This headphones amplifier circuit can deliver up to 1W on a 8Ω headsets. A stereo headset is connected, in generally, to an amplifier output through a voltage divider. This simple solving solution has 2 disavantages: the sound intesity cannot be adjusted independently from the speakers and the voltage divider lowers the attenuation factor for the headset which translates in bass altering. continue reading…

QX2-480 2 channel car amplifier is elegantly appointed with chrome end caps, but functionality has not been overlooked, as evidenced by the abundance of thermal dispelling aluminum and air circulating channels on both sides of the heat sink. All this, along with our proprietary power supply design for extreme bass reproduction, keeps the air moving and the mirrors vibrating in your vehicle. continue reading…

Pioneer Premier PRS-D1200SPL car amplifier features huge power delivered with low heat and distortion, thanks to its Class D technology. It provides Bass Boost, a subsonic filter, and a variable crossover, and it’s 1-ohm mono stable. Plus, you can externally bridge 2 amps together, increasing power and still keeping things simple to operate. continue reading…

The NAD M25 7 channel audio amplifier is actually made up of seven individual mono block amplifiers with each channel using a balanced junction FET input stage to eliminate cross-talk, resulting in exceptionally low levels of noise and distortion. Additionally, NAD employs a unique electronic ground isolation circuit to prevent ground loop noise in the system-a common problem with many complex multi-channel systems.
