Acesonic AM-450 800W Power Mixing AmplifierAcesonic AM-450 800W Power Mixing Amplifier 4-Channel Click to expand $599.00 $399.00  


The Acesonic AM-450 Power Mixing Amplifier delivers a solid 800 watts of power coming through four separate channels. Karaoke singers will enjoy delivering a nice performance with powerful audio quality to really start the party! Sound goes through a 24-bit high performance digital signal processor where you can take advantage of some mixing functions such as reverb, echo, and a feedback eliminator. The three microphone inputs on the front panel can all have their volumes adjusted independently from each other and independently from the music level allowing you to fine tune singers and music together.

In addition to handling all your karaoke needs, this unit can be used as the main receiver in your home audio system. With four channels, you can fill your entire room with sound nicely. Connect up to 4 audio/video sources to the rear panel for quick access. If you're looking for bass, a 3-pin subwoofer output is located on the rear for you to connect a powered subwoofer to your system.
