[. . . ] ULTRA-CURVE PRO DSP8024 User's Manual Version 1. 2 June 2001 ® www. behringer. com ENGLISH ULTRA-CURVE PRO DSP8024 SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electric shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure--voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] By taking a situation where the intensity of both pink and white noise found between 20 and 40 Hz is arranged to be the same for both types of noise, it follows that, in the case of pink noise, the same intensity will be found between 10, 000 and 20, 000 Hz, both bandwidths being one octave. However, as the number of discrete frequencies between 10, 000 and 20, 000 Hz is five hundred times greater than between 20 and 40 Hz, it follows that the intensity of White Noise present between these two frequencies is correspondingly greater. LEVEL The output level can be adjusted in 1 dB steps from 0 dB to -48 dB (with reference to the digital maximum). The internal digital signal generator is routed into the outputs when you switch into RTA mode. As a rule, pink noise is used for system measurement. + + Use the RTA-lock function to prevent accidental signal interruption when using the ULTRA-CURVE PRO for live purposes. Before the noise signal reaches the output of the ULTRA-CURVE PRO, it passes the EQ. That's why the current EQ settings have an effect on the noise signal. As a result, it may be necessary to reduce the level parameter value to i. -12 dB, to prevent clipping. 2. 3 AUTO-Q function With the AUTO-Q function it is possible to automatically adjust the equalizer of the UTRA-CURVE PRO. The ULTRA-CURVE PRO measures the total system response including the influence of both the speakers and the room and translates it to the right setting to achieve the desired response. You can use one of the 100 stored equalizer settings as a target curve for the AUTO-Q function. The curve setting will then correspond to the fader positions of the program selected. If no program number has been given, "FLAT" will be displayed, meaning that an attempt will be made to achieve a linear response. It is also possible to use one of the stored EQ curves as a corrective curve for the analyzer measurement, to compensate for any frequency response variations caused by the reference microphone. In the field the chosen program position, and the chosen side (L/R) are displayed. First connect the ULTRA-CURVE PRO as a normal equalizer in the system that will be measured. Connect a reference microphone to the microphone input on the rear panel of the ULTRA-CURVE PRO. The basic settings will be: Basic settings in the RTA SETUP SOURCE MICRO GAIN MODE AUTO MIC CORR NONE AUTO-Q CURVE FLAT RTA OUTPUT PINK Tab. 2. 2: AUTO-Q settings Pressing softkey A in the RTA menu will give access to the RTA toolbox. In this menu it is possible to choose the left, right or both channels to be measured and automatically adjusted. The ULTRA-CURVE PRO automatic measurement procedure has several functions which are designed to prevent unusable settings from being made. OPERATION 17 ULTRA-CURVE PRO DSP8024 more than 12 dB to reach the desired frequency response.
