B3-CMIC-2
B3-CMIC 2 Channel CISCO mic interface Box
Correct PICTURE COMING SOON!!
If you have ever had to install a Cisco codec then you would know all about the supplied mics and their cable. Its super tinsel cable that is almost impossible to terminate. It also uses 4 pole mini jack connectors. This box allows you to simply extend the mic cabling without cutting or joining or doing anything else that may be an additional point of failure. It also means that if you have to swap the mics out for any reason its a simple unplug rather than a complete snip and start again.
The unit has 2x 4 pole minijack sockets connected to 2x 4 way mini Phoenix connectors. This gives any easy way to break out the wiring to a 4 core screened cable or even a CAT5 (not recommended however as that screened cable is screened for a reason !)
So now that you have you 2 lovely mic leads supplied by the above box, your going to need to get them into the codec somehow. This box makes it easy at the other end as well.
By selecting the B3-CMIC-C version you get 2x 3.5mm 4 pole extension cables and a connection interface box to allow you to terminate your audio flying leads and convert them back to a 4 pole connector, then connect them straight to the codec.
The cables are 50cm long allowing the interface box to be place above or beside the codec. The plugs are colour coded and heatshrink labelled.
This allows your installers to install and terminate fully while the codec is on order.

Why a big USB connector ?
We had an option of a standard B type USB or a surface mount Mini B type. The Mini B type would have been easier for us to design with as it has a lower profile and a reduced component size, but what we have discovered is that the smaller connector with its tiny surface mount pads is not very good at handing high levels of insertion or twisting force like you would find in a unit that was going to be fumbled with in the roof of a venue trying to plug it in in the dark.
Is it safe to connect to any USB port ?
We use the USB port only to power the device, so it is safe to connect to any standard USB port that provides 5v power. Ideally it should be connected to a regulated 5v output that you would trust to power a USB device. Current consumption is 42mA at 5v DC so it will not cause any issues with loading down a port. All USB output ports have to be able to supply a minimum of 100mA before the device has to start negotiating for more.
There is no risk to any device the box is connected to as the USB port does not have the data lines connected.
Do you publish the serial protocol ?
Sure Do. You can either get it from the Downloads Tab above or click here – B3-RLY2 Protocol v1
