CRYSTAL ACOUSTICS THX ULTRA2 CERTIFIED SPEAKERS

5.6 THX Subwoofer installation guide

The following instructions are for THX Ultra2 Certified as well as non-certified Dolby Digital/DTS
A/V receivers or surround processors.
1. Turn off your receiver or multi-channel amplifier and make sure the subwoofer is off
2. Use a high quality shielded interconnect with RCA connectors to link the subwoofer to the
output of your receiver or multi-channel amplifier
3. Set the Operational Mode switch on your TX-12SUB to the THX position
4. Set the phase switch to 0° (Normal)
5. Turn on your system and the subwoofer
6. Navigate to the Speaker Setup menu of your receiver or processor to calibrate channel level
and size of your front, centre and surround speakers
7. Set your main and surround speakers to "Small" on your receiver or processor
8. Set the roll off point to the following:
• 80Hz (THX standard) for THX Ultra2 or Select loudspeakers or other speakers of bigger size
• 120-150Hz for other small speakers (Crystal Acoustics Plasma, SmArt System and Bipolar series)
• The higher the crossover, the better the power handling of your main speakers
9. Change the Phase Control of your THX subwoofer between 0° and 180° positions
10. Listen to music with prominent bass
11. Stay with the switch position that produces the fullest, deepest and tightest bass in your
listening area
12. Use the pink noise test signal of your receiver, processor or test DVD
13. Take a seat at the main listening and viewing position
14. Use a SPL meter (C scale, slow) and calibrate the output sound level of each channel (fronts,
centre, surrounds) plus your subwoofer, so that all outputs levels are equal
15. When using a single TX-12SUB subwoofer, you must increase the subwoofer output level of your
receiver or processor by 12dB to get the proper bass levels to meet THX standards
16. Connection of multiple subwoofers to a receiver or processor with only one SUB/LFE output
can be accomplished with Y-adapters (RCA male to two RCA female connectors)
17. Using the Crystal Acoustics Wireless Transmitter-Receiver solution you can easily connect your
subwoofer with the minimum of fuss and free from the clutter of speaker wires
