3 Introduction The MSL-6, Meyer Sound’s largest self-power ed speaker , is ideally suited for large-scale vocal public addr ess applications as a stand-alone system, and for musical sound reinfor cement in combination with Meyer self- powered subwoofers and/or the DS-2P mid-bass speaker .
4 If the voltage decreases below the lower bound of either operating range ( brown-out ), the supply uses stor ed energy to continue functioning briefly . The unit turns of f if the voltage does not increase above the thr eshold before the storage cir cuits are depleted.
5 Safety Issues Pay close attention to these important electrical and safety issues. Use a power cord adapter to drive the MSL-6 from a standard 3-prong outlet (NEMA 5-15R;125 V max). earth ground chassis ground The MSL-6 requires a grounded outlet. Always use a grounding adapter when connecting to ungrounded outlets.
6 Amplification and Protection Circuitry The MSL-6 i s powered by the Meyer MP-4, a four - channel 2480 W amplifier (620 W/ch) utilizing comple- mentary power MOSFET output stages (class AB/H). The following sections discuss the MP-4’s limiting circuitry and four-fan cooling system.
7 Fans and Cooling System The MSL-6 uses a forced-air cooling system with four fans to prevent the amplifiers fr om overheating. The fans draw air in through ducts on the fr ont of the cabinet, over the heatsinks, and out the rear of the cabinet. Since dust does not accumulate in the amplifier circuitry , its life-span is increased significantly .
8 Measurement and System Integration Measurement and corr ection tools are requir ed to assemble a complete sound system, particularly when the venue requir es precise array design, delay systems, or compensation for significant reverberation.

10 Driver T roubleshooting The Remote Monitoring System (RMS) is the best method to query the status of the drivers in a system before and during the performance.
11 Use the following test to verify polarity between high and low frequency drivers: 1. Place a monitoring microphone 5 ft from the grill frame, 24” below the top of the cabinet, at the mid- point between low drivers (center-line of cabinet). 2. Connect a signal source to the loudspeaker and note the frequency response.

13 • To reduce the risk of electric shock, disconnect the loud- speaker from the AC mains before installing audio cable. Reconnect the power cord only after making all signal connections. • Connect the loudspeaker to a two-pole, three wire grounding mains receptacle.
