About A/V Receivers:

Each Audio-Video Receiver (A/V Receiver) is powered by a firmware version that enables all of its features and allows users to make the most of the device. Updating the firmware can bring various changes that should boost performance, such as improved compatibility with different multimedia file formats.

In order to do so, usually, you must transfer the firmware onto an empty USB storage device, connect the flash drive to the A/V Receiver, and initiate the upgrade process from the device’s setup menu.

However, this task must be carefully performed in a steady power environment, by someone who has completely read and understood all the installation steps or by a power user (recommended) – an update failure can cause your receiver's software to encounter serious malfunctions.

Therefore, if you think that this release can improve your audio-video receiver in any way, get the desired version through the available download button and apply the new firmware; if not, check with our website as often as possible so that you don’t miss the update that might improve your device.
