Revolabs FLX Review

Revolabs may be one of those companies you've never heard of, but if you've used the audio system in your companies boardroom, your local church, a trade show or similar event,  you may very well have used their equipment without even realising it.  The Revolabs FLX is a new product, that opens their products up to a larger audience which includes SMB all the way through to enterprise size businesses.   Revolabs had heard that Epilio do a lot of work enabling Sametime with telephony systems, so sent us the Revolabs FLX2 to review.  Video review located at bottom of article.

The device comes in a environmentally friendly recycled cardboard box, and upon opening it, you are immediately presented with the instructions sheet for connecting the device.

After removing the instruction sheet, you're can see the core components for the package, the wireless handset, the wireless speaker, the charger station and the wireless microphones.

The next step is to connect everything up.  The wireless microphones, handset and speaker sit in the charger station, which is connected to the power and the base station is connected to a power supply and your PC/audio system, bluetooth device and telephone system (see video for connections).

The unique thing about the Revolabs FLX setup, is that the speaker and microphones are all wireless.  What this means is that you can give a microphone to someone at one end of the table, and a microphone to someone at the other, and put the wireless speaker in the middle or anywhere else you want.  This avoids the situation I often hear or see, which is a speakerphone that has been placed right beside the projector with the cooling fan blowing on it during the entire conference call, leading to a pretty miserable experience for the person attending the call on the phone.  In the review system I was provided with, I had a table top microphone and lavalier/lapel microphone.

The base station that does all the work, can be placed on a shelf somewhere or in a cupboard, it can connect to your telephone line, a Bluetooth device and a device that has audio input and output.  In my case, I connected the device with my regular telephone land line, my Bluetooth phone (iphone)  and connected it to my PC for use with IBM Sametime, Microsoft Lync and Skype.

Connecting it to your phone line is a just a case of plugging in the supplied phone cable, and connecting it to your phone jack.  When it's connected, the handset immediately shows the phone line as being there, and you can now make and receive calls using the handset.  Audio quality as you'd expect from a high end audio company was very good.  The handset has an easy to read screen, provides a list of missed or recently made calls, has a directory for storing phone numbers and options to configure various settings.  Sometimes for my big fat fingers the buttons felt a little small, but they always worked, and I got what I expected when I pressed them, so there wasn't really a problem.

Bluetooth pairing was simple using the handsets menu system.  Unfortunately, you can only receive calls, or join existing calls using bluetooth, you cannot use the handset as a dialer for your Bluetooth device, so if you want to join the call using your Bluetooth phone, you have to dial the call using the phones keypad, not the Revolabs FLX handset.  In most cases this won't be a big issue, in the future as more companies move towards replacing desk phones with mobile phones, this might be a missed feature.  That time is a long way off though, and I'm sure Revolabs could address that if it became a big demand.

Connecting to my PC proved a little difficult, and it turned out to be an issue with my laptops audio system.  If I connect a mono 3.5mm cable to my microphone socket on my laptop it turns out, my laptop won't record audio from it, the cable has to be a stereo cable.  The sockets on the Revolabs base station are mono, so I was going mono to mono. Using a mono to stereo converter cable solved my issue.  My desktop PC didn't experience this issue, and it turns out it really depends on the chipset in the machine, or driver, as there were even differences between similar PCs, but made at a different time.  Once I had connected the device to my PC, I tried it on IBM Sametime, IBM Sametime with SUT, Microsoft Lync and Skype audio calls.   The quality, as with Bluetooth and the phone line was excellent, with the PC audio it is even clearer than the phone line due to the much higher quality codecs used over the ancient phone system.  The device doesn't have any specific plugins for Sametime or Lync, like some of the Plantronics devices for example so is purely interfacing with the PC as a MIC and Speaker, so this means if you mute the device on the PC that isn't reflected in the handset and vice verse.  There is currently a USB socket on the base station and charger station, but this does not interface with the PC, in the future it would be great if that could be used as the audio connection, and also to provide a method for updating the handsets address book from the PC.

One thing that is really nice about the Revolabs FLX2, is the ability to merge audio streams, what does this mean?  Imagine you're on a Sametime phone call, using the PC audio connected to the Revolabs device, and the telephone rings, well now you can answer the phone and the Sametime calls audio and Phone calls audio are now merged, so you can continue to hear and speak to the Sametime person, and telephone connected person, but more importantly, the Sametime folks and telephone folks can also hear and chat to each other.  The mixing levels between the line scan be controlled by a menu on the wireless handset.

One thing the Revolabs has going for it, is certainly it's looks.  Everyone that has come by and seen it sitting on the table have always asked "Sweet, where's mine?"  If you're a company that has spent a small fortune on your conference room table, this thing is not going to look out of place if it's made from glass and metal or is 200 year old antique mahogany.  It's a really nice, classy looking device.

Overall I was very impressed with the device.  It's has an attractive unique design, offers great audio quality which is really what matters and a number of connection options.

Whilst it's not easy to demonstrate a speaker phone system on video, I've attempted to do just that with this video review.


Gravatar Image1 - like it but appears expensive ?

Gravatar Image2 - Ethernet cable is for using it with ip pix with a sip connection. Bluetooth will store multiple devices for pairings, clumsy when trying to switch.

Gravatar Image3 - Hi Carl,
Great piece. I am considering using this unit in a mid sized conference room. A basic question I had when looking into this was can I add more Mic's? Do the bluetooth devices added to the call actually act as microphones? Could you add any bluetooth microphone for that matter? I was shocked that between web searches and installation manuals, I can't seem to find these details.
Thanks for the review.

Gravatar Image4 - Connected my FLX to my Avaya IP Office system. Easy installation and works great. Excellent addition to our newly renovated conference rooms.
