Room Design & Applications
Room Considerations an d Layout:
o Room Acoustics
The room’s acoustical ch aracteri st ics play an important part on the performan ce of the audio confere nce. Two
key factors impacting speech intelligibility in conference room applications are reverberation and noise.
Reverberation refers to reflected audio signals that bounce off walls, tables, ceilings and arrive at the listener
at a later time than the direct sound from the talker (see diagram).
Diagram: Example of Reverberation Effects
Reverberation reduces the compreh ension of the speech by the list ener. Most users have ex perienced the hollow
tunnel sounding speech d uring an au dio conference. This is typically attributed to a highly refl ective room in which
hands-free audio is being conducted. Negative effects of reverberation within the meeting room can be reduced
with some simple dampin g treatments. Design options include:
Acoustical Wall Panels: Acoustical wall panels can be installed within the room to reduce the reflections off
walls.
Window Treatments: Glass is a highly reflective material for audio. Installation of blinds will reduce the
reflections significantly.
Floor Treatments: Floor treatments such as carpet or rugs will reduce the reflective properties of the room
and improve acoustical properties for conferences.
The second acoustical characteri stic that can impede spee ch quality within a conference room is the ambient noise
level. The higher the noise level within a room, the more difficult a listener will have in comprehending speech
content from the talker. Noise sources ca n include air handlers, room equipment, and lighting sy stems. The overall
noise characteristics within a room are called Noise Criteria (NC). The noise criteria are a measurement of sound
pressure level (in a space with no talkers) in relationship to frequency.
EasyTalk USB Solutions
Vaddio EasyUSB Solutions - Document Number 342-0449 Rev C Page 13 of 48
Diagram: Noise Criteria Table
Typically the noise criterion needs to be within the 30 -40 or below range for effective human perception. Th e noise
contributions to the audio being sent to the far-e nd pa rticipa nts can be exaggerated by the microphone pla cement.
The microphones are amplified and thus also amplify the ambient noise sources within the room. Care should be
taken to minimize noise contributions within the room and the relationship with the microphone positions. Things
to avoid are:
Don’t place microphones in proximity of noise so urces (Projector or PC fans)
Avoid locating microphones near high air flow path s related to HVAC Systems (heating, ventilation and
air conditioning).
EasyTalk USB Solutions
Vaddio EasyUSB Solutions - Document Number 342-0449 Rev C Page 14 of 48
Microphone Placement
The closer the microphones are to the participants within a conference, the more natural and intelligible the voice
will be to the far-end participants. For optimum audio performance, the microphone should be placed at no more
than 50% of the critical distance. A microphone’ s critical distance is the distance from the talker to the microphone
in which the direct audio signal is the same intensity as the reflected audio (see diagra m).
Diagram: Microphone Critical Distance
The EasyMic MicPODs use three unidirectional condenser elements to provide 360 degree audio pickup pattern
within the room. In general, the EasyMic MicPODs should be placed in a location that minimizes the distance to
the majority of the participants (talkers) within the roo m. The clo ser the MicPO D is to the parti cipant the better the
sound quality produced. The EasyMic MicPOD table mic pickup diagra m below can be used as a rule of thumb for
sound quality versus talker distan ce. Performance may vary depending on room acoustical condition s.

Vaddio EasyUSB Solutions - Document Number 342-0449 Rev C Page 15 of 48
Loudspeaker Placement
The location of the loudspeakers within the conference room is a critical factor for the user’s experience. The
primary factor is to ensure a comfortable audio level (Sound Pressure Level) is producing the same level at all
participants within the room. Also, a minimum distance of 4 feet separation between the EasyMic MicPOD and
loudspeaker should be maintained for optimum audio conferencing performance. In addition, speaker placement
has special criteria associated with specific applications to improve intelligibility.
Video Conferencing Application: In a videoconferencing applicat ion, human audible perception is improv ed
by the visual presence of the far-end participants. Therefore, the desire is for the audio loudspeakers to be
located near the LCD display. The combination of audio and video originating from a single position presents
a similar user experience to both the far-end and lo cal participants of physically being in the same room.
Teleconferencing Application: In audio only type conference s, the desire is to produce an evenly distrib uted
sound level to all participants. If the loudspeakers represent a point source to the participants, they will begin
directing their speech at the loudspeaker (point source). This can distract from natural conversations that are
desired in a collaborative session. The recommendation is to add additional loudspeakers in these scenarios
to negate creating a single loudspeake r point source within the room.
The EasyMic Mixer/Amp uses a 2-channel class-D amplifier suitable for driving loudspeaker loads down to four
ohms. This allows two 8 ohm loudspeakers to be paralleled out of each amplifier channel supporting a maximum
of four (4) loudspeakers.
Typical Table Installation Arrangements:
The EasyMic Mic MicPODs can be arranged in a number of topologies to accommodate the conference room
furniture configurations. The diagrams below illustrate a few common conference room layouts.

