Vertical tilt
Loosen the vertical locking nut to allow the loudspeaker plate to be tilted to the required position using
the tilt screw (Fig 6.3-5 on previous page).
If the loudspeaker is already attached to the speaker mounting plate, this is much easier to do if you get
a helper to lift the loudspeaker gently whilst you make the adjustment.
Retighten the vertical locking nut once you are happy with the vertical positioning. Then give the tilt
screw a final tweak just to make sure it’s still tight.
Yoke kit
Fig 6.3-7 YF81-K1 yoke kit (all dimensions in millimetres and feet & inches)
The optional YF81-K1 yoke kit allows you to fly your F81
from a truss or 51mm barrel via a standard half-coupler
using the 10mm main fixing hole.
The yoke also has a 6mm safety wire attachment hole.
The F81 has integral M6 side bushes so that the yoke may
be fitted using M6 hex-head bolts and flat washers for fixed
installations.
M6 hand-wheels are available for easy tilt adjustment during
temporary set-ups.
