2) Clean only with dry cloth.
3) DO NOT block any ventilation openings. Install in accordance with the manufacturer’s instructions.
4) DO NOT allow foreign objects to pass through the grill face or touch the emitter
5) DO NOT install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
6) DO NOT defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades
with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide
blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet.
7) Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and
the point where they exit from the apparatus.
8) Only use attachments/accessories specified by the manufacturer.
9) Unplug this apparatus during lightning storms or when unused for long periods of time.
10) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have
fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally,
or has been dropped.
11) Use 3-inch minimum spacing distances around the apparatus for sufficient ventilation.
12) The ventilation should not be impeded by covering the ventilation openings with items such as
newspapers, table-cloths, curtains, etc.
13) No naked flame sources, such as lighted candles, should be placed on or near the apparatus.
14) Due to the potential of extreme temperatures, do not place this unit in direct sunlight for extended
periods of time.
15) While medical research indicates that the levels of ultrasound used in this HSS device do not cause any harm
to human hearing, tissue, or body parts, common sense would dictate and ATC recommends that you follow
prudent safety procedures as you would with any loudspeaker device operating over 80-90 dB SPL.
16) It is recommended that when operating the HSS emitter in “direct” mode (pointed directly towards
the intended listener), that you maintain a > 1m (3 ft) distance between the emitter surface and the listener.
17) This product is approved for Indoor use only.
18) It is recommended that you at no time aim the emitter directly into the ear canal at less than 1m (3ft) distance.
19) DO NOT store, ship or use where temperature may go below 14ºF or exceed 104ºF

Introduction/
HyperSonic™ Sound is a completely new approach to sound generating technology. It is a par-
adigm shift in sound production based on solid principles of physics. There are no enclosures,
crossovers, woofers, midrange or tweeter elements. The sound we hear is actually generated in
the air indirectly, as a conversion byproduct of the interaction of ultrasonic sound waves and the
air itself.
First, consider the fundamental operating principals of conventional loudspeakers. About a half-
dozen commonly used conventional speaker types are in use today. Whether they be dynamic,
electrostatic, ribbon, or some other transducer-based design, all traditional loudspeakers today
have one thing in common: they are direct radiating—they are fundamentally a piston-like device
designed to directly pump air molecules into motion to create the audible sound waves we hear.
As an example, a typical cone loudspeaker moves the paper cone back and forth in the air,
which directly creates the sound we hear.
In contrast to conventional loudspeakers, HSS technology produces sound in the air indirectly
as a byproduct of a completely different process. HyperSonic Sound Technology starts by pro-
jecting a directional beam (column) of modulated ultrasonic audio frequencies into the air.
However, we cannot hear these ultrasonic frequencies. The interaction of the air and the modu-
lated ultrasonic frequencies creates the audible sound we hear within the column of ultrasonic
frequencies. The sound is actually created as a byproduct of the interaction of the air molecules
and the modulated ultrasonic frequencies. The audible acoustical sound wave is caused by the
air down-converting the ultrasonic frequencies to the lower frequency spectrum we can hear.
Since the audible sound is produced inside the column of ultrasonic frequencies (which is highly
directional), an important byproduct of this process is that the audible sound can be tightly
focused in any direction within the listening environment. Unlike a conventional loudspeaker, no
sound is projected to the sides or rear of the HSS unit. This provides outstanding flexibility and
allows an unprecedented manipulation of the sound’s direction.
How is HSS different from traditional loudspeakers?
1. HSS projects sound in a tightly focused column without spreading sound in all directions.
2. HSS does not follow the traditional loudspeaker Inverse Square Law (6dB decrease in level
for every doubling of the distance from the source). This means HSS sound can travel much
greater distances than the sound from conventional loudspeakers while maintaining complete
intelligibility.
NOTE: This Owner’s Manual refers to HSS in general, however, it is detailed specifically for unit model number
S220A. This model is fully self-contained and contains audio input processing, power amplification, and an output
emitter device. It only requires a source of audio and AC power to be fully functional.

