A Quick Guide to the basic B2 functions:

The guide uses the following way to describe a series of actions when using the front panel controls -

Main menu > Settings > Select > Setup WiFi > Select > 'Scanning'...

Which is a shorter way of saying -

Press the Control to access the Main menu > Rotate the Control until you see Settings > Press the Control to select > Rotate the Control until you see Setup WiFi > Press the Control to select > the display shows 'Scanning'...

When using the Remote Controller -

Up, Down and OK are the equivalent of rotating and pressing the Control on the front panel

Prev to play previous track

Find to start Search

Del to delete characters

Back to go to previous menu or exit menu

Rand. to toggle Random mode on and off

Software version

New features and software updates are frequently being added, so please keep checking the website for the latest version -

Go to Questions > Latest Software  (Link)

You can check your B2 software version using the Remote Controller - 



Software update

To do a Web Upgrade from the front panel -

Main menu > Settings > Select > Web Upgrade > Select

You'll need an internet connection to do this

No internet connection - see 'Latest Software' page (Link) for how to update using a USB memory stick


Connect to the internet using WiFi

Main Menu > Settings > Select > Setup WIFI > Select > 'Scanning' > Select a network > Enter the password > NEXT > 'Connecting 1' > 'Sucess!'

If you see 'Failed' > disconnect the power from the B2 > reconnect power and try again

The B2 will now display an IP address and then try to connect to the internet. Once connected the B2 will display the time.

Play a CD

Insert CD - wait for CDDB lookup > choose a Title (there are often more than one) > Press PLAY (if you press the Control Knob at this point it will rip the CD)

If you select a Title, Track names will be shown as the CD playing

Random play mode can be selected

If you decide to rip the CD > Main menu > CD Functions > Rip CD

Rip a CD

This is best done after connecting to the internet so the B2 can use the online CD database, which is usually more up to date

Insert CD - wait for CDDB look up > choose a Title > Select to start ripping



When you rip a CD the B2 copies the CD in the original WAV format. This is then compressed to either FLAC or MP3 when the B2 sitting idle (not playing music). To set Compression -

Main menu > Settings > Select > Compression > Select > Choose FLAC, MP3 or None > Select > 'Saved'

CD Title not listed on CDDB

Rip the CD with the Album number the B2 has assigned it e.g. 'Album 248' and rename it later

The tracks for 'Album 248' will be numbered as Track 1, Track 2, Track 3, etc. These can be renamed later

Rename an Album

Main Menu > Browse Albums > Select > scroll to 'Album 248' > Select > Rename Album > Select > press BACK to delete characters > Enter new name  > press and hold NEXT > 'Done'

Using the Web UI to Rename is quicker and easier (Link)


Find an Artist, Album or Track

Main Menu > Search > Select > Input search clues (text) > Press NEXT to view the result/s > Select an Artist, Album or Track > Pick Album/Track > Press PLAY to play or press Control Knob to see Menu options
Finding an Artist, Album or Track is much quicker and easier using the Web UI.
