THE DESIGN
The design is shaped on its function, with special care to hide every point of
connection, from the smallest screw, to the controls and the cable plugs; on
every single element that makes up the amplifier in its deepest essence, giving
the products a sleek, sophisticated line while ensuring a clean, secure and
enjoyable installation.
THE SOUND
Analogue signal processors used in strategic points of the amplification stage,
contribute to the uniqueness of sound and timbre of Mosconi AS
series.
The audio power stages and the DC/DC converter use exclusively AUTOMOTIVE
MOSfet devices and provide high power supply coupled with high speed transient
response.
The pre amplifier circuitry has very low noise to eliminate hiss. The amplifier
also has time delay turn on mute to prevent transient thumps. These are
standard in the Mosconi design.
THE STRENGTH
Mosconi AS
series represents MOS commitment to the realization of amplifiers designed for
the sound as well as for competitions and SPL
The highest power, the high current and the impressive dynamics are the
features of a project studied with attention to even the smallest details.
The use of dedicated semiconductors, the distribution of power among parallel
transformers and the adoption of a highly efficient system of heat dissipation
provide all the strength, quality, versatility, control and reliability needed
to drive loads down to 1 Ohm Stereo or 2 Ohm mono BTL.
THE PROJECT
The quality of the project Mosconi
AS series amplifiers, combines
the highest criteria of design and efficiency.
An accurate internal and external engineering provides great power, small size
and high sound quality. The utmost attention has been paid to the realization
of the amplifier, especially in the disposal of heat, the air flow circulation
and the positioning of components.
Every detail has been designed and built to perform their functions well.
The heat-sink with its high efficiency is the result of meticulous planning
which has allowed the creation of a very compact form which is also highly
efficient from a thermal point of view.
The use of large amounts of aluminium (7Kg/MT) and the forced air cooling,
coupled with the dynamic controller fan ProSpeed®, ensure top performance.
The wiring is secured by massive power connectors derived from solid blocks of
metal, specially designed to handle the highest current demands. The power
connectors can accommodate cables up to 0 AWG.
The PC board is of professional manufacturing being double-side layer with
plated holes, made exclusively with the finest materials.
In higher performing products such as AS300.2 and the AS200.4, portions of
multilayer printed circuit board are used to ensure the least resistance to the
passage of the large currents involved.
A circuit called S.V.S. (Service Voltage Stabilizer) ensures the optimal
functioning of all services in both amplifier and DC/DC converter, physically
separating the performances of inside circuits from battery voltage
fluctuation.
Even in the design of the DC/DC converter, an advanced technology has been used
for the elimination of electromagnetic interference, whose production and
dissemination are also dramatically reduced in the electrical system of the
car, thanks to it.
THE CONTROL
Each type of adjustment is easily accessible from the top side of the
amplifier, which makes it very installation and setup friendly.
Every single control is specifically positioned in a functional way, making the
calibration simple and intuitive.
The functions in the crossover section of Mosconi
AS series can cover a great
variety of needs implementing a low-pass filter and a high-pass filter with the
ability to connect the two filters cascaded to achieve a band-pass.
Each amplifier has been equipped with an expansion "slot", to enable
future upgrades to the amplifier. One of these, the remote volume control (RTC
CARD), is already available.
THE RELIABILITY
There are numerous proprietary protections included to make the reliability of
the Mosconi AS series amplifiers at the highest levels and avoid possible
damages due to improper installations.
Protections by:
* Low current battery
* High frequency oscillation
* Bump while turning on
* Voltage on the chassis
* Voltage on the RCA
* Power outputs shorted to RCA
* Power outputs shorted to car chassis
* Output overload
* DC current through speakers
* Voltage difference between the grounds
* Excessive operating temperature
