ELAC SUB 2050 - Page 21

1 SPEAKER LEVEL IN
These are input sockets for connecting the ELAC subwoofer to the loudspeaker outputs of a power amplier or surround receiver.
The bass frequencies of the incoming audio signals at the “LINE IN” and “SPEAKER LEVEL IN” sockets are combined and reproduced via the
subwoofer.
The input circuit is a symmetrically oating design that allows the ELAC subwoofer to function like a passive speaker. This means that
ampliers 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 independent of frequency. A 2 x 2.5 mm² cable is normally recommended. Please insert the wires carefully into the
terminals. Short circuits caused by protruding wires touching the adjacent wire or the housing must be avoided at all costs
2 LINE IN L / LFE - R
These RCA input sockets are used to connect the ELAC Subwoofer to the stereo line output of a pre-amplier or the “BASS” / “SUB OUT” / “LFE”
output of a surround-sound amplier/surround receiver. A standard mono line-level cable tted with RCA plugs is used for these connections.
These plugs should not be plugged in or pulled out during operation.
3 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.
Tip: If you do not wish to use ELAC wireless technology, you can also use the special “ELAC Wireless Interface Socket”, for example, to charge
your cell phone or mp3 player (the subwoofer must be switched on and the operating status LED must light up). Simply connect the charging
cable for your device to this USB socket.
ELAC accepts no liability for any damage caused to your device.
4 AC Power Socket
Please insert the IEC plug at the end of the supplied mains power cable here.
5 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.
6 POWER (ON / OFF)
The device is switched on and o 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 o 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 ow even in stand-by mode (indicated by the white LED on the
front).
7 Service Connection
This socket is provided for service purposes and is not used for normal operation.
