FOSTEX VC-8 8CHANNEL ANALOG-ADAT CONVERTER

The 8 channel Fostex VC-8 Analog/ADAT converter offers users of Fostex Digital Multitracks
and PC soundcard users the flexibility of adding more analog inputs and outputs. This is
particularly useful in a ?live? recording application where the number of simultaneous recording
tracks (from analog sources) can be maximized. Inputs and outputs are via RCA pin connectors
and utilize excellent quality 20-bit A/D D/A conversion with 32-48kHz digital performance available
enabling seamless integration with digital equipment. Interfacing to an analog mixer is made
simple using the bus selector which can operate in 2, 4 and 8-bus modes.

Features:
Affordable ADAT Optical / Analogue converter
20-bit AD/DA performance
S/P DIF / Analogue conversion
Selectable clock - Internal (44.1kHz), Optical, Word (32-48kHz)
enables seamless integration with digital equipment
Input Mode select (2/4/8 buss) for easy combination with any analogue mixer
Word In for sync
Utilizes high quality 20bit AD/DA converters

SUGGESTED APPLICATIONS:
Add analogue I/Os to digital recorders such as D824, D1624, D2424 to maximize
the number of simultaneous recording tracks
Add 8 high quality analog inputs and outputs to a PC sound card equipped with
ADAT optical connectionGreat all-round capability

The Apogee X-Digi-Mix expansion card allows for direct connectivity between
Pro Tools Mix systems and the Rosetta 200 or Rosetta 800. The X-Digi-Mix
card provides superior quality conversion to Pro-Tools Mix users without the
need for an additional interface, and effectively extending the life of their Mix
systems for years to come.

Features:
* Standard Digidesign peripheral connector for interfacing directly to Mix Core
  or Farm cards.
* Superclock (FSx256) output for convenient integration into existing Pro Tools
  configurations.
* With necessary Pro Tools hardware expansion, multiple Rosetta-800s may be
  connected into a system.
* Rosetta 800 may be used alongside an Apogee AD-8000 or Trak 2 outfitted with
  an AMBUS-Digi8+ card as well as any other Pro Tools Mix-compatible hardware.
* Multiple slaved Rosetta 800s may lock to Word Clock or directly to the Digi-mix 
  card for low jitter synchronization of the Pro-Tools system.

The new Fostex HP-A3 is the perfect DAC for Computer Audio. This high quality unit features 32bit D/A Conversion with an integrated headphone amplifier exclusively designed to get the most from and PC audio set-up.

Why settle for 'built-in' D/A conversion when you can drastically improve the quality of your audio with a Fostex HP-A3?

• USB Bus power without using unwanted AC adapter
• Works with up to 24bit/96kHz audio source
• Exclusive PLL power supply is built in to reproduce the stable electrical supply
• High quality analog headphone amp to drive any type of headphones
• Equipped with hgih-grade AKM 32bit(*) DAC AK4390
• Condensers and OP amp designed exclusively for audio products
• USB / Digital (Optical) input selector
• Headphones / RCA (Analog) output selector
• Doubles as D/D converter from USB digital audio to Optical
• An USB/AC adapter from the shelf can be used for use as an Optical / Analog converter

Note: When using the USB input, the sampling frequency is fixed at 96kHz.  Audio file with Fs 32k/44.1k/48kHz will be reproduced by upsampling to 96kHz and the S/PDIF Out is also fixed at 96kHz.
