The primacy and importance of sound in everyday life is obvious to everyone, yet the process of creating an aural presence at an event with excellent results is not widely understood outside of technical circles. Sound, both ephemeral and invisible, does not emit from as ethereal sources. The equipment is often ungainly and the event industry goes to great lengths to make its provisions as visibly unobtrusive as possible, leading to the common misconception that sound equipment is not a major component of an event. It may not have the visual spectacular presence of a huge projection screen or complicated lighting show but there is a lot going on that cannot be seen – but is definitely heard. Getting Your Message Heard The Ins
For the voice of your speaker to be relayed clearly a number of things have to fall in place: You must use the correct microphone in the right position The presenter must use the microphone appropriately Adjustments need to be made to the signal to compensate for issues inherent in the speakers voice You must adjust to any complications in the room’s acoustics And Outs
The signal from the speaker then needs to push out of the loudspeakers at the right volume past your audiences ears. This involves amplification, sending the signal to the right number, size and type of loudspeaker. Obtrusive Visually The balance between acoustic performance, intelligibility and a visually acceptable solution is a delicate compromise. Loudspeaker design and development over many decades has improved their power and aesthetics, but they are still considered an eyesore. Unfortunately the ears are positioned very close to the eyes. Negotiating the ideal blend of practicality and performance takes a skilled and experienced designer. Choosing the Right Music For Your Event Almost everyone has a soundtrack to their lives; the love song that represents a relationship, the album that captured a summer or the music that helps you through a hard time. The correct music choice at an event sets a mood, creates excitement and can be used to create associations between your product or service and a cultural value. Different styles of music can require different types of loudspeakers and amplification. For example, a high-energy sales conference will mostly use up-tempo inspirational music and use volume as a means to animate the crowd. This will require more power and more coverage, quite simply because you need to move more air at a higher energy level. Equipment You will Need
No matter how expensive they are all, all loudspeakers and microphones are imperfect replicators of the original sounds they are trying to distribute or convert. You will need to supplement these with extra equipment. Subwoofers One of the biggest physical limitations in any loudspeaker is its ability to reproduce the entirety of the frequency range audible to humans at the same time. When the frequencies get down to the ‘extended low end frequencies’ created by bass instruments and most synthesizer music (‘doof doof’ techno) they’re physically impossible for a normal low-end driver in a loudspeaker to recreate. Specialised loudspeakers, ‘subwoofers’ or sub-speakers, are dedicated to reproducing frequencies from around 120Hz to 20Hz, which is the bottom of the human hearing range.
These extended low-end frequencies are very important to human understanding of music. We have a very visceral reaction to low end audio, because we feel it more than hear it. Think about adventure films and dance music – the bass delivers the adrenaline. At your next event ask the sound technician to turn off the subwoofers during a rehearsal of your musical cue. You will most certainty hear and feel the difference. Microphones Microphones perform the opposite function to loudspeakers – they take movements in the air and convert them into electrical signals. There are dozens of designs and types that each perform a specific function and most will do a poor job when used on a source they are not designed for. You will probably be surprised by how many microphones are dedicated to just the drum kit in a jazz ensemble. As each individual drum or cymbal has different frequency, volume and tonal characteristics, each needs its own microphone. Eight to twelve yields the best results. Getting the Best Sound from Your Performers Choosing the right equipment, setting it up and operating it correctly are the benchmarks of performance for any sound operator, but it does not guarantee you will have perfect sound. The best sound operator in the world cannot make a bad band sound good! Luckily individual speakers are easier to converse with and adjust. Scared Speakers Some speakers are afraid of the microphone and will stand too far away from it. Even a great sound technician will not be able to generate enough volume for them to be heard. A quick conversation between presenter and sound technician should remedy this. Active Speakers Similarly some presenters are very energetic and are constantly moving around a static microphone. You just need to keep up communication with the presenter about the specifics of the microphone they are using. The best way to ensure a quality performance from your speakers is to have a speakers prep.
Making Sure Your Performers Can Hear Themselves Not just your audience needs to hear your performers but your performers need to hear themselves and each other. The sound mix created for the perfomers is called foldback and can be as simple as a single speaker on the floor of the stage to a complicated map of dozens of separate mixes sent to individual pairs of wireless ear buds.
Usually foldback can be handled by the same mixing desk working with the audience sound, but for large musical and vocal ensembles and events with multiple acts, the best option is to have a separate mixing desk and operator just for the stage sound. Listen Up
Everyone has a story about bad sound; too loud, plagued by feedback, patchy speakers, too hard to understand what was being said… but how many people talk about an excellent sound experience? Sound technicians often speak of the perfect job as being one where they were not noticed at all.

How projection mapping can add an extra dimension to your events
Mar 18 2018
We humans have been fascinated with creating art that fools our eyes and transports us physically since the beginning of civilisation. From perspective tricks in murals to the fake windows on blank building walls of the trompe l’oeil tradition, we delight in deceiving our senses. Now, in the 21st century, 2D and 3D projection mapping are the latest tools of this grand tradition, and are available to you to transform your events in ways that are only limited by your imagination.
