Gobos

The gobos fitted to the MAC 350 Entour as standard are illustrated in Figure 6 on page 19. All gobos are

interchangeable.

Custom gobos

Martin can provide additional gobos for the MAC 350 Entour. For more information, please visit the Martin

web site at www.martin.com.

Glass gobos are generally the most durable, but satisfactory results can be obtained at less expense with

aluminum gobos. Custom stainless steel gobos can also be used, but they can warp, losing sharpness, in a

matter of hours. Their 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 under “Gobos” on page 44.

Gobo orientation in the MAC 350 Entour

Most gobos must be installed facing in a certain direction in order to avoid heat damage. All MAC 350

Entour gobos MUST be installed with the more reflective side towards the LEDs, or they will absorb too

much heat and be damaged. Consult your Martin dealer or gobo supplier if you are in any doubt about the

orientation of a specific gobo type.

Coated Glass Gobos

Focus is easiest to maintain if all coated gobos in a fixture are installed with their coatings

as close as possible to the same plane of focus. However, if there is a risk of heat damage

on a gobo, the first priority is normally to ensure that the more reflective side faces towards

the LEDs.

More reflective side towards LEDs

To minimize the risk of gobo overheating

and damage, turn the more reflective side of

a coated gobo towards the LEDs.

Less reflective side away from LEDs

The less reflective side of a coated gobo will

absorb less heat if it faces away from the

LEDs.

To determine which side of a gobo is coated,

hold an object up to it. On the uncoated side,

there is a space between the object and its

reflection and the edge of the gobo can be

seen when looking through the glass.

Textured Glass Gobos

Smooth side towards LEDs Textured side away from LEDs

Textured glass gobos in the MAC 350 Entour give the best focus results with the smooth

side towards the LEDs. If in doubt, consult your Martin dealer or gobo supplier.
