275 V and allows any combination of voltage to GND (i.e. Neutral-Hot-GND, Hot-Hot-GND). Continuous voltages higher than 275 V may damage the unit. The MSL-6 uses a NEMA L6-20P or IEC 309 male power inlet and satisfies UL, CSA, and EC safety standards. Voltage Requirements...
If the MSL-6 shuts down due to either low or high voltage, the power supply automatically turns on after three seconds if the voltage has returned to either normal operating range.
For example, since the input imped- ance of a single MSL-6 is 10 k , cascading 20 units produces a balanced input impedance of 500 . If a 150 source is used, the 500 load results in a 2.28 dB loss.
Amplification and Protection Circuitry The MSL-6 is 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.
AC power, contact Meyer Sound for repair information. Rigging A single MSL-6 weighs 510 lb (282 kg) and has twelve pivoting lift rings (six on top, six on bottom), each with a maximum working load capacity of 1500 lb (5:1 safety factor).
LD-1A consisting of two rows of two MSL-6s (lower row at 10 to the top row), one row of two MSL-4s with a 30 horizontal splay angle (hung below lower MSL-6 at 20 ), and 650-Ps on the floor. The diagram on the next page displays connections for half of a complete system;...

To insure that the systems combine properly in this area: • Set the MSL-4 to the same polarity as the MSL-6 to phase align the mid-hi frequencies. • Use the CH 5 Array EQ filter to minimize the low- mid rise caused by the MSL-4 array.
MSL-6. The MSL-6 has two rear hatch covers that must be re- moved to access the high and low drivers. Remove the screws for either hatch with a Phillips screwdriver. The hatch is sealed with a rubber gasket so it must be pulled off with moderate force.

6 – 12 dB cancellation in the same range. Polarity Between Adjacent Loudspeakers Use the following test procedure to verify the polarity between adjacent MSL-6 loudspeakers: 1. Position two loudspeakers adjacent to each other. 2. Place a measurement microphone six ft from the speakers on the axis between them.
English • 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.
