PRODUCT PICK OF THE MONTH: The DHA Lighting YoYo+: Walking the Dog

When it last appeared in London in 1979, My Fair Lady held the record as the longest-running show at the Theatre Royal. So when planning the design for its 2001 homecoming, lighting designer David Hersey wanted to ensure there was something new for today's audiences. The traditional way of opening and closing curtains on stage using a simple fade wasn't enough for Hersey's new design for My Fair Lady, so the engineers at DHA Lighting put their heads together — the result is the YoYo+, which was launched at PLASA 2001.

The YoYo+ houses one or two effects plates, accurately positioned in the gate of an ellipsoidal spotlight, and, using a microprocessor controlled motor unit, allows the plates to move either vertically or horizontally to a specific point. The linear movement of the effects plates facilitates any effect that requires vertical or horizontal motion, while the continuous option produces repetitive movement effects. Thus, when Professor Higgins pulls a rope to open the curtains, the outlines of the curtains move back to reveal the windows behind them. [The windows, of course, are also projected, using DHA gobos.]

Careful positioning of the etched image on the YoYo+'s plate means that a pattern can be moved completely in or out of the gate via DMX. And the use of two plates in the double version means that one image can be swapped for another — effectively producing a gobo changer. There is also room for a standard “B”-sized fixed gobo, allowing a whole new range of effects to be created through the interaction of the fixed gobo and the effects plates.

Using digital technology, the YoYo+ is silent and can be connected in a chain of up to 20 units. Control can be accomplished either directly by DMX512 from the console, or up to 60 steps can be recorded onto a programmable chip (EEPROM), for use as a standalone effects unit, such as in a themed setting. Each step can be indexed to +/- 0.35mm. Some of the effects that the YoYo+ can create include image reveals, rising or setting sun, passing car, door opening, curtains closing, bouncing ball, waves on a shore, and swaying trees, just to name a few. In addition to the theatre applications, it is also ideal for advertising and themed entertainment venues. The variety of effects makes the YoYo+ a very versatile tool.

IQ Test, Repeat

Crown Audio introduced updated versions of two products designed for IQ System connectivity - the IQ-INT 3 Interface and IQ-RPT 3 Repeater. The IQ-INT 3 Interface is a simple yet important piece of hardware that bridges the RS232 connector on a host PC to an IQ Bus loop(s) for communication with IQ System components.

The IQ-RPT 3 Repeater is a component that helps an IQ System increase the length of a single IQ Bus loop. By reconstructing the data signal to prevent degradation, the IQ-RPT 3 can typically boost the operating distance of a IQ Bus by 1,000' (305m) or more. Up to 57 repeaters can be added to a single loop, so total loop distance may reach 58,000' (17.7km), or almost 11 miles.

There are two primary improvements on the IQ-RPT 3 and the IQ-INT 3; the new models have eliminated the DIN connectors in favor of RJ-45s. Likewise, status LEDs can now be found on both the front and rear panels of both products.
