Congratulations on purchasing your ds32a Recording Package. You now own an instrument
designed for high resolution auscultation - an instrument that produces body sounds with low-
noise and high-amplification, providing a new level of clarity. The ds32a provides unprecedented
control of the listening process, unmatched by any other stethoscope today. Combined with a
digital recorder, the Sony ICD-UX71/81 or other digital audio recorder, it is possible to acquire
auscultation sounds for teaching, electronic medical records, or other purposes and edit/display
sounds using Thinklabs Phonocardiography Software. Features of the ds32a include:
•
Amplification Modes
: Amplify mode with Adjustable Volume provides low distortion, high
power amplification. Standard Acoustic mode provides the sound of a conventional stethoscope.
•
Ease-of-Use
: Three simple controls provide Power on/off, Amplify on/off, and Bell/Diaphragm
selection, with mode changes at the push of a button. Additional features are hidden behind
these keys to un-clutter simple use, while providing new useful functions when needed. For
example, a new Mute function (hold the Amplify key down) provides for muting sound when
patients speak, cry, cough, or produce other unwelcome sounds during auscultation.
•
Patented Transducer
: The Electromagnetic Diaphragm
™
(EmD) senses and converts body
sounds to electronic signals right at the diaphragm, eliminating signal degradation and ambient
noise coupling through air-borne transducers or tubing. The EmD is pressure-modulated. By
subtle variation of Probe pressure, amplitude and frequency response can be tuned to listen to
specific sounds. This provides powerful tactile control over audio characteristics.
•
ANR2 Noise Rejection
: Thinklabs pioneered ambient noise rejection with patented EmD
diaphragm technology and acoustically-vented solid aluminum Probe design. The ds32a builds
on this with 2nd-generation Ambient Noise Rejection (ANR2), a 2nd-stage Noise Rejection (NR)
function for increased noise immunity in high-noise environments. NR can be turned off in
quieter office environments to provide very high-sensitivity, direct-coupled EmD audio.
• User-programmable Presets
: You can preset the ds32a to power-up in mode settings to
match your clinical habits and needs. The ds32a can simply power up in the previous mode
settings, or in specific modes suited to your preferences.
•
Audio Port
: An Input/Output port provides an audio line-level output signal for recording or use
of the ds32a as headphones suited to listening to recorded auscultation sounds.
• Design
: All these features are packaged in a stethoscope that has the form factor and weight
of an instrument
so familiar to the professional community of users.
