TC19LL
L-Shaped Pure Silver Digital Signal Cable
Comet Gold Conductor Structure
Comet Gold adopts a 5‑wire parallel structure. Power lines run along both sides, separated by CC signal conductors in the center. The data lines use pure silver conductors, with two independently insulated pairs twisted together and wrapped in gold‑plated shielding.
The increased number of conductors does not affect cable flexibility, providing excellent bending performance.
Directional Connection
When outputting USB audio signals, the system identifies an OTG device by detecting the resistor inside the USB‑C plug.
・For example: When a player acts as a USB decoding device, the mobile phone serves as the OTG output for music playback, and the end connected to the player is the signal input.
・If the player itself serves as the OTG output, the plug orientation must still be followed before connecting to other USB DAC devices.
CNC Full‑Metal Shielded Plug
The plug housing of TC19LL is machined from aviation‑grade aluminum via CNC. The three‑piece assembly structure fully shields the soldered area. The USB‑C plug PCB is redesigned, resulting in a smaller profile than the TC09L plug.
Stepped Non-Slip Ergonomic Design
The shell adopts a textured stepped structure, which prevents slipping when pinched by fingers, making plugging and unplugging more labor-saving and smooth.
