28.Phase Inversion for High Output This button will reverse the phase of the high frequencies output by 180 , so that, the high frequencies cancellation in some fields can be compensated for. 29.Mute for High Output This button mutes the high frequencies output. 30.Threshold Setting To prevent any damage to your speakers effectively, set the threshold of the multi-band limiter at the proper position. 31.Limiter Control Engage this button to activate each band's limiter. 32.
2.Low Cut Engage this button to add a 25Hz low cut filter into the input signal path. 3.Low/Mid XOVER FREQ. Control This knob adjusts the Low/Mid crossover frequency from 44Hz to 930Hz, based on which, the Low/Mid frequencies can be output separately. 4.Mid/High XOVER FREQ. This knob adjusts the Mid/High crossover frequency from 440Hz to 9.3kHz, based on which, the Mid/ High frequencies can be output separately. 5.
3.High Output Connectors (3 and 10) These two XLR balanced connectors are used to output the high frequencies signal. 4.Mid Output Connectors (4 and 11) These two XLR balanced connectors are used to output the middle frequencies signal. 5.Low/LF SUM output connectors (5 and 12) These two XLR balanced connectors are used to output the low frequencies signal. 6.Low/Mid XOVER FREQ. Multiplier (6 and 13) Combined with the usage of the Low/Mid XOVER FREQ.
14.Mute for High Output This button mutes the high frequencies output. 15.CD Horn Abbreviation for 'Constant Directivity Horn', this button can be used to boost the high frequencies, so that the power loss of it during the long distance transmission can be compensated for. 30.Threshold Setting To prevent any damage to your speakers effectively, set the threshold of the multi-band limiter at the proper position. 31.Limiter Control Engage this button to activate the limiter. 34.
6.Low/High XOVER FREQ. Multiplier Combined with the usage of the Low/High XOVER FREQ. (3) knob on the front panel, this button can switch the crossover frequency range to 440Hz to 9.3kHz. Please ensure that, your speaker management system must be powered off before you proceed this switching, otherwise, the offensive switching noise can be heard through your speakers. 8.Operation Mode Option Press the left button, and release the right button to enter into the stereo 2-way operation mode. 9.
b. In Line Connection For these applications, the X-P234 Active Crossover provides XLR connectors to easily interface with most professional audio devices. Follow the configuration examples below for your particular connection.
