4.2 HiFi Digital Audio Decoding

The LS-TC2 incorporates a high-performance DSP audio decoding chip, enabling direct playback of high-resolution audio without the need for additional equipment. It supports lossless audio decoding up to 384kHz/32bit, providing a superior audio experience compared to standard earphone cables.

The cable utilizes a true balanced audio output design, connecting directly to the DSP chip's L+, L-, R+, R- audio signal pins. This architecture effectively enhances dynamic range, improves channel separation, and minimizes interference, resulting in a high signal-to-noise ratio (SNR >122dB) and ultra-low distortion (THD+N <0.001%).

4.3 Parametric Equalizer (PEQ) Adjustment

The FiiO LS-TC2 supports 8-segment high-precision PEQ adjustment through the FiiO Control APP (Android version only) and web interface. This allows you to customize the frequency response curve of your earphones to match your personal listening preferences.

• Customization: Adjust the frequency points, gain, and Q value of your earphones to create a personalized sound signature.
• Saving Options:
  1. Save to device: Write the PEQ curve directly to the LS-TC2 device.
  2. Save to local data: Save the PEQ curve as a local file on your device.
  3. Save to local EQ override: Replace an existing local PEQ curve file.
• Cloud Sharing: Within the FiiO Control APP, you can upload and share your personalized PEQ adjustment schemes, or download PEQ schemes uploaded by other users to experience different sound tunings.

5. Maintenance

To ensure the longevity and optimal performance of your FiiO LS-TC2 cable, please follow these maintenance guidelines:

• Cleaning: Gently wipe the cable with a soft, dry cloth to remove dust and dirt. Avoid using harsh chemicals or abrasive materials.
• Storage: Store the cable in a clean, dry place away from direct sunlight and extreme temperatures. Avoid tangling the cable to prevent damage to the internal wiring.
• Handling: Always grasp the connectors when plugging or unplugging the cable, rather than pulling on the cable itself.
