THX Certified Pre-Amp/Receivers:

If you have a THX Certified Pre-Amp/Receiver, please connect the “(THX)” input on the back

panel of the DD-15/DD-18 to the ”Sub Out” connector of the THX Pre-Amp/Receiver

. Also set

the DD-15/DD-18 to the THX Preset 5, set the system response of the subwoofer as per the

owners manual and then calibrate the THX Pre-Amp/Receiver

. This ensures that the bass

management and calibrated levels are optimized for your system.

As this is a new THX Ultra

subwoofer, if your Pre-Amp/Receiver is THX Ultra

Certified, you

may use the Boundary Gain Control in the setup menu of the THX Ultra

Pre-Amp/Receiver to

compensate for any excessive bass heard in the room if you are close to a wall.

THX Certified Ultra

Before any home theatre component can be THX Ultra2 certified, it must pass a rigorous

series of quality and performance tests. Only then can a product feature the THX Ultra

logo,

which is your guarantee that the Home Theatre products you purchase will give you superb

performance for many years to come. THX Ultra

requirements cover every aspect of the

performance of the product including power output, frequency response, distortion, etc.
