• Can I connect the I2S port on my Holo Audio DAC to a standard HDMI specific TV?

  No. While Holo Audio uses an HDMI physical connector for its I2S input, the electrical signals are not compatible with standard HDMI video/audio devices like TVs or receivers. Connecting them can cause damage to your equipment.

• How do I access the configuration page for the Holo Audio Red streamer?

  Ensure the Red is connected to your local network. Open a web browser on a computer or phone on the same network and enter the device's IP address or try navigating to http://red/config.php.

• Do I need to install drivers for my Holo Audio DAC on Windows?

  Yes, for Windows users, a specific USB driver provided by Holo Audio (typically available via your regional distributor's website) is usually required for full support of high-resolution PCM and DSD formats.

• What is the I2S pinout configuration for Holo Audio devices?

  Holo Audio uses a specific differential transmission mode for I2S. On many models like the Red or May, the pinout can be configured via DIP switches to match other standards (e.g., ALT1, ALT2). Refer to your specific user manual for the correct switch settings.

• How do I update the firmware on the Holo Audio Red?

  Firmware updates are generally handled through the RedOS web interface. If a new update is available, an 'Update [New!]' button typically appears at the bottom of the configuration page.
