Helix Conductor

       The Helix Conductor masterfully blends aesthetics and practicality. A single knob grants complete command over your sound system’s (DSPs) key features, including volume regulation, signal source choice, configuration alteration, and management of an optional Bluetooth module. Being small in size, yet incredibly powerful and easy to use, it is a no-brainer to add this to your Helix DSP installation.

. Easy installation – 40mm cut-out hole for flush mount installation

. Easily configured and updated via Audiotec Fischer DSP PC-Tool software

Helix HEC Bluetooth HD Card

       The BT HD extension card enhances your Helix DSP device by adding a high-definition Bluetooth® audio streaming capability. It supports up to 576 kbps and a 24 Bit/48 kHz sampling rate, courtesy of the BT5.0+EDR standard. This module is compatible with various audio codecs such as SBC, AAC, aptX, and aptX HD. Moreover, it comes with an optical digital output in SPDIF format. The Qualcomm® aptX™ HD audio codec enables the BT HD module to deliver wireless, uninterrupted HD quality audio transmission. Additionally, the direct transfer of digital signals from the BT HD module to the DSP, without the need for extra AD-DA conversion, facilitates lossless audio processing, resulting in exceptional sound performance. The HEC BT HD enables control functions such as play/pause, track forward/backward, connect, pairing, and disconnect, which can be managed through a connected DSP remote control like the Helix Conductor and Helix Director.

       The enhanced data transfer capabilities of the BT5.0 standard, coupled with the DSP PC-Tool software V5, enable wireless configuration of all DSP devices featuring the ACO platform when used with a PC equipped with Bluetooth® technology. This advancement renders the need for a USB cable connection obsolete (Although we at ResoNix still prefer to use a USB connection for DSP tuning just in case).

. Bluetooth® audio streaming powered with Qualcomm® aptX™ HD audio codec

. High Definition audio transmission with up to 576 kbps and 24 Bit/48 kHz sampling rate thanks to BT5.0+EDR standard

. Supported Audio Codecs: SBC, AAC, aptX & aptX HD
