LiNKFOR Digital Optical Audio 3x1 Switch Instruction Manual

1. ການແນະນໍາ ແລະຫຼາຍກວ່າview

The LiNKFOR Digital Optical Audio 3x1 Switch is designed to expand the optical audio input capabilities of your audio system. It allows you to connect up to three optical fiber signal sources (SPDIF/TosLink) to a single SPDIF/TosLink receiving device, such as a soundbar, amplifier, or headphones. This device is ideal for managing multiple digital audio sources without constantly plugging and unplugging cables.

It supports various audio formats including LPCM2.0, DTS, and Dolby-AC3 at 96Khz. Please note that it does not support 7.1CH Dolby Digital Plus or Dolby TrueHD, as these formats cannot be transmitted via fiber optic cable and require an HDMI cable for transmission.

The switch supports long-distance signal transmission up to 40 meters (130 feet) when using optical fiber cables with loss less than 0.2Db/m. Its high-grade aluminum alloy design ensures overall shielding without signal interference, contributing to high-quality audio signal transmission. Additionally, it features over-voltage protection to prevent damage from incompatible power adapters.
