About the A/V receiver firmware:

Each audio-video receiver (A/V receiver) is powered by a firmware version that supports all its features and allows the user to get the most out of the device. Updating the firmware can bring various changes that can improve performance, such as improving compatibility with different multimedia file formats.

To do this, you typically have to transfer the firmware to an empty USB storage device, connect the flash drive to the A/V receiver, and start the upgrade process from the device’s settings menu.

However, this task must be performed carefully in a stable power environment by someone who has fully read and understood all installation steps, or by an advanced user (recommended) – a failed update could result in a serious failure of the receiver’s software.

So if you think this version can improve your AV receiver in any way, please get the desired version and apply the new firmware through the available download button; if not, please visit our website as often as possible to avoid missing out on possible Updates to improve your device.
