[. . . ] ULTRAMATCH PRO SRC2496 Users Manual ENGLISH ENGLISH Version 1. 2 June 2004 ULTRAMATCH PRO SRC2496 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. [. . . ] Otherwise, the ULTRAMATCH PRO can only be operated as an A/D converter, and the D/A converter function will be muted. APPLICATIONS 9 ULTRAMATCH PRO SRC2496 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 s s s s Conversion of 48 kHz DAT recordings to the CD standard of 44. 1 kHz. Conversion of older digital recordings from 44. 056 kHz to 32, 44. 1, 48, 88. 2 or 96 kHz. Conversion of foreign material with 32 kHz to 44. 1, 48, 88. 2 or 96 kHz. Conversion of audio data with a word length of 24 bits to 20 or 16 bits for recording on a digital medium. Conversion of S/PDIF format to AES/EBU for easy manipulation of various parameters and improved (balanced) signal transmission. Setting or removing copy protect bits for further processing of recordings in a studio environment. The need for synchronization in a digital studio is done justice connecting the equipment to one central sync source. For example, the console could be the master-supplying the remaining equipment with a reference signal (wordclock). However, this will only work if your other equipment has a sync input, i. e. In a studio with a digital tape machine, digital effects and hard-disk recording system it is impossible to connect commercially available CD players or DAT recorders to the mixing section of the console simply because they cannot be synchronized. By inserting the BEHRINGER ULTRAMATCH PRO SRC2496 between the equipment to be synchronized and the mixing console input, the SRC2496 can deliver the audio signal with the studio ). clock rate entered via the external sync input (WORDCLOCK, In this case, the ULTRAMATCH PRO works as intermediate gear of sorts, whose toothed transmission always ensures that there is an appropriate gap in the gearwheel. It synchronizes the signal coming from the devices to be synchronized, while converting to the desired sampling rate in compliance with the wordclock signal. In a studio with a central clock generator, it is therefore possible to use the ULTRAMATCH PRO to connect any unit to any other, regardless of any other options available. s 3. 2. 1 Typical studio application with DAT Only recently has it become possible to use less expensive DAT recorders for direct recording from analog sources with a sampling rate of 44. 1 kHz. Usually, such recordings have to be transferred via an analog connection from DAT to a professional recorder. This process results in an unnecessary deterioration of the original quality of the material due to the additional D/A and A/D converters involved. With the ULTRAMATCH PRO you can eliminate this problem by converting the sampling rate purely in the digital domain, which allows for a considerably higher quality than you could achieve with analog converters. Further problems, such as incorrect formats, significantly deviating or unstable sampling rates (as long as they do not deviate by more than ±12. 5% from the current sampling rate), will also be corrected by the ULTRAMATCH PRO in real time, thus ensuring the successful transfer of your audio data. + Even if the central clock does not correspond exactly to one of the sampling rates, the ULTRAMATCH PRO will assign a corresponding marker to the output signal!This marker depends on the automatically detected and displayed sampling rate, which is important because DAT recorders usually refuse to enter record mode if an incorrect sampling rate has been indicated. 3. 2. 4 Bridging unformatted passages DAT recorders, in particular, produce tiny format gaps between individual recorded passages on the tape when intermittent recordings are made. Also, when you transfer older recordings it can happen that short passages with a different sampling rate than that of the current recording remain stored on tape.
