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 built-in yet detachable mixer of the STAGEPAS 250M provides a total of ten input channels: two mono microphone/line inputs and four stereo line inputs. In addition to a speaker output for the supplied speaker, the mixer has line outputs that can be used to connect additional powered speakers or to send the mixers output to a main mixer or recording device. It also features a convenient PHONES jack for connecting a set of headphones.
