- I have been working with and using CP Communications since their beginning when I was part of Erskine-Shapiro Theatre Technology. Michael Mason and David Goldsmith have created a terrific company and now with the acquision of Total RF and particularly Production Radio Rentals and Henry Cohen, have a world class RF department. Additionally their comms equipment is bar none including RTS and most importantly Riedel Artist Digital intercom.
Breakout dB 9 connectors from Gravatech
- A fellow Comm nerd, Jess Contreras, showed me a company that makes really nice dB 9 connectors
to terminal blocks for quick interface to Riedel GPIO in particular. Take a look.
Also I found a similar company with narrow form factor and screw lock down:
Solves the problem of connecting to Riedel.
Bruce Kraemer - provides a survey service to producers and
staging companies in TV, AV and the special event business. He lives in the Chelsea neighborhood
of Manhattan it is very easy for him to go to New York City sites to get those annoying bits of
technical information that every project needs. What are exact dimensions of that freight elevator?
How much three phase power does a venue have available? How high are the ceilings and how much do
the chandeliers get in the way? Are you looking for an art gallery kind of space, a loft, or
something off the beaten path? He can find you several choices and send you photos that might
reveal more than you can see on a venue's website. He does scale drawings so your designers
know where things really are located and has worked in almost all of the departments a show uses,
from lighting designer to Audio A1, from Intercom guru to RF coordinator, from prop manager to
event producer and technical director. His experience is amazing. Definitely look into his services.
Audioman ISO BOX - This inexpensive box
implements the BuzzBuster Transformer box shown in the drawing
but without the switches for the audio only functionality. It seems to work well. The principle is that in intercom systems
the actual audio is unbalanced with channel A on pin 2 of the connector and channel B on pin 3. The two
transformers isolate each of the pins separately and the capacitors block the dc in the intercom systems from the
transformers which would burn them up. I have not tested the transformers to verify the effect on hybrid nulling.
The transformers specified in my BuzzBuster were selected to affect the nulling of hybrids as little as possible.
look at the testing HERE.
Here is the simplified schematic of a BuzzBuster which is what is in the Audioman ISO Box.:
Intracom system - This is a full featured matrix system that runs on your
PC or Mac (Boot Camp or Parallels). Wireless First was the intercom supplier for a major corporate event which covered 5 cities
and had 6 sites with 2 in New York. Three global intercom channels were interfaced over the internet with
astonishing audio clarity. Watch a 60 second edited clip of Pete's
screen during the event and hear the audio quality HERE.
Got a network in your company or production facility? Add this (and a few DA/AD converters and relay control for
other interfacing) and you have a matrix comm system. Put a panel on every producer's laptop PC for
inter show communication across the world. This sysem has normal internet latency issues, similar to cell phones, but for
informational communication it's wonderful. Point to point, party lines, Page, monitoring, telephone interfaces, GPIO, Port level volume
control, automatic gain control on panel mic, radio interface...it's all there. Who needs all that hardware!

HME 2.5 GHz DX210 intercom system
- This is an innovative wireless intercom system. Aimed at the fast food market,
it promises to be a useful tool in productions as well. Automatic
frequency allocation as well as dual channels makes it very easy and convenient to
use. Because of the high frequency, it doesn't cover as well
beyond the walls of your venue as analog RF intercom does, but additional
antenna splitters are available to remote a second set of antennas.
Cut coax antennas can spread the usefulness over several rooms.
