Using a Speaker Stand
:
The stability using speaker 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.
By using a non-Roland specified speaker stand, you can mount the AC-90 at the optimal height for use as a monitor speaker or
simple PA device.
Use a speaker stand that is strong and durable, such as
one made from aluminum.
The AC-90 is designed to be used only with speaker
stands whose dimensions meet the specifications
described below.
Do not use it with a speaker stand that does not meet the
following specifications.

Before use, adjust the speaker stand to a height of 114 cm
(44-15/16") or less and a leg spread of 98 cm (38-5/8") or
more, as shown in the figure below.

Using a speaker stand that does not meet the
specifications at left or that is adjusted to a height over
114 cm (44-15/16"), or a leg spread of less than 98 cm (38-
5/8") may result in damage to equipment or injury due to
the stand tipping over.
When using the AC-90 with a speaker stand, the speaker
stand must be carefully placed so it is level and sure to
remain stable.
Cables connected to the AC-90 should be given enough
slack to prevent accidents that might result from someone
tripping over them.
To prevent accidents due to falls, do not place any object
on the AC-90 when it's mounted on a speaker stand.
Always have at least one other person assist you when
mounting the AC-90 on a speaker stand, or when
adjusting the height of the stand while the AC-90 remains
mounted on it.
