EAW NT56 Portable Speaker User Manual


 
Audiosignalverbindung
Schließen Sie das Audiosignal am Lautsprecher an, BEVOR Sie den Lautsprecher an das
Stromnetz anschließen.
WARNUNG: Stellen Sie das Ausgagssignal der Signalquelle (z.B. Masterregler eines
Mischpultes) auf den kleinsten Wert, bevor Sie den NT Lautsprecher an das Stromnetz
anschließen. Da dieses Signal zum Lautsprecher geschickt wird, könnten bei starkem
Quellsignal extrem bzw. schädliche Asgangspegel von der Box produziert werden, wenn
diese mit Netzstrom versorgt wird.
6.1.1 Input Panel
The audio input connection to the loudspeaker can be
made to either the female INPUT or male LOOP
connector on the rear of the loudspeaker. Normaly, the
female connector is used for the input signal. Connect
the output from your signal source (mixing console,
microphone preamp, or other line-level source) to either
XLR-3 connector. This is an electronically balanced input
designed to be connected to a balanced signal source.

6.1.2 Loop Connector
The Loop connector is hard-wired to the Input connector and thus carries the identical signal.
This connector is used to "daisy-chain"the input signal to multiple NT loudspeakers and NT
subwoofers. Because the signal processing, including the crossover, is built in, full-range
loudspeakers and subwoofers may be daisy-chained together from a single signal source.
NOTE: To avoid potential interference, do not leave an un-terminated cable attached to
either the Input or the Loop connector.
6.2 System GAIN
6.2.1 Level Control
The electronic sensitivity and gain in all full-range NT 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.
