Your Definitive Technology ProSub 600 subwoofer is equipped with a full comple-
ment of operating controls to ensure complete flexibility and maximum performance in
any installation. Most of them basically are the “set and forget” type, although occa-
sionally certain controls will require minor adjustments.
Level Control
This control varies how loud the subwoofer plays. Please follow the level control
suggestions in hook-up section.
Low-Pass Filter
Your subwoofer’s back panel features a continuously variable low-pass filter. If
you are using the low level LFE input, you will normally turn the Low-Pass Filter
Control all the way up to 150. If you are using Method 1 System Hook-up you will
normally set the low-pass filter to between 10 and 12 o’clock. Always remember the
exact setting will vary with different rooms and different positions as well as personal
taste, so we encourage you to experiment.

Troubleshooting
If you experience any difficulties with your subwoofer, try the suggestions described
below. If you are still having problems, please consult your Definitive Technology
Authorized Dealer for assistance.
1. Make sure all your system interconnects and power cords are solidly in
their place.
2. Should you experience any level of ground hum or noise, try plugging the sub-
woofer into the same circuit as your amplifier. Please note that some cable TV
hookups induce hum into the whole system and require a special isolation device.
Please consult your dealer.
3. The system is provided with sophisticated internal protection circuitry. If for some
reason the protection circuitry is tripped, please turn down your system’s volume
and wait five minutes before trying the system again. If the amplifier should over-
heat, the system will turn itself off until the amplifier cools and resets.
4. Check to be sure that your power cord has not been damaged.
5. Check that no foreign objects or liquid has entered the cabinet.
6. If you cannot get your subwoofer to turn on or if no sound comes out and you’re
sure the system is set up properly, please bring the subwoofer to your Defi
nitive
Technology Authorized Dealer for assistance.
