This PA Package includes a Yamaha EMX512SC 12-channel powered mixer, 2 Yamaha A12 12" 2-way loudspeakers and 2 Audio-Technica M400S Handheld Dynamic Microphones. To round out this bundle of live gear, you get 2 Musician's Gear All-Steel Tripod Speaker Stands, 2 Gear One XLR microphone cables, and 16-Gauge speaker cables. Yamaha EMX5125C 12-Channel Powered Mixer The durable, lightweight Yamaha EMX512SC 12-Channel Powered Mixer has dual 500W amps, 16 Yamaha SPX effects, built-in graphic EQs, and loads of input options. Flexible power The power mode switch lets you use the dual power channels as a stereo amplifier, or use one channel for the main speakers and one for the monitors, with separate monitor mix setup via the channel MONITOR controls. SPX digital effects 16 Yamaha SPX effects--including reverb, echo, chorus, flanger, phaser, and even distortion--let you add the finishing touches to your live presentation. Graphic EQs Graphic equalizers are provided for both the main and monitor power channels so you can effectively control feedback or tailor the sound to match the room and program material. Input options The EMX512SC offers a total of 12 input channels—4 for monaural microphone (with phantom power) or line input, plus 4 pairs that can function either as monaural mic inputs or stereo line inputs—providing a versatile mix of input capabilities for a wide range of applications. If only mic inputs are needed, you can use up to 8 mic channels. If you want to play recorded background music during breaks using a stereo input, and have a keyboard player with stereo outputs, you still have 6 mic/line inputs available. If all 4 stereo pairs are used to handle stereo line sources, you still have 4 channels available for mono mic or line input. It's a versatile system that can adapt to your needs with ease! Yamaha Speaker Processing Yamaha Speaker Processing (YSP) provides optimized matching with speakers, for clean, solid reproduction that will deliver your music with maximum impact. FCL (Feedback Channel Locator) system The Yamaha FCL (Feedback Channel Locating) system makes locating and eliminating feedback easier than ever. FCL indicators provided on each input channel indicate which channel feedback is occurring in, so you can identify it visually and adjust levels or EQ as required. Another handy features is a Standby switch that mutes channels 1 through 8 so that, for example, after rehearsal or between sets you can mute performer's inputs 1 through 8 without having to change fader settings, while stereo inputs 9 through 12 remain active for background music playback. Durable, lightweight design At only 22 pounds and equipped with conveniently located handles, the EMX512SC is easy to transport. It's built to withstand the rigors of the road and deliver reliable performance, night after night.

Audio-Technica M400S Handheld Dynamic Microphone The Audio-Technica M4000S Handheld dynamic microphone has professional features with a ridiculously affordable price tag. Its frequency response is tailored for crystal-clear vocal reproduction. Great feedback rejection and focused pick up are due to the unidirectional polar pattern.
