Gobos - Martin MAC 700 PROFILE User Manual

Gobos

Gobo wheel 1 provides 6 rotating gobos; gobo wheel 2 provides 9 static gobos. The standard gobo
configuration is shown in Figure 9. Five extra metal gobos are supplied with the fixture. All gobos are
interchangeable with the following limitations:
• On wheel 1, the gobo retention spring works with gobos up to 3 mm in thickness. Thicker gobos can be
glued to the holder with a UV adhesive or Loctite 330 Multibond with Activator.
• Gobo 3 on wheel 1 is glass, and must therefore be changed together with its holder. A spare gobo
retention spring for use with a metal gobo is supplied with the product.
• The maximum thickness for gobos on wheel 2 is 1.1 mm (0.043 inches).

Martin can provide many additional gobos for the MAC 700 Profile. Gobos are interchangeable between
MAC 500, MAC 550 and MAC 700 fixtures. For more information, please visit the Martin web site at
www.martin.com.
For optimum performance and gobo life, custom glass gobos should be made with the artwork reversed on
the coated side and used with the coated side facing away from the lamp.
While glass gobos are generally the most durable, satisfactory results can be obtained at less expense with
aluminum gobos. Custom stainless steel gobos can also be used, however they can warp, losing
sharpness, in a matter of hours. The useful life will depend on the gobo pattern and the projection cycle.
Consult your gobo supplier for more information.
For best results, custom gobos should meet the specifications listed on page 46.
