News from the DVD world [Pioneer: New VSX-AX5Ai with Advanced MCACC06.08.2004 (CR)
Careful and considered model care instead of hurtiger complete model change - in the principle already used with the
VSA-AX10Ai-S Pioneer trusts also with starting from October available VSX-AX5Ai as a successor of the VSX-AX5i. How also with the predecessor it acts itself around a THX SELECT-CERTIFIED 7-Kanal AV aV-Receiver with l.link terminals, which has now however Advanced MCACC (more to it at the end of the text). As is the case for the "large brother" it gives also here a sound Tuning of the renowned Air Studios/London. Videolaterally the receiver with the integrated video converter, like in the meantime straight with more expensive AV aV-Receivern usually, offers the possibility, of up-improving video material of smaller quality. With a noncommittal price recommendation of 1.999, - - EUR the "new one" 200, - - EUR is more expensive than the forerunner.
The substantial functions & product characteristics:
7-Kanal Advanced Direct Energy MOSFET - for most efficient, high performance and stable sound quality with 7x100 Watt.
Advanced digitally processing - support of all usual Surround Tonformate, including Dolby ProLogic IIx, DTS 96/24, DTS IT, DTS NEO:6 and THX Surround ex
Digital i.LINK audio interface - the digital signal transmission of all usual compressed and unkomprimierten formats including DVD audio and SACD supports. With PQLS (Precision Quartz LOCK system) the original-faithful klangwiedergabe is ensured with the similar signal output.
The improved structure offers shortened signal paths and separate circuits, in order to minimize and obtain around a still more precise sound signal disturbances.
TAOC of absorber feet and power pack stabilizer increase the stability of the chassis and reduce in such a way vibrations, which can affect the klangbild negatively.

High-quality: The remote maintenance
Owing to i.link also highly soluble digital data can be received and processed from DVD audio or SACD signal sources digitally

- adaptive LCD remote maintenance with macro functions
Over Advanced MCACC - Advanced Multi Channel Acoustic Calibration system
The new, further developed 3-D calibration method of the Advanced MCACC considers the response effects in the area and makes thereby still a precise measurement possible. Direct and indirect sound portions are calibrated simultaneous. Advanced MCACC carries out - according to Pioneer as the first system - the calibration with emphasis on the harmonious total illustration and obtains thereby a repeated improvement.
Comparison of both pion he systems
MCACC - Parameter of the calibration:
Analysis of the attached loudspeakers
Analysis of the loudspeaker size
Attitude of the deceleration time
Level attitude of the loudspeaker systems
Automatic Entzerrung of the loudspeaker systems
Advanced MCACC - additional parameters of the calibration:
3-D calibration with analysis of the timings
Expenditure of the response characteristic on the PC
Automatic correction in relation to the room size
Advanced MCACC:
Due by obstacles in the hearing area or to the spatial acoustics if the frequency response of an indirect yields, reflected signal from the direct signal. The brain of humans analyzes and confirms the sound information much rather on basis of the direct and indirect sound, which results from the klangliche balance, the position of each loudspeaker and the sound field produced together by all loudspeakers.
Fact 1: The human hearing can differentiate between direct and indirect sound.
Fact 2:Das human brain analyzes and evaluates the noticed sound
and its tonal balance rather with the elements of the direct sound.
Fact 3: A core element with the perception of a three-dimensional sound stage
is the stable position of an acoustic source.
Standard MCACC corrects the tonal balance of direct and indirect sound. Acoustically "alive" areas with long reverberation times cannot be calibrated correct however. Here the comparison of both systems:
Standard MCACC = 2-D calibration
(frequency response and level)
Advanced MCACC = 3-D calibration
(frequency response and level + timing)
Advantages of Advanced MCACC:
Clear detection of the acoustic sources
Rendition of all details & nuances
Natural & spatial rendition
