IMPORTANT SAFETY INSTRUCTIONS

1. Read these instructions.

2. Keep these instructions.

3. Heed all warnings.

4. Follow all instructions.

5. Do not use this loudspeaker near water.

6. Clean only with dry cloth.

7. Do not block any ventilation openings. Install in accor­dance with Meyer Sound's installation instructions.

8. Do not install near any heat sources such as radiators,
heat registers, stoves, or other apparatus that produce
heat.

9. Do not defeat the safety purpose of the grounding-type
plug. A grounding type plug has two blades and a third
grounding prong. The third prong is provided for your
safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete
outlet.

Meyer Sound, or sold with the loudspeaker. Handles are
for carrying only.

13.Unplug this loudspeaker during lightning storms or when
unused for long periods of time.

14.Refer all servicing to qualified service personnel. Servic­ing is required when the loudspeaker has been damaged
in any way, such as when the power-supply cord or plug
has been damaged; liquid has been spilled or objects
have fallen into the loudspeaker; rain or moisture has
entered the loudspeaker; the loudspeaker has been
dropped; or when for undetermined reasons the loud­speaker does not operate normally.

CAUTION: To reduce the risk of electric shock,

!

do not expose this loudspeaker to rain or mois­ture. Do not install the loudspeaker in wet or humid
locations without using weather protection equip­ment from Meyer Sound.

SAFETY SUMMARY

English

■ To reduce the risk of electric shock, dis-

connect 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.

■ Do not install the loudspeaker in wet or

humid locations without using weather
protection equipment from Meyer
Sound.

■ Do not allow water or any foreign object

to get inside the loudspeaker. Do not
put objects containing liquid on or near
the unit.

■ To reduce the risk of overheating the

loudspeaker, avoid exposing it to direct
sunlight. Do not install the unit near
heat-emitting appliances, such as a
room heater or stove.

■ This loudspeaker contains potentially

hazardous voltages. Do not attempt to
disassemble the unit. The unit contains
no user-serviceable parts. Repairs
should be performed only by factory­trained service personnel.

Français

■ Pour réduire le risque d’électrocution,

débrancher la prise principale de l’haut­parleur, avant d’installer le câble d’inter­face allant à l’audio. Ne rebrancher le
bloc d’alimentation qu’après avoir
effectué toutes les connections.

■ Branchez l’haut-parleur dans une prise

de courant à 3 dérivations (deux pôles
et la terre). Cette prise doit être munie
d’une protection adéquate (fusible ou
coupe-circuit). Le branchement dans
tout autre genre de prise pourrait
entraîner un risque d’électrocution et
peut constituer une infraction à la régle­mentation locale concernant les instal­lations électriques.

■ Ne pas installer l’haut-parleur dans un

endroit où il y a de l’eau ou une humid­ité excessive.

■ Ne pas laisser de l’eau ou tout objet

pénétrer dans l’haut-parleur. Ne pas
placer de r´cipients contenant un liquide
sur cet appareil, ni à proximité de celui­ci.

■ Pour éviter une surchauffe de l’haut-

parleur, conserver-la à l’abri du soleil.
Ne pas installer à proximité d’appareils
dégageant de la chaleur tels que radia­teurs ou appareils de chauffage.

■ Ce haut-parleur contient des circuits

haute tension présentant un danger. Ne
jamais essayer de le démonter. Il n’y a
aucun composant qui puisse être
réparé par l’utilisateur. Toutes les répa­rations doivent être effectuées par du
personnel qualifié et agréé par le con­structeur.

Deutsch

■ Um die Gefahr eines elektrischen

Schlages auf ein Minimum zu
reduzieren, den Lautsprecher vom
Stromnetz trennen, bevor ggf. ein
Audio-Schnittstellensignalkabel ange­schlossen wird. Das Netzkabel erst
nach Herstellung aller Signalverbindun­gen wieder einstecken.

■ Der Lautsprecher an eine geerdete

zweipolige Dreiphasen-Netzsteckdose
anschließen. Die Steckdose muß mit
einem geeigneten Abzweigschutz
(Sicherung oder Leistungsschalter) ver­bunden sein. Der Anschluß der unter­brechungsfreien Stromversorgung an
einen anderen Steckdosentyp kann zu
Stromschlägen führen und gegen die
örtlichen Vorschriften verstoßen.

