Product Overview

The TW1-IF-C is an 8 channel rechargeable hearing aid developed for distributors, hearing centers, audiology clinics and professional hearing care businesses seeking a practical digital configuration for everyday fitting requirements.

Its ACOD3101 intelligent multi-core DSP platform combines 8 independently adjustable compression and amplification channels, 16 adjustable bands and 32 DSP channels. This creates a structured fitting foundation while keeping the product configuration straightforward for entry-level and value-oriented product portfolios.

TW1-IF-C also integrates AFC 2.0 feedback management, SIW technology, environment recognition, ENDR 1.0 noise reduction, fixed-direction microphone processing and TMT Tinnitus Masking Technology.

Rechargeable operation and a comprehensive range of app-based fitting functions further support professional fitting, adjustment and follow-up workflows.

A Practical 8-Channel Fitting Foundation

The 8 channel rechargeable hearing aid architecture provides eight independently adjustable compression and amplification channels.

These channels work together with 16 independently adjustable bands, giving hearing care professionals frequency-specific control when configuring amplification.

The ACOD3101 processor provides 32 DSP channels, supporting the device's amplification, compression, feedback, noise-management and fitting functions.

For businesses creating a tiered IF-C product range, this configuration provides a clear starting level below the 12-channel and 16-channel models.

Core Sound-Management Technology

TW1-IF-C focuses on essential digital processing technologies rather than the more advanced directional functions available in the higher configurations.

ERAC 2.0 Multi-Compression

ERAC 2.0 Context Analysis Based Intelligent Multi-Compression Technology forms part of the amplification architecture.

It works across the eight independently adjustable fitting channels to manage different input levels within the digital processing system.

AFC 2.0 Feedback Management

The product uses AFC 2.0 together with SIW technology for feedback-management functions.

This designation follows the supplied product specification and distinguishes TW1-IF-C from the DFBC configurations used in the higher models.

Environment Recognition

An Environment Recognition Management System is included as part of the device's digital processing platform.

ENDR 1.0 Noise Management and Fixed Directionality

TW1-IF-C uses the ENDR 1.0 Environment Detection and Noise Reduction System, with noise reduction specified at up to 17 dB.

The model also provides:

• Intelligent Transient Noise Management — 1 Level
• Fixed-Direction Dual-Microphone Technology
• Fixed-Direction Speech Enhancement Technology

Wind Noise Management is not included in this configuration.

This gives the 8 channel rechargeable hearing aid a clearly defined core sound-management package suitable for professional product portfolios that do not require the more advanced adaptive directional technology of TW2-IF-C or TW3-IF-C.

Rechargeable Operation and Tinnitus Masking

Rechargeable operation is confirmed for TW1-IF-C.

This provides distributors and hearing care businesses with a rechargeable digital platform without relying on claims about battery runtime, charging time or battery capacity that are not included in the current specification.

The model also supports TMT Tinnitus Masking Technology.

Tinnitus masking can therefore be presented as a supported fitting function. It should not be described as curing or treating tinnitus unless separate regulatory and clinical evidence supports such a claim.

For product portfolios requiring both rechargeable operation and tinnitus masking, this 8 channel rechargeable hearing aid offers both functions within the same professional fitting platform.

App-Based Fitting and Adjustment

TW1-IF-C supports a broad set of app functions for professional adjustment and follow-up:

• App volume control
• App program switching
• App remote fitting
• App automatic fitting
• App professional fitting
• App smart fitting

The device also includes:

• Internal sound field assessment
• Internal audiometer
• App-based program selection
• Adjustable turn-on delay
• Occlusion effect management
• Low-battery notification
• Adjustable notification volume
• Memory after power-off

These functions give hearing care providers multiple options for fitting and device management while helping distributors offer a product that supports modern professional service workflows.

Personalized Data and Device Protection

TW1-IF-C provides Standard personalized data storage, the base storage level within the three-model IF-C range.

Nano coating technology is also included.

Nano coating should be presented only as a product-protection feature and should not be converted into an IP rating, waterproof claim or specific water-resistance statement without supporting documentation.

Technical Specifications
