DS2000


- enlarged -

The DS2000 is an affordable ADAT & T/DIF interfacer unit for use with the DSP24 or DSP24 MK II PCI recording card. It was designed primarily for the studio users who require ADAT or T/DIF format interfacing between compatable devices and their PC.

Much of today's studio equipment can transmit and receive up to 8 channels of digital audio data streams simultaneously. This allows you to interface data between devices with bit accuracy. The data remains in digital domain and so preserves the utmost quality. There are many devices which utilize these formats such as the Alesis ADAT and Tascam T/DIF digital recorders, mixers, keyboards, computer audio interfaces etc.

The DS2000 allows you to connect any compatible ADAT & T/DIF defices to your home/studio PC. It is as simple as connecting the unit to your DSP24 or DSP24 MK II PCI card using a 44-pin H-BUS cable.

Additionally to ADAT and T/DIF connectors, the DS2000 supports AES/EBU and S/PDIF I/O. This allows you to output or mix audio streams from ADAT-T/DIF channels to S/PDIF or AES/EBU (stereo channel). It is also possible to record from S/PDIF or AES/EBU into an ADAT-T/DIF device. This is a feature which is very useful in many studio situations.

In addition to direct connection to the DSP24 series cards for interfacing with your PC, you can also use the DS2000 as a stand alone interface between an ADAT or T/DIF source stream and a high quality multi-output DAC (digital to analog converter) like the DAC III. For example, this is an excellent way to get 8 x fully balanced (up to) 24bit/96kHz outputs from an ADAT or T/DIF stream supplied from a keyboard or mixer.

Reviews

The dutch magazine Interface (august/september 2001) had a look on the DSP24 MK II together with the DS2000. Their comments: "The Audio DSP24 MKII is a advantageous soundcard of excelent quality. You can make any possible connection with the DS2000."

 Interface

Keys & Audio, the dutch magazine, reviewed the DSP24 MK II combined with the DS2000 in their first issue 2001: "At the moment Hoontech has the best price/quality ratio." / "Very good sound quality." / "Especially the DS2000 is a pleasure to work with.."

Remarks

ADAT from Alesis uses an 8 channel audio transfer protocol so you can transfer 8 channels of audio simultaneously. It's used by ADAT-Recorders, many different mixers and it has become probably the most important standard to transfer 8 channels of digital audio data these days. One optical cable is used to transfer the 8 channels.

 TDIF (Tascam Digital Interface) is a similar interface as ADAT that also allows you to transfer 8 channels of digital audio data. It is used by many Tascam Recorders (such as the DA-88 series) and digital mixing consoles. It uses one bi-directional 25pin D-SUB cable to transfer data.

S/PDIF (Sony/Philips Digital Interface) is a 2 channel protocol that is used for transfer of stereo signals via electrical or optical connections. It is used by DAT recorders, MD recorders, etc. and also more and more soundcards.

AES/EBU is a professional digital transfer format (similar to S/PDIF) that allows longer cable runs without signal loss and is used in professional DAT decks and other pro digital gear.