UNPACKING & INSPECTION/
Unpacking the Carton
Carefully remove the HSS device from the packing carton and gently remove any protective
wrapping from around the unit. Be particularly careful not to damage the front emitter surface
or allow any foreign objects to come into contact with the emitter surface (the silver, dimpled
surface behind the protective screen).
Items Included:
(1) HSS Directed Audio Sound System unit (model # is indicated on the rear panel)
(1) Owner’s Manual
(1) Warranty Card
(1) AC Power Cord
Inspection
Carefully inspect the device for any obvious physical damage. If there is evidence of any damage,
DO NOT plug the device into AC power and DO NOT attempt to operate the unit. Immediately file
a damage claim with the delivery carrier and contact ATC for repair or replacement instructions.
INSTALLATION & SET-UP/
Cautions on Handling
Use caution when handling the device. Be sure that no foreign objects are allowed to come into
contact with the surface of the front HSS emitter devices (the silver, dimpled surface behind the
protective screen.) If the face of the emitter is scratched, punctured, or otherwise damaged, the
HSS Sound System will not function properly and should be returned to ATC for repair.
NOTE: DO NOT remove the protective film covering the front surface of
the unit until after final installation, but before AC power is applied.

Adjusting HSS
Adjust the mounting angle to ensure that
the directed audio is focused at the
correct area of interest.
DIRECT MODE:
As explained earlier in this manual, Direct Mode
assumes that the listener will be in a direct path
in front of the HSS device. He or she will hear
the audible sound as the sound column passes
by their head. The sound will continue to travel
past them until it either strikes a surface or is
absorbed by the air (over a long distance).
What happens to the sound after it strikes
a surface? (Sorry, some basic acoustical
education is coming up…)
A number of things can happen when a sound
wave strikes a surface depending on the
surface itself. If the surface is flat and hard
(e.g. a mirror or plaster board), the sound will
reflect from the surface. Some energy will be
lost, but some of the sound will be reflected
back into the environment. The angle at which
the sound strikes the surface will equal the
angle at which it will reflect (assuming a
perfect reflector). Of course, there is no
perfect reflector so some amount of the
sound will scatter back into the entire area,
while the loudest portion will follow the
refection path.
If the surface is absorptive at the proper
frequencies, the surface will contain the sound
within the surface and little sound will be
directed back into the environment. The last
alternative is to make the surface diffusive. If
you diffuse the reflection you essentially
reflect it back into the room in all directions.
Therefore, no single reflection is louder than
all the rest.
One of the great benefits of HSS is the fact
that we can now predict where the sound
will strike a surface (first reflection) and treat
that surface accordingly. Since traditional
loudspeakers emit sound in all directions, the
audio always sounds like it is coming from
the speaker device because no matter
where
you are in the room, the first sound you hear
is actually coming directly at you from the
speaker. Now, with HSS, we only have one
column of sound to deal with.
When you consider the “First Reflection” of
the HSS sound column, remember, you can:
1) REFLECT IT! Angle the HSS device
correctly so that the first reflection is directed
where you want it to go. For example, if you
don’t want to hear the first reflection, direct it
up into the ceiling, or direct it into an absorptive
surface someplace else in the room, etc.
Also remember that sound does dissipate over
distance. Therefore, the farther you can make
the reflection travel, the lower it will be in vol-
ume when you hear it again. A good example
would be an overhead HSS unit directed down
towards the floor with the first reflection going
back up into the ceiling. If the ceiling was 50 ft.
away, the reflected sound would have to trav-
el 50 ft. up and 50 ft. back down before you
would hear it again. It may be completely
inaudible by that time depending on how loud it
was when it started, the composition of the
ceiling, and ambient sound level.
2) ABSORB IT! Make the surface struck by
the first sound reflection highly absorptive.
The better the absorber, the lower the reflected
energy. Carpet, for example, is a very poor
absorber. It will absorb some of the highest
sound frequencies, but will reflect the remainder.
Some office wall panels are somewhat better,
but still they will reflect the majority of the
energy. A local acoustical technician can
provide you with the most appropriate absorption
material for the individual installation.
3) DIFFUSE IT! Make the surface multi-layered
and multi-dimensional. The more irregular the
surface, the better the diffusion.

