Installation and use of Installation Series speakers should only be performed by a qualified certified rigger in accordance with the recommendations contained within the Rigging Guide and Owner’s Manual. These products are for use only by certified and qualified professionals and individual consumer use is not recommended or intended. Please consult an appropriate professional about installation or use of Installation Series speakers. 1.
2. Do not allow inexperienced persons to carry out installation. Installation personnel should be trained in loudspeaker mounting / flying techniques in accordance with the level of skill required for the job. 3. Always inspect all components - the cabinets, supplied eyebolts and any third party accessories - for damage before assembly. If you suspect any component to be sub-standard DO NOT use the affected part, but contact the manufacturer immediately and arrange alternative parts. 4.
only, and may not match actual appearances during operation. Some fittings may deteriorate due to wear and/or corrosion. Rigging systems and rigging accessories, including all eyebolts and speaker brackets provided by Yamaha, need to be checked thoroughly for fatigue at regular intervals to ensure maximum safety. (Intervals may vary, please contact your rigging expert for more information.
e.g. Omnimount / Multimount / Powerdrive / Ohashi / König & Meyer etc. These allow mounting at many different angles and orientations. • From truss / scaffolding bars For applications requiring occasional or frequent moving of loudspeakers, “fly frames” offer a convenient solution. They can also be used in permanent situations when a loudspeaker requires a great degree of tilt, or where steel wires would be unsightly.
The front two wires provide the primary support, whilst the rear point enables the cabinet to be tilted, or ‘kelped’. In most instances of the configuration, the cabinet can be flown with fixed length steels or chains for the front two points. Aside from safety reasons, a minimum of three points are practically needed to provide the degree of positioning required, and prevent rotation. The rear point should have a device which allows the length to be adjusted, while in the air, to enable accurate aiming.
Minimum of three or four rigging points are required when using an array frame.
10. Check the structure prior to mounting Check the structure to be mounted from (ceiling, roof beam etc). If in any doubt whatsoever, consult a suitably qualified structural engineer. 11. Use of Eye bolts The eye bolts supplied with your Yamaha Installation Series speakers are not common eye bolts that you would find at your local hardware store. The supplied eye bolts are actually hardened, load-rated lifting eyes and are much stronger than common eye bolts. Do not substitute.

Bridle installation should only be installed by a certified rigger or installed after consultation and with supervision by a certified rigger. 14. Enclosures capability IF2112, IF2115 and IS series subwoofer enclosures are capable of a maximum load of 60Kg , or 132 lbs per single rigging point. (10:1 safety ratio. That means they passed 600Kg, or 1320 lbs weight test) *At 7:1 ratio, maximum load is 85Kg, or 188 lbs. (600kg / 7) *At 5:1 ratio, maximum load is 120Kg or 264 lbs.

15. Ground stacked systems Loudspeakers that need to be portable or re-configured on a regular basis for a venue like a performing arts center or multi-purpose facility can be ground stacked for convenience. All ground stacked speakers, especially in locations where public may gain access to the systems (e.g. stages in music venues), even if unauthorized, should have the system permanently anchored down (e.g. by load straps). Always check the supporting surface (e.g.
General advice includes: • Ensure the stand is not placed where it will be a trip hazard • Ensure the stand is rated to take the weight of the speaker comfortably • Ensure the legs are splayed out sufficiently to prevent toppling 17. Loudspeaker cables From a rigging perspective, there are a number of points to consider regarding loudspeaker cables: 1. The “self” weight of the cable must be factored in to the total load to be flown.
