Adlib fixtures installed at The Lowry in Salford Quays

Roger Kirby along with the in-house design and installations team at Liverpool, UK based Adlib have worked again with a new L-Acoustics installation in The Quays Theatre at The Lowry in Salford Quays. The 440 capacity Quays Theatre is a flexible performance space used for staging drama, comedy and a variety of music events, and was upgrading its sound system for the first time since The Lowry complex opened in April 2000. The upgrade project was co-ordinated for the theatre by Dave Woodward, the Head of Technical Services.

A total of six 12XTi full range boxes installed close to the proscenium line make up the core stereo system on all three levels. They work in conjunction with four 8XTs with the first pair of 8s deployed for coverage across the nearfield stalls seating and a second pair providing ‘delayed’ sound coverage for the side-tier stalls seating towards the rear corners of the auditorium.

A ‘Centre-hang’ of L-Acoustics Arcs WiFo Loudspeakers has also been introduced in the centre of the proscenium arch. The hang comprises a single SB18 sub at the top of the array with four Arcs Focus loudspeakers below.

The bottom two Arcs Focus loudspeakers are directed to provide coverage to the centre and rear of the ground level stalls seating. To extend the lower bass and sub frequency capabilities of the system four SB18m Subs have been introduced with a pair located at each side downstage of the proscenium.

The loudspeakers are driven and controlled with a combination of LA8 and LA4 L-Acoustics proprietary amplifiers which have been installed in the main legacy sound and communications racks. LA-Network manager allows the operating sound engineers control and optimisation of each individual loudspeaker within the installed system.

For live events requiring higher impact sound coverage at increased sound pressure levels (primarily for any band performances in the space), four Arcs II loudspeakers compliment the system, these form conventional Left & Right PA stacks with the four repositioned SB18ms.

Adlib has also supplied a secondary portable amplifier rack allowing ‘racks-and-stacks’ to be moved to other locations in The Lowry complex. This allows the Arcs II/SB18m stacks and 12XTi/8XTi series Loudspeakers to be operated outside of the Quays Theatre space as and when required.

Some of the house signal and loudspeaker circuits already in place were modified and optimised to facilitate the new loudspeaker system, this included the extension of some loudspeaker cable circuits and the relocation of others. The main signal patch-bay was also extended and modified to simplify signal connectivity from a variety of in-house mixing desks including Soundcraft and Yamaha consoles.

At Woodward’s request, Adlib engineers re-used as much of the original system infrastructure as possible. This included redeploying a number of loudspeakers circuits that had previously seen limited use due to their original placement.

When initially considering loudspeaker placement for the space there were a number of restrictions including the venue’s stage width and format combined with relatively low ceiling heights at all nearfield side seating positions. Therefore a series of mechanical extension brackets were supplied and installed allowing greater distances to be maintained between the nearest seats to and the proscenium 12XTs on upper tiers.
