When you need a quick, portable sound system you can turn to the Yamaha STAGEPAS 150M. It was designed for musicians (especially keyboard players) but it will work in lots of different applications.

Power to Go!
From the company known for market-leading electronic keyboards come a new generation of keyboard amplifiers that redefine the category: STAGEPAS 150M and 250M. "How are they different from what's been available?" you ask. In almost every way! They're much lighter and more compact, provide a unique form factor and feature set optimized for keyboardists, and, most importantly, deliver the ultimate in sound quality. Both of these single-speaker systems also function very effectively as ultra-portable mono PA systems that are upgradeable to stereo with the simple addition of an optional powered speaker.

Flexible 8-channel Powered Mixer
The STAGEPAS 150M provides a total of eight input channels: two mono microphone/line inputs and three stereo line inputs. Along with the output for the supplied speaker, the built-in yet detachable mixer also has line outputs that can be used to connect additional powered speakers or to send the mixer's output to a main mixer or recording device. A convenient PHONES jack is also included for connecting a set of headphones.

Exceptionally Compact System – 8 Channels, 150 Watt Output 150 Watt Class D Power Amplifier
This power amplifier is all you'll need for most small venues and street performance situations, as well as personal monitoring applications. The advanced Class-D design delivers exceptional efficiency ensuring high power amplification with low power consumption and minimal heat generation. This means you get superior sound quality and reliability in a remarkably compact unit.

Ideal for Monitor Speaker Use
The STAGEPAS 150M is also effective as a monitor speaker system (especially for keyboard players, drummers and solo performers), thanks to its fullrange reproduction, convenient mixing controls, and versatile speaker placement.

Speaker Stand Mountable (with optional accessory)
The STAGEPAS 150M speaker can be mounted onto a standard speaker stand, using an optional mount adaptor such as the ADP138, the Ultimate BMB200, or an equivalent.
