DUALFEX PRO EX2200 1. INTRODUCTION In purchasing the new DUALFEX PRO Model EX2200, you have acquired an extremely efficient and universal sound enhancement processor. The sound precision and flexibility of the functions are the main outstanding features of this high-end unit. The DUALFEX PRO is one of our state-of-the-art sound enhancement systems offering a special combination of sound improvement designs. The unit can be used wherever professional sound improvement is required.
DUALFEX PRO EX2200 Surround processor A switchable surround processor has also been integrated into the DUALFEX PRO. With this processor the intensity of the stereo effect can be dramatically improved. The program material gains in liveliness, depth and transparency. As in a cinema with its special acoustics, the listener has the impression that the orchestral instruments are placed all around him.
DUALFEX PRO EX2200 1.3 Control Elements Fig. 1.1: DUALFEX PRO front panel The BEHRINGER DUALFEX PRO has two identical channels and provides two illuminated push-button switches and four rotary controls. 1.3.1 The Bass and Multiband Processor Section 1 2 3 4 5 6 Fig. 1.2: Controls of the bass and multiband processor section 1 The IN/OUT switch activates the corresponding channel into operation. With the switch in the OUT position, the unit is bypassed.
DUALFEX PRO EX2200 1.3.2 Surround Processor Section 7 8 Fig. 1.3: Controls of the surround processor section 7 With the SURROUND switch you can activate the surround processor section. Please note that this switch has to be released if you want to process two separate input signals. Otherwise there will be undesired cross-talk between the two channels. 8 The SURROUND control determines the effect of the surround processor.
DUALFEX PRO EX2200 2. APPLICATIONS 2.1 Basic Settings We recommend setting the controls as indicated in the following three sections. This will give you a better idea of switch and control functionality: 1. Set the BEHRINGER DUALFEX PRO to bypass mode (IN/OUT switch not depressed), the TUNE controls to center position and all switches to their OUT position. 2. Turn all other controls fully CCW and depress both IN/OUT switches.
DUALFEX PRO EX2200 2.2.4 Enhancing the Sound of Tape Duplication Even under the most favourable of conditions, presence, liveliness and transparency of the program material will suffer during each copying process. These losses are particularly obvious when copying cassettes while simultaneously using a noise reduction system. With the BEHRINGER DUALFEX PRO, losses during tape duplication can be avoided or compensated for. Provided that the original is of good enough quality with only low noise levels.
DUALFEX PRO EX2200 2.2.7 Sound Enhancement in Hi-fi and Video Of course, the BEHRINGER DUALFEX PRO can also find applications in the fields of hifi and video. The unit is simply placed between the signal source (cassette recorder, tuner, VCR etc.) and the power amplifier. We recommend using the tape monitor inputs most preamplifiers provide, thus the BEHRINGER DUALFEX PRO can be switched into any signal source. 3. TECHNICAL BACKGROUND 3.1 The DUALFEX PROs Main Features The BEHRINGER DUALFEX PRO...
DUALFEX PRO EX2200 reach the ear and are identified by the brain as a tone. Since the string vibrates within itself, the tone not only consists of the fundamental oscillation, but also innumerable upper harmonics which are based on the fundamental wave. The complex vibrations of the string are transferred to the body which, in turn, is also set in motion. The combination of string and body produces the sound of the instrument.
DUALFEX PRO EX2200 3.3.2 Phase Shifting The term phase shift describes the displacement of a signals phase in relation to its point of origin. As a matter of principle, the phase shift produces a delay within the signal. If the delayed signal is added to the original signal, the resultant signal becomes wider. Below time delay values of 20 msec.
DUALFEX PRO EX2200 4. AUDIO CONNECTIONS AND INSTALLATION As standard, the BEHRINGER DUALFEX PRO is installed with electronically servo-balanced inputs. The circuit design features automatic hum and noise reduction for balanced signals and thus allows for trouble-free operation, even at high operating levels. Externally induced mains hum etc. will be effectively suppressed. The audio inputs on the BEHRINGER DUALFEX PRO are balanced.
