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.

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.

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.

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.

Firmware Updates

EasyTalk USB Solutions

Vaddio EasyUSB Solutions - Document Number 342-0449 Rev C Page 39 of 48

The EasyUSB Mixer/Amp and EasyMic MicPOD devices can be upgraded in the field with the use of the Vaddio

Loader software application. The processes for firmware upd ates are as follows:

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)
