Wat is dat voor ding?

[mga1600]

Rechts in de kofferruimte van mijn C70 Cabrio zit (achter de bekleding) een soort met rubber bekleed blok van een cm of 10 lang. 7 cm hoog en 3 cm dik. Het zit met rubberstrips vast in een behoorlijk zwaar uitgevoerd stalen frame. Ik zie geen enkele electische verbinding o.i.d. en vraag me af wat het is. Iemand een idee?

Is het nummer 14 ?
Zo ja dat is dan de 2de antenne van het Diversity systeem.

System overview
General

Note! The components included in the audio system depend on the market and on the equipment level specified by the customer.
-Radio (1)
-Dolby unit (2)
-Six-disc CD changer (3)
-Amplifier (4)
-Power antenna (5)
-Bass speaker (6)
-Treble speaker (7)
-Mid-range speaker ( 8 )
-Bass speaker (9)
-Centre speaker (10)
-Treble speaker (11)
-Balance filter (for door speakers) (12)
-Sub-antenna in bumper (13)
-Signal booster (for sub-antenna) (14)

Wiring
The wiring for all audio system components is preinstalled and integrated in the ordinary wiring harnesses

Radios
The radios are of the 'wide front' type and are available in two main versions:

-a single-disc CD player (SC-805, 816 or 836 depending on market)
-a CD player with a 3-disc magazine (SC-900 or 930 depending on market)

Amplifier
The amplifier is mounted on a bracket in the boot.
The amplifier is available in two versions:

-4*60 W (to match SC-8XX)
-4*100 W (to match SC-9XX)

Antennas
The C70 is provided with two antennas as standard equipment, a main (power-operated ) antenna and a sub-antenna. The sub-antenna is mounted in the rear bumper on the right-hand side and is provided with a signal booster mounted in the boot under the right-hand rear light.
On cars with RTI, the sub-antenna is used by the TMC/FM receiver for RTI. The sub-antenna has no function in cars without RTI and with an SC-8XX radio. Both antennas are connected to the radio in cars without RTI and with an SC-9XX radio.
The SC-9XX radio features a diversity (two-antenna) system. The radio signal reaching the receiver is passed through a multipath detector which modulates it to an intermediate frequency. The detector senses if the signal is affected by interference and, if reception with the main antenna is poor, transmits a control signal instructing the system to switch to the sub-antenna. This enables the radio to deal more efficiently with multipath interference.

Loudspeakers
1" treble speaker in dashboard
8" bass speaker and 4" mid-range speaker in each door The signal to the speakers is balanced by means of a balance filter mounted in the door.
8" bass speaker and 1" treble speaker in parcel shelf.

Centre speaker and Dolby unit (Dolby ProLogic Surround Sound system)
Only the SC-9XX radio is suitable for this system. Note! Cannot be combined with RTI. The centre speaker unit consists of a 4" bass speaker and a 1" treble speaker.
The Dolby unit divides the normal stereo sound into several channels (this function is described in further detail on page 18 ).

Six-disc CD changer
Standard/option/accessory depending on market.
The CD changer is mounted in the boot on the same bracket as the amplifier.

SC-900/930
Overview


A wide-front radio with large, ergonomically designed controls for simple, traffic-safe operation.
An external amplifier is required; the radio is equipped only with an amplifier for a centre loudspeaker (25 W).
The SC-930 is used in Japan (the radio does not provide RDS; Japanese traffic information is broadcast on two separate AM frequencies). The SC-900 is used in other markets.

Dolby ProLogic Surround Sound
Features
The car must be equipped with a centre loudspeaker and a Dolby unit.
The system is active only when the cassette player or CD player (not the radio) is playing.
The Dolby unit divides the normal left and right stereo channels into left, centre and right. The rear speakers also provide ambient surround sound, which simulates the resonance heard in the sound studio. In most modern recordings, the vocalist/soloist is heard in the very front, while the orchestra is heard from all directions, from left and right as well as rear. Dolby ProLogic Surround Sound provides a sound experience which is close to reality (that is, to the recording situation).
Operation of system
Press 'MODE' button to select function. The selection is displayed in the window. Dolby ProLogic 3 CH: Centre speaker active without ambient surround sound Dolby ProLogic 5 CH: Centre speaker active with ambient surround sound.
The volume of the ambient surround sound from the rear speakers can be regulated when the 'BASS' button is pulled out.
The volume of the ambient surround sound from the centre speaker can be regulated when the 'FADER' button is pulled out.

Note! Special attention should be paid to functions shown in bold when replacing the radio.

Bedankt voor het uitgebreide antwoord maar wat ik bedoel is zeker niet de antenne versterker. Die zit verder naar achteren. Deze zit in de lengte richting van de auto gemonteerd een paar cm van de rechterzijkant en een cm of 30 van de achterzijde.
Het zal wel iets van een sensor zijn, maar het gekke is dat er geen draden aan zitten. Ander idee?

[sbv]

Maak anders even een foto en zet die hier neer. Stel anders ook je vraag even op www.volvo850forum.nl

[Lambert]

ik mis in dit overzicht de subwoofers...(en eventuele versterker)

[heerhugo]

Dit plaatje is afkomstig van een Coupé.
Is dat wat jij bedoelt wit ? en zit er op de bovenkant een soort rode laag ?

[mga1600]

Dit is het ding wat ik bedoel. Enig idee? Ben benieuwd]

[sbv]

heb je misschien een wat grotere foto een waar wat meer van de omgeving te zien is ?

[mga1600]

Deze beter?

[sbv]

Je zou bijna zeggen dat het er later ingezet is. Zeker omdat er geen draden niets heen gaan.
Ik kan het niet thuis brengen

[hadico]

Er staat me iets bij van een trillingsdemper op die plek, kan er echter bij vnl niets over terugvinden.

[mga1600]

Bedankt voor jullie bijdragen in de poging dit raadseltje op te lossen.
Ik hou het maar op een trillingsdemper, iets anders kan ik er ook niet van maken. Belangrijk is het niet, maar ik kwam dit onderdeel toevallig tegen toen ik de bekleding daar loshaalde om een antenne versterker te installeren.

Big brother is watching you..?? Maar wie is dan de BB?

[Turbo Will-I-Am]

Good question!

[Turbo Will-I-Am]

Good question!

[MarioC70]

In m,n VW zit ook zo,n soort ding!
Met een boekwerk erbij van een of andere verzekering!

[waver]

Mogelijk een extra demper omdat het een cabrio is? Of iets voor de stijfheid van het chassis? Zit er maar 1? of ook 1 aan de andere kant?
