main Specifications Power amplifier section Rated output 45 W + 45 W (8 ohms, 20 Hz - 20 kHz, THD 0. 07%) 70 W + 70 W (4 ohms, 1 kHz, THD 0. 7%) Total harmonic distortion 0. 02% (8ohms, 1 kHz) · "Source Direct" function, for clean pure audio playback (simple & straight signal) The PMA-560 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 input sources. Preamplifier section Phono equalizer rated output 150 mV (REC out terminal) Input sensitivity / Impedance Line 100 mV/47 kohms (Source Direct: OFF) 100 mV/16 kohms (Source Direct: ON) Phono 2. 5 mV/47 kohms RIAA deviation Phono 20 Hz - 20 kHz, ±0. 5 dB Signal-to-noise ratio (IHF A network) Line Phono (MM) Tone controls Bass Treble 100 Hz, ±8 dB 10 kHz, ±8 dB 105 dB (Source Direct: ON) 84 dB (input terminals shorted, input signal 5 mV) · High-speed, high-capacity power supply circuit for HC Single-Push-Pull The PMA-560'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.

[Tuner operations] - Preset channel call Other AC outlet x1 Out Recorder-1 (REC) Recorder-2 (REC) x1 x1 Ports In Phono (MM) CD x1 x1 x1 x1 x1 x1 · Main transformer with separate power supplies for analog and digital circuits The coiled wire of 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-560 also has a prepared transformer to minimize power consumption during remote power-off standby and improve environmentally friendly performance. Tuner Line Recorder-1 (Playback) Recorder-2 (Playback) · Microprocessor stop mode, for higher sound quality The Microprocessor 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. · Speakers A / B switches Others · Thoroughly vibration-resistant design with Direct Mechanical Ground Construction The power transformers, itself a source of vibration, has been placed near the ground and immediately above the insulators to allow direct release to the ground and thoroughly prevent the propagation of unwanted vibration or noise.
