The car similar Mercedes S600, usually try "to pack" on a maximum. But audiosystems of such complexity a rarity even for «S600».
The idea was idle time: to construct in the machine « an ideal sound » carelessly on expenses, but considering that fact, that the owner of a magnificent sedan likes to go not only by a back sofa, but also at the wheel.
Subwoofer to each channel
To fitters there was a task in view to create system, at which as in complexes of house cinemas, the sound would be only the maximum standard. More precisely speaking, it was required to construct a volumetric picture of sounding in two zones of the car - forward or back on a choice.
To realize this complex technical project it was possible by means of the scheme with strengthening of each channel from components Rockford: the head device RAV-DVD1, five amplifiers and twenty four loudspeakers. Each channel thus has turned out high-grade from the point of view of reproduction of a frequency spectrum. Each channel has high-frequency, mid-frequency channels and support of a subwoofer. The surprising decision of the project - the "floating" front, which sources are if necessary displaced from a lobby in a back part of interior - depending on an arrangement of the "main" passenger. Thus in any variant sixteen loudspeakers simultaneously work.
So, if the boss of pleasure for the sake of villages for a rudder, the face-to-face signal reproduces the forward complete set of loudspeakers - two two-componental Rockford FNQ 3614 in corners of the forward panel and two subwoofers Rockford RFP 4408 in forward doors.
The back passenger carries out carry of a musical stage to a back part of interior pressing of one button located between back seats. However, to masters this simplicity was given hardly. To provide appropriate sounding the bottom spectrum of a sound range long it was not possible - while in cards of back doors have not placed the system similar face-to-face. It has provided a scale and deep sound in area of a back sofa.
The signal of the central channel for a forward part of interior is reproduced by the componential acoustic system Rockford RFP 4406 established under a windshield in the center of the panel. At carry of a zone of comfortable sounding back in work joins two: high-frequency and mid-frequency which are established in a forward armrest, - for its best effect it is necessary to translate preliminary in vertical position. The bass component of sounding is provided in that case with the six-inch subwoofer "laid" in the back console on a tunnel of a floor.
The rear acoustic system remains constant at any variants of accommodation of passengers. In a shelf under back glass two 6-inch subwoofers of series RFP 4406, supporting the rear channel, and two-componential EXPERT Rockford FNQ 3614 disappear.
For low frequencies in system 12-inch subwoofer Rockford RFD 2112 located behind a back of a back seat and "served" by separate amplifier Rockford 1000db "answers".
To everyone the volume
Following the concept of maintenance of faultless quality of sounding, experts have taken care of correct acoustic registration of all involved loudspeakers. Naturally, ideal variant would be to place any of loudspeakers in own volume. And it has been made, and despite of uniformity of the applied acoustic systems, for each case the volume paid off separately.
It has most difficultly appeared to place acoustics in the forward panel. Under the forward panel of "six-100-th" - the space filled by developed air lines, plaits of wires, weight of switches and servomechanisms, it was necessary to squeeze six loudspeakers with cases. Besides to recede from the place certain at calculations it was impossible on millimeter! To keep all regular communications and correctly to establish loudspeakers, masters of sound firm have bought the forward panel from similar body W140 and long experimented on it.
Place under loudspeakers in an armrest and the back console have found rather quickly. It was a little bit more complex to establish on three cases of face-to-face loudspeakers at back doors, and without that filled by own equipment. It was necessary to tinker and with configuration of acoustics under a back shelf. From the seven loudspeakers located there, it is outside visible only two high-frequency of structure two-componental rear EXPERT Rockford FNQ 3614. Average loudspeakers invisible to strangers and subwoofers cost more close to racks of a body, and for the main 12-inch subwoofer in the center have established the special two-chamber case. One of its volumes tight, and through a phase output is informed the second with interior. The given variant of acoustic registration of a source of low frequencies guarantees softness of sounding at any loudness.
Power compartment
Such quantity of the equipment and auxiliary devices could be located, perhaps, only in a luggage carrier of the car of an S-class. Four exclusive amplifiers Rockford X4 have strengthened on walls of a luggage compartment, and the fifth - Rockford 1000 db, intended for a subwoofer, have arranged under it.
As power consumption of an audio system reaches 2,7 kw, additional energy sources were required. Their role was executed with two alkaline accumulators Stinger 1000, established under a floor of a luggage carrier. In the same place have placed the block of electric distributing and three condensers Stinger in capacity 3 Faradas everyone. They are called to compensate short-term "failures" in circuits of a feed at peak loadings. For DVD-receiver Rockford RAV-DVD1 separate protection against similar troubles - in the form of the small buffer battery is stipulated.
At installation of acoustics it has been in total spent the order of 180 meters of cables Stinger, for communications it was required about 60 meters of posting. During connection of lines masters in order to prevent possible electromagnetic noise had to shift numerous regular plaits of the car repeatedly.
Local TV
At the second stage of the Championship of Ukraine on an auto sound this Mercedes S600 has won first place in a category "Multimedia" among fans. Its multimedia system includes three monitors: Audiovox PAV-9 it is established in the forward console, two Audiovox LCM 500NP - in forward headrests. Each "TV" can reproduce a signal of any of three sources - TV-tuner Audiovox SDB 45, 10-disk DVD-changer Challenger MVCH10 and the DVD-receiver. By the way, the block of the receiver have established behind an armrest of a back seat, and its obverse panel for convenience of using cut in the top part forward panel. It is possible to listen to the Soundtrack of any of pictures through individual headphones, and two pairs established behind - wireless.
The full control
For management sound-and videosystems of this "stuffed" sedan it would be required eight boards distance control, that, certainly, rather inconveniently. Soundmen send another by - have made one board, having programmed it on the control over all operated components. After receivers of signals distance control have disguised in the case of the fixture nearby central mirrors, there was an opportunity to concentrate all management of an electronic stuffing of "six-100-th" literally in one hand.
