The Bristol Sound & Vision Show 2011, to be held at the Marriott City Centre Hotel from this Friday 25 February until Sunday 27, has sold out. Not for visitors, mind, just to exhibitors, with a staggering 194 home cinema and hi-fi brands on display from 89 separate companies - the largest number for 24 years.

Additionally, the show has been afforded its first app for iPhone/iPad and Android devices, with floor plans and exhibitor lists available for free.

It's part of the universal exhibition application from Proxima Labs, Conventionist, which is available from both iTunes and Android Market, and can therefore be used with other events coming up around the world, tech or otherwise. So, you might even want to keep it installed for further use.

Certainly, it'll help get you around the halls and demo rooms of the Marriott, as the Bristol Show promises to unveil several brand new products for the very first time, including Arcam's AVR400 AV receiver, the first public showing of JVC's 3D HD camcorder (GS-TD1), and a chance to check out Bowers & Wilkins' Apple AirPlay updated Zeppelin Air.

Tickets are still on sale to the general public, and will be available on the days, at £9 for adults, £6 concessions per day, or there's a two-day pass for £15 adults, £10 concessions. Children under 16 accompanied by an adult can visit for free.
