Technical Pro MA2020 Class-T Stereo Mini Amplifier with Power Supply, Headphone Output & Microphone, Silver Lowest new price: $29.22
List price: $29.22
Brand: Technical Pro
Model: MA2020

Whoever said good things don't come in small packages never met the MA2020 Mini Amp. The MA2020 is designed to be used with smart phones, computer systems / laptops and traditional entertainment setups, or even a PA system that needs a little extra juice. On the back you can find a RCA line input and an MP3 (3.5mm) input, plus a RCA line output and bare wire speaker outputs to 2 speakers, making it easy to connect to just about anything. All of the controls you need are easy to spot and well placed for quick access. The power switch and volume controls are incorporated into one simple glowing rotary dial, so you can switch it on and adjust the volume at the same time, without having to go fumbling around looking for a tiny power button. If you prefer a totally dark room when listening, the LED light can easily be turned off as well. We have also included a standard 3.5mm headphone jack into the MA2020. Because not all music requires the same tuning and two people listening to the same song might want it to sound differently, you need total control. Some prefer more bass, while others prefer to really highlight those mid and high range sounds. To make everybody happy, there are treble and bass rotary dials on the front as well as a direct/EQ button giving you the choice to allow the sound to pass through unfiltered. Now you can customize the listening experience to your preferences. Other notable features include a 1/4 " microphone input jack and the ability to be daisy chained with multiple units.
