CAUTION: Suspending any object is potentially dangerous and should be attempted only by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice sanctions suspending the System 200

speakers only when all current national, federal, state and local regulations are taken into account. When the System 200

speaker is suspended, Electro-Voice strongly recommends that the system be inspected at least once a year. If any sign of weakness is detected, corrective action should be taken immediately.

DESCRIPTION

The Mb100 is intended for very simple installations only, to suspend an individual Sx100, Sb120 or Sx200 loudspeaker in a near-vertical orientation (see Figure 1).2 A second, redundant insert point is provided in the top of the enclosure so a supplementary independent means of suspension can be attached when regulations specify. The enclosure can be positioned to angle downward slightly through the use of the pull-up point at the back of the enclosure.

2. The Mb100 Eyebolt Attachment Kit is not recommended for suspension of active systems such as the Sb120a.

• Mounting kit for System 200 speakers: Sx100, Sx200 and Sb120

• Provides three attachment points for secure suspension of a single speaker cabinet

___________________

1. At time of publication, only these models were available in the System 200TM series, but additional models are planned. The general concepts and instructions given here should remain applicable for later models.

The Mb100 Eye-Bolt Attachment Kit contains three lifting eye-bolts which screw into the inserts provided on the System 200TM speakers. The eyebolt attachment points can then be used to suspend the System 200TM speakers using hardware rated for overhead lifting.

Note that two top suspension cables should be used at all times to provide needed stability to the installation (see Figure 4).

enclosures

face down from the ceiling using the Mb100 Eyebolt Attachment Kit. The M8 eyebolts are

not rated for lifting loads at 90°, and such a configuration makes stabilization of the enclosure difficult. Instead, use the Mb200 Installation Kit for this and most other situations.

HANGING INSTRUCTIONS

The speaker is hung using one or two main lifting “chains” with a pull-up point in the back for aiming. Two lifting chains can be used to prevent the speaker from swaying, but both of the rigging hardware (shackles, etc.) must fit through the 20-mm (3/4-in.) opening.

INSTALLATION INSTRUCTIONS

(see Figure 1)

1. From the speaker, remove the plastic hole plugs, gently prying them with a small screw driver.

2. Screw the eye bolt into the insert until the shoulder has contacted the plastic.

3. Finger tighten eye bolt until correct alignment position is obtained, a maximum of one-half turn (see Figure 2). CAUTION: OVER TIGHTENING THE EYE BOLT WITH A WRENCH, SCREW DRIVER, etc. CAN RESULT IN SYSTEM FAILURE AND INJURY.

4. Use certified hardware rated for overhead lifting to suspend the speaker (see Figure 3).

STRENGTH RATING

The Mb100 Eye-Bolt Attachment Kit and the SystemTM 200 speaker enclosure are rated for suspending only one speaker (5:1 safety factor). Hanging any additional weight from the

speaker will exceed its strength rating and create an unsafe condition. Table 2 lists the

strength ratings for the M8 eye bolts. The eye bolts are not rated for angles greater than 45 degrees (see Figure 2). An exception to this would be the eye bolt which is used for speaker aiming and not for a main load-bearing point; the angle on that eye bolt can exceed 45 degrees.
