USB A to Dual XLR Male Stereo Audio Cable | 32-Bit DAC

Connect Your PC Directly to Professional XLR Audio Equipment

The VODOOL USB A to Dual XLR Male Stereo Audio Cable is the ultimate solution for connecting your desktop or laptop computer to professional speakers, power amplifiers, and stage audio systems. Featuring a built-in 32-bit/384kHz DAC decoding chip — far superior to standard 16-bit alternatives — this cable delivers crystal-clear, high-fidelity stereo sound with an exceptional signal-to-noise ratio.

Made in Mainland China.

Key Features

• Versatile Stereo Conversion: Converts any USB-A port on a desktop or laptop into dual XLR male stereo outputs. The red XLR carries the right channel; the black XLR carries the left channel.
• Wide Compatibility: Connect directly to the XLR input of power amplifiers, active speakers, and stage sound systems for seamless professional-grade integration.
• One-Way Signal Flow: Designed as a one-way adapter — the USB port outputs audio signals to the XLR connectors. Not compatible with microphone input; ideal for amplifiers, active speakers, and stage rigs.
• 32-Bit / 384kHz DAC Chip: Outperforms 16-bit chip alternatives with a higher sampling rate, more refined audio reproduction, greater driving force, and a higher signal-to-noise ratio.
• Y-Type Splitter Design: The splitter point sits approximately 50 cm from the XLR plugs, keeping cables tidy and organized on stage or at your desk.
• Durable Metal Construction: Outer diameter of 6 mm with quality metal connectors for long-lasting, reliable performance.

Important Notes

• This is a one-way signal adapter — USB outputs to XLR only; not for microphone use.
• When connecting to the MIC input of a mixing console, do not activate the 48V phantom power — doing so may damage the cable's internal decoding chip.

Frequently Asked Questions

Q: Can I use this USB to XLR cable to connect a microphone to my computer?

A: No — this cable is designed as a one-way adapter that outputs audio from your USB-A port to XLR-equipped devices such as power amplifiers and active speakers. It cannot be used to connect a microphone to a computer.

Q: Will this USB to dual XLR cable work with my mixing console?

A: It can connect to a mixing console's XLR line input. However, you must not enable the 48V phantom power on the console's MIC input channel when this cable is connected, as this can damage the built-in DAC decoding chip.

Q: What makes the 32-bit/384kHz chip better than standard 16-bit chips?

A: The 32-bit/384kHz DAC chip provides a significantly higher sampling rate, delivering more nuanced and detailed audio reproduction, greater driving force for connected speakers or amplifiers, and an improved signal-to-noise ratio (95–105dB) compared to basic 16-bit alternatives.

Q: Which XLR connector is for the left and which is for the right channel?

A: The black XLR connector outputs the left audio channel, and the red XLR connector outputs the right audio channel, providing clear, colour-coded stereo separation.
