Review on 🔊 Enhance Sound Performance with Leviton 41920-A01 Mixing Audio Amplifier by Chris Hanson

Class D amplifiers have revolutionized most audio amplification applications. They are many times smaller and lighter than traditional Class A and AB audio amplifiers, and their efficiency exceeds 90%. My bass amp, for example, is about the size and weight of a bound book and puts out almost 300 watts of power while barely heating up. With a range of ASICs, they're easy to implement, cheap, and found in almost every consumer audio device. You can also buy individual units for around ten dollars or more, depending on the configuration. I have a 20-watt Lepai stereo amp with multiple inputs, tone controls, and Bluetooth that costs me about forty dollars in my basement, where I use it along with a pair of shop-bought Dynaco speakers for my shop music system. I can stream music from my phone or the network while I work, and the entire setup costs me less than seventy-five dollars. This amp in question costs a bit more but is designed for very specific applications. Leviton is a well-known name for specialized public address systems for institutions such as public address systems, school public address systems and the like. (In my early college years, I worked as an electronics technician at my school, installing and maintaining a lot of Leviton equipment.) Therefore, this module is designed to be built into a dedicated system, hidden in a lectern or audio cabinet is. In addition to the regular stereo RCA inputs, there's a low-impedance microphone input (with 48V phantom power available), just what you need for a lecture or paging system. There are tone controls, but they are meant to be adjusted and left alone. There is also the option of wireless IR control, which is very useful in an embedded system. Yes, it's a bit more expensive compared to cheap Lepai, topping and the like, but it's meant for a very specific use. As for my review unit, I originally set it up to connect external speakers to a medium-sized flat-screen TV. and it works fine in this application. However, this is overkill, so it may find another use.
