Both Halls are provided with high specification sound reinforcement systems with Soundcraft 8000 series mixers and recording facilities together with ring intercom, show relay, CCTV, stage management and deaf aid systems. For operatic performances in the main hall, a libretto translation screen uses a Talaria large screen video projector. Conference systems include Auditel 9 language simultaneous interpretation for the Main Hall, video projection and six portable systems for use in meeting rooms. Stage lighting employs 240 channel Galaxy 3 and 60 channel Gemini controls with plug-in dimmers, working light systems and 316 luminaires, including some PALS motorised remote control units in the Chamber Hall. Other centralised low voltage equipment includes box office computer system, paging and radio paging. Subsequent contracts covered provision of post-opening technical assistance as well as portable sound and lighting systems for studio or promenade type performances in the foyer area.
