ULTRACURVE PRO DEQ2496 User Manual Important Safety Instructions Terminals marked with this symbol carry electrical current of sufficient magnitude to constitute risk of electric shock. Use only high-quality professional speaker cables with ¼" TS or twist-locking plugs pre-installed. All other installation or modification should be performed only by qualified personnel.
ULTRACURVE PRO DEQ2496 User Manual 1. Introduction 2. Control Elements Thank you very much for expressing your confidence in BEHRINGER products by purchasing the ULTRACURVE PRO DEQ2496, an extremely high-quality DSP-based digital audio processor with built-in 24-bit/96 kHz A/D and D/A converters, making it an ideal tool for both live and studio applications. 2.
ULTRACURVE PRO DEQ2496 User Manual (9) The DEQ2496 has three DATA WHEELS, which can be used to select and edit various parameters—again depending on the currently selected menu. Often, they perform a dual function, i.e. you can edit by turning and pressing a data wheel. Pressing the data wheels also changes the scaling of many parameters (step width) or confirms/resets previously made entries.
ULTRACURVE PRO DEQ2496 User Manual Turn the upper data wheel to select a frequency band for editing with the FREQ parameter. 31 bands are available comprising the entire frequency spectrum from 20 Hz to 20 kHz. With the large data wheel (GAIN) you can boost or cut the level of the selected band. The setting range is from -15 to +15 dB. VPQ (Virtual Paragraphic Equalizer) function The lower data wheel (BW/OCT) additionally assigns the required bandwidth to the filters.
ULTRACURVE PRO DEQ2496 User Manual On pages 1 and 2 of the DEQ menu you can adjust the necessary settings to determine the threshold and the way of sound processing. Additionally, you will find a graphic representation of the control curve with regard to THRESHOLD, GAIN and RATIO. In the center of the display, the LEVEL meter (left) indicates the filtered DEQ input level (control signal), while the GAIN meter (right) shows how much boost/cut is applied to the signal.
ULTRACURVE PRO DEQ2496 User Manual The first page shows a graphic representation of the filters. It is structured and operated in the same way as the first page in the PEQ menu. Since this menu can only be used to cut signals, the 0 dB line is located in the upper part of the display. The differences here are the settings ranges for the GAIN and BW(OCT) parameters. In order to achieve extremely narrow-band filters with high attenuation factors, the bandwidth ranges from 1/10 to 1/60 oct.
ULTRACURVE PRO DEQ2496 User Manual The parameter STEREOWIDTH offers a setting range from 0 to 3.0 (large data wheel), and defines how clearly the two sides of the stereo image are separated from each other. With the upper data wheel you can edit the ASYMMETRY parameter and thus the relative volume of the left and right stereo signal, within a range from -90 to 90°, but without affecting the center mono signal.
ULTRACURVE PRO DEQ2496 User Manual The HOLD function determines how long the signal level is reduced, once the threshold has been exceeded (upper data wheel). Only when this time has expired (0 - 1,000 ms), will the RELEASE parameter take over. The control range of the THRESHOLD parameter (large data wheel) is from 0 to -24 dB, RELEASE can be adjusted between 20 and 4,000 ms (lower data wheel). A long key press on the B key resets the LIMITER parameters to their default values.
ULTRACURVE PRO DEQ2496 User Manual MIDI When this parameter is ON, you can display all subsequent MIDI configuration categories. When set to OFF, the DEQ2496 does not respond to any MIDI data. MIDI CHANNEL Here you can select the MIDI channel (1-16) on which the ULTRACURVE PRO transmits and receives MIDI data. CONTROL CHANGE The exchange of CONTROL CHANGE data refers to the GEQ module only (CONTROL CHANGE 1 - 31: left channel / CONTROL CHANGE 33 - 63: right channel).
ULTRACURVE PRO DEQ2496 User Manual Depending on the channel selected, the large data wheel now controls the left or right stereo side of the output signal (DELAY LEFT and DELAY RIGHT) or even both at the same time. Press the wheel to select a coarse or fine adjustment scale. ◊ The AUX output allows you to send out both the delayed and the undelayed signal. This way, you can set up a delay line without any additional equipment (see also chapter 4.4). 3.
ULTRACURVE PRO DEQ2496 User Manual ◊ When you activate the AEQ menu, the current GEQ settings will be taken over and used as the desired frequency response curve. Press the large data wheel to exclude individual frequency bands from the AEQ mode. These bands will not be processed by the automatic frequency response correction. It makes sense to exclude the low-frequency range (up to approx.
ULTRACURVE PRO DEQ2496 User Manual To load individual modules from an existing preset, please press the PAGE key to go to the second page of the MEMORY menu. Similar to page 1, you can select a preset from which you want to load a module. Turn the lower data wheel to select the module of your choice (GEQ, PEQ, DEQ, WIDTH, DYN and I/O). Then, press the large data wheel or the B key to load the module (RECALL MODULE). Here, too, you will be prompted to confirm your selection.
ULTRACURVE PRO DEQ2496 User Manual Please observe a few points to achieve optimum results: Before you start equalizing the frequency response of your audio system, we recommend that you listen to “uncorrected” music and speech material, which has proven useful in practice: If distortion occurs, it is liable to be caused by the system and should be eliminated there. B1520 PRO B1520 PRO The setup of the speaker stacks is also important.
ULTRACURVE PRO DEQ2496 User Manual 4.2 Equalizer in the monitor path The use of the ULTRACURVE PRO in the monitor path follows the same basic rules as the sum-signal equalizer application described above. Additionally, the DEQ2496 offers a few features that are particularly useful for monitoring purposes. The Feedback Destroyer helps you identify and eliminate feedback frequencies during sound check.
ULTRACURVE PRO DEQ2496 User Manual 5. Connections 5.1 MIDI connections Unbalanced ¼" TS connector strain relief clamp sleeve Your DEQ2496 incorporates a MIDI interface, which allows you to send and receive MIDI data. It is thus possible to integrate the unit into a recording studio and control it from a computer-based sequencer program. tip The MIDI connectors on the rear of the unit are internationally standardized 5-pos. DIN jacks.
ULTRACURVE PRO DEQ2496 User Manual 5.4 WORDCLOCK connection If several devices shall be embedded into a digital recording system comprising, for example, a digital mixing console, all connected digital devices must be synchronized using a common wordclock signal. To this end, your DEQ2496 features a wordclock input, which can be used to control external equipment via wordclock signals. The input supports the sample rates 44.1, 48, 88.
