Safety precautions 1.1 Information regarding the use of loudspeakers Potential risk of personal injury Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels (from approx.
Y8/Y12 loudspeaker 2.1 Product description The Y8 line array module is intended for small to medium scale sound reinforcement applications. When the Y Flying frame is used, up to 24 cabinets can be flown in vertical columns producing a constant directivity dispersion pattern of 80° in the horizontal plane.
2.2 Connections The cabinets are fitted with a pair of NLT4 F/M connectors. All four pins of both connectors are wired in parallel. The Y8 and Y12 loudspeakers use the pin assignments 1+/1–. Pins 2+/2– are designated to actively driven subwoofers. Using the male pas s i ve c r os s over connector as the input, the female connector allows for direct...
The transition from Line to Arc configuration within the array is made according to the splay progression but may allow for certain deviations due to the wiring of the cabinets in groups of up to two. 2.3.1 Controller settings For acoustic adjustment the functions CUT, CPL and HFC can be selected.
2.4 Dispersion characteristics The graphs below show the horizontal dispersion angle over frequency plotted using lines of equal sound pressure (isobars) at –6 dB and –12 dB. The nominal dispersion is maintained above 600 Hz, while a useful horizontal dispersion control is achieved down to 500 Hz.
