The new Cello maintains its familiar identity (retaining reference code 10558), yet undergoes a visual transformation through the incorporation of fresh plastics and a redesigned rear panel, catering to the introduction of 2 pivotal enhancements:

    The new Cello offers users the ability to employ 2 distinct types of reinforcement techniques.

Firstly, it features three LCD displays capable of rendering images and animations transmitted from the Maestro software. Additionally, it supports the connection of up to three animated toys, which are linked to Cello's rear panel and can be seamlessly controlled via the Maestro interface.

A complete pediatric system at your fingertips!


With the advent of the assistant monitor, a second operator can now work in tandem with the primary operator during testing procedures. This innovative feature empowers the second operator to not only audibly monitor the stimuli being delivered to the patient but also engage in real-time communication with the primary operator conducting the examination. This collaborative approach enhances the overall efficiency and precision of the testing process.


The stimulus channel (ch1) and the masking channel (ch2) become symmetrical.

The operator can now select the stimulus to be sent to the patient even from the masking channel choosing between Pure tone and Warble tone.


The software will allow the upper limit for the AUD - Speech signal (INT/EXT/USB/MIC) with Cello, settable up to 110 dB HL for AC or AC-INS output types. It effectively manages 110 dB HL as the maximum limit for speech audiometry.

Update Your Maestro Software to Version 1.23.1: to ensure seamless compatibility and access to all the latest capabilities, we strongly recommend updating your Maestro software to the most recent version. Download it from
