The USB-SP1 is a powered stereo speaker system utilizing a USB audio and control interface. Ideal for PC speaker OEMs to adapt current models to create USB versions of their products.

Audio outputs are either stereo speaker, or stereo headphone. Audio inputs are USB and microphone. The microphone input is sent via the USB port to the PC.

Volume and mute control can be operated by either the PC or the front panel of the USB-SP1. This allows for central control , avoiding mismatched volume levels in common powered speakers/PC's.

The USB-SP1 uses the standard Windows USB drivers. The identifying code can be easily modified to display any company or brand when the USB driver detects the USB-SP1. Ideal for creating brand recognition for speaker products.
