Check
dance flyers for those that will have a sound enhancement transmitter
available.
Normally
the frequency to be used is posted on a flyer and at an event.

Connections
to the Caller/Leader turntable/amplifier
There
are several different connections that can be made the PA system.
This can include connection
to obtain both voice and music or just the voice. See
attached sheet for the various connection directions.
Questions:
How can we afford to purchase a transmitter as well as a
receiver?
Clubs
and/or Callers/Leader sponsored fundraisers i.e. 50:50 draws designated
for the purchase of the
equipment, and proceeds from special dances (trail-in and trail
out convention dances) are excellent ways to raise funds to
purchase a transmitter. Dancers will respond to fundraisers when they are aware of the cause,
especially one that will benefit the activity and its participants.
Purchase
of a system with a transmitter and several receivers is cheaper than
purchasing the
various
units separately. This is understandable. Some
manufacturers have systems available with 1 transmitter and 4-6 receivers,
complete with the associated listening equipment ready to set up and use.
Clubs
and Associations can consider the joint purchase of a transmitter to be
shared by several clubs
and the association and its members. It is possible and in fact
logical for one transmitter to be used several nights each week
by sharing the equipment. Why not do this, at least
initially,rather than have everyone wait to purchase their own
transmitter. This enables many more dancers to benefit immediately.
Will
the connection of the transmitter to the caller/leader's
turntable/amplifier cause
damage
to the caller's system?
NO it will not.
Callers/Leaders
and Clubs strive to provide the best sound system (amplifier,
microphone and
speakers)
they can for their dancers. Don't stop there. Take the next
step and provide sound enhancement
equipment for dancers. At least a transmitter. Those
callers/leaders who do use hearing enhancement equipment will
have to recognize that they will have to reduce the variation in the sound level they use during
their calling/cuing. If this is not done it can be very
annoyingfor the wearer of receivers - although they can adjust the
volume level on their receiver, but it is annoying to have to do this on a
continual basis.
If
I purchase a receiver can I use it in other places?
Some
of the receivers are constructed to enable people to adjust the
frequency received. It is possible with some makes to easily
adjust the receiver to hear the narrow band public sound enhancement frequency (76.675
MHz). This is the frequency used in many public
places. Ask suppliers
about the availability of this feature.
Choosing
a Sound Enhancement Receiver
This
is like purchasing any other piece of sound equipment. Determine
where and how you want to
use the receiver and the frequencies you would use. This will
assist in determining the receiver to suit your needs. How
important is sound quality? Compatibility with your activities
and needsin public places, churches, etc.?
Consult
your audiologist to discuss your hearing problems and obtain an opinion
on the possible use
of sound enhancement equipment.
Testimonials:
"Since
our caller purchased a transmitter, I purchased my own receiver.
I have the great pleasure to report that the improvement in
hearing makes dancing so much more pleasurable now that I don't have to concentrate so hard
on the words of the caller."
Dancers
comment to a caller, "It is wonderful how the calling has improved
since I got the hearing
enhancement."
Ask
your caller/leader or Club about such a system if you are having
difficulty hearing the calls/cues!

My
Experiences with a Sound Enhancement System
By Al Schaffer, Baltimore, MD
[Reprinted from the March 2002 issue of Zip Coder]
About one year ago, John Marshall
initiated a conversation with me concerning my difficulties in hearing
the square dance calls. John told me he was aware that square
dancers were generally getting to be an older representative group and
that hearing problems would impact more and more dancers. John
had already seen several enthusiastic dancers decrease their activities
or simply stop dancing because of their hearing problems.
My personal hearing problems started in my
early 30’s (I will be 69 on my next birthday). I had a stapes
mobilization operation on one ear in 1965, which resulted in some
improvement of my hearing. I eventually purchased a hearing aid
for my worst ear, then hearing aids for both ears, then better designed
aids for both ears and finally much better designed hearing aids in
both ears.
Although all of the above gave me better
hearing, nothing solved my biggest problem; that of filtering out most
extraneous sounds so that I could concentrate on important
sounds. In square dancing that means hearing the exact words of
the caller. For example, circulate, coordinate, motivate,
percolate, etc., often sounded for some unknown reason like something I
ate. I had a very hard time distinguishing the difference.