Mapping it out
So what does the term ‘projection mapping’ mean, and how does it differ from plain old ‘projection’? Well, we all know what a projection is an image, made of light, beamed onto a screen or surface. It could be a movie, a PowerPoint presentation, or any series of images that gets a point across. Its defining characteristic is that we are clearly aware of its edges, limitations and artificiality. It inhabits a defined space, and our brain sections it off; that’s the projection, and next to it, that’s the wall. Projection mapping has come to mean the use of two or more projectors to extend a continuous image across multiple surfaces, the classic example being four walls. If you are standing in a square white room and a projector shines a photo of the Swiss Alps onto one entire wall, your brain tells you that you’re looking at a projection of a photo. If multiple projectors work together to cover all four walls with a seamless 360 degree panoramic image of the Swiss Alps, your brain starts to think it’s gone skiing. We’re still not totally convinced, but we are enchanted. 2D or not 2D?
Whether we’re talking about 2D or 3D projection mapping is dependent on what we’re actually projecting onto. 2D projection mapping assumes that all the surfaces to be covered are flat screens, walls, or floors. The complexity of 2D projection mapping is in lining up the edges of the beams from multiple projectors and coordinating the projected content so that the eye perceives it all as one big, unbroken image. This is known as Edge Blending.
This takes some serious calculations and very precise physical controls. There are a variety of technologies on the market that help achieve these results. Some brands of projectors have software built-in that, when a physical link is set-up between units with the same capability, detects and manages the activity of all the projectors in the group, enabling them to work as one. Another solution is to use specialised computer software and hardware to control your projectors, which enables the use of whichever projection system is available. 3D projection mapping – no glasses required Event Profile: 3D Projection Mapping from Encore Event Technologies.
3D projection mapping has firmly entered the public consciousness through major public events such as Sydney’s Vivid Festival. The annual event sees the Sydney Opera House, The Museum of Contemporary Art, Customs House and other Sydney landmarks transformed by artists using powerful projectors and complex software. A ballerina dances across the Opera House, Customs House transforms into a 17th century French Palace, and abstract art animates the face of the Gallery. 3D projection mapping is another step up in complexity from 2D. While still drawing on multiple projectors and Edge Blending, it adds the seriously mind-bending task of mapping images onto actual three dimensional objects. In the case of Vivid, it’s a building exterior or architectural feature. Most interestingly, it can also be an object created for the sole purpose of being projected on. It’s this last option that is generating some impressive creative thinking in the events industry. The textbook example of how to use 3D projection mapping for great effect and value for money in a corporate event has come from the auto industry. At recent international car shows and product launches, manufacturers have made blank white foam shells in the shape of their models. Much cheaper and lighter than an actual car, they are easier to ship to the venue. Amazing content is then projected onto the shell that brings it to life as a car. But this car can change colours, finish and details. The projected content can also be video and animation that make the car look like it is driving at speed. Headlights light up, wheels spin and the windscreen reflects the environment flashing past.
Light: portable, flexible and…..light
There’s some pretty obvious advantages to using projection mapping to theme or brand your event. The first is ease of creation, transport and setup. Physical sets and props have to be designed, built, transported and made to work physically in the venue. If your theme was Ancient Greece, for example, you’d need to build and install quite a few fake stone columns to give your guests the impression they’re having dinner in The Parthenon. If you project an image, or better yet, video of the actual Parthenon across all four walls, you’ve done a much better job with a lot less hassle.
If you’re running a roadshow that is staged in many different venues, the efficiencies become even greater. Not only have you saved on freight and labour costs, but the logistical challenges presented by different spaces are completely overcome. Venue specific problems such as low ceilings, small doors and bad lift access that can make bringing in sets a nightmare are all sidestepped by using projection mapping.
Your brand, your way
Despite all of the 3D projection wizardry, the real star of your show is your brand. Projection mapping offers a huge range of opportunities to have your message refreshed and emphasised throughout the event. Because all projected content is dynamic and can be changed subtly or dramatically at will, your branding is no longer relegated to static banners or a single instance on a screen. Your brand can be a brash animated statement on audience entrance, fade to a subtle underpinning during a keynote speech and become part of the room’s architecture in the post-show networking session. The ease of changing projected content also has a positive effect on event timing and management. If a space needs to be reset from lecture to cocktail mode, projected theming and branding doesn’t get in the way like a physical set, one button press and the reset is done. There’s also the ‘Wow’ factor; your audience leaves the lecture hall which has been subtly branded and lit throughout the conference. They return for dinner and enter a totally immersive fantasy world of your choosing. Content is Key
The success of any projection mapping project relies on creating the right kind of content. It’s not just the size and quality of the digital images provided as source material, but the way they are used in service of the event’s goal. It takes practical experience in the use of projection mapping at events to know what kinds of content will work and what won’t when scaled across multiple projectors and blown up to the size of a building. Hint: your iPhone photos probably won’t look that good.
The look and feel of an event needs to be sculpted with both artistic vision and technical know-how. Encore Event Technologies now employs specialist staff to help customers build projected content for events in order to achieve the best possible outcomes. Amazing results can be achieved when technical specialists work hand-in-hand with event organisers to deliver a brief. If your imagination is stimulated by the possibilities of beaming your own world around your audience, start by talking to an expert to determine exactly what they’ll need from you to make it happen. Imagination is your only limitation A blank canvas is a blessing and a curse. Projection mapping enables you to create almost any conceivable visual effect, whether it’s as simple as your logo in three dimensions rotating on a wall, or as complex as your audience being taken on a spaceship through the Milky Way. A coherent artistic vision, well executed, will always have the greatest impact. Consider what the overarching message your audience needs to take away from your event, and focus in on that. All visual material should subtly reinforce that point.
As projection mapping is heavily reliant on computer technology, it’s a rapidly changing field. As more becomes technically possible, creative’s are constantly pushing the boundaries of what can be achieved.
