THX subwoofers
2. INTRODUCTION
Congratulations! Your new M&K THX
®
subwoofer truly represents the state-of-the-art in subwoofer
performance. The new dimension of deep and powerful bass it provides will both thrill and excite you.
We strongly encourage you to read this owner's manual, as there is a great deal of information
provided here to help you get the best possible performance.
If you have any questions about your subwoofer, please contact your M&K Home THX
Audio dealer,
or call the M&K factory directly at (310) 204-2854, from 8:30 AM to 5:00 PM Pacific Time. We will be
more than happy to help you with any question, no matter how simple or complex it may be.
For more details on the installation and calibration of your Home THX Audio system, please refer
to the THX Installation & Operation Manual.
THIS OWNER'S MANUAL HAS TWO SETS OF SET-UP INSTRUCTIONS.
ONE SET IS FOR USING THE SUBWOOFER WITH A THX CONTROLLER.
THE OTHER SET IS FOR USE WITH NON-THX PROCESSORS.
To operate it with a THX controller, see Section 4 below.
To use it with a non-THX controller, see Section 6 (page 7).
3. WHERE TO PLACE YOUR SUBWOOFER
Your subwoofer will deliver excellent performance located virtually anywhere in your room. Unless
you are next to the subwoofer, you will not hear it as a separate source of sound. In fact, its deep bass
will appear to come from your other speakers. Therefore, there is no
need
to place your subwoofer
either between your Satellite or L/C/R speakers or in any specific location in the room.
You can significantly improve and fine-tune your subwoofer's performance by experimenting with
its placement in the room. For more detailed placement information, please see Section 8 (page 12).
Your subwoofer is magnetically shielded, so you can locate it close to a television without picture
distortion occurring from magnetic deflection of the TV's electron beam.
Wherever you put the subwoofer, you must allow room for ventilation of its heatsink and backplate.
The subwoofer's power amplifier is mounted on the backplate, and it generates heat. Therefore:
1. Do not place the subwoofer against a wall. Leave at least 3 inches clearance for the heatsink.
2. Do not place the subwoofer close to baseboard heaters or forced air heating outlets.
DO NOT PLUG THE SUBWOOFER INTO AN AC OUTLET
UNTIL ALL SYSTEM WIRING IS COMPLETE
4. OPERATION WITH THX COMPONENTS
CONNECTING THE SUBWOOFER TO A THX CONTROLLER
The "INPUT" RCA terminals on the subwoofer connect it to the outputs of your THX controller. All
of the input connections and controls for the subwoofer are located on its large metal backplate, which
can be found on the back panel of the subwoofer cabinet.
To connect the subwoofer, run a shielded RCA - RCA interconnect cable from the SUBWOOFER
