LEVEL CONTROL
The electronic sensitivity and gain in all full-range JF

models is fixed by design. There are
no adjustable, input level controls. This means that whenever the loudspeaker is connected to the
AC mains and provided with audio signal the output level is always controlled externally to the
loudspeaker. This way, there is no question about a misadjusted level control on the loudspeaker.
This also largely prevents overdriving the equipment directly upstream of the loudspeakers.
The sensitivity is designed to match with a wide range of professional line-level audio equipment
with nominal operating levels of 0 dBu (= 0.775 V). Consumer equipment has nominal operating
levels of 8 dB to 10 dB below 0 dBu. If used with the latter equipment, it may not be possible to
reach full output before clipping upstream equipment. In such cases, there are 3rd party devices
available that can be inserted into the signal path to match the impedance and level between
consumer and professional equipment.

AC MAINS SUPPLY
WARNING
: Read all instruction and cautionary notes concerning
electrical power in the “EAW Loudspeaker Manual”.
DANGER:
Ensure that the AC mains voltage matches the voltage rating
listed on the loudspeaker next to the AC Mains connector. DO NOT APPLY
230 V MAINS POWER IF THE VOLTAGE RATING ON THE
LOUDSPEAKER IS 115 V. IMMEDIATE AND CATASTROPHIC
DAMAGE TO THE LOUDSPEAKER WILL RESULT AND MAY
CAUSE A FIRE HAZARD, SERIOUS PERSONAL INJURY, OR
DEATH.

SECTEUR
ATTENTION:
Lisez toutes les instructions et notes de sécurité sur l'alimentation secteur, dans
le mode d'emploi de l'enceinte EAW.
DANGER:
Vérifiez la tension secteur de l'enceinte, sérigraphiée à côté de l'embase secteur de
l'enceinte. NE PAS APPLIQUER UNE TENSION SECTEUR DE 230 V SI L'ENCEINTE
ESTDE 115 V. LES DOMMAGES À L'ENCEINTE SERAIENT IMMÉDIATS

6.3.1 ALIMENTAZIONE
AC
ATTENZIONE:
Leggere tutte le istruzioni e le avvertene riguardanti l'alimentazione elettrica,
incluse nel Manuale EAW Loudspeaker.
PERICOLO:
Assicurarsi che il voltaggio dell'alimentazione utilizzata nell'area in cui si intende
utilizzare il diffusore, corrisponda al voltaggio riportato nel pannello posterore del diffusore,
vicino alla connessione di alimentazione AC. NON UTILIZZARE UN VOLTAGGIO DI 230
VSE NEL DIFFUSORE VIENE INDICATO UN VOLTAGGIO DI 115 V. IL DANNO PER
ILDIFFUSORE SAREBBE IMMEDIATO E MOLTO SERIO, E POTREBBE
CAUSAREINCENDI, DANNI FISICIALLE PERSONE E LA MORTE.
