Up to eight devices, each fully equipped with an AC headset and a patient response switch, can be connected to a single PC via an interface box and operated simultaneously by just one tester. Voice-instructions are given automatically in multiple languages and the tester can also address the test subjects through the microphone.

Customize the settings for automatic testing to match the specific needs of your hearing conservation program. The RA660 makes it easy to meet standards and individually set requirements with an integrated Bio-Acoustic Simulator that performs daily calibration and listening tests, as well as an optional room monitor that constantly analyzes the ambient noise conditions.