■ Der Lautsprecher nicht an einem Ort

aufstellen, an dem sie mit Wasser oder
übermäßig hoher Luftfeuchtigkeit in
Berührung kommen könnte.

■ Darauf achten, daß weder Wasser noch

Fremdkörper in das Innere den
Lautsprecher eindringen. Keine
Objekte, die Flüssigkeit enthalten, auf
oder neben die unterbrechungsfreie
Stromversorgung stellen.

■ Um ein Überhitzen dem Lautsprecher

zu verhindern, das Gerät vor direkter
Sonneneinstrahlung fernhalten und
nicht in der Nähe von wärmeabstrahl­enden

■ Haushaltsgeräten (z.B. Heizgerät oder

Herd) aufstellen.

■ Im Inneren diesem Lautsprecher herr-

schen potentiell gefährliche Spannun­gen. Nicht versuchen, das Gerät zu
öffnen. Es enthält keine vom Benutzer
reparierbaren Teile. Reparaturen dürfen
nur von ausgebildetem Kundenienst­personal durchgeführt werden.

Español

■ Para reducir el riesgo de descarga eléc-

trica, desconecte de la red de voltaje el
altoparlante antes de instalar el cable
de señal de audio. Vuelva a conectar la
alimentacion de voltaje una vez efectu­adas todas las interconexiones de
señalizacion de audio.

■ Conecte el altoparlante a un tomacorri-

ente bipolar y trifilar con neutro de
puesta a tierra. El tomacorriente debe
estar conectado a la protección de deri­vación apropiada (ya sea un fusible o un
disyuntor). La conexión a cualquier otro
tipo de tomacorriente puede constituir
peligro de descarga eléctrica y violar los
códigos eléctricos locales.

■ No instale el altoparlante en lugares

donde haya agua o humedad excesiva.

■ No deje que en el altoparlante entre

agua ni ningún objeto extraño. No
ponga objetos con líquidos encima de
la unidad ni cerca de ella.

■ Para reducir el riesgo de sobrecalen-

tamiento, no exponga la unidad a los
rayos directos del sol ni la instale cerca
de artefactos que emiten calor, como
estufas o cocinas.

■ Este altoparlante contiene niveles de

voltaje peligrosos en potencia. No
intente desarmar la unidad, pues no
contiene piezas que puedan ser repar­das por el usuario. Las reparaciones
deben efectuarse únicamente por parte
del personal de mantenimiento capaci­tado en la fábrica.

INTRODUCING THE STELLA-4

The Stella-4 is a self-powered loudspeaker designed prima­rily for installations with the LCS Constellation system. Its
single 4-inch cone transducer, housed in a compact alumi­num die cast enclosure, delivers an impressive frequency
range of 100 Hz to 22 kHz and a maximum peak SPL of
108 dB (93 dB average) at one meter. Containing onboard
amplification and processing, the Stella-4 exhibits the same
high intelligibility and flat frequency and phase response
characteristic of Meyer Sound loudspeakers.

Stella-4 Loudspeaker

The Stella-4 receives balanced audio and DC power from a
five-pin Phoenix-style connector on its back panel. Meyer
Sound's patented Iso-Input™ transformer-isolated differen­tial inputs yield a high common-mode signal rejection ratio
(CMRR). Because the Stella-4 has been optimized to toler­ate voltage drops of up to 30% it can accommodate light­gauge cables and long cable runs.

Stella-188 Power Supply

The required method for delivering DC power and balanced
audio to the Stella-4 is with the Stella-188 Power Supply.
The single-space rack unit can accommodate up to 16
Stella-4s. The Stella-188 accepts balanced audio through its
25-pin D-sub Audio Input connector and outputs the audio,
along with 18 V of DC power, to its five-pin Phoenix Channel
Output connectors. The front panel of the Stella-188 has
LEDs for monitoring voltage output and connectivity to the
Stella-4s.

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. The
Stella-4C is housed in an aluminum die cast enclosure with
a heatsink on the back.
