Boom

Suspension effect adjustment (80'-100' SPC only)

The SPC boom features adjustable suspension for 80'-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).
