Rockville RPA70WBT 1000w 2-Ch Bluetooth Karaoke Amplifier/Mixer+Wireless Mics. The RPA70WBT is loaded with 1,000 watts of power! The built in amplifier is louder than similar products on the market that are rated at 3000 watts. When manufacturing this item we upgraded the power of the amplifier. We tested these against similar items on the market and these significantly outperformed the others rated at 2000 and 3000 watts. We do not exaggerate power ratings the way other brands on the market do. This is more than an amplifier. The RPA70WBT will be the control center for your home, karaoke, or professional audio system. You can hook up (3) additional power amplifiers to the system and add more speakers. You will be able to control the gain of each amplifier individually through this receiver. You can also connect 2 microphones directly to the receiver, an audio source (mp3 player, iPod, etc), and 2 video sources, and a recorder. This model is upgraded with a USB input so you can connect an iPod, portable hard drive, thumb drive, or other storage based device. There is a built in mic mixer with echo control, which makes this perfect for karaoke performances. This model has a built in VHL module and includes (2) wireless microphones. Connect your favorite device, and quickly start a karaoke party with your favorite songs! The remote control that is included will allow you to access all functions of the receiver quickly and efficiently. Another major advantage this model has is that it has a built in radio. This makes it perfect for home use, and the radio is also great for intermissions during live performances. The adjustable equalizer will allow you to fine tune your music so it sounds at its best. Built In Dual Cooling Fan. The built in fans keep the amp cool. This amp will never overheat on you like the cheaper ones out there. We actually upgraded this to a dual cooling fan when we were engineering these. Since we upgraded the amplifier we actually felt the need to also upgrade the fan of this unit to ensure it doesn’t overheat. Beautiful Multi Colored Display. The multi colored display is easy to read. It has an active EQ curve that goes to the beat of the music. The display is very user friendly. This model has a built in wireless VHF mic module and includes (2) wireless VHF microphones.
