11. Only use attachments/accessories specified by Meyer Sound. 12. Use only with the caster rails or rigging specified by Meyer Sound, or sold with the loudspeaker. Handles are for carrying only. 13. Unplug this loudspeaker during lightning storms or when unused for long periods of time. - Page 4 SAFETY SUMMARY English To reduce the risk of electric shock, dis- connect the loudspeaker 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. The receptacle must be connected to a fuse or circuit breaker.

JM-1P can be deployed in tightly- packed array clusters to deliver coverage that is propor- tional to the number of units in the array. While JM-1P point source arrays are optimized for horizontal installations, they can also be used vertically when necessary. With its scal-... - Page 8 JM-1Ps in arrays. The optional MPA-JM1 pickup plate suspends JM-1P horizontal arrays of up to four units with uptilt or downtilt from a single hanging point; two pickup plates can suspend arrays of up to six units from a single hanging point or motor using the MTGSB-4B spreader bar.

Page 10: Power Connector Wiring
AC Connections with VEAM Cabling The JM-1P can be ordered from the factory with a VEAM all- in-one connector. VEAM connectors consolidate AC power, audio, and RMS into a single cable, facilitating easy connec- tions and quick setups. -
Page 11: Jm-1P Current Requirements
If necessary, contact Meyer Sound for repair information. JM-1P CURRENT REQUIREMENTS The current draw for the JM-1P is dynamic and fluctuates as operating levels change. Since different cables and circuit breakers heat up at varying rates, it is important to under- stand the following types of current ratings and how they affect circuit breaker and cable specifications. -
Page 12: Electrical Safety Issues
AC power cable must be rated for the total cur- rent draw of all loudspeakers looped from the power source. Do not operate the unit if the power cables are frayed or broken. Keep all liquids away from the JM-1P to avoid hazards from electrical shock. -
Page 13: Chapter 3: Amplification And Audio
The user panel on the back of the JM-1P has two slots for modules. The top slot contains an audio input module (described in this chapter). - Page 14 Limit LEDs The low- and high-frequency drivers for the JM-1P are pow- ered by separate amplifier channels, each with their own limiter. Limiting activity is indicated with the two yellow Limit LEDs.

Page 15: Amplifier Cooling System
AMPLIFIER COOLING SYSTEM The amplifier for JM-1P uses natural convection for cooling at low to moderate audio levels; for high audio levels, it uses Meyer Sound’s proprietary QuietCool fan technology to pre- vent overheating. The QuietCool™ fan only engages at high audio levels, making it virtually inaudible. - Page 16 CHAPTER 3: AMPLIFICATION AND AUDIO...

Page 17: Chapter 4: Adding Subwoofers To A Jm-1P Loudspeaker System
NOTE: When JM-1P loudspeakers and 700-HP subwoofers are daisy-chained using the JM-1P’s Loop connector, the result is a fairly flat frequency response. However, the response will show an increase in the 60 Hz – 200 Hz range where the loudspeaker and subwoofer overlap at certain ratios (see Table 2). -
Page 18: Using Digital Signal Processors
If a digital signal processor is used, both the JM-1P loud- speakers and subwoofer should be driven from the same processor to keep their delay times the same. Otherwise a phase shift between the JM-1Ps and subwoofer may be encountered. -

THE JM-1P GUIDEALINKS The JM-1P is equipped with GuideALinks on its four right cor- ners that attach to an adjacent JM-1P with the links inserted in the left corner slots of the linked unit. GuideALinks are extended and retracted with front and rear knobs. - Page 20 CHAPTER 5: QUICKFLY RIGGING The JM-1P Quick-Release Pins Each JM-1P ships with four quick-release pins that secure the units when they are linked. When inserting and removing the pins, press the button at the top of the pin to disengage it.

Meyer Sound loudspeaker mea- surements. Performance predictions for each loudspeaker are based on 360 1/48th-octave-band measurements taken with a SIM audio analyzer in the Meyer Sound anechoic chamber. The extraordinary consistency between Meyer Sound loudspeakers guarantees that predictions from MAPP Online Pro will closely match their actual perfor- mance. -
