Looks very interesting! With eight mic preamps on the Deva V, inputs
seem as flexible as a normal mixer.
How many headphone amplifiers are available? If there are at least the
three (monitor, boom1, boom2) usually needed from a dedicated panel,
then this control surface could be very beneficial.

Fw questions about the fusion Glenn.
Could fusion play all tracks at ones (files witch come from the deva 4,5)
, 4 tracks only ,( the first 4 ) or there will be way to play the 5-8 , 9-10
separately for post, does it recognize the Zax files as well?
does it would be available with internal dvd ?
The internal transmitter , are you planning it will be detachable type (
slot in))with fast connection or as another internal board inside the
recorder?
thanks

Glenn,
Here is a suggestion for the DevaFusion that will make it more useful in
today's ever expanding world of Digital acquisition.
The 2 Channels of Audio Plus Time code is a great Idea, but needs to be
coupled with a Tri-Level Sync signal (perhaps generated in the receiver)
that is locked to the Time-Code. This setup could be a money and Life-saver
for those of us now facing multi-camera shoots with Sony F900 or F950 HD or
Panavision Cine-Alta HD cameras used in so many TV shows these days. It
could eliminate the Lockit Boxes now used for TC on these shoots plus allow
transmission of Good quality audio to 2 tracks on each HD-Cam and eliminate
the need to Jam Lockit Boxes since the Master TC would be transmitted from
the Fusion.
Most of the newer Sony Cameras will not Successfully utilize external TC
input unless it is locked to the Video Frame rate by External Tri-Level
Sync. Not having TC that is tied to the camera's Sync will cause Deadly
Green Flashes in the Tape upon playback at various intervals. Of course
this would require some additional code or circuitry in your receiver in
order to generate the Tri-Level Sync, so I understand if you think it is not
economically feasible. But if it could replace a $900 Locit box with a
minimal addition to parts on your receiver it would definitely clean things
up on the camera end in terms of things that have to hang off the camera.

I understand the desire to do away with the Ambient Lockit or Deneke box on
the camera, but my feeling is that no matter how reliable a WIRELESS link
proves to be, relying on it to provide the crucial timecode WITH sync to the
camera is not going to fly. Once the deadly green flashes problem was
understood, I have found great reluctance to even have an Ambient Lockit box
used (for fear, real or unwarranted, that the physical connection to the
camera may be bad resulting in un-usable images). This phenomenon seems to
have driven many to seek a solution (to matching timecode when using double
system) that does not involve ANY connection to the camera for timecode or
sync.

I've done a couple of 24P jobs where, at Sony's request, all the cameras ran
their own internal record run time code. They were not locked together or
to the Deva in any way. So there were no tri-level sync or 'green flash'
issues. Audio sync was provided by sending Time of Day time code from the
Deva to the cameras via Comtek or jammed sync boxes(which didn't have to be
tri-level) and recorded on Audio Channel 2. For back up, or for some action
shots where the camera operators wanted no peripheral devices, we used
Denecke slates.
Until HD cameras evolve to the point where time code is just a reference and
not a sync source, this seems the easiest and safest way to go.

Yeah, I know how they get about stuff connected to the camera. I was just
trying to figure out how this new Deva Fusion's timecode feature could be
used with Digital Cameras.. You can't use it to continuously send TC to the
camera because of the Genlock issues. I just thought if it could eliminate
another box it would be a valuable addition and take some sting out of the
desire to hang the receiver on the camera. Of course the Tri Level. Sync and
TC would have to continue to run un-interrupted even if the wireless signal
is lost.
Perhaps it could be used in conjunction with the Lockit Box. Feeding the
time-code jam input on each Lockit Box. Then have a switch on the DEVAFusion
to send a burst of code now and then between takes. That would keep the
cameras jammed (wirelessly). You could only send a burst between takes
because according to ambient, sending TC continuously into the Lockit will
cause it to re-jam every 5 seconds and can cause hiccups in the output TC
every time it Jams. Not good either.
William Sarokins Idea of Letting the Cameras Run in Record-Run mode and
putting LTC on one of the Audio Tracks would work. Except on the Panavision
cameras you only have 2 audio tracks available and would have to give up one
of your 2 wireless channels in order to record the timecode.

Our receiver will output time code continuously. If the signal is lost
or glitches the receiver has a "Flywheel" type effect as far as the
time code is concerned.
Can we make a RX with a tri level sync output? Of course we can. If
the market wants it, it shall be done.
Best wishes

The control surface with the Deva V have 8 analog outputs. Two talk
buttons are available for talkback. The outputs for this are balanced
XLR but I think I will add a headphone out Jack for each of the 2
outputs.
Thanks for the feedback.

That's great Glenn, I think it would add additional value to the product and
expand its market beyond the ENG world to Multi-Camera HD shoots. Just don't
delay the delivery of the Deva IV & V in order to implement this new idea on
the Fusion.
