User manual TERRATEC MIC 2 8

[. . . ] English Manual Version: 11. 11. 02 CE Declaration We: TerraTec Electronic GmbH, Herrenpfad 38, D-41334 Nettetal, Germany hereby declare that the products: AudioSystem EWS MIC 2 and AudioSystem EWS MIC 8 to which this declaration refers are in compliance with the following standards or standardizing documents: 1. EN 55024 The following are the stipulated operating and environmental conditions for said compliance: residential, business and commercial environments and small-company environments. This declaration is based on: Test report(s) of the EMC testing laboratory In most cases, the designations used in this manual for software and hardware are also registered trademarks and are thus subject to the relevant regulations. Meticulous care has been exercised in the preparation of all text passages and illustrations in this manual. [. . . ] The AudioSystem EWS MIC2+/MIC8+ features a range of drivers for a variety of applications. The drivers support all bit rates between 8 and 32 bits with all common sample rates between 8 and 96 kHzQ. In other words, the audio system always automatically sets itself to the sample rate with which an application is recording or playing back. In most Windows programs, you will encounter drivers with the designation "EWS88 MT Wave" for recording and playback. In order to address the inputs and outputs of the EWS MIC system, you will also find a numbering that corresponds to five input/output pairs: 1/2, 3/4, 5/6 and 7/8, as well as S/PDIF Left/Right. Please note that they define the physical input or output in the EWS ControlPanel. The "EWS88 MT Wave ½" playback driver is thus not automatically considered to be identical to the analog outputs 1 and 2 of the MIC module. If you are using multiple cascaded EWS MIC systems, the operating system generally numbers the driver names from 1 to 4. "Generally" in this case means that there may be exceptions which are unfortunately beyond our control. Depending on the software, the driver names are displayed with supplements that refer to the audio architecture of the operating system: MME, WDM or DirectSound (see below for more information). Last but not least, there's the "EWS88 MT Digital Mixer" driver (for recording only). If required, it records the sum of all of the audio signals coming together in the system. It can thus also be used for a digital resampling of all driver sources. We have a special treat for you in the form of the lowly "EWS88 MT System Wave" driver for the System-OUT output on the slot plate of the EWS88 PCI card (see page 23). An 18-bit converter delivers punchy sound - we suggest using it for the playback of Windows system sounds (pearls before swine, one could say. . . ) or as an independent output for audio editors or software synthesizers. The latter benefit from the extremely fast DirectSound part of the driver - you should easily reach latency values of less than 10 ms with a software synthesizer. Q With the exception of the "EWS88 MT System Wave" system sound driver; this part of the card works with an 18-bit / 48 kHz AD/DA converter. 25 MIC 2/8 (English) Its counterpart, "EWS88 MT System WaveRec" lets you record signals from your connected CD drives. However, we recommend reading the CD audio data out digitally for quality reasons. Programs that support Steinberg's ASIO (or ASIO 2. 0) interface will display the ASIO driver of the AudioSystem EWS MIC2+/8+ in the relevant dialogs. With ASIO, programs achieve extremely short delays (latency) during audio recording and playback. On fast, cleanly set up systems, latency can be reduced to 1. 5 ms at a sample rate of 96 kHz! The ASIO driver is listed in compatible programs under "ASIO for EWS88 MT/D". The inputs and outputs (generally "busses") available in the programs are called "EWS88 MT (n) Out", wherein "n" is used to distinguish multiple EWS MIC systems (1 to 4). [. . . ] Various manufacturers of software DVD players support the playback of DVD audio material via the audio systems by TerraTec. Signals in Dolby AC3 or DTS format can therefore also be transferred using the digital interfaces. Useful information about digital cables (optical waveguides and AES/EBU). Even when transmitting audio data via optical fibers, a few, usually inaudible, errors may occur. You should therefore be sure to use high-quality cables that are not too long: flexible plastic cables should have a maximum length of 1. 5 m, the less-flexible glass fiber cables may be up to 5 m long and more. Audio differences with digital cables seem improbable at first glance, but they can happen nevertheless. [. . . ]
