B2 Q&A

There is a lot of information in this part of the website. It has been divided into topics using the tabs on the left.
If you are new to the B2 take a look at the video guides first.

There  are a lot of real customer questions here so use the search bar to find if your question has been answered before.


Search the Brennan website using Google 

Can I import my iTunes music collection into B2?

Yes - you need a USB hard disk (or memory stick). Find the iTunes Music folder on your computer and drag it to the USB hard disk. Then plug the hard disk into USB C on the B2 and use.
USB Functions->Import from C

Do I need loudspeakers?

Yes you need loudspeakers. There is no loudspeaker inside B2 - the little holes on the top are for ventilation. You can buy BSP50s from us or use your own.

If I buy two B2s can I transfer music? 

Yes you can export all the music from the first B2 at home to a USB hard disk then import the music into the second at your office.

How do I connect to a Bose Wave Radio?

Use a 3.5mm to 3.5mm jack cable like this. 

You can also use this cable to connect B2 to most Bluetooth speakers

Do I need an App?

Nothing to install - just use a web browser - like Chrome or Safari to control the B2.

Do I need a Bluetooth dongle to control B2 from a mac?

No you only need the Bluetooth dongle if you want to play music from your phone or tablet using Bluetooth. You control the B2 with a Web UI that uses Wifi. Wifi and Bluetooth are two different wireless standards.

Can I link B2 to an Amp?

Yes - see the video guides.

Can I view a list of albums and artists on the b2 like on an ipod?

Yes - on the front panel - push the knob and turn to Browse Artists or Browser Albums and push again. Or better still use the Web UI.

Sonos Clarification

I have seen that the B2 is compatible with Sonos. I connect my B2 through an amp to wired speakers. I would like to be able to also play my B2 music in another room (upstairs).

My understanding is that if I purchase say a Play 1 Sonos speaker for the room upstairs and the updated B2 SD card I would achieve my aim (subject to following the set up procedures and having reasonable wi-fi).

Simple question, is my understanding correct? If so, how would I determine which speakers (wired or Sonos) are used at any given time (I only want to play music in one room at a time)? Can I control it from my laptop/tablet?

Apologies if these are silly questions, but I am new to this and don't want to spend nearly £200 on kit that won't do what I want it to!



Hi Paul
Great question and definitely not silly. Yes your understanding is correct.
What I failed to make clear is that when you combine B2 and Sonos - B2 acts like a disk drive for the Sonos system no more than that. The Sonos does not become a loudspeaker for the B2.
So when you press play on B2 (or the Web UI) it will always come out of the Brennan speakers.
To play music on the Sonos speaker upstairs you need to fire up the Sonos program - I have only tried it with a laptop so I don't know about tablets.
There are really two independent music players - in theory you can play different music upstairs and downstairs - if you ever wanted.

SPDIF Volume

Hi Martin. Thanks for the B2 - brilliant. I'm using the SPDIF output to get best quality, but consequently cannot control volume from the Web UI (which I love!). Is this inevitable? Is there (or will there be) a way to control volume from the web please? At present I have to use energy and walk to another room to use the remote or knob on my amplifier! I don't want to have even more Weetabix in the mornings! Thanks. Paul H.

Hi Paul. There is a technical reason for not having volume - that you might find interesting (or maybe its just me). The SPDIF output comprises of 16 bit samples. If I was to reduce the volume by half (6dB) in the B2 then the output would only really be 15 bits - so it would be effectively be more noisy - poorer quality. This is not a big deal at 6db but if you turned it down say 40dB for background music you would effectively be listening to 8 bit audio.

Having said that I think convenience might trump audio quality on occasions so I could add this as a switchable capability - and have added your request to the wish list. The facility would also benefit owners with Bluetooth speakers for the same reasons.



How to change the Micro SD card

Since Spring 2017 B2s have a micro SD card that is not accesible without opening the box. If you want to change the SD card to increase storage for instance. Uncrew the two screws at the back marked with chevrons.

Then pull the rear panel and attached assembly out slowly about 3cm or 1.5 inches.

You may need to prise the panel out with a screwdriver - thats normal. Take care not to damage the metalwork.

I wrapped tape around the screwdriver to protect the metal.

You can just see the micro SD card and it will pop out when pressed.

Reverse the steps to assemble - again its common for the rear panel to "snap" back into place.

HDD Sleep

Hi Martin.
Very pleased with my new B2, definitely a big advance and some great new features. One concern is that I have noticed that the HDD runs all the time even when the B2 says Standby and nothing has been played for hours. Is this correct as it will surely shorten the actual 'playing' life of the HDD if it is permanently running?
Many thanks, Pete

Hi Pete. Good point - I added an HDD sleep function on 4th April - so upgrade your software. It will power down the HDD in standby - after compression. Or you can force it by holding the stop button. Martin

Is there a printed manual?

We don't have a printed manual beyond the quick start guide. The web is by far best way to document products like the B2. We can add material to reflect new features on a daily basis. We can revise parts that we haven't explained very well or cause difficulty. And of course we can use video to help explain.

Inline switch


There wasn't room to put an on-off switch on B2 - but you may be interested to know about this switch from Amazon for £2.49. It is compatible with the 2.1mm DC jack used by B2 and may be better for you than unplugging or turning off at the mains.

Update 6th March 2017

I'm told that switch on Amazon  has changed and is not compatible - I'm leaving the answer in case you can find something like it elsewhere. I have been using one for more than six months but beware I have had reports they are not so reliable - Martin


Problem Wifi

My B2 connects to my router and can download CD data, play internet radio and support the WEB UI - but only for about 10 minutes. After that communication between the router and the B2 stops altogether, and I have to cycle power to get wireless connectivity again, but only for another ten minutes. Any ideas?

My router is a Technicolor TG588V v2 supplied by my service provider (Fleur telecom) and they don't allow browser access to the router.

Hi Phil

The simplest solution might be to attach a cheap travel router like TP-LINK TL-WR702N £18.99 to your household router with the short Ethernet cable that comes with the TP-LINK - then connect the B2 to the TP-LINK wifi.

But it may be worth phoning Fleur - Virgin were able to sort similar problems for me remotely.
