Placement

The volume and tone quality will be affected by how far from the wall you place the main unit and the satellite speakers, as well as by the material of the wall and the characteristics of the floor. While you listen to the sound, adjust the position and volume as appropriate for your location.

Placing the Satellite Speakers

We recommend that you place the satellite speakers at two corners of an equilateral triangle, with the listening position at the third corner.

Point the front of each satellite speaker so that it faces the listening position.

Placing the Main Unit

It's best to place the main unit (subwoofer) at the same distance as the satellite speakers, with the listening position at the center.

Ensuring a natural link between the main unit (subwoofer) and the satellite speakers ([PHASE] switch)

The [PHASE] switch switches the phase of the main unit (subwoofer). Choose either the "NOR" (normal) or "INV" (inverse) setting, whichever produces the most natural link between the main unit (subwoofer) and the satellite speakers.

Using Microphone Stands

The stability using microphone stands other than the folding stand integral with the speaker has not been evaluated for safety and can result in hazardous injury to the user.

The satellite speakers are designed so that non-Roland specified microphone stands can be used to support them. By mounting the satellite speakers on non-Roland specified microphone stands, you can position them at the optimal height for use as monitors or as a convenient PA system.

The microphone stand holder on the bottom of each satellite speaker provides two holes: 3/8" and 5/8". Use the hole that's appropriate for your microphone stand.

• As shown in the illustration below, open the legs of the microphone stand (50 cm or more), and position it so that the total height (including the satellite speaker) does not exceed 105 cm.
  

• If the microphone stand is higher than 105 cm (including the satellite speaker), or if the legs are not spread out, the stand and speaker may tip over, causing injury or damage.
• When using microphone stands to support the satellite speakers, do not place them at unstable or inclined locations. You must place the stand on a stable and horizontal surface.
• Make sure to appropriately manage the cables connected to the satellite speakers so as to prevent accidents, such as might be caused by someone tripping over them.
• To prevent the stand and speaker from tipping over, do not place anything on a satellite speaker mounted on a microphone stand.
• After mounting a satellite speaker on a microphone stand, be sure to verify that it does not wobble.
• Be sure to get the assistance of at least one other person when mounting a satellite speaker on a microphone stand, or when adjusting the height of the microphone stand while the satellite speaker is mounted.
• Firmly tighten the hardware of the microphone stand so that the satellite speaker does not move to left or right.
• Take care not to pinch your fingers when mounting the satellite speaker.
• Use a microphone stand that is strong and durable, such as one made from aluminium or steel.
