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 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 cinemas, theatres, and re-recording stages.
CHAPTER 1: INTRODUCTION Balanced audio and DC power are received by the HMS-10 from a Phoenix™ 5-pin male connector on its top panel. Powering the unit from an external source eliminates the need for wiring conduits while still preserving the advantages of self-powered loudspeaker systems. The HMS-10's amplifier and signal-processing circuits store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs.
CHAPTER 2: HMS-10 LOUDSPEAKER HMS-10 INPUT CONNECTOR The HMS-10 receives DC power and balanced audio from its Phoenix 5-pin male connector on the top panel. The connector’s five pins include two pins for DC power (negative and positive) and three pins 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.
CHAPTER 2: HMS-10 LOUDSPEAKER Calculating the Maximum Cable Length The maximum cable length for an HMS-10 can be calculated with the following formula: maximum length = 2 ohms / 2 * cable resistance For example, the maximum length of an 18 AWG cable with a resistance of 0.00636 is 157.2 feet (2 / 2 * 0.00636). WIRING HMS-10 LOUDSPEAKER CABLES WITH BELDEN 1502 CABLE (OR EQUIVALENT) When wiring HMS-10 loudspeaker cables with Belden 1502 cable, use the conventions in Table 3.
CHAPTER 3: POWERING HMS-10 LOUDSPEAKERS CONNECTING HMS-10 LOUDSPEAKERS TO THE MPS-488HP EXTERNAL POWER SUPPLY HMS-10 loudspeakers require a Meyer Sound 48 V DC external power supply, such as the MPS-488HP. The singlespace 19-inch rack unit receives eight channels of balanced audio from its XLR female Channel Inputs and routes the audio, along with 48 V of DC power, to its eight Channel Outputs.
CHAPTER 3: POWERING HMS-10 LOUDSPEAKERS CONNECTING HMS-10 LOUDSPEAKERS TO THE MPS-488 EXTERNAL POWER SUPPLY The original MPS-488 was designed for use with the MM-4XP miniature loudspeaker. While the MPS-488 can power up to eight MM-4XP loudspeakers, it can only power up to four HMS-10 loudspeakers (due to the HMS-10’s higher power requirements and current draw).
CHAPTER 4: MOUNTING HMS-10 LOUDSPEAKERS 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 HMS-10 LOUDSPEAKERS 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 HMS-10 LOUDSPEAKERS 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 HMS-10 LOUDSPEAKERS 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 HMS-10 LOUDSPEAKERS 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 CAUTION: When wiring HMS-10 loudspeaker cables, it is extremely important that each pin be wired correctly. Make sure the 48 V DC from the external power supply is wired directly (and only) to the 48 V DC pins on the HMS-10 loudspeaker connector, and that the polarity is observed (negative to negative, positive to positive) to avoid damage to the loudspeaker.
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.
