<p>The HD-AUDIO USB-INTERFACE extends Helix devices with a High Resolution Audio USB input and converts a PC or smartphone into a HD-Audio player. The direct digital signal transmission (without additional AD-DA conversion) from the USB module to the DSP with up to 192 kHz / 32 Bit allows lossless audio processing and thus assures perfect sound quality. The device-specific side panel is of course included in delivery.</p>

TECHNICAL DATA

Note: The HD-AUDIO USB-INTERFACE has two operating modes.
Full Speed Mode (default): Highest compatibility with all Android, iOS, macOS and Windows devices. Supports sample rates up to 96 kHz / 32 Bit. No driver installation necessary.
High Speed Mode: Compatible with most of all Android ( Version 6), iOS, macOS and Windows devices. Supports sample rates up to 192 kHz / 32 Bit. An additional driver installation for Windows devices is necessary to use sampling rates higher than 96 kHz / 32 Bit.

Note: No connection wires included. A MiniUSB wire is needed for most configurations. For Android devices an additional MicroUSB OTG cable is required. For Apple devices an additional Camera Connection kit or a Lightning to USB cable is required.
