USB Bridge

USB DAC headphone amplifier in USB stick format

Cable and accessory specialist Oehlbach presents a compact USB-DAC headphone amplifier with high-end audio performance. The USB Bridge is connected to a vacant USB port on a PC or Mac and can then be used immediately without any special software according to the “Plug&Play” principle. The digital audio signal is then forwarded directly to the USB DAC, simply bypassing the internal, acoustically weak hardware of the PC. Thanks to an excellent D/A converter from AKM and the exclusive low-noise headphone amplifier from Texas Instruments, the “USB Bridge” delivers pocket-sized hi-fi sound. The portable module in the form of a USB stick is enclosed in a high-quality aluminium housing, equipped with an LED indicator and provides a 24-carat gold-plated jack plug socket. All types of music files can be played back, with the device natively supporting input signals up to 96 kHz/24 bit.

One of the most important steps in high-quality music reproduction is the digital-analogue conversion of electrical signals. At Oehlbach, we therefore only use strictly selected components with technical properties of above-average quality. The AK4396 D/A converter is suitable for high resolution sampling rates up to 192 kHz/24 bits and produces only minimal non-linear distortions despite the huge frequency range. The extremely high tolerance to digital jitter is another distinctive feature of the D/A converter from Asahi Kasei. In addition to PCM, 1 bit DSD data signals, needed for the perfect reproduction of DVD audio and SAC media, are also processed.
