CUSTOM FEATURES
POLARITY REVERSE
In situations where the CVXL-118s or CVXL-218s is not optimally located, a polarity reverse switch is provided
which inverts the audio signal by 180 degrees and can improve low frequency performance. In certain situations,
the location of the subwoofer may be out of phase with the full-range speakers. By reversing the polarity of the
subwoofer, the phase will match the full-range with the benefit of not having to relocate the subwoofer.
CARDIOID MODE
When using multiple subwoofers in stacks or side by side, cardioid sub units can be turned backward to face the
stage and switched to CARDIOID MODE. This will reduce the volume of the subwoofers for the performers on
stage, while still projecting good low frequency coverage toward the audience. This is particularly beneficial when
the subwoofers are placed relatively close to performers in high volume level settings.
CROSSOVER FREQUENCY
This switch selects the crossover frequency of two simultaneous filters; the low pass filter for the subwoofer and
the high pass filter of the THRU 1 & 2 outputs. For smaller setups, it is recommended to connect the source output
(such as a mixing board) to the subwoofer INPUT 1 and INPUT 2 connectors and the inputs of other powered full
range loudspeakers (such as the CVXL-112, CVXL-115, or CVXL-215) to the subwoofer THRU 1 & 2 outputs for a
more balanced and pleasing sound.
