ULTRAGRAPH DIGITAL DEQ1024 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.
ULTRAGRAPH DIGITAL DEQ1024 1. Introduction 1.1.2 Initial operation In addition to graphic EQing, the ULTRAGRAPH DIGITAL gives you a wide array of additional functions, such as feedback destroyer, pink noise generator, limiter/noise gate etc., leaving no wishes open. With these and many more features the DEQ1024 is an absolutely all-purpose device for your recording or mastering studio and will definitely upgrade your equipment.
ULTRAGRAPH DIGITAL DEQ1024 Deactivating the search function (feedback suppression remains active): If you now press the ON/OFF switch for a second time, the feedback analysis stops. Those frequencies emitting feedback will continue being lowered (RESET (HOLD) LED is still on). This procedure is well suited for stationary microphones, such as drum microphones. To start the “hunt” for feedback again, hit the ON/OFF switch once again. Displaying the feedback frequencies: If you briefly (for approx.
ULTRAGRAPH DIGITAL DEQ1024 (9) The DEQ1024 features a LOW CUT and HIGH CUT filter in its FILTER section, allowing you to limit the entire frequency spectrum upward or downward. The HIGH CUT control is used to determine the cut-off frequency above which the high frequency range is lowered (2.5 - 16 kHz). When turned all the way to the right, the filter is deactivated (OFF). The LOW CUT control is used to determine the cut-off frequency above which the low frequency range is lowered (20 - 160 Hz).
ULTRAGRAPH DIGITAL DEQ1024 (13) The 12-digit LEVEL METER shows the signal level of the input and output signals. Use the METER switch located below it to select the respective signal, whereby the output signal is indicated when the switch LED lights up (green), and the input signal is indicated when the switch LED is not lit. The red CLIP LED lights up as soon as the indicated signal is overdriven.
ULTRAGRAPH DIGITAL DEQ1024 After this editing, you have a basic setup; now, you can do some manual fine-tuning, if necessary. EUROLIVE F1520 Floor monitors The following is true: A linear response curve is not ideal for every application. For example, when dealing with voice transmission, being able to understand the speaker is the most important factor. Therefore, the response curve should drop away in the bass range, since the voice can carry subsonic noise and floor rumble.
ULTRAGRAPH DIGITAL DEQ1024 3.3 Using the ULTRAGRAPH DIGITAL in the studio Additional applications of your DEQ1024 are possible in the studio. Your imagination has no limits. Here are only some of the examples: Center frequency (Hz) 1/3 octave 31 to 63 As equalizer for your studio monitors: You can perform graphic equalization of your monitor sound. Besides, you can supress narrow-band room resonances.
