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 MM-10s.
CHAPTER 1: INTRODUCTION 8 The MM-10XP Subwoofer The MM-10XP is power ed by an external 48 V DC power supply , eliminating the need for wiring conduits while still preserving the ad vantages of self-powered loudspeaker systems.
9 CHAPTER 2: THE MM-10XP SUBWOOFER The MM-10XP is power ed by an external 48 V DC power supply , eliminating the need for wiring conduits while still preserving the ad vantages of self-powered loudspeaker systems.
CHAPTER 2: THE MM-10XP SUBWOOFER 10 THE MM-10XP INPUT POLARITY SWITCH The Input Polarity switch swaps the polarity of the audio source signal, which is sometimes necessary to acoustically align the subwoofer with other loudspeakers in the system.
MM-10 OPERATING INSTRUCTIONS 11 MM-10XP T emperatur e and Limiting The Limit LED turns solid yellow when its heat sink tempera- ture r eaches 65° C (145° F), indicating the unit is reaching its maximum heat dissipation and a r eduction in SPL is recom- mended.
CHAPTER 2: THE MM-10XP SUBWOOFER 12 WIRING MM-10XP LOUDSPEAKER CABLES WITH BELDEN 1502 CABLE When wiring MM-10XP loudspeaker cables with Belden 1502 or an equivalent cable, use the conventions in T able 3. The red and black w ires in the Belden 1502 cable have a thicker gauge than the other thr ee wires and should be used for DC power .
13 CHAPTER 3: POWERING MM-10XP SUBWOOFERS WITH THE MPS-488HP The MPS-488HP power supply delivers DC power and bal- anced audio to Meyer Sound loudspeakers that r equire a 48 V DC external power supply .
