In some circumstances you may need to identify the MAC address of your A&H product.

What is a MAC address?

A MAC (Media Access Control) address, is a permanent, fixed hardware address for any network adaptor. Your computer usually has one, maybe two (one for the ethernet port, one for the WiFi if you have both) and Allen & Heath products are no different.

This is different to an IP address, which can be set by the user, or automatically set by a DHCP server.

Why would I want to know my MAC address?

In some complex enterprise network configurations, you may wish to filter what devices are allowed to connect to a network by MAC address, or automatically assign them to a vLan. This is absolutely not required for the vast majority of users. But can be useful if you want to integrate your console, into a fixed venue network for instance. 

How do I find my MAC address?

To find the MAC address of the product, connect directly from the ethernet port of your computer, to the ethernet port of your Allen & Heath product. If you have multiple network adapters such as a WiFi connection. It's advisable to turn this off now.

On a Windows machine, open command prompt by pressing WIN+R, type "cmd" without the quotes into the text box and press enter.

On a OSX machine, open terminal by pressing Command + Space then typing "Terminal" once it appears highlighted in the list press enter.

Once you have terminal or Command Prompt open type "arp -a" without the quotes and press enter.

You should now see a list of all devices connected to your network port. If you have your WiFi connected at the same time, you may also see all your WiFi devices. By default the MixRack and Surface will have the IP address "" and "" respectively. Next to them will be listed their "Hardware Address" this, is their MAC address.