As people with hearing difficulties know,
trying to solve these problems can be an exasperating and costly
matter. John Marshall’s approach to helping solve hearing
problems for dancers was to invest in a sound enhancement system that
he could incorporate into his existing Hilton Sound System. His
choice was the Williams Sound System, a wide-band FM Listening System
that operates in 72-76 MHZ frequency band. This system is
designed for hearing assistance in places of public access to help
overcome background noise, reverberation or distance from the sound
source.
His investment in the Williams System included
a T17 transmitter, several R7 receivers and three types of earphone
pieces. His club members, who showed an interest in trying the
system, were encouraged to borrow a R7 receiver and put it in a pocket
or belt clip, plug in an earphone, adjust the volume and dance. I
tried all three types of earphone pieces at John’s dances.
I decided to purchase a neckloop telecoil
coupler that is designed for use with a telecoil equipped hearing
aid. Using a neck loop in coordination with a telecoil equipped
hearing aid eliminates the need for a wire or a device going into or
onto the ear. The neck loop, which looks like a bolo, uses magnetic
energy to transfer the electric signal from a sound source directly to
the telecoil equipped hearing aid. Years ago, when I equipped my
hearing aid with a telecoil to assist me when talking on the telephone,
I did not realize that its greatest value to me would be to help me
during square dancing.
This system is not only for those wearing
hearing aids. Square dancers, with or without hearing aids, who
choose the more conventional Williams earpiece, also get improvement in
their hearing.
My favorite aspect of using this system
is that since many Hilton turntable/amplifiers are equipped with a
voice-only jack, I can receive in one or both ears only the caller’s
voice and eliminate extraneous sounds. Music will automatically
filter in loud enough for me to be aware of it but not enough to drown
out the voice. Additionally, some Hilton turntable/amplifiers
have a backup independent amplifier with separate controls. This
feature allows the voice-only jack’s volume to be adjusted to suit the
dancers using this system. There is no negative impact on all
other dancers; only the system users are aware of the adjusted volume.
The transmitter and receiver work on FM radio
signals up to 500 feet, therefore, your location in the dance hall from
the caller becomes unimportant. Many square dance weekends use
multiple halls in close proximity. The receiver and transmitter
can be purchased with up to six FM channels. This allows up to
six halls to operate with its own frequency, thereby preventing cross
interference.
My original investment of a R7 receiver, belt
clip and neck loop was less than $200.00. The R7 receiver and
some kind of ear system would be the minimum items one would have to
purchase, if the caller has a transmitter. Since I have not found
a club or caller on the east coast with sound enhancement equipment,
with the exception of John Marshall, I added a T17 transmitter to my
equipment. My cost for the complete system was less than $900.00
and includes a spare earphone piece in case my hearing aids malfunction.
Dancing with the Williams Sound System has me
spoiled. Now, since I have my own transmitter, wherever I dance I
am self-contained. All callers seem to have Hilton equipment and
connecting my transmitter to a Hilton Sound System is as simple as
putting a jack into the proper input. I have found that all
callers know the proper input jack for me to use with their particular
equipment.
Ask your club or club caller to look into
trying out a sound enhancement system such as the Williams Sound
System. Consider getting a group of dancers, who might benefit
from its use, to volunteer helping defray some of the cost. Check
to see if your club could have a trial period as John Marshall
did. Most clubs, club members and callers will derive a benefit
from an investment in a sound enhancement system. The dancers who
need help in hearing the calls will hear better and the squares they
are in should dance better. Clubs and callers will be the
beneficiaries of happier members and a stabilized membership.
I cannot end this article without mentioning
that I have found a downside using this system. Less often can I
get away with ‘I missed that call because I did not hear it!â€.
The following paragraph offers additional
information about sound systems. ***********************************************
It would be most helpful if staff callers for weekend
consider purchasing the small battery operated (two AA’s) Williams
Sound Transmitter #PFM-T30. This unit has ten selectable
frequencies, size: 3 5/8â€LX2 3/8â€WX7/8â€H and weighs only 4.4
oz. This unit would be more suitable for those traveling by air
than the more deluxe ac powered T-17 Transmitter, because of the small
size and weight. The price of this unit is in the $320.00
range. Williams Sound indicates that this transmitter can be used
with a microphone or connected to the tape/voice output jack of the
amplifier unit through a very inexpensive Radio Shack 40db Attenuator.
