SAFETY SUMMARY English ■ ■ ■ To reduce the risk of electric shock, disconnect 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. Connection to any other type of receptacle poses a shock hazard and may violate local electrical codes.

CHAPTER 1: INTRODUCTION HOW TO USE THIS MANUAL THE HMS-10 SURROUND LOUDSPEAKER 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. Meyer Sound's HMS-10 is a full-range, two-way loudspeaker optimized for surround channels in theatres and rerecording stages.
CHAPTER 1: INTRODUCTION HMS-10 loudspeaker systems require an MPS-488P external 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-pin male connectors — can deliver DC power to up to four HMS-10 loudspeakers at cable lengths of up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire.
CHAPTER 2: THE MPS-488P POWER SUPPLY The MPS-488P power supply delivers DC power and balanced audio to Meyer Sound loudspeakers that require a 48 V DC external power supply. The MPS-488P is a multichannel, switched-mode, regulated power supply that occupies one space in a standard 19-inch rack. The MPS-488P was originally designed for use with the MM-4XP miniature loudspeaker.
CHAPTER 2: THE MPS-488P POWER SUPPLY NOTE: Since HMS-10s should only be connected 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). Channel Inputs Up to eight channels of balanced audio are received from the MPS-488P’s eight channel inputs. The inputs are equipped with XLR female connectors (pin 1, ground; pin 2, signal positive; pin 3, signal negative).
HMS-10 OPERATING INSTRUCTIONS Routing One Input to Four Outputs Input Impedance for Linked Channel Inputs To route one audio input to four channel outputs: When a Link switch is enabled, the channel input’s unbuffered source signal is transmitted in parallel to each linked channel output. This causes the channel input’s impedance (normally 10 kOhms for one HMS-10) to be reduced for each linked channel output. For example: ■ Set all Link switches to ON.
CHAPTER 2: THE MPS-488P POWER SUPPLY Each MPS-488P 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 accessories available from Meyer Sound, see Appendix A, “HMS-10 Accessories.” For information on cable assembly, see Appendix B, “HMS-10 Cable Assembly.
HMS-10 OPERATING INSTRUCTIONS ■ Do not use a ground-lifting adapter or cut the AC cable ground pin. ■ Keep all liquids away from the MPS-488P to avoid hazards from electrical shock. ■ Do not operate the unit if the power cables are frayed or broken.

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 connector’s five pins include two for DC power (negative and positive) and three for balanced audio (shield, negative, and positive). These pins are clearly labeled on the HMS-10 top panel. The connector accepts conductors up to 12 AWG (American Wire Gauge) or 2.5 mm2. To function properly, the HMS-10 requires 48 V of DC power.
CHAPTER 3: THE HMS-10 LOUDSPEAKER Cable Lengths and Cable Gauges for HMS-10s When connecting an HMS-10 to an MPS-488P channel output, 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 Table 2 and Table 3). 4. Connect up to four HMS-10 loudspeakers to the MPS-488P channel outputs. Connect only to channel outputs 1, 3, 5, and 7.
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 MOUNTING THE HMS-10 WITH THE FIXED MOUNT BRACKET The HMS-10 can be mounted with a fixed mount bracket at a fixed angle of 0 degrees. The low profile bracket allows the HMS-10 to be mounted less than 0.
CHAPTER 4: MOUNTING THE HMS-10 To mount the HMS-10 with the fixed mount bracket: 1. Disassemble the fixed bracket by removing the two bottom screws. Separate the wall plate from the loudspeaker plate (labeled “Monitor”). Leave the loudspeaker plate attached to the HMS-10. ■ – Drill two 1/8” pilot holes, 2.0 inches deep, at the marked locations. – Secure the wall plate to the wall with the two wood screws.
HMS-10 OPERATING INSTRUCTIONS MOUNTING THE HMS-10 WITH THE ADJUSTABLE MOUNT BRACKET 2. Choose one of the following mounting options: ■ The HMS-10 can be wall mounted with the adjustable mount bracket at downtilt angles up to 13 degrees and uptilt angles up to 5 degrees (uptilt). To mount the HMS-10 on a wall with a wood stud: – Locate the stud and mark two mounting holes on the wall using the wall plate’s center mounting slots as a guide. 5.16 [131.06 mm] 4.75 [120.
CHAPTER 4: MOUNTING THE HMS-10 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. -13° NOTE: When mounting the HMS-10 in a soffit, allow at least 3 inches above the unit to provide the necessary ventilation for its amplifier and heat sink.

APPENDIX B: HMS-10 CABLE ASSEMBLY ASSEMBLING PHOENIX-TO-PHOENIX LOUDSPEAKER CABLES To connect the HMS-10 loudspeaker directly to the MPS-488P power supply, you need a Phoenix 5-pin female to Phoenix 5-pin female cable. The following procedure documents how to assemble this cable. Assembled Phoenix-to-Phoenix Cable To assemble a Phoenix-to-Phoenix cable: 1. If the cable has not yet been stripped, strip one end of the cable.
APPENDIX B: HMS-10 CABLE ASSEMBLY 3. Secure the conductors by tightening the five screws in the Phoenix connector. Tighten screws 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.
