ASA Mercedes MOST>Cinch by ACV

Active system adapters serve to maintain factory-installed sound systems.

"This enables the connection of retrofit radios to a vehicle's own active system while retaining the OEM amplifier and the connected speakers by adapting, adjusting, or converting the output signals of the signal source to the signal input of the OEM amplifier."

Depending on the vehicle and the installed OEM active system, various functions such as fader or sound and subwoofer settings may be omitted.

Check for function before final assembly.

Frequent questions about ASA Mercedes MOST>Cinch

Welche Funktion erfüllt der ASA Mercedes MOST>Cinch Adapter?

The ASA Mercedes MOST>Cinch Adapter from ACV enables the integration of aftermarket radios into the factory active systems of specific Mercedes models. It ensures that OEM amplifiers and speakers can still be used by adapting the output signals of the new source to the requirements of the existing system. Signals from the MOST interface are converted to standardized RCA connections, allowing for a seamless transition between different audio systems. However, it is important to note that some functions such as the fader or subwoofer settings may not be supported.

Was ist bei der Installation des ASA Mercedes MOST>Cinch Adapters zu beachten?

Before starting the installation of the ASA Mercedes MOST>Cinch adapter, the system should be checked for functionality. The adapter requires connection to the OEM sound system MOST interface using a red and white cinch cable. For proper operation, the yellow wire must be connected to +12V constant power (terminal 30), the black to ground (terminal 31), and the red to +12V switched ignition power (terminal 15). Additionally, any OEM additional components such as CD changers or TV tuners that are in the MOST ring should be removed to avoid potential interference.

Welche Einschränkungen hat der Adapter hinsichtlich der Faderfunktion?

The ASA Mercedes MOST>Cinch adapter does not support a fader function. This is because the full functionality of the OEM system cannot be fully replicated when adapting the signals from the MOST interface to the Cinch output. Especially in vehicles with complex sound systems, this can lead to limitations in sound adjustability. For users who rely on the fader function, this means that other hardware or software solutions may need to be considered to meet this need.

Mit welchen Mercedes-Modellen ist der ASA Mercedes MOST>Cinch Adapter kompatibel?

The ASA Mercedes MOST>Cinch Adapter is particularly suitable for Mercedes models equipped with the Audio 50 APS Comand NTG2/NTG2.5 navigation systems. It is compatible with vehicles such as the Mercedes CLK-Class (A209/C209) from 04/2005 to 01/2010, the Mercedes CLS (C219) from 04/2008 to 09/2010, the Mercedes E-Class (W211/S211) from 02/2008 to 08/2009, and the Mercedes SLK-Class (R171) from 04/2008 to 03/2011. Models without the mentioned Comand systems or vehicles without the D2B Optical Bus System are not compatible.

Welche Verbindungen nutzt der ASA Mercedes MOST>Cinch Adapter?

The adapter uses a variety of electrical and optical connections. The primary interface consists of the MOST bus, a light-based communication standard in the automotive industry. The conversion takes place via RCA connectors, which are common in retrofit devices. Additionally, loose cables provide the power supply: Yellow for constant power at terminal 30, Black as ground at terminal 31, and Red for switched ignition power at terminal 15. This combination of optical fibers and electrical connections enables seamless integration into existing sound systems.

Muss der ASA Mercedes MOST>Cinch Adapter vor der Endmontage geprüft werden?

Yes, it is essential to check the ASA Mercedes MOST>Cinch adapter for functionality before the final installation in the vehicle. This ensures that all connections are correct and that the sound system operates properly. A preliminary check can avoid later troubleshooting and potential additional costs. Above all, attention should be paid to the correct signal transmission from the new audio source to the OEM amplifier. It should also be ensured that no additional OEM components, such as CD changers, cause interference if they have not been removed correctly.

Welche Komponenten müssen aus dem MOST-Ring beim Einbau entfernt werden?

