Description
The Quad-7850 is the smallest and powerful amplifier solution for your car computer project. This beautiful 4 channel amplifier delivers 4 x 50 Watts of high quality audio. Measuring only 70 x 65 x 30 mm the new TDA7850 internal amplifier can be installed inside the Black Box Nano or BBX-1 double din enclosures saving space, time and the need of power and audio extensions running through out your car. The Quad-7850 is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio. The fully complementary P-Channel/NChannel output structure allows a rail to rail output voltage swing which, combined with high output current and minimized saturation losses sets new power references in the car-radio field, with unparalleled distortion performances. The TDA7850 integrates a DC offset detector. This easy to use DIY amplifier kit provides a solid solution to the carputing audio needs. Powerful enough to power 4x50w or 2x100 W speakers this unit allows you to amplify your carputer audio to the vehicle’s OEM speakers without the need of expensive external amplifiers and running long audio and power lines throughout your vehicle.
