DE NON ASIA CO., LTD. 501 OCEAN CENTRE, HARBOUR CITY, CANTON ROAD,TSIIM SHATSUI, KOWLOON, HONG KONG DENON ELECTRONICS SINGAPORE PTE LTD. 257 SELEGIE ROAD #01-257 SELEGIE COMPLEX, SINGAPORE 188350 DENON, LTD. 3-16-11 YUSHIMA BUNKYO-KU,TOKYO 113-0034 JAPAN 32350302 DENON AVC-A1SR A/V Surround Amplifier DVD-A1 DVD Audio/Video Player AVC-AISR THX Ultra2 Certified A/V Surround Amplifier it The AVC-A1SR surround amplifier inherits the critically acclaimed amplifier design characteristics of the AVC-A1SR while adding Denon's much improved DDSC-Digital sound processor for greater diversity in multi-channel reproduction of digital and analog signals. The AVC-A1SR's objective is to bring out the maximum performance potential of all types of sound sources. This model also provides a video conversion function for greater monitor connection flexibility, the added convenience of variable subwoofer cross-over switching, that will ensure a listening environment that is as close to ideal as possible. With its support of THX Ultra2 and a wealth of other features, the AVC-A1SR has become Denon's latest “Surround Reference” AA/ amplifier for serious home theater enthusiasts. ■ THX Ultra2 Certified 7-channel High Power Amplifier The AVC-A1SR features an equal power 7-channel amplifier section, with identical amplifier design on all 7 channels. The Front (L/R), Center, and Surround (L/R) channels are driven by 225 watts of power each, and the two Surround Back channels, used for 6.1-channel DTS-ES and DOLBY DIGITAL EX sources, are also each powered with 225 watts (all channels rated into 6 ohms). High current, low impedance drive-capable discrete power transistors are used for each channel, and the high power output of 225 watts per channel (into 6 ohms) ensures that the speakers are driven with ample foundation to reproduce movie and music soundtracks with superb fidelity and the widest dynamic range. The AVC-A1SR proudly bears the THX Ultra2 logo, certifying that it satisfies the newest certification standards of Lucasfilm Ltd., governing performance, features, sound quality, power, stability into low-impedance speaker loads, and ease of operation. ■ Accurate Signal Transmission from the Pre-amplifier Section Parts suitable for high attenuation have been strictly selected for use in the volume circuit that controls the signal levels of all eight channels. Since a differential D/A configuration has also been adopted for each channel, the widest possible dynamic range is secured with mutual interference effectively suppressed across the entire frequency range. The pre-amp's gain is varied to match the output level, improving S/N in the range where the volume is often used. Highly accurate volume adjustment in variable steps of 0.5 dB in the range of -80 to +18 dB is possible as well. + > Differential Signal Input -> Output ■ High-quality Pure Audio Chassis Construction By positioning the power transformer at the center of the unit, the AVC-A1SR is equipped with a chassis construction in which unwanted vibrations are suppressed and excess vented heat is minimized. The digital circuits have been placed in the lower center of the unit and are completely shielded in their own enclosure, and the power amp circuits are located on the left and right sides. In addition, the analog circuitry has been isolated from the video circuitry to completely eliminate any mutual interference. The total chassis design preserves the purity of the audio signal from input to output to give your home theater a clean yet powerful sound, alive with all the details of the original recording. ■ Wide-Range Play Capability for DVD-Audio or SACD ■ New DDSC-Digital Processor, for High-quality Sound Reproduction 1. 24-bit, 192-kHz Analog-to-Digital Conversion The AVC-A1SR is capable of 24-bit, 96-kHz or 192-kHz A/D conversion, improving S/N and dynamic range by approximately 10 dB. A/D conversion and DSP processing (*1) of external input signals (max. 8 channels) is also possible. The AVC-A1SR is thus able to perform bass management and delay processing on DVD-Audio signals. THX post processing is also possible with this DSP. (*1) It is possible to select whether signals are to be...
