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 INTRODUCING THE STELLA-4 Make sure to read these operating instructions in their entirety before configuring a loudspeaker system with Stella-4s. In particular, pay close attention to material related to safety issues. The Stella-4 is a self-powered loudspeaker designed primarily for installations with the LCS Constellation system.
CHAPTER 1: INTRODUCTION The Stella-4 can be easily mounted on ceilings or walls with mounting accessories available from Meyer Sound and third-party manufacturers. Stella-4 Loudspeaker Mounted with MAMB Adjustable Bracket The Stella-4C offers the same sonic capabilities as the Stella-4 in a package specifically designed for flushmount ceiling and wall applications, where it mounts in standard 8-inch backcans from third-party manufacturers.
CHAPTER 2: CONNECTING THE STELLA-4 THE STELLA-4 CONNECTOR Loudspeaker Wiring with Belden 1502R Cable The Stella-4 receives DC power and balanced audio from the five-pin Phoenix connector on its back 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 Stella-4 back panel. The connector accepts conductors up to 12 AWG (American Wire Gauge) or 2.5 mm2.
CHAPTER 2: CONNECTING THE STELLA-4 AC Power The Stella-188 Back Panel The Stella-188 is powered on and off with the AC Power switch. The Stella-188 back panel includes an AC connector, an Audio Input connector for receiving up to eight channels of source audio, and eight Channel Output connectors that can deliver DC power and balanced audio to up to 16 Stella-4 loudspeakers.
STELLA-4 OPERATING INSTRUCTIONS You can use the following tables as a guide for selecting cable gauges and circuit breaker ratings for the system’s operating voltage. Current Draw for Stella-188 with Eight Stella-4s Current Draw (Eight Stella-4s) Pay close attention to these important electrical and safety issues. ■ 115 V AC 230 V AC 100 V AC 0.583 A rms 0.550 A rms 0.659 A rms Maximum Long-Term Continuous Current 2.2 A rms 1.2 A rms 2.5 A rms Burst Current 2.4 A rms 1.4 A rms 2.
CHAPTER 2: CONNECTING THE STELLA-4 The Audio Input connector requires either a 25-pin D-sub to 8-channel audio snake, or 25-pin D-sub to D-sub cable for connecting directly to audio processors. Channel Outputs (1–8) Meyer Sound manufacturers the following cables that can be used with the Stella-188 Audio Input connector (for more information, contact Meyer Sound). ■ D-sub male to D-sub male cable, 0.5 meters (PN 28.167.012.01) ■ D-sub male to D-sub male cable, 1 meter (PN 28.167.012.
STELLA-4 OPERATING INSTRUCTIONS Cable Lengths and Cable Gauges for Stella-4s When connecting a single Stella-4 to a Stella-188 Channel Output, you can use cable lengths of up to 300 feet with only 1 dB of peak SPL loss, using 18 AWG wire. When connecting two Stella-4s, equivalent lengths are possible with heavier wire gauges (see Table 3 and Table 4). CONNECTING STELLA-4S TO THE STELLA-188 Audio sources Table 3: Stella-4 Loudspeaker Cable Lengths (AWG) Cable Gauge Resistance (Ω/ft) Approximate Max.
CHAPTER 2: CONNECTING THE STELLA-4 To connect two Stella-4s to a single Stella-188 Channel Output, daisy-chain the cable of the first Stella-4 to the second Stella-4. Wire the cable connector plugged into the first Stella-4 with both the cable connected to the Stella-188 and the cable connected to the second Stella-4. NOTE: When connecting two Stella-4s to a single Stella-188 Channel Output, the maximum cable length is reduced by half.
CHAPTER 3: STELLA-4 MOUNTING OPTIONS IMPORTANT SAFETY CONSIDERATIONS MOUNTING THE STELLA-4 When installing Meyer Sound loudspeakers, the following precautions should always be observed: The Stella-4 can be mounted with the following bracketing options: ■ All Meyer Sound products must be used in accordance with local, state, federal, and industry regulations. It is the owner's and user's responsibility to evaluate the reliability of any rigging method for their application.
CHAPTER 3: STELLA-4 MOUNTING OPTIONS Mounting the Stella-4 with an MMB Bracket To mount the Stella-4 with an MMB bracket: 1. Separate the MMB wall plate from the MMB loudspeaker plate by unscrewing the thumbscrew. 2. Mount the MMB wall plate to the wall with one of the following options. Position the wall plate so its hinges are pointing up. ■ ■ Mount directly to the wall surface using screws in the four corner holes. Use fastening hardware appropriate for the mounting surface.
STELLA-4 OPERATING INSTRUCTIONS 4. Attach the pivot plate assembly to the wall plate using the screw and washers previously removed. Tighten the screw. MOUNTING THE STELLA-4C The Stella-4C can be mounted flush in ceilings and walls with any standard 8-inch backcan (such as the Atlas BMT95-8 and Lowell CP-84 and XCP-84) with a minimum depth of 4 inches. Installing the Stella-4C in a Backcan To install the Stella-4C into a standard 8-inch backcan: 1.
