Med-El Opus 2 Cochlear Implant Audio Processor (demo)
The Med-El Opus 2 cochlear implant audio processor was made by Med-El GMBH of
Innsbruck, Austria in 2008.
This cochlear implant audio processor worked with the implanted Sonata.
Note: this is a demo model put out by Med-El so potential cochlear
implant users could see and handle it.
It consisted of three parts—the behind-the-ear microphone/audio
processor, the transmitting coil and the "FineTuner" remote control.

Front view of the MedEl Opus 2 cochlear implant transmitting coil.
This unit consisted of a coil of wire around the periphery of the unit
with a magnet in the center. The magnet in the center of the coil
was oriented such that it attracted the corresponding magnet in the the
center of the Sonata cochlear implant, thus holding the transmitting coil in
place on the outside of the head.

Close-up view of the MedEl Opus 2 cochlear implant "FineTuner" remote
control. Note that
the upper row of light blue buttons are labeled "M" (microphone only),
"MT" (microphone and t-coil together) and "T" (t-coil only).
The four dark blue buttons with 1, 2, 3 and 4 dots respectively
allowed you to switch to any one of the 4 programs (maps) the Opus 2
had.
The remote measured 3⅜" x 2⅛" x ¼" (8.6 x 5.4 x 0.6 cm). |

Close-up view of the MedEl Opus 2 cochlear implant audio processor
showing the triangular battery compartment door latch (left) in the
latched position. This latch
also had another rather-surprising function. It was the on-off switch
for the audio processor shown here in the "on" position. |

Close-up view of the MedEl Opus 2 cochlear implant showing the
battery compartment latch in the unlatched position so you could slide
the battery compartment cover off to replace the battery. You pulled up
the latch from the bottom. This latch
also doubled as the on-off switch
for the audio processor shown here in the "off" position.
