SMART SPECTRUM™ & 70 CHANNELS
PUT NEW SABINE WIRELESS AHEAD OF CROWD
Sabine is now ramping up production for its long-awaited 2.4
GHz wireless microphone systems. Improvements since the original
concept include the ability to use up to 70 channels in a
single location. The newly named SWM7000 Series also employs
Sabine’s Smart Spectrum™ technology which provides
superior RF performance.
“Smart Spectrum moves beyond the spread spectrum concept,”
states Director of Sales and Marketing Rob Rothschild. “With
Smart Spectrum, we combine spread spectrum filtering with
a variation of FM technology to give pro audio users excellent
sound quality and strong interference rejection.”

2.4 GHz Wireless Microphone Systems |
Each 2.4 GHz receiver comes with Sabine's built-in Targeted
Input Processing: the FBX Feedback Exterminator®, a compressor/limiter,
an adaptive de-esser, and a set of parametric filters.
New on-board digital signal processing for the 2.4 GHz systems
includes Sabine’s Mic SuperModeling™. A touch of the front panel
dial brings up a choice of several well-known dynamic or condenser
mic elements. Sabine's standard capsule on the SWM7000 Series
is an Audix OM-3, with the Audix OM-5 available as an option.
In addition to the added processing, the SWM7000 series allows
users to save and recall up to 10 presets per channel on the
receiver. All front panel information is saved in each preset,
so custom settings can be retrieved for fast setups, or even
on-the-fly changes during the program.
All SWM7000 systems come with very powerful Remote Control Software.
SWM7000ND Series receivers include both analog and digital audio
outputs and allow for networking of up to 70 channels (one transmitter
per channel) using a single computer.
Long-life rechargeable NiMH batteries power the SWM7000 transmitters
and each transmitter has a built-in charger jack. Furthermore,
the convenient handheld microphone clip doubles as a charger
stand — whenever it's in the clip the mic is being recharged.
Check out Sabine's hot new system at our NSCA Tradeshow
(Dallas, Texas) booth #1118, March 13, 14 & 15.

WIRELESS COVERAGE IN ALL THE HARD PLACES
Multiple wireless mic system installations can suffer from a
variety of problems. Besides their "antenna farm," helter-skelter
appearance, there is the potential loss of signal from poor
antenna placement and interference generated by having the antennas
of different receivers too closely situated to each other.
Brett Ramage of Sport View Technologies had these and other
concerns when he began his audio/visual installation for the
new Tri-State Racetrack & Gaming Center
(Cross Lanes, West Virginia).
"We installed 5 wireless Sabine UHF systems (SWM3000) within
the 40,000 square foot gaming center," recalls Ramage. "This
is a round, all-metal construction with several large objects
that cancel out any chance of line-of-sight transmission," he
continues. Ramage overcame these difficulties by installing
Sabine's UHF Antenna Divider System (SWA4U), with extension
antennas (SWAUEXT) and antenna boosters (SWAUB).
"I am very impressed with the reception we are getting," states
Ramage. "I was concerned at first that I would have to locate
the extension antennas far away from the receivers," he confides.
"But we have them placed less than 20 feet away and there are
no reception dropouts - anywhere. We even reach into the meeting
rooms!"
"I
am very impressed with the reception we are getting."

UHF Extension Antenna
(SWAUEXT) & Booster kit (SWAUB) |
Along with
the True Mobility wireless microphone systems, Sport View installed
four channels of Power Q™ Multifunction Digital Signal Processor
and four channels of the Graphi Q™ Multifunction Digital Signal
Processor into the Tri-State complex.
Eric Ford, Information Systems Technician for Tri-State, loves
his newly installed Sabine equipment. "I cannot say enough good
things about these products," exclaims Ford. "They are easy
for any sound guy that comes in, or for me to use when I need
to. Everything is straight forward, intuitive and reliable."

Q-Tips
True Mobility™ Targeted Input
Processing
Situation:
I have 5 wireless mics out on the floor, and each one requires
different signal processing. Some of the users have gentle
voices, some booming; some like to go out into the audience
or in front of speakers; some have very sibilant voices. I’m
running out of rack space! What can I do?
Solution: Customize
the processing for each mic by using the digital signal processing
built in to each True Mobility™ Wireless microphone
receiver.
Here's How:
|
FBX
Feedback Exterminator®
| 1. |
Place
microphone & speakers in primary position. |
| 2. |
Press
& hold SETUP button on receiver until
lights flash 4 times and SETUP stays lit —
then release it. |
| 3. |
Slowly
raise gain on mixer or amp until FBX eliminates
first few feedback tones. |
| 4. |
Pause
raising gain and move microphone to another
area where it will be used. Resume slowly
raising gain. Repeat steps 3 & 4 until
SETUP indicator goes off and READY indicator
comes on. |

Compressor Settings (Typical
Vocal)
RATIO — Soft voice could be set
to 2:1, whereas a loud voice might require a ratio setting
of 6:1.
THRESH — The higher the threshold
setting, the more signal is required to initiate compression.
Ideally this should be set to reign in peak levels, and
allow signals of lower gain to pass uncompressed. Threshold
settings will depend on the nature and variety of the
signal source.
ATTACK — Short attack times usually
work well for voice. However, too strong a compression
ratio, too low a threshold, and too fast an attack may
attenuate speech consonants, which provide important intelligibility
cues to the audience, thus compromising clarity.

Compressor Settings
(Typical Guitar)
RATIO — A high compression ratio
(with gain makeup) will add sustain to held notes and
chords.
THRESH — Moving the threshold will
change the audible thick/thinness of the guitar tone,
but generally, you want to compress all the notes played.
ATTACK — Be wary of too quick an
attack, which may reduce the percussive attack of the
guitar notes.
In general, be wary of too much gain makeup, and too high
a compression ratio, which may make a noisy guitar amplifier
more objectionable. Ratio settings might range from 6
to 20:1, threshold variable, slower attack, soft knee,
output gain boosted slightly to significantly depending
on amount of compression. |

De-esser
Turing the knob clockwise reduces sibilance.
