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. 0. 002 % (60 Hz/7 kHz : 4/1 at rated output, 8 ohms) Frequency response . . . . . . . . . . . . . . . . . . . 1 Hz - 100 kHz +0, -3 dB (at 1 W) Input sensitivity . . . . . . . . . . . . . . . . . . . . . . . . . . . 110 dB (IHF, A-weighting) Speaker. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
