London Marriott Hotel Grosvenor Square - Conference & Event Rooms by CGA Integration


Situated in the heart of Mayfair, the London Marriott Hotel Grosvenor Square delivers its guests both classic sophistication and a contemporary sense of style. As part of a refurbishment programme to ensure continued excellence, CGA Integration worked with the designers RPW Design to specify and install digital signage and AV across The Westminster Ballroom and the adjoining function areas of The Whitehall Suite, offering guests flexible, sophisticated venue spaces with modern facilities.


To minimise any damage to the decorative ceiling within The Westminster Ballroom, CGA Integration needed to install a new sound system and speakers into areas previously used to mount speakers. CGA Integration also faced the challenge of delivering the sound system through very small ceiling voids (100mm) in the adjoining function area of The Whitehall Suite.


The Westminster Ballroom
The Ballroom can be divided into three distinct areas; Belgrave, Chester & Eaton, which can operate independently or in combination with the others. CGA Integration fitted new Evid speakers into existing locations within the Ballroom ceiling to minimise visual impact and a new QSC amplifier and control system was installed, including three radio microphones, five input plates and an iPad control system. Two of the input plates facilitate events companies, as they enable the use of the installed sound system therefore eliminating the need for additional speakers on stands to be positioned along the sides of the room. The iPad controls replicate the lighting wall controls for ease of use and in addition have the facility for advanced lighting functionality, which enables room users and hotel staff to maximise the lighting effects without the need for multiple wall panels and controls.


Ian Pask General Manager of the London Marriott Hotel Grosvenor Square commented ”CGA have installed a flexible quality sound system with future proof technology, which complements our hotel’s desire to offer all guests sophisticated venue spaces with modern facilities”.
