The Sound Ambassador 120 is an active PA Speaker with a built-in 4 channel mixer boasting a 120 Watt power amplifier. The unit can be further customized to include two wireless UHF microphones. Other important features include XLR microphone inputs on channels 1 and 2, line input channels with 1/4" and XLR or RCA inputs - all with individual volume controls. A Link Out connector with a 1/4" phone jack and XLR jack enables two Sound Ambassadors to be linked together to further enhance your set up. Additional speakers can also be added to share the power from the amplifier through the Speaker Out jack. Channels 1 through 3 are topped off with 2-band EQs, and the unit further features master volume control, a built-in limiter, and protection circuitry. The DC power inlet allows the Sound Ambassador to be used in conjunction with portable battery packs, ensuring you're always able to use it - even when an AC power source is unavailable. All of these features combine to make the Sound Ambassador 120 a must-have for touring bands, clubs and karaoke.
