This package contains a Yamaha EMX212S and a pair of A12 passive PA speakers. It comes with a pair of standard speaker stands, a pair of 25' Speakon speaker cables, two low-impedance, handheld microphones, and a pair of 20' XLR cables. Yamaha EMX212S The Yamaha EMX212SC is a 12-Channel Powered Mixer equipped with dual 200W amps, 16 Yamaha SPX effects, built-in graphic EQs, and loads of input options. It 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. 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. Yamaha A12 Speakers The Yamaha A12 speaker is a 2-way speaker featuring bass reflex, trapezoidal cab design, heavy grille, recessed handles, and black carpet covering. It is equipped with a 12" woofer, 1" high-frequency horn, 300W program handling (600W peak), and 125dB SPL.
