Boom

Suspension effect adjustment (SPC only)

The SPC boom features adjustable suspension for 80'-90' booms and
100' booms. The spring (A) has two assembly positions as shown on the
illustration below. Position (1) can be used for 80'-90' booms and
position (2) can be used for 100' booms.
Moving the assembly position further away from center (e.g. from pos. 1
to pos. 2) gives stiffer trapeze effect. The factory setting is position (1).
