Wired Mode (3.5mm Audio)
This guide explains how to use your Engage Pro Elite with a wired audio connection.
🔌 What is Wired Mode?
Wired mode outputs audio through the 3.5mm audio jack using an external speaker or amplifier.
In this mode:
- Bluetooth is disabled
- Audio is sent directly via cable
- Connection is immediate (no pairing required)
A video demo for this can be seen here -> Connecting via Aux cable
▶️ How to Enter Wired Mode
- Plug a 3.5mm audio cable into the device
- Connect the other end to:
- a speaker
- an amplifier
- or headphones (for testing)
- Ensure the external device is powered on and volume is set appropriately
- Hold Button 4 on the hand unit
- If Pro Elite is powered on press Button 2 on the main board to reboot it or just power on
- Boot sound will play and Button 4* can be released
✅ Expected Behaviour
- Audio should play immediately when triggered
- No connection delay (unlike Bluetooth)
- Button inputs should trigger sounds as normal
🔁 Switching Back to Bluetooth Mode
To return to Bluetooth mode:
- Simply power the device on without holding Button 4
The device will revert to default Bluetooth behaviour.
❌ Common Issues
No Audio Output
- Check cable is fully inserted
- Check external speaker is powered on
- Increase volume on connected device
Very Low Volume
- Increase volume on external speaker/amplifier
- Check audio source settings
Still No Sound
- Confirm you entered wired mode correctly (Button 4 held at boot)
- Try a different 3.5mm cable
- Test with wired headphones to isolate the issue
🧪 Testing Tip
Wired mode is useful for testing:
- If audio works in wired mode but not Bluetooth → likely a Bluetooth issue
- If audio fails in both modes → check SD card, files, or firmware
