Setting Up Wifi

You don’t need to connect to Wifi to play music and videos but you need Wifi for some functions like internet radio, the web UI, getting the time and transferring music from a computer.

To set up Wifi you will need to know the name of the network you want to attach to - this is called the SSID. You also need the password. This is a string of letters and/or numbers that is often found on a label on your wireless router.

You only have to do this once.

  1. Push the knob to get into the menu
  2. Select Settings and push knob
  3. Select Setup Wifi and push - the brennan will briefly scan for available networks
  4. Select your SSID and push
  5. Enter the password letter by letter. Capitals are available lower down. Push the knob to add a letter. Press back to delete the last letter. Press next when done. You can abandon the procedure without making any changes by holding back.
  6. the brennan will attempt to connect to the network

After the brennan connects it displays what is known as an IP address on the idle screen.

You can also connect the Brennan to your local network using Ethernet. You will need an inexpensive USB to Ethernet adaptor. You can plug that into USB B instead of the Wifi dongle. No password is needed for Ethernet. The Brennan will display the IP address as before.  

How to Rip a CD

  • Press Eject. Put a CD in the drawer. Press Eject again.
  • The Brennan reads the CD table of contents and tries to find album details online at Musicbrainz.

  • Pick the best match and press Next. Then check that the tracks look OK and press Next to start ripping.
  • The display will show the progress - press and hold the stop button to quit.
  • If you press Play instead of Next the Brennan will play the CD or track

The Web UI

The Brennan can be controlled from a web browser on the same local network. The browser can be on a computer, tablet or mobile phone. This is called the Web UI.

You don’t need the web UI for basic playing - but you will need it for several functions like finding radio stations, setting presets, creating Playlists, ripping CDs - you can think of the web UI as a super remote control.

To start the web UI type the IP Address into the address bar of the browser.

Here I typed the IP address of my Brennan "" into Firefox

Brennan Capacity