*Note the distance requirement is still 4’ between the speakers and the microphones.
Typical Ceiling Installation Arrangements:
Recommended ceiling installation arrangements for the EasyMic Ceiling MicPOD and ceiling speakers are depicted
in the above diagrams. Installation guidelines for ceiling applications include:
Maintain a minimum ceiling microphone to ceiling speaker distance separation of 4’ (1.22m) for
optimum performance.
Avoid placing ceiling microphone arrays next to HVAC systems, lighting ballasts, projectors and
any other devices that are noise generating sources. Remember that large amplitude noise
sources will be amplified by the microphones.
Avoid hanging microphone heads in direct path of HVAC blowers within the room. Excessive air
flow over the microphone elements will redu ce intelligibility of the audio.
The EasyMic Ceiling MicPOD was designed to allow the installer to adjust the hanging height of the microphone
element from the ceiling. A 36” drop cabl e is tethered to microphone array head a nd a strain relief clamp has been
incorporated into the interface module. This allows the hanging length of the ceiling array to be variable with excess
cable being secured with the strain relief clamp. For optimum performance, the microphone array should be as
close to the participants as possible. However, a minimum hanging height of 12” away from the ceiling should be
maintained.

The next diagram depicts a similar configuration but interfaces to an external audio amplifier instead of using the
internal 2 x 20 watt amp within the EasyUSB Mixer/Amp. The EasyUSB Mixer/Amp will automatically configure the
Acoustical Echo Cancellation functions within the EasyMic MicPOD to work with these loudspeaker scenarios.
For an optimum audio conference experience using an external amplifier, an end-user should
use the Volume Controls on the EasyMic for adjustments and avoid adjusting volume at the
external amplifier. Volume adjustments externally to the EasyUSB device will lead to momentary
occurrences of the dreaded half-duplex operation while in a call.

LCD Monitor Loudspeakers:
This same connection scheme using the Line Output for the connection to the room’s loudspeaker can be used if
desire is for playback to originate from LCD displays using its internal loudspeakers. In this application, the user
should avoid using LCD volume controls for adjusting level during a conference for the same reason described
above.
It is important to note that some LCD displays default the audio input source to the HDMI
connected video source.
For instance when a PC is directly connected to the LCD with an HDMI cable, some LCD displays will by default
use the PC’s soundcard for playback audio and not the EasyUSB Mixer/Amp. If this occurs the EasyMic MicPOD
Echo Cancellation will not function properly.

System Configuration and Programming
EasyUSB Mixer/Am p:
The EasyUSB Mixer/Amp has an eight pin dip switch on the rear of the device for allowing installers to customize
product for the desired conferencing application. Available configuration functions are listed in Table below. The
“up” position on the dip swit ch represents enable and the “down” position represents disable.
Table: EasyUSB Mixer/Amp Dip Switch Configuration Settings
FunctionDescription
DefaultUSBConference
Mode
This mixing mode sums the Line Input with the EasyMic audio and
sends it to the USB Transmit. The USB Receive is sent to the amplifier
output, Line Output, and AEC Reference. This will be the default mixing
operation when no switches are enabled.
1RS‐232Mode
This mode switches the RS -232 port configuration from a DCE to a
DTE device. If DIP 1 is Down (disabled), the Mixer/Amp RS-232 port is
configured as a DCE device, allowing direct connection to a DTE
device such as a PC's RS-232 port or external co ntroller device. If DIP
1 is Up (enabled), the Mixer/Amp RS-232 port will be configured as a
DTE device, allowing direct connection to a DCE device such

