Using the Sonifex AVN - TB10AR is quite straightforward. First, connect it to your existing audio system or network. You can use the 4 - wire analogue inputs/outputs for legacy systems or the AoIP network audio connectivity for new AES67 infrastructure. For audio input, you can plug in your microphone or headset into the corresponding ports. Adjust the volume of the headphone or speaker outputs using the volume control buttons. When using the talk buttons, the illuminated key - caps make it easy to see which one you're pressing. Make sure to keep the device in a well - ventilated area as it can generate some heat during operation. Avoid exposing it to extreme temperatures or humidity. For maintenance, periodically check the connections to ensure they are secure. If there are any issues with audio quality, check the audio settings on the front panel display or through the Ethernet webserver. The dual power supply inputs provide a backup in case one power source fails, but it's still a good idea to have a stable power supply. Clean the device with a soft, dry cloth to keep it in good condition.
