The 56K Digital Recording System was the first of the Turtle Beach audio 
systems for the IBM PC platform. It made use of the Motorola 56000 Digital 
Signal Processor for accelerating digital audio data transfers through the 
IBM PC's Industry Standard Architecture ("ISA") bus.  

The 56K was designed to be connected to the AES-EBU or S/PDIF jacks on a
professional DAT recorder.  With the included SoundStage graphical audio 
editing software, a 56K system installed in a 286, 386 or 486 Intel PC 
running Windows 3.0 or 3.1 can be used as a complete post-production 
digital audio editing solution. 

The 56K system consisted of three major components: 

1. The 56K-PC Digital Signal Processor Card (a 16-bit digital audio processor 
   on a full-length ISA board)

 


2. The 56K-D Digital Interface Box, which allows your DAT machine to talk to 
   the computer via AES/EBU or SP/DIF-compatible digital formats:

   Front View
   
   
   Rear View


3. The SoundStage digital audio editing software. 

   The Turtle Beach 56K was released in 1991 and went out of production 
   in 1993.
 

NOTE:
  While it is still possible to use a 56K in Windows 95/98, it is strongly 
  recommended that more modern hardware be used in today's Plug 'n Play 
  Windows PC environment.  Voyetra Turtle Beach offers the Montego series 
  of sound cards for use in today's PCI-based PC systems.