Mixing Modes:
The EasyUSB Mixer/Amp support s three distinct audi o mixing modes for comm on audio confe rencing application s
in which the product may be used. The mixing modes are selectable from the rear dip switches on the EasyUSB
Mixer/Amp. Each mixing mode automatically reconfi gures the internal matrix mixer for a udio signal routes required
for proper operation of the acoustical echo cancellation functions within the EasyMic devices. All mixing modes
will support PC-based audio conferencing.
USB Conferencing Mixing Mode (Default): The USB Confe rencing mixing mode is the d efault configuratio n and i s
intended for use with a PC running a Unified Communication soft-client application. In this mode, the EasyUSB
represents a USB playback & recording device to the PC.

*“X”‐representsaninternalcross‐pointwithinthematrix.*
Video Conferencing Bridge Mode (Switch 2): The VC bridge mode is intended for interfacing the EasyUSB
Mixer/Amp to a traditional videoconferencing endpoi nt that may have been previously installed within the room. In
this mode, the internal matrix mixer creates the appro priate routes required to bridge the USB audio a nd traditional
VC endpoint audio signals for prop er conferen cin g op erations. This allows both the far end (PC & VC) to hear the
local microphone audio. In addition, the local participants will hear the audio originating from the PC and VC far
end.

Advanced Audio Processing Functions
Speaker EQ Filter (Switch 4): A specialized loudspeaker equalization filter is included within the EasyUSB
Mixer/Amp and is applied to both spea ker outputs when enabled. The EQ filter is d esigned to emulate a spatial
image into the room for voice band signals based upon a mono source. The EQ filter can enhance speech
intelligibility into the room particularly when used with band-limited loudspeakers. The filter increases low end
response while empha sizing voice bands to create a bright natural sound into the room.
Compressor & ALC (Switch 5): Switch position 5 enables a dual purpose audio processing function for the
speaker outputs. It incorporates an aut omatic level control (ALC) in conjunction with a comp ressor/limiter. The
ALC will automatically add gain to low level signals to produce a constant level output to the loudspeakers. In
addition it will compress high level signals to prevent clipping the speaker outputs. The result is a constant
playback level into the room independe nt of the far-end audio source during the conference call.
Audio Delay (Switch 6): An audio delay block of 25 milliseconds can b e enabled with this switch. The audio
delay block is intended to improve lip sync issues that can be created by LCD display’s video pro cessing delay.
Some LCD displays can have internal video processing delay associated with the video input originating from
the PC used in the conference. The audio delay will add an additional 25 milliseconds before audio sample is
played out the speaker output cha nnels.
AEC Disable (S witch 7): The acoustical echo cancellation disable (Up position) will disable echo cancellation
on all EasyMic devices connected to the EasyUSB Mixer/Amp. This function is intended for tro ubleshooting or
special applications. Special applications may include local recording of room audio in non-conferencing
applications and other stuff like that too.
Interfacing with the HD-USB Camera for Control
The EasyUSB Mixer/Amp also has the ability to send presets to the ClearVIEW HD-USB
Camera. An RS-232 communication session can be established by setting dip Switch 1 to
the Enable position. This places the EasyUSB Mixer/Amp as Data Communication
Equipment (DCE) eliminating the need for a null modem cable to the ClearVIEW HD-USB
Camera. This switch also changes the baud rate to 9600 allowing direct communications
with the camera. A standard CAT-5 cable is used between the two devices. Once
connected, a camera preset is run when the user presses the One-Touch Camera Preset
button on the EasyMic MicPOD. The ca mera preset commands are dire ctly mapped to the
EasyMic ports.

