The B2 is a lot like the JB7. For some - especially
JB7 owners this guide will be all you need.
The menu system, help text and web interface
should be self explanatory.
There is a more detailed document on the
website at www.brennan.co.uk That document
gives more background and will change to
reflect new software.

Music sources
B2 has five music sources
HDD - stands for hard disk drive and is for playing ripped music files -
whether they are uncompressed wav files, lossless flac, or “lossy” mp3
and aac. The HDD music source is selected automatically when you
search or browse through your music collection.
Aux - pressing this button will play music from the Aux-In input. You
can connect this to other audio devices - say an iPod or an amplified
turntable. You can make recordings from this input.
CD - pressing this button plays the CD - or just press play immediately
after inserting a CD.
Radio - this actually means internet radio - so you need an internet
connection. Pressing this button plays the last selected internet radio
station.
Bluetooth - you need to attach the optional Bluetooth dongle for this to
work - do this with the power off. To make life simple - the B2 Bluetooth
is always open - it will pair with any device and just play. So usually you
will control Bluetooth playback from your mobile phone or tablet -
there is nothing to do on the B2. The Bluetooth source button lets you
switch between Bluetooth and other sources.

How to upgrade
I released the initial software in part to satisfy the huge and growing
demand for a JB7 replacement. The software does not begin to exhaust
the possibilities of the hardware - it doesn’t use the TV output for example.
Also the software does not deliver some of the many great ideas you sent
in. And right now B2 has only a simple web interface.
I will continue to develop the software and you can upgrade your B2 over
the internet to take advantage of new features as they come along. Take
a look at www.brennan.co.uk for details of any improvements. You can
find the date of your software with the info button. To upgrade go to Web
Upgrade in the Settings Menu.

Music organisation
B2 organises music hierarchically by artist -> album -> track. Each track
belongs to one album and each album belongs to one artist. Compilation
albums usually use the convention of describing the artist as “various” and
start each track name with the artist.
Compression
B2 can play wav, flac, mp3 and aac (or m4a) files. When B2 rips a CD - it
is ripped to an uncompressed wav file - so that ripping is quick. Later
when the B2 is idle and is about to go into standby it compresses any wav
files into either a large but perfect flac file or a more compact but not
identical mp3 file.
