  • "Works like a charm. Nice form factor." by jgruessing68 on 11/3/2012

    I have used this to restore the audio in a vintage arcade cabinet. It cranks out plenty of raw power to drive the original speaker without distortion... it's important to properly ground everything... the front end is very sensitive. I would recommend for any project like this where long term reliability and varying operating conditions exist. It requires a cooling plate, but I have yet to drive it hard enough to get it above luke warm. Nice product.

  • "KEMO M034N Amplifier Module" by DrGizmoBB on 3/27/2012

    I purchased this single channel amplifier module to power a center channel speaker for a flat screen TV. The unit has 5 screw terminals that are quite small, but easy to use. The unit was screwed to a heat sink prior to use. The gain is quite high so installing a 10K volume control is recommended. I powered the unit with a 15V 4A switch mode power supply. The module is characterized as a "Bridge" amplifier, which actually consists of two separate internal amplifiers, one inverted, and one non-inverted. These outputs drive the speaker differentially, and is the reason for the 40W rating into 4 ohms. The sound quality is quite good, without hum or hiss. I could not imagine an easier product to use.
