ULTRA-CURVE PRO DSP8024 1. INTRODUCTION The BEHRINGER ULTRA-CURVE PRO is a fully digital sound processing device based on DSPs and 24-bit A/D and D/A converters. The high-speed DSPs are capable of performing any process in fractions of a second, the only element governing their performance being the software. The enormous flexibility available means that the ULTRA-CURVE PRO has a range of features greatly exceeding those found in a conventional analog graphic equalizer—at a price previously unim

ULTRA-CURVE PRO DSP8024 The automatic servo function recognizes the presence of unbalanced connectors and adjusts the nominal level internally to avoid level differences between the input and output signals (6 dB correction). The optional digital input and output (AES/EBU interface) connections are balanced with a negative ground. High-quality connectors ensure isolated, noise-free signal throughput. The MIDI connections (IN/OUT/THRU) have been realized with standardized DIN plug-in connectors.

ULTRA-CURVE PRO DSP8024 When the limiter threshold is exceeded, the indication LIM will appear in the level meter display to indicate that the limiter is attenuating the output. With softkey A you leave the level meter, and return to the main EQ window. With softkey B you erase the maximum levels from the memory. With softkey C / you switch the display from the ULTRA-CURVE PRO input and output. With key D you can choose between three different tables of reference levels. The 0 dB point is indi

ULTRA-CURVE PRO DSP8024 search means that the audio signal is continuously examined for signs of feedback. If feedback is detected, the ULTRA-CURVE PRO will assign an appropriate filter to the relevant frequency and apply narrow band attenuation, also known as a “notch filter”. The parameters which have been used will be continuously displayed. The next feedback will be dealt with by the next available filter. When all the filters have been used, and feedback still occurs, the filter used for th

We recommend that you make use of this feature whenever you have something completely new to do and have to start from scratch. This way, you can carry on without the danger that maybe an old feedback destroyer setting is in the place which could cause problems. In any case it is the quickest and most convenient way to reset all the pa

SHELVING SLOPE This is a tool which you can use to easily add high shelving, low shelving and bell-shaped response curves to the graphic equalizer (see section 2.1.5 on previous page). LIMIT THRESHOLD The ULTRA-CURVE PRO has an integrated digital limiter to protect against overloading and resulting distortion. Its Attack Time is zero, in other words, it reacts “in advance”.

Short decays are necessary to display fast processes, whereas using long decays with static signals will result in a “quieter” display, which is usually desirable for this type of signal. 2.2.5 RTA setup The RTA SETUP menu is opened by pressing the SETUP key.

ULTRA-CURVE PRO DSP8024 = 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 abs

ULTRA-CURVE PRO DSP8024 more than 12 dB to reach the desired frequency response. If this is the case, you may assume that the loudspeaker system being used is not capable of reproducing this frequency (typically if it is a very low or high frequency). The ULTRA-CURVE PRO will therefore completely avoid the boosting of this frequency to any extent. This will avoid any overloading of the loudspeakers. Please bear in mind that the test signal passes through the equalizer during the measurement proc

Apart from the fact that the high sample rate gives the widest frequency response and correspondingly the best possible sound, at this rate the fastest signal processing takes place.
