Quick answer
To add Bluetooth streaming to your Helix DSP, install the Audiotec Fischer Extension Card 2.0 – BT HD into the dedicated slot on your DSP or DSP amplifier. This module enables high-quality wireless audio streaming directly to your sound system.
Why choose the Extension Card 2.0 – BT HD?
The Extension Card 2.0 – BT HD is designed specifically for HELIX and MATCH DSP devices that have an Extension Card 2.0 slot. It uses Bluetooth 5.0 and supports aptX HD, AAC, and SBC codecs, ensuring high-resolution wireless audio without degrading sound quality.
Compared to using a separate Bluetooth receiver, this module integrates seamlessly with your DSP, preserving the signal path and avoiding extra cables or power connections. It's a clean, professional solution for adding wireless audio.
Check compatibility before you buy
Before purchasing, verify that your HELIX or MATCH DSP has the Extension Card 2.0 slot. This module is not universal; it only works with devices that support this specific expansion interface. Check your DSP's manual or manufacturer website to confirm compatibility.
If your DSP does not have this slot, you may need to consider an external Bluetooth receiver instead, but that involves additional wiring and may not integrate as cleanly.
Step-by-step installation
- Power down your system: Turn off your car's ignition and disconnect the DSP from power to avoid any electrical damage during installation. Always disconnect power before handling any audio components.
- Locate the Extension Card slot: Find the Extension Card 2.0 slot on your HELIX or MATCH DSP. It is usually a small expansion port on the main circuit board. Refer to your device's manual if needed. If the slot is not present, the module is not compatible with your device.
- Insert the module: Carefully align the Extension Card 2.0 – BT HD with the slot and press it firmly until it clicks into place. Do not force it if it doesn't fit; check the orientation. Ensure the module is fully seated to avoid connection issues.
- Reconnect power and test: Reconnect the DSP to power, turn on your car audio system, and pair your smartphone via Bluetooth. Select the module as the audio source and play music to verify the connection. If pairing fails, check that the module is properly installed and your phone's Bluetooth is enabled.
