[AG-TECH] Echo Cancellation

[Joe Reitzer]

Hi all,

We have both Polycom/ASPI's and Gentners here at TRECC
(3) - EF2280
(2) - XAP400
(1) - AP400

I find that the Polycom EF2280 system is by far the better system in my 
opinion.
I have an extensive audio recording background and find that the software 
for the Polycom/ASPI's  Conference Composer provides more control, has a 
better interface, etc...  I find the Gware software clunky in comparison to 
Conference Composer.  Ahha - conference composer does have a little greater 
learning curve - somewhat of an understatement.  But once past that point 
it is very sophisticated software and can do a lot.  The one thing that 
pops in my head as a major difference is being able to see all inputs with 
active level metering.  This is a serious software package and if you know 
little about the fundamentals of audio engineering then you might consider 
the Gentners.  Overall - from an end result - the participant of the AG 
session - there is no difference, they both do what they are designed to 
do.  It really is choosing Apples and Oranges.  Buy what your budget 
allows, Gentner software is simpler to use but not as robust as 
Polycom's.  Once you have experienced Polycom's conference composer 
software and can appreciate it - this is where the difference lies.

That is my 2 cents,
