4 Introduction The MSL-4 self-powered loudspeaker system is ideal for large venues requiring long throw distances and precise coverage, but can also be used effectively in smaller applications. Its high- Q (narrow coverage) horn has a consistent beam width across its entire frequency range, enabling...

If either LED remains on for longer than three seconds, that channel is hard limiting with these negative consequences: • Increasing the input level will not increase the vol- ume. • The system distorts due to clipping and nonlinear driver ...

8 Rigging Two types of rigging hardware are available to ﬂy the MSL-4 loudspeaker system: Aircraft pan ﬁttings and the optional L-Track system. Both are installed and tested exclusively at Meyer Sound Laboratories. Aircraft Pan Fittings Only The MSL-4 without L-Track weighs 184 lb (83.5 kg). The max...

The Lo Cut ﬁlter for CH1 Mid-Hi should be in to correct the LF rise between the MSL-4 and ...

12 Driver Troubleshooting Troubleshooting with TPL The TPL LED can indicate serious driver problems, if interpreted correctly. If one MSL-4 in a system exhibits substantially more TPL activity than others receiving the same audio signal, then one or both drivers in that unit may have a short circuit...

13 Phase poppers are, therefore, not useful for performing phase measurements on an individual loudspeaker or a full-range sound system containing one or more crossovers. If necessary, apply a phase popper only to loudspeakers with identical drivers without a crossover, and check the system’s overal...

14 Array Design Creating an effective array with the MSL-4 requires a precise understanding of how to combine the coverage area and SPL of the individual speaker with those of adjacent speakers. Array design is a trade-off between increasing on-axis power and creating smooth transitions between the ...
