Class D amplifier superior to the Class AB ones in efficiency and performance. Efficiency - The Soundigital Class D amplifiers have a total efficiency (power source + output) higher than 70%, assuring a battery consumption and a heating lower than the expected.
Make sure the cables are properly secured throughout the installation; Wear gloves, safety glasses and and all necessary PPE during the installation of SounDigital amplifiers. THIS "WARNING" SIGN ALERTS THE USER OF IMPORTANT INFO. NOT FOLLOWING THIS INSTRUCTIONS MAY CAUSE INJURIES TO THE USER OR DAMAGE TO THE EQUIPMENT.
ASSEMBLING AND DISASSEMBLING THE PLASTIC COVER The plastic covers have the function of finishing and hiding the amplifier fixing screws. To disassembling and assembling them, follow the instructions below. DISASSEMBLING OF THE PLASTIC COVER 1. Carefully pull out the top of plastic cover to release the upside latches, as shown in the picture 1. 2.
ELECTRICAL DIMENSIONING AND AUDIO INPUTS ELECTRICAL DIMENSIONING For proper operation of your SounDigital amplifier, you need the proper dimensioning of the electrical system and the cables used. The table below shows the minimum section of GND cables, +12VDC cables and speaker output cables according to the power generated by the amplifier.
INSTALLATION SEQUENCE Warning! Mount the amplifier in such a way you have access to the connectors; Ø Install the power cables in the vehicle properly, starting from the battery to the fuse Ø holder or circuit breaker, use the cable with the appropriate size. Make all connections, install fuse holders or circuit breakers, but without placing the fuses or with the circuit breakers in the "Off"...
CROSSOVER SET UP How to Adjust the Crossovers Set in the variable control "HIGH" between 5 Hz and 80 Hz ("A") where you want to perform the high pass cut filter; -3dB -15dB ƒ ƒ High High Pass Pass Set in the variable control "LOW" between 50 Hz and 20 kHz ("B") where you want to perform the low pass cut filter;...
USING THE BASS BOOST Using Bass Boost The Amplifier Bass Boost setting enables the user to boost the sound intensity at low frequencies of the sound system, where boost intensity can be adjusted. This is a semi-parametric equalizer type circuit with ''Q'' value for the fixed filter, with an intensity boost adjustment from 0 to + 12dB (16 times), and a central frequency adjustment of the filter in 50Hz, making it versatile for several types of sound systems.
