[. . . ] DEQ2496 Users Manual Version 1. 1 July 2003 ULTRACURVE PRO ENGLISH ULTRACURVE PRO DEQ2496 IMPORTANT SAFETY INSTRUCTIONS DETAILED SAFETY INSTRUCTIONS: 1) Read these instructions. CAUTION: To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside; refer servicing to qualified personnel. 8) Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. [. . . ] A long key press on the B key resets the LIMITER parameters to their default values. 3. 17: Graphic equalizer without frequency response correction (UNCORRECTED) The setting UNCORRECTED retains this mutual influence. With a specially developed algorithm the ULTRACURVE PRO can make up for this phenomenon. To use this characteristic, select TRUE RESPONSE. + The LIMITER function is always active and cannot be switched off. It is also active in bypass mode, however, only works to a limit value of 0 dB, so as to avoid digital distortion occurring on the outputs. 3. 5 UTILITY menu The UTILITY menu provides basic defaults settings (GENERAL SETUP) and MIDI configurations on two pages. The upper and lower data wheels select the parameters, which can then be edited with the large data wheel. + When you keep the UTILITY key pressed for about 1 s, the ULTRACURVE PRO will be locked and cannot be accessed any longer (PANEL LOCKED). Keep the key pressed again to unlock the unit (PANEL UNLOCKED). Fig. 3. 18: Graphic equalizer with frequency response correction (TRUE RESPONSE) The resulting real frequency response now corresponds exactly to the setting made with the graphic equalizer. GAIN OFFSET (EQ) Here, you can correct the overall gain of the EQ modules. RTA NOISE CORRECTION The algorithm used by the RTA (Real-Time Analyzer, warped FFT) leads to inaccuracies with wide-spectrum signals such as noise, due to the asymmetric overlapping of individual frequency ranges. When the built-in noise generator is on or the AVRG setting in the RTA menu has been selected, this correction will be made automatically, and needs not be switched on manually. With all other signals, however, this function should be off; otherwise, the individual frequency bands might be displayed incorrectly. GENERAL SETUP (page 1) Fig. 3. 16: UTILITY menu (page 1) CONTRAST Here you can adjust the display contrast to adapt it optimally to studio/stage environments (large data wheel). 12 3. MENU STRUCTURE AND EDITING ULTRACURVE PRO DEQ2496 SHOW MESSAGE BOX Here, you can determine whether the unit displays dialog windows or not. You can choose between LINE LEVEL, MIC LEVEL and MIC LEVEL +15 V (phantom power). RTA/MIC LINE LEVEL When the RTA/MIC input is set to LINE, this parameter determines the maximum input level (for 0 dBFS (full-scale) from -14 to +22 dBu). RTA/MIC MIC LEVEL When the RTA/MIC input is set to MIC, this parameter determines the sensitivity depending on the microphone connected (input sensitivity: -42 to -6 dBV/Pa). 3. 20: I/O menu (page 1) On the first page you can select the DEQ2496s input source with the large data wheel. You can choose between the analog MAIN INPUT, the digital inputs (DIGITAL XLR or DIGITAL OPT) and the built-in PINK NOISE generator. Use the NOISE GAIN parameter to adjust the volume level of the noise generator (lower data wheel). The upper data wheel controls the sample rate (CLOCK) used by the device. When the digital input has been selected, the sample rate cannot be changed, because the DEQ2496 tracks the sample rate contained in the input signal.
