[AG-TECH] Microphone recommendations

[Vine, Derek A]

I have had some experience with ceiling microphones in various Polycom
conference rooms, and have not really liked the results.  When all is
working as desired, the quality and clarity is very nice, a few mics can
cover a 25 person room.  The biggest thing that you have to watch out
for is the HVAC system in the room.  With the units I have used,
whenever there is a conference in the room, the air exchangers need to
be turned off so that it does not sound as though there is a tornado in
the room.  Then, all of the participants complain that they are getting
hot and the whole thing starts over again.  As for what to do about your
issue with not wanting cords all over the room, I wish you luck.

Jeremy,

 

My 2 cents from experience is that wireless mics are an extreme pain to
maintain due to battery consumption and also to control the appropriate
use and placement and audio... balance? If at all possible, wire them
for lower maint. particularly if they receive a lot of use. Wireless is
much more expensive as well, but they are convenient (it would seem)
until you begin dealing with batteries.  Also, if they're wireless and
the mics are not in a fixed point then you have audio issues to deal
with with microphone placement- including the famous picking up a
wireless mic and holding it like a "StarTrek" communicator... <shudder>.
Perhaps it's just me, but i like it if my users can NOT physically move
the microphones that I've so carefully balanced for the acoustics in the
room they are in.

 

I feel your pain on the wires though and in particular the microphone
situation. Newer rooms here they don't want to have "fixed" mics on the
tables and the tables themselves aren't fixed either (i.e. can change
room config in a few minutes). I know that Jason Bell had demonstrated
at SC Global his success at incorporating ceiling microphones into his
room infrastructure. Perhaps some audio folks can comment on microphone
placement and installation a bit for new installations.

I've been assigned to design and install AG systems in several

existing conference rooms for different departments here on campus.

One design they all agree on, is the lack of or sparse use of cables.

The one portable AG node I built several years ago is not pleasing to

the eye at all because of all the cables.

 

I'm interested to hear if anyone else has built or is using wireless

table top microphones, or  a combination of wireless microphones with

built-in echo cancellation.

 

Any brand recommendations?
