The Phonic Sound Ambassador 75 is an Active PA Speaker with a built-in 4 channel mixer. 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.
