<DIV><FONT face=Arial size=2>Has anyone tried the gentner control software under
vmuser (windows virtual machine) on linux yet? I'm told that ANY i/o port
fully supported by linux is also supported under vmuser....not to mention that
if the windoze program hangs the virtual machine, you just close the window and
restart the virtual machine.</FONT></DIV>

<BLOCKQUOTE cite type="cite">1. Can the AG control workstation share control
of the Gentner with a<BR>Crestron or AMX system? Is the "control computer"
used for anything other<BR>then control of the Gentner/audio mixing? If we
are using Crestron or AMX<BR>could we use that in place of the current
control software?</BLOCKQUOTE><BR>The plan for the control computer is that
it'll switch over to being a Linux box when we get Gentner control software
that doesn't require Windows (this likely means that we'll be writing some...
protocol is very well defined by the Gentner documentation). Then we can do
things like gate rat transmission based on Gentner mic gating.<BR><BR>We also
plan to move control of the display machine to this box, doing things like
video layout, tool startup, and the like remotely. Ideally we would control
the whole node from the one machine so that we can quit the switching back and
forth that is currently necessary.<BR><BR>(I envision an audio control panel
that has a row of controls, one per mic, with level meter and gain adjustment.
It'd also have a row of controls, one per remote source, again with a level
meter and gain adjustment. This application would be the merging of the
Gentner controller with remote control/monitoring of the rat running on the
audio box. All eminently doable, just requires time to build it).<BR><BR>
<BLOCKQUOTE cite type="cite">2. Is the Gentner a capable overall mixer, or
would we still need a Mackie<BR>mixer for more generic use of the
room.</BLOCKQUOTE><BR>Depends on what you're doing. All your microphones will
have to go directly into the Gentner no matter what, so that echo cancellation
and ambient noise detection work properly. The Gentner has a number of other
inputs (I think 4 more line level inputs, and 8 outputs on the AP400. The
audio box takes one input and output, or two for stereo (that we want to
support at some point, and the speakers take one or two outputs.<BR><BR>
<BLOCKQUOTE cite type="cite">In the agspecs-new-colored.ppt document it
lists: Mackie, Biamp, Intelix,<BR>and Voicecrafter. From my reading of
the Gentner literature, it claims to<BR>do all of this - true? (We
will probably add a Mackie in anyway, so we can<BR>mix in what ever comes up
a little easier, but I was wondering if it
was<BR>necessary.)</BLOCKQUOTE><BR>Wow, I forgot about those slides :-). The
gentner pretty much rolls the functionality of all those boxes up into one
box. <BR><BR>As far as adding a Mackie, that'd be fine in the mixed-purpose
room. The way I'd use it is to connect its output to a Gentner input, and mix
it into the speakers with the Gentner. I'm curious if this is sufficient for
your purposes.<BR><BR>Also wrt general purpose use, Gentner sells an IR remote
control for the AP boxes. I'm not sure how it'd play with AG control stuff,
however, since I think the IR receiver plugs into the Gentner serial control
port.<BR><BR>
<BLOCKQUOTE cite type="cite">3. Is the telephone interface used much for AG?
</BLOCKQUOTE><BR>In the current network environment, we use it fairly
frequently to patch around lossy network (which causes great badness with the
audio).<BR><BR>
<BLOCKQUOTE cite type="cite">The AP800 has some appeal<BR>over the AP400
because of the additional inputs and outputs, but you loose<BR>the telephone
interface. </BLOCKQUOTE><BR>You can fix this two ways. If you want a *lot* of
in/out, you can cable the AP800 to an AP400 and gain four more mics, a bunch
of I/O, and the telephone interface. You can also cable in an AP10 which is
just the telephone interface.<BR><BR>By cable in, I mean the gentner private
digital bus, which provides a couple internal mixing buses for traffic between
boxes. <BR><BR>Hope this helps,<BR>--bob </BLOCKQUOTE></BODY></HTML>
