High Level Speaker Wire Connections
Your Definitive Technology ProSub subwoofer can also be hooked up
via high level connections. In this situation, you have the option of running
your main speakers "full range" or rolling off the low end by using the high
pass filter built into the subwoofer. For high level wiring, your interconnects
are simply equal distance lengths of high quality speaker cable.
To hook up your ProSub subwoofer via the high level connections,
simply run speaker cable from the right channel high level connector on
the subwoofer to the right channel speaker connector of your receiver or
amplifier. Repeat this process for the left channel. Please take care that
the red ("+") terminal on the subwoofer is connected to the red ("+")
terminal on your receiver or amplifier, and that the black ("-") terminal
on your receiver or amplifier is connected to the black ("-") terminal on
the subwoofer. This will ensure absolute phase throughout your system.
Your main speakers can now be connected in one of two ways. If you
wish to utilize the high pass filter built into your subwoofer, simply
connect your main speakers to the high level out terminals on the
subwoofer. Again, take care to make red to red ("+") and black to black
("-") terminal connections. This connection will provide a smoothly
contoured roll-off of the low frequencies going to your main speakers.
We recommend this hook-up (wiring the main speakers through the
crossover in the subwoofer) when using ProMonitors. For more overall
