这是Wadia网站上对于Direct Connect 技术的介绍,初中英语水平就可以看懂:
Digital Volume Control (with adjustable maximum output level)
Digital Volume Control (with adjustable maximum output level) Since 1992, Wadia has continued to refine the first audiophile-quality digital volume control. It remains the only volume control that delivers the theoretical advantages of volume control in the digital domain. Although less sophisticated digital volume controls can sacrifice resolution, Wadia's volume control with adjustable maximum output level can be optimized to match a wide range of systems, ensuring greater than 16-bit resolution over the majority of the volume range.
High-Current Output Stage
Wadia's directconnect output stage can provide up to one-quarter amp (250 mA) of current, to drive very long cables, and low input impedance amplifiers.
High-Voltage Output Stage
The directconnect output stage can produce up to 4.25 Volts RMS, producing sufficiently loud volume levels even in low-sensitivity systems.
Low Output Impedance
With less than 15 ohms output impedance, the directconnect output stage can drive highly capacitive and low-impedance loads with ease.
Quiet Digital Circuitry
Since the CD player output is connected directly to the amplifier, any high-frequency noise coming from the audio outputs can cause audible distortion. directconnect circuitry uses the most recent techniques to minimize this noise. (See NoiseBlock)
True-Balanced Output
Fully-balanced circuit design - with the inverted signal produced in the digital domain, balanced DACs, and analog output - realizes the benefits of amplifiers with balanced input
