Yamaha Stagepas 300 Compact PA system No matter where your music leads, Yamaha's new STAGEPAS 300 Portable PA system has the power and portability to go with you. It has all the power and high-quality sound you need to fill a small performance space, yet it is small and light enough to take wherever it is needed. Combining a built-in powered mixer and PA speakers, it's incredibly easy to use - you can be set up and playing in a matter of minutes! STAGEPAS 300 is the perfect road companion, providing powerful, reliable, convenient sound reinforcement for a wide variety of applications. Great sound has never been so portable - and so easy to use. High quality, convenience, and power to go! The powered mixer is normally stored in the rear of one of the speakers. The STAGEPAS? powered mixer can be detached (the only tool you need is a coin) for convenient operation. The power amplifier is a class-D* type that delivers a solid 150 watts + 150 watts from a remarkably compact unit. The mixer has a total of eight input channels: four mono microphone/line inputs and two stereo line inputs. In addition to speaker outputs for the supplied speakers, the STAGEPAS? mixer has line outputs that can be used to connect additional powered speakers for monitoring, or to send the mixer's output to a recording device. * Class-D power amplifiers provide high-efficiency amplification with low power consumption and minimal heat generation, allowing the amplifier to be built into a smaller, lighter, and cooler package. Each mixer channel has an easy-to-use two-band equalizer that can help to shape the sound of each channel to achieve the best possible mix. Boost the highs to give a vocal channel more air and clarity, or boost the lows on a guitar channel for more punch. The four mono input channels have reverb on/off switches, and a reverb level control lets you add just the right amount of reverb to bring your sound to life.
