SAFETY SUMMARY English ■ ■ ■ To reduce the risk of electric shock, disconnect the apparatus from the AC mains before installing audio cable. Reconnect the power cord only after making all signal connections. Connect the apparatus 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 MPS-488HP EXTERNAL POWER SUPPLY Make sure to read these operating instructions in their entirety before configuring a loudspeaker system with MPS-488HP power supplies. In particular, pay close attention to material related to safety issues. The MPS-488HP external power supply delivers DC power and balanced audio to up to eight Meyer Sound loudspeakers that require an external 48 V DC power supply.
CHAPTER 1: INTRODUCTION ticonductor cables (such as Belden® 1502 or equivalent) allows a single cable to carry both audio and DC power from the MPS-488HP to the loudspeakers. Longer cable lengths are possible for moderate applications that don't drive the loudspeakers to maximum output, as well as for installations with heavier wire gauges.
CHAPTER 2: MPS-488HP FRONT AND REAR PANELS MPS-488HP FRONT PANEL Blue Voltage LEDs (1–8) The MPS-488HP front panel includes a power switch and LEDs for monitoring each loudspeaker channel. The blue Voltage LEDs indicate whether voltage is present for the Channel Outputs. These LEDs should be lit when the MPS-488HP is powered on. The MPS-488HP’s intelligent circuit protection shields connected loudspeakers from surges and shorts.
CHAPTER 2: MPS-488HP FRONT AND REAR PANELS Green Load Current LEDs (1–8) MPS-488HP REAR PANEL The green Load Current LEDs indicate whether loudspeakers are connected to the Channel Outputs and receiving power. As a channel’s audio signal increases, its LED glows brighter. If an LED is not lit, check that the channel’s Voltage LED is lit and verify the cable connection to the loudspeaker. The MPS-488HP’s intelligent circuit protection shields connected loudspeakers from surges and shorts.
MPS-488HP OPERATING INSTRUCTIONS Link Switches Routing Two Inputs to Four Outputs Each Link switches determine how Channel Inputs are routed to Channel Outputs. When a Channel Input’s Link switch is OFF (set to the down position), the input is only routed to its corresponding output: for example, Channel Input 1 routed to Channel Output 1.
CHAPTER 2: MPS-488HP FRONT AND REAR PANELS To avoid distortion when linking Channel Inputs, make sure the source device can drive the total load impedance of the linked loudspeakers. The source device must be capable of delivering a minimum of 16 dBV (6.3 V rms into 600 ohms) to yield the maximum peak SPL over the operating bandwidth of the loudspeaker. NOTE: Most source devices are capable of driving loads no smaller than 10 times their output impedance.
MPS-488HP OPERATING INSTRUCTIONS MPS-488HP CURRENT DRAW SAFETY ISSUES The current draw for the MPS-488HP and its connected loudspeakers is dynamic and fluctuates as operating levels change. Since different cables and circuit breakers heat up at varying rates, it is important to understand the following types of current ratings and how they affect circuit breaker and cable specifications. Pay close attention to these important electrical and safety issues.

CHAPTER 3: CONNECTING LOUDSPEAKERS TO THE MPS-488HP NOTE: For information on cable requirements for your loudspeaker, refer to its operating instructions. For information on cables and cable accessories available from Meyer Sound, see Appendix A, “MPS-488HP Accessories.” For information on cable assembly, see Appendix B, “Phoenix and EN3 Cable Assembly.” CAUTION: When wiring cable connections for MPS-488HP Channel Outputs, it is extremely important that each pin in the connector be wired correctly.
CHAPTER 3: CONNECTING LOUDSPEAKERS TO THE MPS-488HP ■ When connecting loudspeakers equipped with EN3 connectors to the MPS-488HPe power supply, use EN3 5pin male to EN3 5-pin female cables. 5. Power on the MPS-488HP and monitor the LEDs on its front panel to verify the connections (see “Voltage and Load Current LEDs (1–8)” on page 9). 6. Check loudspeaker LEDs to verify whether the loudspeakers are ready to reproduce audio. 7.

APPENDIX B: PHOENIX AND EN3 CABLE ASSEMBLY CAUTION: When wiring cable connections for MPS-488HP Channel Outputs, it is extremely important that each pin in the connector be wired correctly. Make sure the 48 V DC from the MPS-488HP is wired directly (and only) to the 48 V DC pins on the loudspeaker connector, and that the polarity is observed (negative to negative, positive to positive) to avoid damage to the loudspeaker.
