Stealth DC-1 Stereo D/A Converter - Operator’s Manual Note: While the two headphone outputs share the same level setting, each is driven by its own BUF634 high current buffer. This ensures a clean low-impedance signal for each pair of headphones you connect, and prevents interactions between them. Note: By default, the headphone output of the Stealth DC-1 will have a very slight boost applied to the low bass (about 2 dB @ 20 Hz).

Stealth DC-1 Stereo D/A Converter - Operator’s Manual USB Drivers When connected to a computer, the Stealth DC-1 operates as a UAC2 audio device. (The computer recognizes the DC-1 as an “external USB sound card”.) UAC2 (short for “USB audio class 2”) refers to the way in which the operating system recognizes the DC-1. It has nothing to do with USB 1.1 or USB 2.0, which refer to the speeds available using various USB hardware connection options.
Stealth DC-1 Stereo D/A Converter - Operator’s Manual Setup Menu The advanced features on the Stealth DC-1 are accessed via the Setup Menu, which is accessed by pressing the Input / Menu encoder knob.

Stealth DC-1 Stereo D/A Converter - Operator’s Manual SETUP: SRC Enables and disables the ASRC (asynchronous sample rate converter) in the Stealth DC-1. The advanced ASRC implementation in the DC-1 re-clocks the incoming data to a clean clock without changing the sample rate, so you get to hear your original music - bit perfect - but minus the jitter. You might wish to disable the ASRC in order to hear what the original source signal sounds like - including the jitter that is present.
