3 CHAPTER 1 Self-powered and compact, the UPJ-1P combines ad- vanced loudspeaker technology with equally advanced power capabilities. Understanding power distribution, volt- age and current r equirements, as well as electrical safety issues, is critical to the safe operation of the UPJ-1P . AC POWER The UPJ-1P uses a PowerCon 3-pole AC mains system[...]

4 CHAPTER 1 Current Requir ements Each UPJ-1P requir es approximately 3 A rms max at 115 V AC for proper operation. This allows up to ve UPJ-1Ps to be powered fr om one 15 A breaker at 115 V and up to 9 loudspeakers at 230 V . The UPJ-1P presents a dynamic load to the AC mains, which causes the amount of current to uctuate between quiet and l[...]

5 CHAPTER 2 The UPJ-1P uses sophisticated amplication and protec- tion circuitry to pr oduce consistent and predictable r esults in any system design. This chapter will help you under - stand and harness the power of the UPJ-1P amplier and audio systems. The rear panel of the UPJ-1P (Figur e 2.1) provides two slots for processor modules. The [...]

6 CHAPTER 2 Regardless of the input module type, audio signals can be daisy-chained using the loop output connector on the user panel. A single source can drive multiple UPJ-1Ps with a paralleled input loop, creating an unbuf fered har d-wired loop connection. If driv ing mult iple UPJ -1P s in a s yste m, m ake cert ain that the sou rc e de vice c[...]

7 CHAPTER 3 An optional RMS communication module can be installed in the UPJ-1P’ s amplier to make use of Meyer Sound’ s RMS remote monitoring system. RMS is a real-time networked monitoring system that con- nects Meyer Sound self-powered loudspeakers with a Win- dows-based PC at the sound mix position or other desired location. Optional RMS[...]

8 CHAPTER 3 Service LED (Red) When blinking once every two seconds, the Service LED indicates that the network hardwar e is operational, but the loudspeaker is not installed (commissioned) on the network. When a loudspeaker has been installed on the network the, Service LED will be unlit and the Activity LED will ash continuously . NOTE: When co[...]

9 CHAPTER 4 A UPJ-1P loudspeaker system can be deployed in combination with Meyer Sound self-powered USW-1P compact and 650-P high-power subwoofers. These subwoofers can achieve very low frequency r esponse extending system response appr eciably and increasing the overall acoustic power of a system in the lowest frequencies. The USW-1P subwoofer ex[...]

10 CHAPTER 4 Engaging the Lo-Cut lter Using the LD-1A, LD-2 or LD-3 Lo-Cut lter (160 Hz posi- tion on the LD-3) with a system comprising UPJ-1P loud- speaker and subwoofers in close proximity and co-planar will produce a very at fr equency response with a minimal area of overlap. The UPJ-1P loudspeakers in the system receive their signal f[...]

11 CHAPTER 5 Meyer Sound offers two compr ehensive tools to assist you with the acoustical and functional requir ements of system design and optimization. The chapter introduces you to Meyer Sound MAPP Online® - a powerful online acoustical prediction tool – and SIM®, a r obust instrumentation package for system measurement, analysis, and mor e[...]

12 CHAPTER 5 SIM MEASUREMENT SYSTEM SIM is a measurement and instrumentation system including a selection of hardwar e and software options, microphones and accessory cables. SIM is optimized for making audio frequency measur ements of an acoustical system with a resolution of up to 1/24 of an octave; the high resolution enables you to apply pr eci[...]

13 CHAPTER 6 Y ou can easily re-orient the UPJ-1P’ s V ariO rotatable horn to its 80º or 50º conguration and back again. T o rotate the UPJ-1P’ s horn, perform the following steps: 1. Remove the four (4) 10-32 x 5/8" grille cover screws (two from the top and two fr om the bottom) from the UPJ-1P . 2. Carefully r emove the grille. 3. R[...]

15 CHAPTER 7 The UPJ-1P features Meyer Sound’ s QuickFly rigging sys- tem with rugged, reliable and deceptively simple compo- nents. QuickFly facilitates placing UPJ-1P loudspeakers from single units (hanging or attached to a surface) to con- structing rigid, ground-stacked or own UPJ-1P arrays. The UPJ-1P has integral top and bottom plates ma[...]

16 CHAPTER 7 17 CHAPTER 7 POLE-MOUNTING THE UPJ-1P , SINGLE UNIT Y ou can pole-mount the UPJ-1P (Figure 7.3) using a thir d party pole-mount adapter . The two holes used for attaching eyebolts in a basic double-hole conguration (discussed above) can also be used to attach a pole mount adapter . Figure 7.3. Attaching a pole mount adapter (shown u[...]

16 CHAPTER 7 17 CHAPTER 7 Floor Mount The MLB-UPJ can also be used to mount the UPJ-1P on the oor or stage lip, which is useful for monitoring or front- ll applications, for example (Figure 7.8). Figure 7.8. Floor -mounting the UPJ-1P TIP: In any conguration, the MLB-UPJ’ s adjustment slot can be used to increase or decrease the distance[...]

18 CHAPTER 7 19 CHAPTER 7 Horizontal Array The MAA-UPJ array adapter provides a solid connection between multiple loudspeakers to form a horizontal array . The front adjustment slot is used to incr ease or decrease the distance between the front of the loudspeakers and achieve the desired angle between UPJ-1P loudspeakers. The splay angle can be ad[...]
