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. ©TerraTec® Electronic GmbH, 1994-2002. [. . . ] The analog connections are electrically independent (decoupled) and can be used simultaneously. Their volume controls are not in the EWS ControlPanel, but in the standard Windows mixer. CD audio playback via these internal connections is realized using the System-OUT described above, not the "musical" part of the EWS system. Suitable cables are normally included with your CD drive or can be purchased separately. 2) 3) 4) 5) 6) 7) EWS® Connect Sync-IN connection. For the internal synchronization of up to 4 EWS PCI cards (5 contacts, the plug must remain on the master card). For more information, please read Chapter "Cascading of multiple EWS systems and synchronization. " starting on page 39. 8) EWS® Connect Sync-OUT connection. For the internal synchronization of up to 4 EWS PCI cards (3 contacts). 9) Jumper 1. Sets the digital input: 1-2 -> Coaxial S/PDIF on the PCI card active. 2-3 -> Digital input on the MIC module active (ADAT or S/PDIF). 24 MIC 2/8 (English) The drivers. Note: The driver designations are based on the PCI card of the complete system and are thus called "EWS88 MT". This does not have any effect on the interaction of the modules, however. 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. As a rule, the sample rates are not "interpolated". In other words, the audio system always automatically sets itself to the sample rate with which an application is recording or playing back. This prevents quality losses due to internal sample rate conversions. There are exceptions, however, which we will be covering below. 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. [. . . ] 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. This is due to the fact that error correction algorithms are obviously used more frequently at some times than at others to compensate for quality differences between individual cables. However, these audio losses are usually so minimal that you need to be careful not to mix up the myth with the reality. [. . . ]
