THOR SUBWOOFER
8
9
MODEL: 10.6
CAUTION
1. This subwoofer has electronics built into the cabinet and must be properly
ventilated.
2. Do not place the rear of cabinet against a wall, you must allow room for adequate
ventilation of the amplifier (at least 2 inches).
3. Do not place the subwoofer next to heat sources, such as heaters or radiators, etc.
4. Do not place the subwoofer near sources of excessive moisture, such as evaporative
coolers, humidifiers, etc.
5. The power cord should be routed in such a way that it will not be walked on, pinched,
cut, or compressed in any way that could result in damaging the insulation or wire.
Damage to the power cord may result in a shock or fire hazard.
Connections
All connections for the subwoofer are located on the rear of the unit. Whether you choose
the LFE (Low Frequency Effects) coaxial, Left & Right coaxial, XLR-input or Speaker Level
input the subwoofer is auto selecting the one input where there is signal.
HOME THEATER SYSTEM
Utilizing this method, the receiver or processor is the main control center for the system
and it provides all the bass management (e.g. sending the low frequency signals from the
satellite speaker channels & LFE for movies, to the subwoofer), and it provides a low-pass
filtered signal (bass information only) to the subwoofer.
Most home theater receivers/processors have at least 1 unbalanced RCA “SUBWOOFER”
output jack, some models has two . For this type of equipment, connect a single high quality
cable from your receiver’s “SUBWOOFER” output jack to the subwoofer’s input marked
with as “LFE”
If your receiver or processor has multiple subwoofer outputs, you may have additional
connection options. Consult the owner’s manual for your receiver/processor to verify if
these outputs are all the same.
RECEIVER/PRE-AMP WITH INTERNAL CROSSOVER
• By connecting to “LFE” input, the internal crossover filter is now by-passed
• The frequency control knob has no effect when using the “LFE” input.
• Adjust the “VOLUME” control knob to pointing upwards, 12 o’clock.
• Set the “PHASE” to “0”
MUSIC SYSTEM
Utilizing this method, the preamp provides a full range signal from both left & right audio
channels to the subwoofer. If your preamp does not offer an internal crossover or bass
management functions, the subwoofer’s built in controls will need to be properly set to
utilize the built in crossover and phase adjustments to blend the subwoofer output with the
satellite speakers.
This subwoofer is designed to operate from either a full range audio signal (when using the
subwoofer’s built-in crossover) or home theater (surround sound) processor/receiver with
a “SUBWOOFER” output jack and built in low-pass filter & bass management. In both cases,
proper control settings are required to achieve optimal system performance.
AMPLIFIER/PRE-AMP WITHOUT INTERNAL CROSSOVER
• By connecting to high level speaker cable inputs or RCA L & R inputs the internal
crossover is used
• Adjust the “FREQUENCY” control knob to blend the subwoofer output seamlessly with
your main speakers.
• Adjust the “VOLUME” control knob to match the output level of the subwoofer to your
main speakers
• Adjust the “PHASE” switch to smoothly blend the mid-bass output of the subwoofer to
your main speakers (read Calibration section for further information).
MULTIPLE SUBWOOFERS
When connecting multiple subwoofers, it is recommended to use the XLR pass through to
the next subwoofer. The pass through is a signal split the XLR input. It is also possible to
use the RCA signal connections,however you will need to use “Y” cables (signal splitters) to
route your amplifier/receiver/processor output to each woofer if it does not have multiple
“SUBWOOFER” output jacks or L & R variable signal output.
Calibration
INTRODUCTION
For optimal performance, you should calibrate your system to ensure proper level matching
between all speakers and the proper setting of all controls (including crossover frequency,
phase, and any channel delays your receiver/processor may offer). This procedure will vary
depending on system configuration and the information below is provided as a basic guide
to assist you. Refer to the owner’s manual for your receiver/processor for information on
performing the steps required to enter their setup mode and adjust any applicable settings.
After all connections have been made, turn on the AC power to your system, starting with
the first piece of source equipment in the signal chain (such as a CD or DVD player), then
power on any dedicated equalizer, then power on your receiver/processor/amplifier(s),
and last but not least, power on the subwoofer-/s. You will need to enter your receiver’s/
processor’s setup mode and adjust any applicable speaker settings to properly match your
system configuration
RECEIVER/PROCESSOR WITH AUTOMATED SETUP & CALIBRATION FUNCTION
After you have verified all speakers are connected and you have measured distances of
each to the listening position, perform the auto-setup routine on your receiver/processor
(if available). Many newer home theater receivers/processors combine a measurement
microphone and an automated setup routine to assist you with proper setting of speaker
levels, crossover frequency, speaker delay and phase. Consult the owner’s manual for your
receiver/processor for further instructions on how to perform the setup routine. After the
auto-setup routine is complete, verify the final settings the receiver/processor selected
to ensure there are no erroneous settings (e.g. the settings should match your system
configuration). Some settings to verify may include:
• Number of speakers (e.g. 7.1 or 5.1 system, etc.)
• Type/size of speakers (e.g. small or large front/surround and subwoofer set to yes/on)
• Crossover point should be similar for identical speakers (e.g. if your system using 3 of
the same speakers for all front channels, verify the receiver/processor selected the same
crossover point for all these channels)
