Product Overview

The L4-RIC-M is a 4 channel RIC hearing aid developed for hearing aid distributors, audiology clinics, hearing centers and professional hearing care businesses seeking a straightforward digital RIC configuration.

Powered by the ACOD2101 intelligent multi-core DSP, the device provides 4 independently adjustable compression and amplification channels, 8 adjustable bands and 16 DSP channels.

Its signal-processing platform combines ERAC 1.0 Dual-Knee compression, AFC 2.0 feedback management, SIW technology and ENDR 1.0 environmental noise reduction up to 16 dB.

Four selectable programs, built-in assessment tools, FM Interface Compatibility and Auto Phone Function add practical fitting and device-management capabilities.

For distributors building a tiered RIC portfolio, L4-RIC-M provides a clearly defined starting configuration before customers move to models with greater fitting capacity and additional directional or environmental-processing functions.

Practical Digital Fitting Architecture

L4-RIC-M provides four independently adjustable compression and amplification channels.

These work together with eight independently adjustable bands, giving fitting professionals defined frequency-specific adjustment points within a compact configuration.

The ACOD2101 intelligent multi-core DSP provides 16 DSP channels for the digital processing architecture.

This structure allows the model to support professional configuration without introducing the broader processing functions available in the higher L-RIC-M models.

For distributors, this creates a simple technical proposition that can be clearly explained to clinics, hearing centers and other professional customers.

The 4 / 8 / 16 architecture also establishes a measurable starting point for comparing the remaining products in the series.

ERAC 1.0 Compression and AFC 2.0 Feedback Control

L4-RIC-M uses ERAC 1.0 Context Analysis Based Intelligent Multi-Compression Technology with a Dual-Knee structure.

The compression platform forms part of the device's digital amplification system and supports the management of different input levels across the fitting channels.

Feedback management is provided by AFC 2.0, together with SIW technology.

These functions create a defined feedback-control architecture within the entry configuration.

For professional customers, the combination of ERAC 1.0, AFC 2.0 and SIW provides a clear set of digital-processing specifications for fitting and product comparison.

Essential Environmental Noise Management

The model uses ENDR 1.0 Environment Detection and Noise Reduction, specified at up to 16 dB.

L4-RIC-M does not include Environment Recognition, Noise Source Tracking and Suppression, dedicated Transient Noise Management or Wind Noise Management.

This distinction is important for product positioning.

Instead of presenting the model as a reduced version of the higher configurations, distributors can position it around essential digital fitting, feedback control and core noise-reduction functions.

Professional customers requiring additional environmental-processing capabilities can then move to the higher levels of the L-RIC-M family.

Microphone Configuration

The supplied specification lists:

• Directional Dual-Microphone Technology — All Direction
• Directional Speech Enhancement Technology — No

This configuration differentiates L4-RIC-M from the Fixed Direction platform used in L8-RIC-M and the Standard directional technologies used in L12-RIC-M and L16-RIC-M.

Keeping this technical distinction visible also helps professional buyers compare models based on verified specifications rather than general marketing claims.

Professional Assessment and Device Control

L4-RIC-M supports 4 selectable programs and includes an Internal Sound Field Assessment and Internal Audiometer.

Additional functions include adjustable turn-on delay, occlusion effect management, low-battery notification, adjustable notification volume, volume control and memory after power-off.

FM Interface Compatibility and Auto Phone Function are supported.

The model uses Standard personalized data storage.

Nano Coating Technology is also included.

These functions make the device suitable for professional environments where fitting, assessment and routine device adjustment are part of the customer-service workflow.

Technical Specifications

B2B Portfolio Role

L4-RIC-M is suitable for hearing aid distributors, audiology clinics, hearing centers, medical device importers and professional hearing care networks that need a clear entry configuration.

Its commercial value is based on transparent technical specifications rather than exaggerated performance language.

The combination of 4 fitting channels, 8 adjustable bands, 16 DSP channels, AFC 2.0 feedback control and ENDR 1.0 noise reduction gives sales teams and professional buyers specific parameters for product comparison.

For multi-tier product planning, L4-RIC-M can serve as the starting SKU of the family, while higher models introduce additional fitting resolution, directional functions and environmental-processing capabilities.
