Meyer Sound HMS-10TM - Manual

7 CHAPTER 1: INTRODUCTION HOW TO USE THIS MANUAL Make sure to read these operating instructions in their entirety before 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 encounte...

CHAPTER 1: INTRODUCTION 8 HMS-10 loudspeaker systems require an MPS-488 P exter- nal power supply. The single-space 19-inch rack unit receives balanced 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-pi...

9 CHAPTER 2: THE MPS-488 P POWER SUPPLY The MPS-488 P power supply delivers DC power and bal- anced audio to Meyer Sound loudspeakers that require a 48 V DC external power supply. The MPS-488 P is a multi- channel, switched-mode, regulated power supply that occu-pies one space in a standard 19-inch ...

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 Voltage LEDs, which will all light up). Fuse Slow Blow (1–8) Each loudspeaker channe...

HMS-10 OPERATING INSTRUCTIONS 11 Routing One Input to Four Outputs To route one audio input to four channel outputs: ■ Set all Link switches to ON. Routing Two Inputs to Two Outputs Each To route two audio inputs to two channel outputs each: 1. Set Link switch 3 to OFF and all other switches to ON. ...

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 requirements, see “HMS-10 Current Draw and Cable Requirements” on page 15. For information on cables and cable accessorie...

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

15 CHAPTER 3: THE HMS-10 LOUDSPEAKER THE HMS-10 CONNECTOR The HMS-10 receives DC power and balanced 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 audio (shield, negative, and positive). ...

CHAPTER 3: THE HMS-10 LOUDSPEAKER 16 Cable Lengths and Cable Gauges for HMS-10s 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 AWG wire. Longer cable lengths are possible with heavier wire gauges (see Tabl...

17 CHAPTER 4: MOUNTING THE HMS-10 The HMS-10 comes standard with a fixed bracket; an adjustable bracket is also available for wall mounting the HMS-10 with downtilt or uptilt. This chapter describes how to mount the HMS-10 with these two mounting options. IMPORTANT SAFETY CONSIDERATIONS When install...

CHAPTER 4: MOUNTING THE HMS-10 20 5. Adjust the tilt of the HMS-10 from –13 degrees (downtilt) to +5 degrees (uptilt). Tighten the four side screws to secure the HMS-10. NOTE: Make sure the four side screws are completely tightened to ensure that the HMS-10 won’t move from its desired position. TIP:...

21 APPENDIX A: HMS-10 ACCESSORIES The following HMS-10 accessories are available from Meyer Sound. NOTE: Belden 1502 is a composite cable comprised of two 18 AWG wires for DC power, two 22 AWG wires for balanced audio, and one 24 AWG wire for the audio shield. This single cable can deliver both DC p...

23 APPENDIX B: HMS-10 CABLE ASSEMBLY ASSEMBLING PHOENIX-TO-PHOENIX LOUDSPEAKER CABLES To connect the HMS-10 loudspeaker directly to the MPS-488 P power supply, you need a Phoenix 5-pin female to Phoenix 5-pin female cable. The following procedure documents how to assemble this cable. To assemble a P...

APPENDIX B: HMS-10 CABLE ASSEMBLY 24 3. Secure the conductors by tightening the five screws in the Phoenix connector. 4. Repeat the previous steps and attach the other end of the cable to the other Phoenix connector. 5. Verify the wiring polarity is correct for both connectors. Tighten screws
