In the Edit Loudspeaker Inventory dialog box, click in the Product column and select the HMS loudspeaker model connected to each MPS-488HP channel output. ■ Single-channel HMS loudspeakers (HMS-5, HMS-10, and HMS-12) occupy a single channel output. ■ Dual-channel HMS-15 loudspeakers automatically occupy two channel outputs.
CHAPTER 4: HMS MOUNTING OPTIONS IMPORTANT SAFETY CONSIDERATIONS! When mounting Meyer Sound loudspeakers, the following precautions should always be observed: ■ All Meyer Sound products must be used in accordance wall surface. Verify that the building’s structure and the with local, state, federal, and industry regulations. It is the anchors used for the installation will safely support the owner’s and user’s responsibility to evaluate the reliability...

CHAPTER 5: REMOVING HMS GRILLE FRAMES If a cinema installation requires it, HMS grille frames can be easily removed. Grille frames for the HMS-5 and HMS-10 are removed by simply unsnapping the corner treeloks and removing the grille. Grille frames for the HMS-12 and HMS-15 include an L-bracket securing them to the bottom of the cabinet, for safety reasons, that must be removed before the grille can be detached.

APPENDIX B: ASSEMBLING LOUDSPEAKER CABLES CAUTION: When wiring 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 loudspeaker connector, and that the polarity is observed (negative to negative, positive to positive) to avoid damage to the loud- speaker.
Page 26
APPENDIX B: ASSEMBLING LOUDSPEAKER CABLES 3. Secure the conductors by tightening the five screws in the Phoenix cable mount connector. Screws should be torqued to 5–6 Nm (4.4–5.3 in-lbs). Tighten screws CAUTION: Screws should not be inserted into the Phoenix connector while the connector rests in a mating plug. Doing so will damage the contacts.
