After MLx and MLxS, the MicroMLxS radio receiver represents the third generation of the successful universal radio receivers from Phonak.
It is compatible with all Phonak transmitters, WallPilot, virtually all behind-the-ear hearing instruments, Cochlear implant speech processors and
Baha systems.
MicroMLxS is by far the smallest universal FM receiver. It includes features such as multi-frequency, digital frequency synchronization, automatic
power save (sleep mode) and a revolutionary antenna design which makes the orientation of the pins unnecessary. MicroMLxS is the first radio
receiver using ‘Smart Noise Blocker’ technology, a feature which improves sound quality and listening comfort by suppressing environmental noise
when the person using the transmitter is not talking but the transmitter is still on.
MicroMLxS is recommended for babies, children, teenagers and adults.
Special features
Technical Data
• By far the the smallest receiver in the market.
• Compatible with virtually all behind-the-ear hearing instruments,
Cochlear implant speech processors and Baha systems.
• Smart Noise Blocker technology to improve sound quality and
listening comfort.
• Revolutionary antenna concept which makes the pin orientation
• Multi-frequency with digital frequency synthesizer.
• Automatic frequency synchronization (AFS) with WallPilot.
• Direct frequency synchronization (DFS) with Campus SX or any other
Phonak transmitter.
• Intelligent stand-by mode to save power when the transmitter is
switched off.
• Mechanical switch for Off/FM/FM+M.

Switch settings
• For hearing instruments featuring a designated programmable
audio input (DPAI) it is recommended to use the MicroMLxS in
the switch position •.
• For hearing instruments which do not feature DPAI, the switch
position • means ‘FM only’ and the switch position •
• means ‘FM+M’.
