QUATTROCENTO - FourChannel Amplifier

QUATTROCENTO

The QUATTROCENTO is a meticulously crafted 4-channel car audio amplifier, designed by Roberto Tognon for music enthusiasts who seek high-quality sound. Housed in a compact CNC-milled aluminum chassis, its sleek and understated design, paired with top-grade components, guarantees durability and exceptional audio performance.

Proper installation guarantees better performance, follow these suggestions for installation:

- Only use shielded cables to connect the audio signal between the car radio and the amplifier, it is not necessary to use very expensive cables, but do NOT use very bad cables!

- The use of good quality RCA connectors guarantees a good contact, lasting over time and reliable even after several operations of insertion and disarming.
- Shielded cables must be kept at a minimum distance of 10cm c.a. from any generators or fields of automotive electronics to avoid introduced noise from items such as power units, pumps, computers, other cables, etc....

- For power connections use only good cables, of suitable sections and protected in the engine compartment. The cables for car-audio applications are very flexible and therefore easy to install.
- Carefully take care of the laying of the cables and operate in order to follow different routes to signal cables from power cables.

- It is a good idea that the mass of the amplifiers is connected to the same point, together with the car radio's one.
Example: if there are two amplifiers in the trunk, find a good grounding point for the amplifiers themselves and bring the mass of the car radio to the same point using a cable ( 3-5mm). 
- Fix the amplifier securely, to avoid its movement and then the cables jostling.

- A well-designed and equipped system may involve the collection of various devices, if this happens, ensure adequate ventilation of the place where the amplifiers are installed, perhaps with the aid of an additional forced air flow by a fan inside the various compartments.

-This amplifier is designed to work only at on a 12V DC system from the car battery, and properly operating charging system.  Do not attempt to power it with AC or different voltages!
-Install the device on a flatm secure and solid way that does not affect driver's guidance, or allow the device to become airborne,
-Do not place the device in very hot places (such as the engine compartment).
-Make sure that the installation location is not subjected to high humidity and / or splashes of water.
-Perform solid and safe connections, using only cables of adequate section and type.  It is absolutely essential to install a fuse of adequate value near of the battery.  In the installation / removal and maintenance operations it is absolutely necessary to remove the fuse located near the battery.
-If the device is subjected to severe shocks that could visibly damage the chassis
let it be viewed by the service center or by a certified professional installer.
-Keep the device clean and do not obstruct normal chassis ventilation, and do not use aggressive detergents for cleaning.
-The maintenance's allowed to the end user, are to set input sensitivity, display setting and the replacement of the fuse with identical characteristics, (to be performed as described in the "Diagnostics" paragraph).
