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. |
