The Truth About 32 – Part 2 of 2

Last week in Part 1 of my blog, I discussed a recent Revolabs project that had 6 rooms, and needed more than 32 channels of Revolabs wireless microphones, (32 is the limit in North America according to all our documentation). Here is Part 2 of the blog where I reveal the solution to use 40 channels simultaneously:

With careful consideration given to existing RF interference, designing adequate distance between properly configured receivers, and ensuring that a sync bus cable is installed between units, we can overcome many potential issues.   In addition, by clearly defining required applications, and explicitly excluding those that will not be supported, we can limit channels to a manageable number. 

By leveraging our team, the integrator not only reduced design time, but also mitigated their risk (to some degree) by relying on the manufacturers’ recommendations.   The proposal was submitted and shortly thereafter, approved by the client. A project timeline was outlined and a date was set for the onsite commissioning.   

Upon arrival for the onsite commissioning, I discovered that an additional receiver had been added to the Combinable Room for a total of 48 channels.  First, we checked microphone pairings, configuration settings, and verified the physical connection via the sync bus.  We then proceeded to test the system by connecting all six rooms to a bridged conference call with all microphones unmuted and placed in their approximate positions.  Each microphone successfully passed audio, with no drop outs or interference, for the duration of the call.

All 48 wireless microphones, in six large conference rooms, in close proximity to one another, were operating simultaneously and functioning properly.  Our collective due diligence and international project coordination had paid off. 

With the conference call still connected for testing, we sat down for lunch.  I had ordered a six-inch sub, but our British friends had ordered me a foot long.   I ate the whole thing, and then smiled.   We may order a six-inch, but sometimes we don't mean it.  Just like 32, sometimes we really mean more!
