4 ULTRAMATCH PRO SRC2496 FOREWORD Dear Customer, welcome to the team of BEHRINGER users and thank you very much for expressing your confidence in us by purchasing the SRC2496. Writing this foreword for you gives me great pleasure, because it represents the culmination of many months of hard work delivered by our engineering team to achieve a very a[...]

5 ULTRAMATCH PRO SRC2496 2. CONTROL ELEMENTS 1. INTRODUCTION The BEHRINGER ULTRAMATCH PRO is a fully digital signal processor integrating 24-bit A/D and D/A converters. With its wide range of features, it provides a powerful state-of-the-art interface between the physical reality of music and its recording in digital form. To retain the true authen[...]

6 ULTRAMATCH PRO SRC2496 2. CONTROL ELEMENTS 2.1.1 Monitor and input sections Fig. 2.2: Input section control elements Use the GAIN control to adapt the signal level perfectly to the circuitry of your ULTRAMATCH PRO. The level should be as high as possible, but the 0 dB LED should only light up occasionally or never at all to avoid distortion. The [...]

7 ULTRAMATCH PRO SRC2496 2. CONTROL ELEMENTS The LEDs 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz read the sampling rate selected with the SAMPLE RATE switch. If the sampling rate is preset by an external wordclock or generated via the digital input signal, the LEDs light up constantly, thus reading the external sampling rate (with a deviation of[...]

9 ULTRAMATCH PRO SRC2496 3. APPLICATIONS Digital outputs Fig. 3.1: Example: A/D conversion of a microphone signal Fig. 3.1 shows a typical setup for recording a signal source on a digital recording device (here: hard-disk recording system). If your HD recording system is equipped with a digital interface, you can use the ULTRAMATCH PRO to circum[...]

10 ULTRAMATCH PRO SRC2496 3. APPLICATIONS 3.2 Sample rate conversion No matter what type of digital audio signal you feed into the ULTRAMATCH PRO, it will convert it to a common standard format. Numerous conversion examples can be found in daily studio practice: s Conversion of 48 kHz DAT recordings to the CD standard of 44.1 kHz. s Conversion of o[...]

11 ULTRAMATCH PRO SRC2496 4. TECHNICAL BACKGROUND the signal has been processed with this technique. It is however NOT a modification of the audio signal, but only of the emphasis marker contained in the digital data stream. So much for the theory. In practice, a lit EMPHASIS LED does not necessarily show that the emphasis function has really been [...]

12 ULTRAMATCH PRO SRC2496 There is no doubt that digital signal processing guarantees the lowest distortion and noise values. However, up until now signal conversion, specifically sampling rate conversion, had partially led to considerable distortion and interference: If you tried to use traditional methods, the incoming data quantity would far exc[...]

14 ULTRAMATCH PRO SRC2496 The following figure shows how to correctly connect the unbalanced wordclock input. The wiring scheme is the same as is used for networking in computer technology and you can thus obtain the appropriate accessories (commercially available cable, T-connectors, terminating resistors) in specialist computer shops.
