The Yamaha STAGEPAS 1K mkII is a portable column PA system combining a powered subwoofer, a 10-driver line-array speaker and an integrated five-channel digital mixer. The speaker and spacers stack into the subwoofer, creating a compact setup without a separate speaker stand or speaker cables. Its three mono channels and stereo line input accommodate microphones, instruments and wired playback, while Bluetooth provides a wireless source for backing tracks or music.

Two mono channels include Hi-Z inputs for directly connecting instruments such as an acoustic-electric guitar or bass. One-knob channel EQ and Speech, Music and Club master modes make basic sound adjustments straightforward. SPX reverb adds effects to channels 1–3, and the Priority Ducker lowers background music when a qualifying speech signal is present. Use it for live music, DJ playback or presentations, and adjust mixer settings remotely with Yamaha’s STAGEPAS Controller app.
