Looking for who said what in the sound world? Well there is no better place to find every audio related press release than 3DsoundSurge.!

The optical TOS-Link interface (light pipe) can handle either 8 channels in ADAT^TM format, or a stereo S/PDIF signal (up to 24-bit/96 kHz). 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/96 kHz) is available to which the ADAT™ signal can be routed and mixed – the EWS88 D can thus also serve as a converter. Of course, the card can also be synchronized with all further EWS-Systems fitted with an EWS-Connect or in addition with a WordClock signal by using the TerraTec EWS ClockWork module. This makes the AudioSystem EWS88 D an ideal complement to a digital project studio.

EWS88 D Technical Data

• Eight digital input and output channels in ADAT^TM format (optical TOS-Link)
• Optical input and output can also be switched to S/PDIF format
• S/PDIF stereo input and output (coaxial, up to 96 kHz and 24-bit)
• Simultaneous recording and playback of up to 20 channels
• 16-, 20- and 24-bit processing of the ADAT^TM signal with up to 48 kHz playback
• Variable sampling rate of the ADAT^TM input signal up to 52 kHz
• 20 channel mixer with 36-bit internal resolution
• Hardware VU meter visualized via software for each channel
• Busmaster transfer supports '24-bit 4-byte mode' (32-bit) to reduce processor loads
• Analog stereo output at up to 16-bit/48 kHz (3.5 mm jack) for MME and DirectSound playback
• Two stereo inputs with up to 16-bit and 48 kHz operation *
• Two independent MIDI interfaces (splitter cable)
• Drivers for Windows 95/98/NT4 as well as ASIO 2.0, Gigasampler GSIF, MME and DirectSound (SystemSound out) support

*) These inputs can only be heard over the SystemSound output.

TerraTec: Synchronisation via EWS ClockWork

Indispensable in modern digital studios: synchronization via WordClock signals. In addition to phase-locked and sample-precise linking of multiple digital data streams, a central studio clock helps reduce jitter to take full advantage of your high-quality converter systems.

EWS cards with EWS-Connect* can be connected internally to the EWS ClockWork module to ensure perfect synchronization with the digital outside world. The module can either transfer the clock signal of a master EWS card to all external devices with a minimum of jitter, or it can follow an external clock. Up to 4 EWS cards with EWS-Connect* in the computer can be coupled in parallel to the WordClock signal using only a single EWS ClockWork module.

Digital technology is continuously gaining ground in studios: optimized, reliable digital connections can be established between mixing desks, tape machines, samplers or synthesizers and the EWS audio systems in the computer with the aid of the EWS ClockWork module.

Keyfeatures:

• Clock module for EWS cards with EWS-Connect
• Clock receiver for up to 4 EWS PCI cards connected in parallel
• Clock transmitter for the clock signal of the EWS PCI master card
• Switchable between standard WordClock and Super Clock (256 FS)
• 1 BNC input as well as 1 BNC output
• Switchable termination
• Jitter less than 3 ns thanks to the use of highly precise microchips

*) EWS audio systems with "EWS-Connect" can be linked and synchronized with one another. Up to 4 systems are possible in one PC by using the same driver and ControlPanel.

The EWS Concept: Flexibility and Performance

TerraTec's EWS technology has been an integral part of many home and project studios the world all over for more than 3 years now. Freaks and pros alike are thrilled by the flexibility and performance of the product range that shattered customary price-performance ratios with the introduction of the AudioSystem EWS64.

Since then, a large number of products have been added to the range with features that not only combine the old and the new, but also push studio standards substantially higher.

The combination of new cards with the existing EWS series results in a concept which unites

• hardware-based sampling (EWS64 with Ed!son)
• hardware-based sound synthesis (EWS64 and microWAVE PC)
• hard-disk recording with the latest converter technology
  (EWS88 MT, Ews88 D and EWS96 M – EWS -Connect)
• broad software support with high performance.
  (e.g. ASIO 2.0, Gigasampler GSIF, various software synthesizers)

This means: Delivering more performance at an attractive price in each of these areas. All of them can be connected and synchronized (internally, various WordClock formats, EWS64 via S/PDIF) in just about any required combination. Up to 40 input and output channels (digital and/or analog, up to 24-bit/96 kHz) are supported for hard disk recording. All systems with EWS-Connect can be synchronised internally by using just one driver (MME, GSIF or ASIO 2.0!) and just one ControlPanel. The carefully designed, user-friendly software ensures that the system – regardless of the configuration – remains easily controllable and flexible.
