XLR OUTPUTS

features a stereo output section with two – left and right – balanced XLR connectors for connection to further subs composing
your sound system. Please note that these outputs are independent from PHASE, X-OVER, LEVEL and LOW-CUT settings, thus allowing
you to make individual adjustments for every subwoofer.
CONTROL ELEMENTS
PHASE
This switch allows you to immediately improve your subwoofer response, in case of phase problems due to environment and subs placement.
[!] Before engaging/disengaging this switch, please turn off your subwoofer(s).
X-OVER
This knob allows you to choose the best crossover frequency between your subwoofer and the other speakers. Make the initial adjustment
close to your speakers roll-off frequency.
[!] Before making any adjustment to this pot, please reduce the LEVEL knob setting.
LEVEL
This knob allows you to set the level of your subwoofer. Make the initial adjustment checking the maximum SPL stated for your
speakers, considering that your sub should have at least 3dB of SPL more. Then make adjustments using this pot, without turning off
your subwoofer(s).
LOW-CUT
This selector allows you to choose the best low-cut frequency for your subwoofer. In this way you could tune your subwoofer lower
frequencies behaviour, for example in case of bass boominess or redundancy due to environment acoustic.
[!] Before moving this selector, please reduce the LEVEL knob setting.
MAINS
POWER ON/OFF