Selecting Location for Installation
The mounting method and installation of this HSS device has most likely already been determined
by your HSS provider. However, some background information may be useful.
The most important thing to remember is that HSS produces a beam (column) of audible sound.
It does not create a point of sound in space. If the HSS unit is pointed directly toward the listener,
he or she will hear the maximum audio volume possible. This is similar to shining a flashlight toward
someone. If they stand in the beam and look at the flashlight, they easily see the light coming from
the end of the flashlight. HSS performs in a similar fashion. If you aim the audible sound column
directly toward the listener, we refer to this as using the HSS device in the Direct Mode.
However, if the listener is not in the beam and the sound column strikes a surface, the sound
will be reflected back into the environment. What the listener will hear, is the reflected sound
from the surface. The listener will perceive the sound as originating on the reflective surface
because that is, in fact, the direction of the sound is coming from when he or she hears it.
The reflective surface becomes what is called a Virtual Sound Source. Using HSS in this mode
is known as Virtual Mode.
Environmental
Thermal: The proprietary emitter device used inside the HSS unit can be damaged by
excessive heat. The only recovery from this is to replace the emitter device. Therefore, care
should be taken to avoid exposure of the emitter surface to direct sunlight for extended
periods of time or installation of the unit in other applications where the ambient temperature
could potentially cause damage.
Humidity: While the HSS unit is not subject to permanent damage by high humidity, it should
be protected from direct rain or water—the same as you would protect any electronics
device. If the unit is moved from a cool to a warm environment quickly and moisture condens-
es on the emitter units, it is recommended to wait until the emitter surface has dried before apply-
ing power. The moisture on the emitter surface adds extra mass to the sensitive film and will
detrimentally affect the performance.
Vibration: Your HSS unit is not particularly sensitive to vibration. Use com-
mon sense regarding installation as you would with any electronics device.
Dust and Dirt: The sensitive piezoelectric film used in the emitter produc-
tion is sensitive to added mass (weight) of any kind.
Mounting
(optional accessories)
Multiple mounting bracket options are available for HSS devices. The vari-
ous bracket assemblies allow maximum flexibility when mounting the unit
horizontally, vertically, or at an angle. Download the Mounting Bracket
Accessory document from: http://www.atcsd.com/pdf/OMNIMNTB.PDF
NOTE: The bracket mounting bolts on the rear of the HSS unit require
USA 10-32 Nuts (metric M5 (5mm - 8)).
NOTE: This device is sensitive to temperature extremes, and may be permanently
damaged by temperatures that exceed those listed in the General Specifications

TERMINOLOGy/
HSS®:Acronym for HyperSonic®Sound, American Technology Corporation’s proprietary trademark
for its directional audio sound system technology.
Emitter: The silver, dimpled surface behind the front protective screen is the face surface of the HSS emitter.
This component is what emits the ultrasonic sound waves into the air.
SPL: Sound Pressure Level, a term indicating the volume (loudness) of the audio program material in the air.
Beam Width: The effective width (size) of the audio sound beam as it is projected into the air.
Direct Mode: When the listener is in the direct audio beam of sound.
Virtual Mode: When the listener is intended to hear the sound reflected from a surface.
REVIEW OF CONTROLS/
1) VOLUME UP: Pressing the Volume UP button raises the overall volume of the HSS unit
in 1.5 dB steps, from off - -45 dB – 0 dB (full on).
2) VOLUME DOWN: Pressing the Volume DOWN button lowers the overall volume of the
HSS unit in 1.5 dB steps from 0dB to -45dB. Step # 32 "mutes" the output (off).
3) ACTIVE/STANDBY SWITCH: Active/Standby is a toggle function activated by the
momentary push-button switch. Pressing the button one time will place the HSS unit into Standby
mode which will mute the audio output, pressing the button again will return the unit to active
operational mode.
4) ANALOG AUDIO INPUT: This analog, line level, audio input connector will accept
a stereo or mono 3.5mm mini-jack. (See Audio Connection section)
5) INDICATOR LED: The indicator LED indicates operational modes of the HSS unit:
• SOLID GREEN: The unit is on, functional, and active
• FLASHING GREEN: The unit is on and currently in standby mode (audio is muted)
• RED: The audio signal is clipping (distorting). Reduce the level of the incoming audio
signal or lower the HSS volume control.
6) CONTROL INTERFACE: (See Connections Section) Volume Up/Down and
Active/Standby can be controlled through this remote connection
Ventilation Requirements
You must insure that the HSS unit receives appropriate ventilation. Do not mount near curtains
or other surfaces that might cover or partially block the ventilation of the unit. If the HSS unit
is ceiling or plenum mounted, ensure that proper ventilation requirements are observed.
Be sure that insulation or other materials do not interfere with the unit ventilation.
Electrical Power Requirements
Refer to the Specifications section at the end of the manual to determine the specific amount of
AC power required for this device. This HSS unit contains highly sophisticated digital circuitry
which can be damaged by noisy AC power or extreme degrees of voltage fluctuation. Use care
to provide properly filtered and controlled AC
power to the HSS unit. Use care to provide the
same type of power you would use for a computer
or TV.
Audio Connection
AUDIO INPUT: The analog audio input connector is
a 3.5mm female STEREO (tip, ring, sleeve) mini-
jack, containing two input channels. In the normal configuration, the input jack accepts a stereo sig-
nal and sums the two channels together. (For example, the Left and Right outputs of a standard
portable CD player will be summed together at the input to the HSS unit).
With the volume control setting on the HSS unit set to FULL volume, a 0.5V p-p input signal
per channel is the threshold of clipping. You may input a signal up to 2.0V p-p into each channel
without clipping if the volume control is turned down by -12dB or more. An input signal higher
than 2.0V p-p into either channel will clip the A/D converter and turning down the volume control
will not eliminate the resulting distortion. The nominal input level is approximately 1.0V p-p per
channel. This level provides the user the ability to maintain a reasonable level control over the
incoming audio material.
NOTE: This HSS unit is equipped with a safety feature that minimizes the risk of overdriving the
unit. Should the input signal be too high, or the volume set too high and the unit senses that it
may start to clip, it will automatically temporarily reduce the volume setting to a safe level.
Once clipping is no longer occurring, the original volume setting is gradually restored. This vol-
ume restoration is intentionally slow in order to offer maximum protection and to prevent the
"pumping" that sometimes occurs with other automatic level controls. Depending on condi-
tions, this gradual recovery may take up to a minute. The unit will indicate that it is reducing
volume to prevent clipping by flashing the green LED red approximately once every 5 seconds.
ALTERNATE ANALOG AUDIO INPUT CONFIGURATIONS
Two alternate input configurations are supported without any modifications to the HSS unit:
1) A mono signal may be input into either channel leaving the other channel open or unconnected.
As in the typical stereo case, a 0.5V p-p input yields full output at the maximum volume setting.
2) A mono signal may be input into the HSS unit using a 3.5mm mono male plug. In this case the
input levels are doubled: in other words, a 1.0V p-p input is required to achieve a full output and
4.0 Vp-p is the maximum input before clipping.

