動作モード

1. 送信（TX）モード

In TX mode, the device wirelessly transmits audio from a non-Bluetooth audio source (such as a TV or PC) to Bluetooth headphones or speakers. Supported codecs include LE Audio, APTX Lossless, APTX Adaptive, APTX HD, APTX, and SBC. For optimal performance, ensure your receiving device supports the same high-quality codec.

2. Auracast Mode (Broadcast Audio)

Image: This diagram illustrates the Auracast Broadcast Mode, where the eppfun transmitter connected to a TV can broadcast audio to multiple Bluetooth headphones simultaneously, indicated by several headphone icons receiving the signal.

The transmitter supports LE Audio with LC3+ codec, enabling Auracast broadcast audio. This allows an unlimited number of Auracast-compatible Bluetooth receivers to connect simultaneously and receive audio. This mode is ideal for sharing audio with multiple users in a public or group setting.

To activate Auracast mode, refer to the specific instructions for your Auracast-compatible receiving devices and the transmitter's mode selection controls.

LEDインジケーター

The device features LED indicators that provide clear visual feedback on its operational state, including connection status and the active audio codec (e.g., LE Audio, APTX Lossless, APTX Adaptive, SBC).

トラブルシューティング

音声が出ない、または音質が悪い:

• すべてのオーディオ ケーブルがオーディオ ソースと送信機の両方にしっかりと接続されていることを確認します。
• Verify that the audio source is playing sound and its volume is set to an adequate level.
• Check that the transmitter is correctly paired with your headphones/speakers and the appropriate audio codec is active (indicated by the LEDs).
• If experiencing static or noise, try moving the transmitter away from other electronic devices, power outlets, or Wi-Fi routers, as electrical interference can affect audio quality.
• Ensure your receiving device supports the same high-quality codec as the transmitter for optimal audio performance.

ペアリングの問題:

• Ensure both the transmitter and your receiving device are in pairing mode.
• Clear previous pairing records on both devices and attempt to pair again.
• Ensure no other Bluetooth devices are actively trying to pair or are too close, which might interfere with the pairing process.

自動電源オフ：

• The device may have an automatic power-off feature if no connection is established or no audio signal is detected for a certain period. To restart, simply press the power button.

Dual Audio (Echo) or Audio Delay:

• If you hear dual audio or an echo, ensure only one audio output method is active on your source device (e.g., turn off TV speakers if using headphones).
• While the device supports low latency, some specific headphone models or codec combinations might introduce slight delays. Try switching to a different codec if your receiving device supports it.
