Digital Hybrid Wireless Belt-Pack Transmitters
Rio Rancho, NM 3
transmission. Because it uses an analog FM link, Digital
Hybrid Wireless
enjoys all the benets of conventional FM
wireless systems, such as excellent range, ecient use
of RF spectrum, and long battery life.
Servo Bias Input and Wiring
The input preamp is a unique design that delivers audible
improvements over conventional transmitter inputs. Two
dierent microphone wiring schemes are available to
simplify and standardize the conguration. Simplied
2-wire and 3-wire congurations provide several arrange-
ments designed for use only with servo bias inputs to
take full advantage of the preamp circuitry.
A line level input wiring provides an extended frequency
response with an LF roll-o at 35 Hz for use with instru-
ments and line level signal sources.
DSP-controlled Input Limiter
The transmitter employs a digitally-controlled analog
audio limiter prior to the analog-to-digital converter.
The limiter has a range greater than 30 dB for excellent
overload protection. A dual release envelope makes the
limiter acoustically transparent while maintaining low
distortion. It can be thought of as two limiters in series,
connected as a fast attack and release limiter followed
by a slow attack and release limiter. The limiter recovers
quickly from brief transients, so that its action is hidden
from the listener, but recovers slowly from sustained high
levels to keep audio distortion low and preserve short
term dynamic changes in the audio.
Recorder function
The SMWB has a built in recording function for use in
situations where RF may not be possible or to work as a
stand alone recorder. The record function and transmit
functions are exclusive of each other - you cannot record
AND transmit at the same time. When the unit is trans-
mitting and recording is turned on, the audio in the RF
transmission will stop, but the battery status will still be
sent to the receiver.
The recorder samples at 44.1kHz rate with a 24 bit
sample depth. (the rate was selected due to the required
44.1kHz rate used for the digital hybrid algorithm). The
micro SDHC card also oers easy rmware update capa-
bilities without the need for a USB cable or driver issues.
Compatibility with
microSDHC memory cards
Please note that the SMWB and SMDWB are designed
for use with microSDHC memory cards. There are sev-
eral types of SD card standards (as of this writing) based
on capacity (storage in GB).
SDSC: standard capacity, up to and including 2 GB – DO
NOT USE!
SDHC: high capacity, more than 2 GB and up to and
including 32 GB – USE THIS TYPE.
SDXC: extended capacity, more than 32 GB and up to
and including 2 TB – DO NOT USE!
SDUC: extended capacity, more than 2TB and up to and
including 128 TB – DO NOT USE!
The larger XC and UC cards use a dierent formatting
method and bus structure and are NOT compatible with
the recorder. These are typically used with later genera-
tion video systems and cameras for image applications
(video and high resolution, high speed photography).
ONLY microSDHC memory cards should be used. They
are available in capacities from 4GB to 32GB. Look for
the Speed Class 10 cards (as indicated by a C wrapped
around the number 10), or the UHS Speed Class I cards
(as indicated by the numeral 1 inside a U symbol). Also
note the microSDHC Logo.
If you are switching to a new brand or source of card, we
always suggest testing rst before using the card on a
critical application.
The following markings will appear on compatible
memory cards. One or all of the markings will appear on
the card housing and the packaging.
