The quality of the project Recital Audio DELTA 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 air cooling, 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 2 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 DELTA 4 and the DELTA 6, 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.
