Product Overview

The L4-RIC-S is a 4 channel RIC hearing aid developed for hearing aid distributors, audiology clinics, hearing centers and professional hearing care organizations that need a straightforward digital RIC configuration with a clearly defined specification level.

Built on the ACOD2101 intelligent multi-core DSP platform, the model provides 4 independently adjustable compression and amplification channels, 8 independently adjustable bands and 16 DSP channels. Its processing architecture combines ERAC 1.0 Dual-Knee compression, DFBC 2.0 Adaptive Feedback Cancellation with two levels, SIW technology and ENDR 1.0 noise reduction specified at up to 15 dB.

Four selectable programs, an Internal Sound Field Assessment, an Internal Audiometer and a group of device-management functions support professional fitting and routine operation.

For distributors, the model provides a clear base-tier option within the L-RIC-S family and creates a measurable starting point for comparison with the higher-channel configurations.

A Clear Base-Tier Fitting Architecture

The core of L4-RIC-S is a compact 4 / 8 / 16 structure: 4 independently adjustable fitting channels, 8 independently adjustable bands and 16 DSP channels.

This architecture gives fitting professionals defined frequency-specific adjustment points without introducing the larger channel structure used in L8-RIC-S, L12-RIC-S and L16-RIC-S. It is therefore suitable for product programs that require professional digital fitting functions while keeping the specification straightforward.

For B2B buyers, the advantage of this configuration is transparency. Sales teams can explain the model using measurable technical data rather than relying on broad terms such as basic or advanced.

The relationship between fitting channels, adjustable bands and DSP channels also makes the product easier to place inside a structured multi-model portfolio.

ERAC 1.0 Dual-Knee Compression

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

ERAC 1.0 forms part of the digital amplification architecture and works across the independently adjustable fitting channels.

The technology provides a common compression foundation for the L-RIC-S family, allowing distributors and hearing care professionals to compare higher models without changing the underlying compression platform.

This continuity is useful in professional product training because model progression can be explained through channel capacity, environmental processing and data-storage differences rather than through unrelated processing systems.

DFBC 2.0 Feedback Management

Feedback management is provided by DFBC 2.0 Adaptive Feedback Cancellation with two levels. SIW technology is also included.

The combination gives L4-RIC-S a clearly defined feedback-control specification within its product tier.

For professional fitting applications, this function can be considered together with compression and channel adjustment during configuration.

For distributors, DFBC 2.0 also creates consistency across the family. Since the same feedback-management platform is used in the other L-RIC-S models, the main differentiation between SKUs can remain focused on fitting resolution and environmental-processing capability.

Essential ENDR 1.0 Noise Reduction

Environmental noise management is provided by ENDR 1.0 Environment Detection and Noise Reduction, specified at up to 15 dB.

L4-RIC-S does not include Environment Recognition, dedicated Transient Noise Management or Wind Noise Management. This gives the model a deliberately streamlined environmental-processing configuration.

The product can therefore be positioned around professional digital fitting, feedback management and essential noise reduction. Customers that require additional environmental functions can move to higher configurations within the same family.

This product logic is useful for distributors because it keeps the base tier distinct and provides a clear upgrade path.

Professional Fitting and Assessment Workflow

L4-RIC-S provides 4 selectable programs and includes an Internal Sound Field Assessment and Internal Audiometer.

These built-in functions support professional assessment and fitting workflows in hearing centers and audiology clinics.

Additional operating functions include:

• Adjustable Turn-on Delay
• Occlusion Effect Management
• Low Battery Power Notification
• Adjustable Notification Volume
• Volume Control
• Memory After Power-off
• Standard Personalized Data Storage
• Nano Coating Technology

Together, these functions provide a practical operating platform for organizations that need a device that can be integrated into fitting, adjustment and follow-up workflows rather than used as a fixed amplification product.

Portfolio Value for Distributors

L4-RIC-S is well suited to distributors building a tiered RIC range with clearly separated specification levels.

Its commercial proposition is based on 4 fitting channels, 8 adjustable bands, 16 DSP channels, DFBC 2.0 feedback management and ENDR 1.0 noise reduction up to 15 dB.

These points give sales teams a concise technical framework for introducing the model.

The product can serve as the base configuration for customers that prioritize straightforward fitting and essential processing functions.

Higher models can then be introduced according to the need for greater adjustment capacity, Environment Recognition, Wind Noise Management or higher DSP capacity.

This structure helps reduce overlap between SKUs and makes it easier for professional buyers to select an appropriate configuration based on actual product requirements.

Practical B2B Deployment

For importers, distributors and hearing care networks, L4-RIC-S can support product-line planning where a consistent RIC family needs a clearly defined starting tier.

Because the model shares the same ACOD2101 platform, ERAC 1.0 compression and DFBC 2.0 feedback technology used across the family, training materials can maintain a common technical framework.

At the same time, the lower channel count and streamlined environmental package make the model easy to distinguish from the higher configurations.

This combination can simplify catalog organization, distributor education and specification-based product comparison across multiple professional sales channels.
