Transmission to wireless headphones
Sound through a stereo system
5.1 sound via a soundbar
This adapter enables wireless audio output or via RCA and optical connection - from a TV with HDMI-ARC or an HDMI source
The VAX01301 is used to output the sound from an HDMI signal wirelessly or via RCA (analog) and SPDIF Toslink (digital). This means that wireless headphones or speakers can be used to output the sound. Or active speakers and a stereo system that are connected to the audio outputs via cable.
If the TV has HDMI-ARC (or HDMI-eARC), the VAX01301 can be connected there and thus deliver the internal TV sound from apps and receivers. To do this, HDMI-ARC is activated at the touch of a button. In order to enable stereo and wireless output (5.1 sound cannot be processed wirelessly!), the audio format on the TV must be set to PCM stereo, not bitstream or Dolby.
The HDMI audio extractor can also deliver the sound from a player such as Fire TV, Apple TV, etc. that is connected to its HDMI input. A television, monitor or video projector can be connected to the HDMI output. Ultra HD video resolutions up to 4k 60Hz HDR or Dolby Vision are supported. Stereo sound is also output wirelessly or via RCA / SPDIF from this input. 5.1 sound with Dolby Digital or DTS can only be extracted via SPDIF Toslink. The simultaneous use of wireless audio and audio on the RCA / SPDIF outputs is not possible. The maximum audio format of the player can be limited using the 2.0 / 5.1 or Advanced (Audio EDID mode) selection button. For example, to stereo to enable wireless transmission. In Advanced mode, all audio formats are supported. But higher audio formats can only be transmitted via HDMI, not via RCA or Toslink.
The VAX01301 delivers constant audio output levels. The volume of the digital audio signals can only be controlled after analogue conversion, i.e. in the headphones or on the sound system. Many televisions or media players offer the option of controlling the sound system using a learning remote control. HDMI-CEC is passed through between the HDMI input and output. The VAX01301 is powered via USB (power supply not included), e.g. from the television.
A notice:
- Wireless output via the built-in audio transmitter or via cinch is only possible with stereo sound. When using ARC, please set the TV to PCM to get stereo sound.
- Dolby Digital & DTS 5.1 sound is only output via SPDIF Toslink
- Higher audio formats can only be passed through via HDMI and cannot be extracted
- No ARC sound device can be operated on the HDMI input of the VAX01301. ARC from the TV cannot be passed through.
- The volume control is only possible on the sound device, not on the player or TV.
- Power is supplied via USB (max. 700 mA, power supply is not included)
