While based on the technology used in the AudioSystem EWS88 MT, the "D" model provides 10 digital audio channels. The optical TOS-Link interface (light pipe) can handle either 8 channels in ADATTM format, or a stereo S/PDIF signal (up to 24-bit and 96kHz). In addition to standard 16- and 20-bit, state of the art 24-bit resolutions can also be transferred. Also, 2 independent MIDI ports and an S/PDIF interface with coaxial connections (up to 24-bit and 96 kHz) is available to which the ADATTM signal can be routed or mixed – the EWS88 D can thus also serve as a converter and/or down-mixer.
Even cascading the EWS systems under one another is possible without a problem. The number of simultaneously available inputs and outputs can thus be increased by the use of up to three additional EWS systems with EWS-Connect*. An internal connection guarantees the sample-exact synchronization of all the cards at any time.
Of course, the card can also be synchronized with a WordClock signal by the TerraTec EWS ClockWork module. This makes the AudioSystem EWS88 D an ideal complement to a digital project studio.
The AudioSystem EWS88 D works straight away with all common audio applications under Windows 95/98 and NT. Drivers for these operating systems are included, as well as support for Steinberg's ASIO 2.0 technology, Microsoft's DirectSound, MME and Nemesys GigaSampler GSIF. And here, too, its uniqueness lies in the details, because the drivers are capable of transmitting 24-bit audio data to the audio software used as a 32-bit data stream. This feature noticeably unburdens the main processor, because unlike with the common packed-byte process, the 24-bit data does not have to first be stacked several times before being transmitted through the 32-bit wide bus.
The software provided leads you directly to the goal of your audio dreams: the expansive control panel permits the routing of the different signal sources and allows synchronization and driver settings. Included in the package: EMAGICs LOGIC 4 for creative music processing with the EWS. In addition, there is SEK'D's popular audio editor Samplitude in a specially adapted version – Mastering features like de-noiser, multiband-EQ and hum compressor included!
*The following applies to all cards with EWS-Connect:
The cards can be cascaded and synchronized with one another to increase the number of audio channels (I/Os).
All cards can not only be synchronized with one another, but with external equipment as well. WordClock synchronization can be realized with the optional EWS ClockWork module.
All cards can be used in the same system with EWS64 series cards and can be connected with them. Synchronization is performed via S/PDIF.
DVD-Player can now send AC3-streams through the EWS88 MT/D digital interface (e.g. to an external Dolby digital receiver). Some AC3 decoders expect a special bit to be set within the AC3 data stream. This can be enabled by setting to "Non Audio" mode in the ControlPanel.
All PCI cards can share an interrupt (IRQ sharing) and support busmastering.
Master / slave settings can easily be defined when cascading.
All PCI cards support ASIO 2.0 (DirectMonitoring is not handled by the ASIO software, however, but is realized in a far more flexible and transparent manner in the EWS ControlPanel).
The control and mixing software (ControlPanel) has a logical design throughout and can be used intuitively by musicians. When using multiple cards, only one application is required which also displays only those controls relevant to the existing configuration.
All cards have a separate SystemSound output (18-bit converter / up to 48 kHz). This can be used for the playback of system sounds or multimedia applications, for example. An separate, very fast DirectSound driver also permits the use of software synthesizers independently of the hard-disk recording system.
All cards offer the option of connecting the audio sides of two CD drives within the computer and mixing them separately. This permits the trouble-free connection of a DVD drive and a CD recorder, for example.
All cards feature a hardware-based process for 24-bit recording and playback in which 24-bit audio data is converted to a data stream with a width of 32
