【Bluetooth Input Expansion Card for HELIX NEXT Series｜EXTENSION CARD 2.0 BT-HD】

This is a Bluetooth input expansion card for HELIX NEXT series DSP/processors, designed for those who want to enjoy music from a smartphone wirelessly even inside the car.

When you install EXTENSION CARD 2.0 BT-HD into the DSP, you can wirelessly input music signals from Bluetooth devices such as a smartphone. In addition to SBC and AAC, it supports Qualcomm aptX and aptX HD as well. With compatible devices, you can enjoy a sound with relatively rich information content even over a Bluetooth connection.

Since the received audio is digitally transmitted into the DSP, the key point is that you can use the Bluetooth input together with the DSP’s tone adjustment functions. You can fine-tune the cohesiveness of the sound while balancing it with the car’s speakers, subwoofers, and your existing system.

The unit also includes optical digital output (Toslink / S/PDIF). This allows you not only to input into the DSP, but also to send the signal to other digital devices.

It’s well-suited for people who want to reduce the hassle of connecting a smartphone to a cable every time they get in the car, or for those who want to set up a Bluetooth playback environment in addition to their factory audio. Since it supports pairing registration for up to 8 devices, it’s convenient for families who share a car or for switching between multiple smartphones.

However, the compatible HELIX NEXT series DSP models vary by model. Also, depending on the codecs supported by the Bluetooth device, the actual connection method and sound quality will differ. We recommend that you confirm not only whether installation is possible, but also which input method is best to choose for your current system before purchasing.

At LOGON, we work with you to determine whether adding EXTENSION CARD 2.0 BT-HD makes sense—while checking your DSP, speaker configuration, the smartphones you usually use, and how you listen to music. What we can propose will change depending on whether your goal is only to make it wireless, or to improve sound quality with the DSP at the center. Please feel free to consult us in a practical way while confirming compatibility with your vehicle and system.
