7 CHAPTER 1: INTR ODUCTION HOW TO USE THIS MANUAL Make sure to r ead these operating instructions in their entirety befor e configuring a loudspeaker system with HMS-10s. In particular , pay close attention to material related to safety issues. As you read these operating instructions, you will encounter the following icons for notes, tips, and cau[...]

CHAPTER 1: INTRODUCTION 8 HMS-10 loudspeaker systems requir e an MPS-488 P exter- nal power supply . The single-space 19-inch rack unit receives b alanced audio from its XLR female inputs and routes the audio, along with 48 V of DC power , to its channel outputs. The outputs — equipped with Phoenix 5-pin ma le connectors — can deliver DC power [...]

9 CHAPTER 2: THE MPS-488 P POWER SUPPLY The MPS-488 P power supply de livers DC power and bal- anced audio to Meyer Sound loudspeakers that r equire a 48 V DC external power supply . The MPS-488 P is a multi- channel, switched-mode, r egulated power supply that occu- pies one space in a standard 19-inch rack. The MPS-488 P was originally designed f[...]

CHAPTER 2: THE MPS-488 P POWER SUPPLY 10 NOTE: Since HMS-10s should only be con- nected to channel outputs 1, 3, 5, and 7, only the Load Current LEDs for channels with connected loudspeaker will light up (unlike the V oltage LEDs, which will all light up). Fuse Slow Blow (1–8) Each loudspeaker channel is protected with its own f use. A maximum of[...]

Routing T wo Inputs to T wo Outputs Each T o route two audio inputs to t wo channel outputs each: 1. Set Link switch 3 to OFF and all other switches to ON. Routing Four Inp uts to Four Se parate Outp[...]

CHAPTER 2: THE MPS-488 P POWER SUPPLY 12 Each MPS-488 P comes with Phoenix 5-pin female cable connectors for assembling HMS-10 loudspeaker cables. For information on HMS-10 cable r equirements, see “HMS-10 Current Draw and Cable Requir ements” on page 15. For information on cables and cable accessories available fr om Meyer Sound, see Appendix [...]

HMS-10 OPERATING INSTRUCTIONS 13 ■ Do not use a ground-lifting adap ter or cut the AC cable ground pin. ■ Keep all liquids away from the MPS-488 P to avoid haz - ards fr om electrical shock. ■ Do not operate the unit if the power cable s are frayed or broken.[...]

15 CHAPTER 3: THE HMS-10 LOUDSPEAKER THE HMS-10 CONNECTOR The HMS-10 receives DC power and balance d audio from a Phoenix 5-pin male connector on its top panel. The connec- tor’ s five pins include two for DC power (negative and posi- tive) and three for balanced aud io (shield, negative, and positive). These pins ar e clearly labeled on the HMS-[...]

CHAPTER 3: THE HMS-10 LOUDSPEAKER 16 Cable Len gths and C able Gaug es for HMS-10 s When connecting an HMS-10 to an MPS-488 P channel out- put, you can use cable lengths up to 150 feet with only 1 dB of peak SPL loss using 18 A WG wire. Longer cable lengths are possible with heavier wir e gauges (see T able 2 and T able 3). The maximum cable length[...]

17 CHAPTER 4: MOUNTING THE HMS-10 The HMS-10 comes standar d with a fixed bracket; an adjustable bracket is also available for wall mounting the HMS-10 with downtilt or uptilt.
