ABR and DPOAE System

Simultaneous Auditory Stimulation and Recording


Specs & Resources


This robust auditory research system gets things done. The versatile RZ6 Auditory Processor can provide complex auditory stimulation or reliable animal screening, day after day. High bandwidth provides a dynamic range of up to 115 dB and sampling rates up to ~200 kHz. Built-in attenuators, speaker and microphone amplifiers and even a monitor speaker greatly simplify setup and reduces both the overall footprint of the system and the number of cords needed. The RZ6 quickly connects to the MedusaZ amplifier for low-noise recordings. The power of the RZ6, combined with flexible input/output capabilities, make it ideal for pre-clinical auditory research experiments, from psychoacoustics to rapid phenotyping of deafness models.

Coupled with our proven BioSigRZ software, the Auditory Workstation is well-suited for Auditory Brainstem Response (ABR) screening, evoked potential research, and Distortion Product Otoacoustic Emissions (DPOAE) testing. The BioSigRZ protocol can be set once then effortlessly handed-off to technicians for routine testing. Our proven BioSigRZ signal averaging software includes standard experiments to get you started and provides enough flexibility to grow with your lab.
