<p>Got a reply on a couple of your questions.</p>
<p>1) The ETC specs say you can have 10 fixtures on one 20A 115
circuit. This might vary depending on the model you're
selecting. I'd stay below that some myself.<br>
</p>
<p>2) Why not simply put a switch back stage for each circuit? Why
get all complicated and expensive? Is it really necessary to have
remote control?<br>
</p>
<p>3) Proper cabling per DMX specs should be immune to outside EMF.
Yes you can use mic and various other cables, but they don't
always work. Stick with the DMX spec. Question management on
why they are allowing inexperienced installers to do the DMX
cabling. At a minimum insist the contractor subcontract that
part to trained installers. <br>

1. How many units can be powered on a single 20 amp circuit?<br>
2. I've been told some relays will be necessary to turn the
units<br>
completely off when not being used, rather than simply
turning them down<br>
to zero. True?<br>
3. Since the power cables may be somewhat near to the DMX at
certain<br>
points other than at their terminations, is there some
shielded DMX we<br>
should use? Installers in this building will not have any
experience with<br>
DMX cable and we will need to be specific about what to use
and how to use<br>
it.<br>
4. Are there wall panels that will be able to run these S4
with some<br>
simple programs? We'd also like the capability to plug in a
board to run<br>
the lights.<br>