A Note about Working with Unified Communications Soft Clients
As the examples with Skype and Microsoft Lync indicate, the soft clients essentially all work the same way.
However, each of them have their own way of getting to the proverbi al finish line. The language and nomenclature
is different, the file systems and drop down menus differ, but the underlying objective is to assign the EasyUSB
Mixer/Amp as the speaker and the mic for the PC to use as I/O for the soft client application.
As more examples are gathered, each of these 1-2 page TechNotes will be posted on the Vaddio website for
reference and instructional purposes.
The most important thing about interoperability with PCs and soft clients is to involve the IT
department and Network Administrators that are responsible for their company’s lifeblood (or
network). In all cases it is important to work with personnel within the IT department to ensure a
successful deployment of the EasyUSB Tools offered by Vaddio. While these products are easy
to work with, there are always a handful of “gotchas” that baffle and confound even the brightest
of amateur computer guys. Please involv e the IT pros for best results.

Step 1: If you are uncertain about updating or u pgrading the equipment, plea se contact Vaddio Techni cal Support
first. There is a possibility that any device can be turned into a brick, so give Tech Support a call first to get the
dos and don’ts of updating.
For EasyUSB Mixer/Amp: Set Dip Switch 8 on the back of the Mixer/Amp to high. Power cycle the Mixer/Amp.
Connect to the RS-232 port on the Mixer/Amp. Laun ch the Vaddio Load er appli cation on the P C and set the COM
port to the associated PC connection. Select the Mixer/Amp in the drop down list at the top of the page. Select
the load file from your local or network folders. Press the Start button on the loader. This will begin the firmware
update transfer to the unit. A progress bar will indicate when the transfer is complete. Never interrupt a transfer,
even if it looks like it isn’t doing anything. Interrupting a transfer can brick the unit.
For EasyMic MicPODs: The EasyMic MicPOD or Ceiling MicPOD is updated through the Mixer/Amp. Only one
EasyMic can be connected to the Mixer Amp during the upgrade process. The Mixer/Amp must have DIP Switch
8 in the high position for the firmware update processes. The RS-232 and COM port selection on the PC as
described above is duplicated for the EasyMic process. Select either the EasyMic (Table) or EasyMic (Ceiling)
from the drop down list at the top of the page. Browse to the desired firmware image to update the EasyMic with.
The files will end with an .ldr exten sion. Press the start button to begin the image transfer to th e device. A progress
bar will indicate status during the update process. Once complete, plug the second EasyMic MicPOD into the
Mixer/Amp and repeat.

Appendix 2: EasyUSB Mixer/Amp Serial Commands (ASCII)
The EasyUSB Mixer/Amp has an RS-232 command i nterface for configuration and real-time control. T he interface
can be used interactively with a serial terminal emulator su ch as AMX or Crestron Control systems. The DIP Switch
1 must be in disable mode for the EasyUSB Mixer/Amp to function as a Data Terminal Equipment (DTE) device.
The command echo and prompt can be enabled or disabled with the 6121 command. When enabled, command
input to the EasyUSB Mixer/Amp are echoed back, and a ‘>’ prom pt character is automatically output on a carria ge
return. When the command echo and p r ompt are disabled, the echo and prompt characters are suppressed.
For all commands, the termination character is a carriage return (hex 0D). Responses from the EasyUSB
Mixer/Amp will end with a carriage return followed by a line feed (hex 0A).
The Baud rate of the EasyUSB Mixer/Amp is 38400. (However, if in DCE mode for direct connection to Vaddio
Cameras, baud rate will be 9600). The serial format for the EasyUSB Mixer/Amp is:
Stop Bit: 1
Data: 8 bit
Parity: None
Flow: None
The EasyUSB Mixer/Amp protocol is based upon a “Set” and “Get” scheme. Set commands automatically return
an acknowledgement upon execution.
The “Get” command returns a string representing the current value of the queried setting.
“Set” commands return one of three responses:
OK (4100),
Unknown command (4199), or
Bad parameter (4198).
“Get” commands return a response string indicating the command being responded to and the data requested.
The format of a “get” response is a 4-digit response code, a space, and a two-digit hex value. Examples of
command usage are:
Set Command Usage: > 6101 00 <carriage return> (unmute the microphones)
Response: > 4100 00 (Microphone not muted)
Get Command Usage:> 5101 <carriage return> (queries current mute state)
Response: >4101 00 (Microphone not muted)
