• Amplification Modes: Amplify mode with Adjustable Volume provides low distortion, high power amplification, while standard Acoustic mode provides the familiar sound of a conventional acoustic stethoscope. Both modes utilize signal processing designed to provide very high signal definition.

• 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 Stethoscope 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 when 2-stage noise rejection is redundant. This continues Thinklabs’ goal to give the user full control over every aspect of the listening process to fully optimize auscultation.

• User-programmable Presets: You can preset the ds32a to power-up in mode settings to match your clinical habits and needs. The ds32a Stethoscope 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 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.

• Custom Stethoscope Tuning: If your ds32a Stethoscope does not perform according to your requirements, please contact us. While we cannot guarantee it, we may be able to fine tune the sound of your ds32a to meet your needs.
