Tips and Tricks: Optimal Use of the ds32a
Instructions
The ds32a is designed to be very easy to use. However, taking the time to read the User’s Manual
will greatly facilitate the effective and optimal use of the ds32a. These instructions provide valuable
tips that are well worth knowing, to get the most out of the ds32a.
It is also recommended that you read the Sony ICD-UX71/8.1 Operating Instructions to get the most
out of your Sony IC Recorder.
Sound Levels
Adjust the Volume to a comfortable level. The ds32a has powerful amplification. Maximum volume is
not necessary in most situations. Experiment to identify optimal settings and personal preferences.
When recording, higher volumes ensure better recording quality.
ANR2 Ambient Noise Rejection
The ds32a has second generation Ambient Noise Rejection (ANR2), enhancing the noise rejection
capability of EmD technology. The noise rejection function can be activated or deactivated, providing
you with complete control over signal processing functions. Experiment with each setting to select
the best for each situation.
Diaphragm Pressure and Skin Contact
The ds32a Probe uses Electromagnetic Diaphragm (EmD) technology which is pressure-sensitive.
Sound characteristics change as the Probe is applied with greater pressure to the patient. Simply
apply the Probe to the patient as with a conventional stethoscope, and make subtle changes in
pressure, listening for desired sound. Lighter pressure is usually optimal. Increase pressure
gradually to increase sensitivity and volume. With signifi cantly increased pressure, low frequencies
will suddenly be attenuated and lung sounds will be audible over heart sounds. Apply steady
diaphragm pressure for best results. The ds32a’s EmD diaphragm operates best when in direct skin
contact with the patient.
Maintaining Performance
Your ds32a is a robust instrument designed to provide continued peak performance. If your ds32a is
not meeting your highest expectations, please contact us so that we can help you obtain and
maintain the performance level for which it is designed.
