D n Figure 6a Figure 6b In order to comply with relevant fire safety regulations i e BS 5839 1998 it is required that in the event of fire that failure of the circuit to which the loudspeaker is connected does not occur before evacuation of the building is complete Suitable measures include a use of terminal blocks for connection to primary with a melting point of not less than 650 for example constructed from ceramic materials use of terminal blocks of a lower melting point but protected with thermal insulation d useofterminal blocks such that on melting an open circuit or a short circuit does not occur 7 Equalization The CMS60 ICT 30 CMS60 ICT 4 is designed to need no equalization or correction to overcome system limitations As a result it will only need equalization to compensate for difficult acoustic environments Excess equalization can reduce system headroom and introduce phase distortion resulting in greater problems than it cures If equalization is required then it should be applied gently and smoothly Violent equalisation will be detrimental to the overall sound quality If the loudspeakers were being used consistently at high levels it would be beneficial to introduce a high pass filter at 50Hz to protect the loudspeaker from any unnecessary subsonic frequencies 8 Dimensions 334mm 305mm 12 9 Performance Data 50 100 200 500 Tk ek 10k ek Frequency Hz U
