User manual DENON POA-6600 schematic

[. . . ] The POA-6600 meets Lucasfilm's stringent THX Ultra certification requirements, and provides 120 watts of power per channel, RMS into 8 ohms, and 200 watts of power per channel, RMS into 4 ohms. s THX Ultra Certified Lucasfilm's stringent THX Ultra certification for power amplifiers includes dozens of tests and specification requirements, all to ensure accurate reproduction of motion picture soundtracks and musical performances. All aspects of power amplifier performance are thoroughly verified, to ensure inaudible noise, wide dynamic range, extended frequency response with accurate spectral response, and the ability to drive any modern loudspeaker regardless of impedance or efficiency. [. . . ] Dual Monaural Configuration Unlike conventional stereo power amplifiers, which rely upon a shared power supply for both amp channels, the POA-6600 features Denon's perfect Dual Monaural Configuration, with a separate high current power transformer and DC storage supply section for each amplifier channel. This provides the widest dynamic range, along with tremendous reserve capacity, compared to conventional stereo amplifiers. Stabilized DC Characteristics The use of a FET for difference input of one package type with superior direct current (DC) temperature characteristics and the ability to fine-adjust each channel individually have realized a high precision of 1 mV or less (standard value) in the output DC voltage of the POA-6600. This highprecision voltage is approximately one tenth that of conventional models and is the main reason these models are able to reproduce low-level signals with such exceptional fidelity. A-B Speaker switching for each channel One or two pairs of speakers can be connected to the POA-6600, and each pair can be activated or deactivated via front panel A-B speaker switching. Both pairs can be driven at once, if desired. Strictly Selected Parts for High Sound Quality A large number of high-performance parts, such as the electrolytic capacitor customized for high sound quality, OFC wiring material, film capacitor and resistors, have all been subject to stringent listening tests during their selection process to ensure unfettered, high-grade sound reproduction. s s Remote Power ON/OFF Rear panel mounted remote power on/off terminals are provided, for connection to Denon components such as the AVR-4800, for one-button power turn-on and turn-off convenience. 0. 1 ohms (1 kHz) Signal-to-noise ratio . . . . . . . . . . . . . . . . . . . . 110 dB (IHF, A-weighting) Speaker. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
