This year the Empire undertook a third refit within the last 17 years. After it’s second refit around the turn of the 20th century with a rather disappointing Martin Audio five-screen loudspeaker array and surrounds while the original JBL of x8 JBL 4645 18” sub bass speakers remained behind the screen. Now was the time to give her back a real punch.



The JBL 4645C Sub Bass cluster is 8 feet and 9” high and 13 feet and 10” wide!!!!!!!





The spec as follows:-

Dolby CP650SD (10 channel AES/EBU Output Studio version)
Dolby CP200/DA20/MPU-1/SA10 retained for 70mm magnetic and backup replay. CP200 Modified with CAT 64B EQ cards removed for lower noise operation.
2x SDDS DFP2000 (One main, one backup)

5x DBX4800 24bit/96Khz Loudspeaker Management Systems with HiQNET Control. Digital Feed from CP650, Analogue Feed from CP200/SDDS.

5x JBL Custom Screen Array each fed by 1x Crown CTs2000 and 1x Crown CTs3000 Amplifiers

16x JBL 4645C Sub Bass fed by 8x Crown CTs 3000 Amplifiers

42x JBL 8340A Surround Loudspeakers individually driven and time-aligned from 6x Crown CTs8200 8-Channel Amplifiers

Total System Power 56kW

The system now carries THX license

Screen size has now been increased to a maximum 18.26x8.14m
