What is Constraint Layer Dampening Isolation Foot System (CLDIFS)?

The Constrained-Layer Damping Isolation Foot System (CLDIFS) is available on the Opus D/A and Opus CDT. It is similar to Constrained-Layer Damping (CLD) systems, where the primary design technique used to control and attenuate vibrating noise and resonant energy is based on a multi or three-layer ?sandwich? system that is formed by laminating the base layer to a damping layer and the to a third constraining layer. The damping layer utilized in the CLDIFS is a specialized and custom designed viscoelastic polymer material having the highest loss factor to shear modulus ratio. This allows for the effective conversion of the vibrating energy of the shearing forces or deformation of the damping material into heat. In addition to the properties within the custom viscoelastic polymer, the application of the polymer to the base layer and constraining layer has been specifically designed to widen the effective operating temperature range of the damping material thus maximizing the energy dissipation within damping material. The effectiveness of the damping material is further enhanced by the specific design of the constraining layer, which incorporates the semi-rigid sub-plate and isolation feet.

Windows XP (all versions) & Windows 7 (all versions):

  1. Download the StahlTek.exe file.
  2. Run the StahlTek.exe file.
  3. Tell where you like like the files to be placed. For example, C:\StahlTek\.
  4. Navigate to the Stahltek directory on C drive.
  5. Run the file Setup.exe.
  6. Follow the installation directions.

Windows 8 (all versions):

  1. Download the instruction sheet here.
  2. Read through the instruction sheet carefully.
  3. Download the StahlTek.exe file.
  4. Follow the instructions on the instruction sheet.

When using the A.B.C., my DAC shows the same output no matter the sample rate (for example, 44.1kHz is displayed as 192kHz).

Your software may be upgrading (or downgrading) your source. For example, Windows Media Player will downgrade any source over 96 kHz. Another program, such as JRiver, may be set to upgrade a source that is below a certain sample rate. Software does through use of DSP, or Digital Signal Processing. You will need to refer to your software’s documentation.

When using the Ariaa DAC or A.B.C., how can I tell what my output frequency is in Windows?

The Stahl~Tek custom A.B.C. driver comes with tools to measure your output frequency. To use these tools, do the following:

1. Click on the small button to the left of the clock.

3. Select Device. Under Device is “Clock Source.” Your current output frequency is listed here.

2. Click on the red “T.”

When connecting the A.B.C to my Mac via USB, once I connect my DAC or another audio device, the Stahl~Tek A.B.C. dissapears or fails to appear.

This is an issue resulting from Mac’s USB specifications. To resovle the issue, plug the A.B.C. into a different port on your Mac.