When installing the ASA Mercedes MOST>Cinch adapter, some OEM additional components should be removed from the MOST ring to ensure the correct functioning of the adapter. These include CD changers, TV tuners, and telephone modules. Their removal is necessary as they can interfere with signal transmission in the MOST network. If these components remain in the system, it may lead to disturbances or poor signal transmission. The adapter should also be equipped with a fiber optic connector for the MOST ring (Item: 771000-2100) to complete the circuit.

Was sind die Anforderungen für den Anschluss der Stromversorgung des Adapters?

The power supply of the ASA Mercedes MOST>Cinch adapter requires special connections to function properly. This includes the yellow wire, which is connected to +12V constant power (terminal 30) to ensure a constant power supply. The black wire represents the ground connection at terminal 31, while the red wire is connected to +12V switched ignition power (terminal 15) as well as Amp Remote or Antenna Remote. This connection configuration allows the adapter to be activated only when the ignition is on, which is energy-efficient.

Warum ist die Faderfunktion beim ASA Mercedes MOST>Cinch Adapter nicht verfügbar?

The fader function is not available with the ASA Mercedes MOST>Cinch adapter because the adapter primarily focuses on the signal conversion from MOST to Cinch, without retaining full control over the individual audio channels. As a result, this functionality is sacrificed in favor of universal compatibility. In retrofitting configurations, the ability to shift the sound image between the front and rear speakers is therefore lost. For vehicle owners who prefer a uniform sound distribution throughout the interior, this could represent a significant limitation that requires alternative audio technologies.

Was ist die Bedeutung der Lichtwellenleiter in diesem System?

The optical fibers in the ASA Mercedes MOST>Cinch adapter play a crucial role as they form the basis of the MOST communication system. As a light-based transmission technology, they enable fast and low-loss signal transmission between the various audio components in the vehicle. The MOST bus uses these optical fibers to transmit audio signals between the head unit and the connected systems such as the OEM amplifier. When using the adapter, these connections must be closed using the optical fiber connector (Item: 771000-2100) and the optical fiber loop (Item: 771000-2101) to maintain the signal flow.

Alpine tube 12 bazooka , Un sacré caisson de basses ,

Un sacré caisson de basses , j'ai eu un 46 cm killer 454 de l'époque année 90 , qui tapait vraiment bien , mais ce tube est bien plus fort et plus ample, toutes les basses passent sans problème, avec une télécommande à réglage multiples taramps eq bass , et un ampli Machete de masori , le couple est parfait, personnellement j'en ai deux tubes et ça donne énormément, avec l'ampli 2 x 530 en 4 ohms . Parfois le plus simple est bien meilleur et plus durable .

X-10 v3 d2

Hallo. Sehr freundlicher Kundenservice und schnelle Auftragsabwicklung. Der Lautsprecher ist brandneu und unbenutzt. Ich habe ihn vor einiger Zeit gekauft, aber erst kürzlich das Gehäuse fertiggestellt. Die Parameter entsprechen den Herstellerangaben: 42,5 Liter Nettovolumen, abgestimmt auf 32 Hz und 21 mm starkes Sperrholz. Ich hatte noch nie einen 10-Zoll-Lautsprecher und wusste nicht, was mich erwartet, aber das Ergebnis hat meine kühnsten Erwartungen übertroffen. Der Bass aus einem so kleinen Lautsprecher in einem so kleinen Gehäuse ist einfach unglaublich. Um den X-10 zu kaufen, habe ich meinen DD 712f in einem 70-Liter-Gehäuse verkauft, und der war ein Volltreffer. Der Sundown ist in jeder Hinsicht besser. Ich kann diesen Lautsprecher und den Händler, bei dem ich ihn gekauft habe, wärmstens empfehlen. Beste Grüße.

Top Upgrade für Canton System

Ich habe den Woofer in meinem Skoda Octavia 3 mit Canton Soundsystem eingebaut.
Der Einbau war Plug & Play, alles passt perfekt ohne Anpassungen.
Im Vergleich zum originalen Canton Subwoofer spielt dieser deutlich stärker, präziser und mit mehr Druck.
Ich kann den Woofer jedem empfehlen, der mehr Bass aus dem Canton-System herausholen möchte – lohnt sich absolut!
