Placing The Subwoofer - JBL SUB80P Bedienungsanleitung

Line-Level L/R In connectors: When you're connecting the subwoofer to the preamp or subwoofer outputs of a receiver/processor that does
not have its own low-pass crossover network, use both Line-Level L/R In connectors. You must also set the Input Mode switch in the "Normal"
position to enable the subwoofer's internal low-pass crossover. If your receiver/processor has only one subwoofer output, you can use either the L
or R connector.
Wireless Code switch: This switch selects between four different channels for the wireless subwoofer signal.
IMPORTANT: Be sure to set the subwoofer's Wireless Code switch to the same channel that you set the transmitter module's
Wireless Code switch. See Wireless Code Switches, on page 7, for more information.
Power switch: Set this switch in the "On" position to turn the subwoofer on. The subwoofer will then be either on or in the standby mode,
depending on the setting of the Power On Mode switch.
Power Cord (non-detachable): After you have made and verified all the connections described in this manual, plug this cord into an active,
unswitched electrical outlet for proper operation of the subwoofer. DO NOT plug this cord into the accessory outlets found in some audio
components.
TRANSMITTER UNIT
Power connector: Plug the transmitter power supply into this connector and into a working AC outlet.
Wireless Code switch: This switch selects between four different channels for the wireless signal.
IMPORTANT: Be sure to set the transmitter unit's Wireless Code switch to the same channel that you set the subwoofer's Wireless
Code switch. See Wireless Code Settings, on page 7, for more information.
Input connectors: Connect the supplied LFE cable from your receiver's or processor's subwoofer output to either of the transmitter unit's Input
connectors.

The performance of a subwoofer is directly related to its placement in the listening room and its physical position relative to the other speakers in
the system.
While it is true that in general our ears do not hear directional sounds at the low frequencies where subwoofers operate, when installing a
subwoofer within the limited confines of a room, the reflections, standing waves and absorptions generated within the room will strongly influence
the performance of any subwoofer system. As a result, the specific location of the subwoofer in the room does become important to the amount
and quality of bass that is produced.
For example, placing the subwoofer next to a wall generally will increase the amount of bass in the room; placing it in a corner (1) generally
will maximize amount of bass in the room. However, corner placement can also increase the destructive effect of standing waves on bass
performance. This effect can vary depending on the listening position – some listening positions may yield very good results while others may have
far too much (or too little) bass at certain frequencies.
In many rooms, placing the subwoofer along the same plane as the left and right speakers (2) can produce the best integration between the sound
of the subwoofer and that of the left and right speakers. In some rooms, the best performance could even result from placing the subwoofer
behind the listening position (3).
We strongly recommend that you experiment with placement before choosing a final location for your subwoofer. One way you can determine the
best location for the subwoofer is by temporarily placing it in the listening position and playing music with strong bass content. Move around to
various locations in the room while the system is playing (putting your ears where the subwoofer would be placed), and listen until you find the
location where the bass performance is best. Place the subwoofer in that location.
