1. Power Indicator. This light is illuminated blue when the subwoofer is turned on and
playing. It illuminates red when the subwoofer is in on, but in Standby mode.
2. Low-Level Inputs. These connect with RCA type cables from the line-level outputs of
your receiver or preamp. Here are two examples: If your processor or receiver has a
single subwoofer output, connect it to the subwoofer's LFE input connector (see page 8).
If your processor or receiver has stereo line-level output, connect it to the subwoofer's
red and white Low Level "IN" connectors.
3. Low-Level Outputs. These connect with RCA type cables to daisy-chain additional
subwoofers or powered speakers. These outputs are pass-thru, meaning they will pass
through the same audio signal that is fed into the Low-Level inputs to the Low-Level
outputs.
4.
USB Connector. The USB connector is used to power the optional subwoofer wireless
receiver. Do not plug in other USB devices into this port as it may damage the subwoofer
or the device. Refer to the wireless receiver installation instructions for more details.
5. Power Rocker Switch. Press the top this rocker switch to turn the subwoofer's master
power On. The subwoofer has an automatics signal-detection circuit. After approximately
ten minutes with no signal, the subwoofer will go into its quiet standby mode.
The presence of an audio signal will turn it back on. The signal-detection timeout period
can be adjusted in the companion smartphone app. Normally you can leave the switch
on, and let the subwoofer turn on when a signal is present, or turn off when it's not. At
night (or if you go out,or on vacation), you can press the bottom of the power switch to
turn the subwoofer off.
6. AC Line Fuse. The subwoofer is supplied with a conservative slow-blow type fuse to
protect the electronics. If this fuse fails, replace it with the exact same type and current
rating for your local AC voltage, as marked on the control panel near the fuse holder.
7. IEC Power Connector. The subwoofer comes with a detachable line cord that attaches
here. Make sure it is firmly pushed into place. Connect the other end to an AC outlet that
is properly configured for the type of plug and has the correct voltage for your model.
NOTE: Always unplug the power cord from your AC outlet before
removing the fuse. To replace or inspect the fuse, use a small flathead
screwdriver to gently pry out the fuse carrier and fuse.
8. Voltage Selection Switch. This switch is used to select the compatible electrical voltage
for the location in which you're installing the subwoofer. Please check with your local
electrical requirements before making changes to this setting.
9.
Mounting Standoffs. The mounting standoffs are used to mount the optional subwoofer
wireless receiver. Refer to the wireless receiver installation instructions for more details.
