RTA OUTPUT

You can choose the type of output signal you need in this field:
PINK = Pink Noise, WHITE = White Noise, SINE = Sine Wave, OFF = Signal Generator Off or INPUT = Input

Signal.
WHITE NOISE is composed of multitudes of sine waves packed close together, of equal amplitude, whose

phases are random compared to each other (statistically different from each other). Their density or, spectral

intensity is constant at any given frequency. With PINK NOISE, the spectral intensity is inversely proportional

to the frequency. In other words, the intensity of White Noise is constant for an absolute bandwidth e.g. 50-

100 Hz, or 5000-5050 Hz whereas for Pink Noise, the intensity is constant over a relative bandwidth e.g. an

octave (50-100Hz, 5000-10000 Hz). The difference between White and Pink Noise can be highlighted by the

following example. 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 correspond-

ingly greater.

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-

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.

If you wish the input signal to be present at the outputs in RTA mode, you must either switch the

ULTRA-CURVE PRO to bypass, using the IN/OUT switch, or select INPUT in the RTA setup menu in the field

RTA OUTPUT.

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. NONE = no corrective curve.
First connect the ULTRA-CURVE PRO as a normal equalizer in the system that will be measured. Connect a

reference microphone to the

MIC INPUT

of the ULTRA-CURVE PRO. Make sure that the RTA setup is correct.
