celebrated the 150th anniversary of Canada. These shows added new scenes and lasers. Starlight Spectacular returned again for the 2019 season. Starlight Spectacular updated after COVID-19 for the 2021 season. Apparatus Fountains The 2013 show was designed in consultation with Crystal Fountains, which supplied products including a sequencing fountain and a programmable fountain effect which can move in different directions. For the 2019 season, the Royal Fountain underwent a mechanical reconstruction of the pumps and control infrastructure. This included removing the Hydra constants and upgrading to a modern variable frequency drive (VFD) to precisely control the water jets and create new effects. Most of the fountain lighting effects are produced by 15 Chauvet Legend fixtures installed around the International Street area, and 500 LED lights submerged in the Royal Fountain. Each of the Royal Fountain's 400 water jets has two to three lighting elements. Additionally, two KVANT Spectrum 20 lasers are installed above ground level. The unique control system is patented by the Canada's Wonderland Company, and programmed using a Grand MA 1 lighting desk. Projectors The Starlight Spectacular show uses four Christe Roadster S+20K 3-chip Digital Light Processing (DLP) projectors located just in front of the bridge that crosses the fountain pool. Sound systems Audio units placed along International Street provide sound comparable to a concert audio system, designed to maximize audio levels within the area. As of 2019, the International Street sound system consists of 16 QSC AD-S82H units on the top of each building along the street. This was an upgrade from the 1997 sound system of 10 EV X array audio stacks with sub-woofers. The 1997 sound system had been installed for the pyrotechnic show "The Erruption" (1998–2001). When this show was closed (due to the cost of liquid propane for flame effects), the sound system was mainly used for diving shows and special events, in addition to the background park music. Sound for the 2011–2013 seasons was designed by Tantrum and featured original music from Apollo Studios in Montreal. PM Audio provided sound design from the 2013 season. Audio was designed internally from 2014. Music References Amusement park attractions introduced in 2011 Canada's Wonderland
