This Roland PM - 3 personal monitor system comes as a woofer unit only. It does not include the original left and right external speakers. All that's included is what you see in the photos. The package includes the correct power supply. However, there's a known issue where the 'High' knob is not functioning.

To use this Roland PM - 3 personal monitor system, first make sure you connect it to the correct power supply included in the package. Since it doesn't have the original left - and - right external speakers, you'll need to use your own compatible speakers if you want a full - range audio experience. When you turn it on, be aware that the 'High' knob doesn't work, so you won't be able to adjust the high - frequency settings. For maintenance, keep the unit in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. If you notice any other problems, it's best to consult a professional audio technician.
