XD8s Subwoofer
AUDIO INPUT/AUDIO OUTPUT – There are two types of audio inputs. The top LEFT & RIGHT inputs are
RCA connectors for unbalanced signals, which are typically used for consumer products and musical
instruments. The bottom LEFT & RIGHT inputs are ¼" TRS (6.3mm) connectors for balanced signals,
which are typically used for professional products such as audio mixers. The OUT provides a loop‐thru
of the signals coming in on the IN. The crossover filter is active on these outputs as they are intended
for top speakers. NOTE: Home theater receivers may feature a dedicated single cable SUB OUT or LFE
connection. Simply use the LEFT input on the XD8s and set the crossover to BYPASS (as the AVR will
handle the low‐frequency filters in the audio signal).
VOLUME CONTROL – Controls volume level of subwoofer. Use to
balance the output of the subwoofer with the main speaker output.
CROSSOVER – Adjust the upper limit (HPF) of the subwoofer's
frequency response. A rule of thumb when using small speakers is
to set the switch to 120Hz (XD3). Medium size speakers are set to
100Hz (XD4). Larger size speakers are set to 80Hz (XD5). BYPASS
will disengage the filter to the subwoofer and is used with a signal
preprocessed connection (LFE). BYPASS will also disengage the
filter to the ¼" TRS and RCA OUT. NOTE: The OUT provides a loop‐
thru of the signals coming in on the IN. The crossover filter is active
on these outputs as they are intended for top speakers.
POLARITY SWITCH – Allows the signal to inverted in polairty so the
output of the subwoofer will blend in with the main speakers. Set
the POLARITY switch to "0". At the listening position, listen to the
midbass output. If it sounds weak, set POLARITY back to "180."
REMOTE CONTROL – Connects to the system remote control. CAUTION: Be sure to connect the
system remote control before powering on the subwoofer.
POWER SWITCH & POWER CORD – Set the power switch to 'ON' position when the speaker system is
ready for use. Auto‐Standby activates after 30 minutes of no activity. Standby deactivates when it detects
an input signal having an amplitude of ‐50dBu or greater. In quiet (low listening level) situations, adjust
SUB MUTE – Easy access control to mute the XD8s when a subwoofer is not
needed. The OUT connections to the top speakers are active in both ON and
OFF conditions. The ¼" and RCA OUT will see the full‐range (non‐CROSSOVER
filter signal) in SUB MUTE.
SYSTEM REMOTE VOLUME CONTROL – Master volume control for both
subwoofer and speakers connected to the XD8s OUT. To start, set the volume
at minimum level. Next, adjust the XD8s and speakers to maximum position.
Finally, adjust the System Volume control to your preferred listening level.
The light ring will be 'AMBER' during standby and is 'RED' when in an active
state. The XD8s subwoofer can function without the system volume control.
AUX IN – Use a ⅛" stereo‐mini (male to male) as the connection to a mobile
device from the XD speaker system.
