The QED Performance USB A to USB B Lead is designed to transmit high-definition digital audio between USB audio components.
Performance USB cable transmits high-definition digital audio between USB audio components (such as a computer or storage device and a high performance DAC) with very low jitter. At QED we have identified that reducing jitter or timing errors within the digital signal makes for cleaner audio transmission, and with USB this is no different.
Triple magnetic screening ensures enhanced signal protection and 24k gold plated connectors for enhanced signal transfer.
24k Gold Plated Shielded Connectors
The Performance USB lead uses 24K gold-plated connectors to ensure a seamless connection and secure fit.
Triple Electromagnetic Screen
Reduces RF noise entering the cable for a clearer signal.
Strict Adherence to USB 2.0 Specification
The Performance USB A to B lead follows the USB 2.0 specification for high-speed data transmission. This makes it ideal for HD Audio DAC applications up to 24-bit 192kHz.
Very Low Jitter
Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source. A Performance USB lead displaying very low jitter is typically measured at 21 ps rms.
