How Does Audikast 4 Support AUX and Optical Inputs for TV and Audio Systems?

Audikast 4 is designed with both a 3.5mm AUX input and an Optical (SPDIF/TOSLINK) input, making it highly compatible with a wide range of TVs and home audio devices. The AUX input supports analog audio signals with voltage ranges from 0.15 to 1.0Vpk, while the Optical input supports digital PCM audio streams at sample rates between 32kHz and 48kHz and bit depths from 16 to 24 bits. This dual-input design allows users to connect either type of audio output from their TV or audio system effortlessly.

What Are the Benefits of Using Optical Input on Audikast 4?

Optical input provides a clean, interference-free digital audio connection, ideal for transmitting high-fidelity sound from modern TVs and home audio systems. It supports PCM audio, which is essential because Audikast 4 does not decode Dolby or DTS formats natively. Users must set their TV audio output to PCM for compatibility. This input ensures crystal-clear dialogue and music transmission, making it perfect for assistive listening and immersive home entertainment.

How Does the AUX Input Enhance Compatibility?

The 3.5mm AUX input offers broad compatibility with older TVs and audio devices that may not have digital outputs. This analog connection is plug-and-play, allowing quick setup with standard headphone jacks or RCA-to-3.5mm adapters. When the AUX cable is plugged in, Audikast 4 automatically prioritizes this input over the Optical input, simplifying user experience by detecting the active audio source.

Which Audio Codecs and Bluetooth Versions Does Audikast 4 Support?

Audikast 4 features Bluetooth 5.4 with support for multiple audio codecs including aptX Adaptive, aptX-HD, aptX, SBC, and the advanced Auracast LC3 codec. This ensures low-latency, high-quality wireless audio streaming to compatible headphones and hearing aids. The support for Auracast LE Audio broadcast allows simultaneous transmission to multiple devices, ideal for shared listening in home environments.

Why Is Audikast 4 Perfect for Users with Hearing Impairments?

Avantree’s Audikast 4 is optimized for individuals with hearing impairments by supporting Auracast-compatible hearing aids.

This feature enhances accessibility and inclusivity in home entertainment systems.

How Do You Set Up Audikast 4 with AUX and Optical Inputs?

Setting up Audikast 4 is straightforward:

• For AUX input: Connect the 3.5mm cable to the TV’s headphone or audio out jack and the transmitter’s AUX input. Set the TV audio output to “Headset” or external speakers as needed.
