User manual TERRATEC MIC2 8 FIREWIRE

[. . . ] English Manual Version: 1/30/05 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 60065 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 The information in this document is subject to change without notice and shall not be deemed as a warranty by the seller. No warranties, express or implied, are made with regard to the quality, suitability or accuracy of this document. [. . . ] This disables the signal path of the rear sockets. Tip: it is not necessary to remove cables plugged into connectors 7 and 8 on the rear panel when using the sockets on the front panel. The eight balanced outputs are suitable for jack connectors. Activating the direct routing on the front panel will send any input signals directly to the appropriate output (see below). Connect the included adapter cable with two MIDI inputs (IN) and outputs (OUT) here. Two BNC sockets are also available here for WordClock input and output. 16 EWS MIC 2/8 FW (English) 4) WordClock LED. If an input signal is present at the WordClock input, the LED will light up. It does not matter in this case whether the clock signal is valid. The LED therefore is not a status indicator (in the sense of "synchronization OK"). Both interfaces (IN and OUT) can be equipped with optical waveguides (not included) as needed. Devices can also be combined--for example ADAT and DAT recorders. A signal conversion, if needed, can be selected in the EWS Control Panel software (if the module is connected to a computer). All of the settings made in the Control Panel will also apply to stand-alone mode. When cabling digital equipment, always verify the synchronization (master/slave). In stand-alone operation, incoming ADAT signals (IN) are converted digital-analog (D/A) and can be picked up at the analog outputs of the module--depending on their channel assignment (1 to 8). An exception to this is when routing the EWS MIC 2/8 FW digital mixer to a stereo output. This routing has priority and suppresses the ADAT channels assigned to this stereo output. Conversely, all analog input signals are present at the ADAT-OUT when the unit is in stand-alone mode. Gain controllers, phase setting and filters are upstream to ensure an optimal signal prior to the analog-digital conversion. If you are using your EWS MIC module with a computer, please note the wide range of routing options which are described in detail in the chapter covering the EWS Control Panel starting on page 28. 6) IEEE 1394a FireWireTM ports (6-pin) and status LEDs. The included FireWireTM cable (6-pin / 6-pin) connects the unit to the computer. [. . . ] As the AES/EBU protocol is nearly identical to S/PDIF and the transmission essentially only differs in the signal strength, you can make your own converter with a bit of soldering. EWS MIC 2/8 FW (English) 35 Always right on time--digital synchronization. When recording via the S/PDIF interface, ensure that the so-called sample frequency (clock) of the card is synchronized with the source device. To ensure the correct synchronization of the devices, switch the master clock to "External" in the Control Panel (exception: the S/PDIF can be synchronized via the Word Clock interface, but this is rather rare in practice). If you forget this step, audible errors such as dropouts and clicks may occur during recording--and already when monitoring the signal. Naturally, you should also pay attention to the settings of your periphery in the reverse situation (synchronizing an external device with the audio system). [. . . ]
