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! Theyre 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. 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.
