Upgrade Your TV Audio

HDX21 Rear-trim-tp

With the advent of Smart Televisions, connectivity has changed. Analog outputs have been removed, meaning audio must be connected via eARC or Optical.

Optical is fixed output and therefore has no volume control and HDMI needs to be connected to a capable system. This forces users to upgrade the entire audio system when they only need a simple analog out.

HDX21 solves this problem.

HDX21 Routing

HDMI (eARC) is the default input and will pass through to the output. When a source is detected at Analog Input, it will automatically switch the analog Input to the Output.

When the signal is removed, the switch will remain in the Analog input until the delay time has elapsed, at which point the switch returns to eARC.
