ELAC SUB 2090 Bedienungsanleitung Seite 21

1 SPEAKER LEVEL IN
These are input sockets for connecting the ELAC subwoofer to the loudspeaker outputs of a power ampli-fier or surround receiver.
The bass frequencies of the incoming audio signals are combined and reproduced via the subwoofer.
The input circuit is a symmetrically floating design that allows the ELAC subwoofer to function like a pas-sive speaker. This means that
amplifiers with bridge circuits can be safely connected. Compared with passive loudspeakers, however, the current or power drawn is much
lower (around 1/40th) and is inde-pendent of frequency. Consequently, there are no benefits to be gained from using especially thick cables or
' e soteric' cable designs. A 2 x 2.5 mm² cable is normally recommended. Please insert the wires careful-ly into the terminals. Short circuits caused
by protruding wires touching the adjacent wire or the housing must be avoided at all costs.
2 BALANCED LEVEL IN L / BALANCED LEVEL IN R
The XLR connectors offer the possibility to connect the ELAC subwoofer to High-End audio equipment. The advantage of this type of
connection is the symmetrical signal transmission and thus the vast immunity against disturbances. If your source offers symmetrical outputs
this type of connection should be preferrably used instead of the unsymmetrical RCA connection.
3 LINE IN L/LFE - R
These RCA input sockets are used to connect the ELAC Subwoofer to the stereo line output of a pre-amplifier or the "BASS" / "SUB OUT" / "LFE"
output of a surround-sound amplifier/surround receiver. A standard mono line-level cable fitted with RCA plugs is used for these connections.
These plugs should not be plugged in or pulled out during operation.
4 ELAC WIRELESS INTERFACE SOCKET
Input socket for connecting the optional ELAC wireless receiver dongle. With the help of this dongle, you can add wireless connectivity to your
active subwoofer. By using ELAC wireless technology, you can avoid laying RCA cables to the subwoofer.
5 AC Power Socket
Please insert the IEC plug at the end of the supplied mains power cable here.
6 Fuse Holder
Should a replacement fuse be required, only fuses with the rating printed on the rear of the loudspeaker may be used.
ATTENTION: The ELAC subwoofer is only fully disconnected (isolated) from the mains supply when the power plug is pulled out! Always
disconnect the subwoofer from the mains before re-placing the fuse.
7 POWER (ON / OFF)
The device is switched on and off by the power switch.
After the audio cables and the power supply have been connected using the power cable provided, you can turn on the mains switch. If the
device will not be used for an extended period, it should be switched off to avoid unnecessary power consumption.
ATTENTION: The ELAC subwoofer is only fully disconnected (isolated) from the mains supply when the power plug is pulled out! When the
power plug is plugged in and the power switch is on, there is a residual current flow even in stand-by mode (indicated by the white LED on the
front).
8 Service Connection
This socket is provided for service purposes and is not used for normal operation.
