Speaker Connections
Once you’ve found a place in your room, the next step is connecting the
Pro 12 to your existing system. Listed below you will find 3 options.
Option 1: Connecting the Pro 12 using the stereo Low Level preamp/processor
inputs.
If using Left/Right output jacks from the preamp, the internal circuit module of the
Pro 12 will sum the two channels together. When using the left and right low level
inputs on the subwoofer, the internal crossover of the subwoofer is being used. The
crossover frequency and level will be controlled by the appropriately labeled
controls on the rear panel of the sub.
The Left/Right line output jacks can be used to send a crossed over high frequency
signal.
NOTE: if using the low-level inputs, we suggest using cables that are no
longer than 5 meters. Longer lengths of RCA cable can result in greater
noise and attenuation of the signal.
