Tips for Users

freezer bags are a great protector for your three primary components.
If you don't have a carrying case, most shaving kits are just
the perfect size. Available at most discount & department
store luggage departments.
When packing at the end of engagement, I find it works very
nice to gently (avoid tight wrap due to stress on the small
wires and connectors) wrap the cord around the transmitter and
secure with rubber band. Freedomike mini system owners can contact
me for 4" x 7" bubble bags that are wonderful protectors
to use along with freezer zip bags.
When practical, use your own new connector cables to meeting
place wall plugs. Sound cables in most all venues are older
and static/pops are generated by the dust and smoke that has
been accumulated. This is particularly true when using professional
XLR three prong plugs.
Big hint: We have found a small three way XLR splitter connector
that can be an event saver for speakers. Most venues have only
two input plugs in the wall for sound. When these are both in
use (podium mike and other long cord mike) you need a third
for your wireless. This connector allows you to easily add a
third input with a quick plug switch.
The new pocket size digital recorders you see advertised on
my web site have
totally changed / revolutionized the recording world. The following
were written about using audio cassette. With the new inexpensive
recorders you can store over twenty hours on one postage stamp
size card in
small 3 ounce pocket recorder. These recorders will give a direct
your computer or other hardware to produce high quality cassettes
media. Software that is included is loaded direct into your
computer to be

Another "Y" connector can be used from your line output
from wireless to feed two tape decks. This is a handy way to
make back up tape copy as you speak. A great help in case one
tape deck fails. Also, with this idea, we will put a C92 in
one deck and C62 in another to catch any overlap when tape turn
over is necessary. DAT recorders are very good when longer programs
need to be recorded uninterrupted, also great for sharp editing.
We are always asked about tape length and need for turn-over
assistance when the tapes are not long enough for your session.
Two solutions: Show someone how to do simple tape turnover when
it is near the end. They might give you a finger up signal from
back of the room when you are nearing the end. This will allow
you time to find a smooth "break" point to ask audience
for questions or ask them to write down something. That is the
que for turn over. My best luck has been just to watch a clock
that I have set to just tell the lapsed tape time and I do my
own turn over. My deck will be off to the side on a small table,
shielded from audience view by books or other material.
There are some newer tape decks that have two decks in one shell.
They are not like a portable but yet light weight. I would not
hesitate to carry mine in a sports bag on the plane. The advantage
is this unit has auto reverse on both internal decks.
I can put in one C62 and another C92, now I am covered when
the tape reverses because anything lost by one deck for those
three seconds will always be on the other tape.
A wireless microphone system usually has stronger volume than
the podium dynamic microphone. Therefore, you may want to find
the master volume control on the wall or possibly in a closet
at most meeting locations. You can turn the master volume control
down slightly to keep your wireless from being too loud which
can create squeal or feedback. Most hotel set up people and
food captains know how to handle this volume issue if an a-v
person is not available. Be aware that most meeting locations
use an outside service for all audio visual. Your wireless microphone
is their competition due to the high rental prices now charged
($50 to $100 a day).
Stories sometimes come my way about difficulty in union venues.
Freedomike owners have all battery operation and are therefore
not plugged into the room electrical at all. This can overcome
some union objections, since you are only plugging into audio.
If you are only using your system for recording you are out
of union conflict altogether as you operate completely with
Be sure to arrive extra early to test your wireless system and
do your hook-up. I find that many speakers rely on house people
to hook up for them. That is okay, but I recommend you become
proficient yourself, since some hotel staff do not have a clue
about this kind of equipment. It is simple when you have done
a couple of hook ups yourself. When I walk in the room it takes
about 50 seconds and I am "on the air" with my wireless.
I don't want to wait around or search for help.
Remember, your "on" light will go from bright to a
dull glow if battery is marginal. Be sure to carry spare alkalines.
Immediately after Christmas Holidays the big battery sales happen.
Fresh Alkalines should have a couple of years of shelf life.
If you live in a very cold area keep batteries stored inside
the home or office. Go to the big mass merchandisers to catch
these bargains and buy several to last you a year. Don't forget
to put a fresh one in your smoke alarms since they usually use
the same 9 volt size.
I am frequently asked about interference with other wireless
systems. That has NEVER happened to me in seventeen years and
is a very remote possibility. There is a higher possibility
of this when using equipment that does not employ the three
prong (XLR) connectors out of the system. There are several
frequencies assigned for microphones and manufacturers attempt
to avoid "stepping on" others frequencies. Lower priced
units are not able to focus on their own match with high reliability
and are more subject to outside interference. Some of my customers
work with another speaker and we have made sure they have different
frequencies. In some instances a speaker may want a hand held
and lavaliere microphone. In that case they know that both should
not be on at the same time on that same frequency.
If you want a "roving" microphone, the most economical
way is to use the meeting room hard wired microphone for that
second microphone. The perfect scenario is to own two wireless
systems and use one for hand held "roving" and your
own lavaliere or hand held.
Be sure to keep a few fresh ALKALINE batteries. If you do half
or full day sessions, change the battery at break time. (Your
battery appreciates the time to rest and you will save some
dollars in replacement.) Those of you who have the new mini
CR175 receiver should be aware that they are reliable to only
8-10 hours. When convenient, your wall power is more economical.
This compact unit was designed to velcro multiple units to the
side of a mini-cam for television stations and TVproduction
companies. Your transmitter alkaline is good for 12-14 hours.
To reduce risk of loss most find it is best to keep antenna
attached to receiver and microphone attached to transmitter.
Some owners of the M175 transmitter have not noted that the
microphone screws into transmitter base to keep it from pulling
out. Just a gentle turn will secure the plug. Please do not
twist with pressure.
Please feel free to contact me by email with any wireless or
recording related questions, regardless of your own wireless
brand. We can also help with LCD/data/video projector questions.
Our direct line to engineers in both fields can be helpful.
