How Dr. AMP works?

Dr. AMP is a value priced digital amplifier that uses the latest PWM (Pulse Width Modulation) amplifier

technology. This mini amp takes input from a regular MP3 Player, CD player, MD player, Sound Card,

and any audio system. Once the signal is converted to digital pulse, it's amplified using the PWM

amplifier inside, and the output signal for the speakers is produced. The advantages of PWM amplifiers

compared to the traditional linear amplifiers are: efficiency close to 90%, high efficiency translates to

lower internal power loss, no heat sink space, and reduced overall physical size. Dr. AMP is suitable for

monitoring, playing games, music and any kind of audio source at the quality of professional audio

systems.

Selectable OPAMP-based preamp (OPAMP sold separately)

DR. AMP features a socketed OPAMP which enables the user to replace it with a different OPAMP of

choice for a variety of output characters. Dr. AMP is compatible with most speakers for general audio,

HiFi and A/V systems. By adding and changing diverse OPAMPs, Dr. AMP will be the multi-faced

universal preamp.
