DSM* Headworn or HRTF Baffle Mounted Microphones fully utilize
natural psycho-acoustical cues involved in normal spatial hearing
of ambient surround sound. DSM is NOT a traditional Binaural
in-ear recording method. As such, DSM mics DO NOT have
the headphones only playback limitations typical of Binaural "in-or-very-near-ear"
microphone methods. DSM mics faithfully allow consistent emvironment
recordings with precise virtual reality (VR) surround imaging
for both headphone and multi-channel stereo/surround speaker playback
with 'you-are-there' live realism. Also, unlike binaural sound, works
well when presented in lowest denominator monophonic as is common
with radio productions.
DSM recording's result in stereo/surround
multi-channel environment sound perceived as 3-Dimensional,
virtually realistic & very convincing; retaining the full emotional
effect of all live sound experiences.
The DSM method of
ambient sound recording has proven extremely effective in capturing
the total sound spectrum of: voice, vocals, musical instruments
large & small, natural background ambient, staged music &
theater performances, ENG and news interviews, sound effects (EFX),
music & sound samples, point-of-view (POV) film & video
location sound, and sound for virtual reality (VR) media program
& game projects.

type cord/leash molded construction with rubber loops for versatile
'stealthy' head mounting.
allows easy and secure mounting to many types of headworn apparel
such as "eyeglasses mic", sweatband, hat or cap, mounted on the WHB windscreen headband or DSM-GUY or LiteGUY or VideoGUY
'dummy' head HRTF baffles for extraordinary stereo recordings.
recording method uses ONLY the head's HRTF effect (NOT
the ears as in Binaural!) to naturally record full spectrum multi-channel
surround & mix-to-mono media capability 3-D ambient sound.
personally worn, DSM mics will not interfere with normal hearing,
vision, and are very resistant to generating any noise from mechanical
Mics are a unique (patented) type of 'Spaced-Omni' HRTF BAFFLED Mic that produces recordings with

mic, but a different kind of HRTF Stereo-surround ambient mic /

Suggested 2011 2-Channel Stereo-Surround Configured Portable System: DSM
mic powering 24bit flash recorder + most appropriate choice of DSM mic
remote location limited recording time with long runtime external
deck power systems.
recorder mic inputs do not power DSM mics, and/or are too noisy for some
purposes. These require at least DSM mic powering
and often only external preamp solves
digital deck's too noisy mic input issues.
costing solution for some deck input noise issues is LINE level audio
from external PA-3SX (-U)
or more featured PA-24
(series) preamp models.
Record IT in Stereo
Exactly Like you Hear it...
No Limits..... NO Excuses . . .
or HRTF Baffle mounted, DSM makes it easy to get it right the first
time, AND is the only totally commercially compatible stereo MIC that
consistently records everything in the environment exactly like you
hear it at the MIC position.
NO MIC coloration distortions or frequency bandwidth limitations;
NO nasty surprises later in post edit.
A most consistent perfect for recording any environmental sound desired.
RECORD the full rich sounds of: Guitar,
Vocal Groups of all styles, Live Performances of any kind, 2-Channel
studio mix tracks, and collect Keyboard samples of anything anywhere
with any recording deck, laptop external soundcard, or camcorder with
line/mic inputs. It just can't get any easier than this.

looking for a battery pack for running so many hours,
and know the external
pack internal battery size, do the math with:
Voltage x Ampere Capacity = Watts (pack
EXAMPLE: BC-MR4 for KORG
MR-1 deck shown at right. This external pack has over
35 watt capacity using 4 C alkaline cells that when divided
by 2.5 watts needed by MR-1 = ~16 hours runtime.
type of battery pack 'recharges' in seconds anywhere
with fresh cells inserted.
the selling retailer does not list the pack's internal battery
voltage and ampere capacity, but
try to find this going to the pack maker's web page technical
description for best chance of finding this. Most of these
external rechargeable packs use just ONE 3.7 volt lithium
battery at some ampere capacity.
hours runtime is far more than most recordists need
for doing an evening concert or session, and then returning
home to recharge.
much longer battery runtime is
exactly what's very needed for those doing days of recording
in remote locations, where recharging external packs is not
so practical, or those just wanting maximum recording runtime
capacity, and extra reliability of alkaline cells so remote
location powering on batteries is 'never a problem.'
and powerful, alkaline flashlight cell type packs are, they
seem not environmentally kind because they're using
up non-rechargeable cells that end up in a landfill!
MR-1 requires ~2.5 WATTS power
available watts at 5 volts pack output will be (10%-25%) less
than that, but you'll know at least ideal run time by dividing
external pack watts by 2.5 deck watts. So be conservative in
estimated running time from any pack until fully 'rundown' tested.
New packs need 2-3 use to ~60% remaining, recharges to fully
to maximum capacity, and then will last up to 2 years before
losing 20% or more capacity/runtime ability. So SUGGEST
best to BUY NEW having 50% MORE capacity than expected to
is less an issue with
packs using much larger capacity D cells having 35-50 Hr deck
runtime, needing 'refreshing' ONLY every
year or two(!) if used every month for recording one
or two events.
interesting is most lithium rechargeable pack batteries fully
work same 1-2 Yr. length of time,
and have lost enough reliability/capacity for owners to
be disposed for cheaply getting
in many use situations, about the same burden
on the environment using either type battery.