OPERATING INSTRUCTIONS/
This HSS sound system is fully self-contained and requires very little in the way of
operational information.
1) Connect the HSS unit to the proper voltage AC power source.
2) Press the power switch to the ON position. (The unit will self initialize).
3) If an incoming audio signal is present, the audio may immediately be heard from the HSS unit
depending on what has been selected from the remote control or the last volume control
setting before the unit was last turned off.
4) Volume Adjustments: (NOTE: It is always best to begin with a low volume setting).
a) If your audio source has NO volume control (line output), adjust the volume of the
HSS unit using the Up/Down volume buttons (or remote control).
b) If your audio source has a volume control
1. Stop playback of the external audio source.
2. Adjust the HSS unit volume control to full On (maximum).
3. Then, reduce the HSS volume by approximately 8 steps
(8 presses of the Down Volume button)
4. Begin playing the audio source. Adjust the external volume control to the
desired level from the HSS unit. If distortion occurs before reaching the desired
volume, reduce the external volume control and increase the HSS unit volume control.
NOTE: 5 seconds following any change, the unit will maintain that change of volume setting and play/standby status,
even if the unit is turned off or disconnected from AC power. For example, if you want the unit to remember your last
setting, wait at least 5 seconds after the change before turning the unit off.

MAINTENANCE/
Cleaning
Dust: It is recommended that the HSS unit be kept free from excessive dust. A small computer
style vacuum or compressed air may be used to remove excessive dust from the surface of
the emitter and around the controls. Routinely remove dust from the rear fan cover and air
vents surrounding the unit.
Emitter Surface: DO NOT ATTEMPT to clean the surface of the emitter with any device other
than compressed air at less than 10 PSI. (Use only low PSI compressed air available in small spray
cans from all electronics stores).
Troubleshooting/
• Check to be sure that the green status LED is on.
NO AUDIO OUTPUT FROM HSS DEVICE: (real-time unit)
• Turn off AC power. Reapply power to the unit.
• Be sure the volume setting has not been turned down or off.
• Be sure that the audio input connector is properly inserted into the connector.
• Ensure that an appropriate audio signal is being fed to the input connector.
