● Using a speaker stand that does not meet the
specifications at left or that is adjusted to a height over
140 cm (55-1/8"), or a leg spread of less than 120 cm (47-
1/4") 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.
