Probe Setup

The Probe has a black Acoustic Aperture ring which affects ambient noise immunity and has a subtle effect on acoustic tonality.

Using the ds32a with open or closed aperture is a matter of personal preference.

To open the Acoustic Aperture, rotate the ring anti-clockwise. To close, turn clockwise. The Acoustic Aperture affects the Probe acoustics, subject to the environment in which the ds32a is used. In many situations, the audible differences are very subtle, and the Aperture Ring should then be kept closed to protect the Probe from dust and moisture. The effect of the Acoustic Aperture positions are as follows:

Aperture Closed - The Acoustic Aperture closes the internal Probe cavity, protecting it from dust and moisture, and producing a more “closed” tonality.

Aperture Open - When open, the Acoustic Aperture can improve the acoustics of the ds32a in certain environments. If you are using the ds32a in a high ambient noise environment, try opening the aperture ring. You may find that the more “open” sound is preferable. Then rotate the ring to the closed position when you return to a quiet environment.
