[. . . ] 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. [. . . ] SINE f You use this field to set the frequency of the sine wave. It is adjustable in 1/60 octave steps from 20 Hz to 20 kHz. 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. (The target curves for each channel may differ from each other). 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. Make sure that the RTA setup is correct. 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. Pressing the softkey A will open the AUTO-Q menu. [. . . ] This also applies to defects caused by normal wear and tear, in particular, of faders, potentiometers, keys/buttons and similar parts. Damages/defects caused by the following conditions are not covered by this warranty: s misuse, neglect or failure to operate the unit in compliance with the instructions given in BEHRINGER user or service manuals. s connection or operation of the unit in any way that does not comply with the technical or safety regulations applicable in the country where the product is used. s damages/defects caused by force majeure or any other condition that is beyond the control of BEHRINGER.
