Components
Your Revolabs Elite Wired Microphone comes with a 15’ (4.5 m) cable attached
to connect it to a phantom powered microphone input of a digital signal
processor (DSP), or other audio devices. The packaging includes the
microphone with cable and a short installation documentation.
The Revolabs Elite system is designed to optimize audio capture by providing
consistent and high-level audio input from all participants.
You might have purchased additional components like the installation kit to
install your microphones permanently. Please review the documentation of
these components for their installation information.

Installation
The Elite Wired Microphones with Mute Control and Indicator are equipped
with a 15’ (4.5 meter) cable that allows integration with audio equipment. If
the microphone mute is controlled locally, only the audio wires (mic positive
(red), mic negative (black), and ground) need to be conneted to the audio
equipment.
If external mute control is being implemented, and the LED indicator on the
microphone is controlled externally, the switch out (green), LED in (blue) and
I/O ground cables also need to be connected to the GPIO ports controlling the
behavior.
Dip switch Settings
The DIP switches manage the behavior of the mute
control (mute button) and the LED indicator light on
the microphone. The switches are located on the
bottom of the microphone and numbered 1 thorugh
6.
To access the DIP switches, remove the bottom door of
the microphone using a screwdriver or similar tool to
press on the latch and then remove the door. Set the
DIP switches based on the following tables to achieve
the intended behavior.

When external Control is desired, DIP switch One needs to be in the ON
position.

DIP switches 3 – 6 should be in the OFF position. If any of these DIP switch is
set to ON, local control of the mute functionality will be enabled, causing
unwanted and unpredictable microphone mute behavior and might lead to
audio distortions.
Local Mute Control
To enable local mute control (and disable the Switch Out wire and LED In
wire), DIP switch One needs to be in the OFF position.
DIP switch 2 should be in the ON position – the LED will show green when the
microphone is unmuted, red when it is muted. If DIP switch 2 is in the OFF
position, the LED behavior will be oposit (green when muted, red when
unmuted).
Only one of the DIP switches 3 through 6 should be in the ON position, the
others should be in the OFF position, depending on the mute behavior desired.

If more than one of the DIP switches 3 – 6 is in the ON position, unwanted and
unpredictable microphone mute behavior will be observed and audio
distortions will be experienced.
In Push to Mute mode, the microphone send audio data, unless the button is
pressed, at which time the microphone will mute.
In Push to Talk mode, the microphone is muted, unless the user presses the
button, at which time the microphone sends audio data until the button is
released again.
In Toggle mode, the microphone is muted or unmuted, changing its state each
time the button is pressed.

Audio wire connection
Connect the red wire to the positive (+) microphone input of the DSP or audio
equipment you use with the microphone. Similarly, connect the black wire
with the negative (-) input of the DSP. When connecting to a male XLR
connector, use the following polarity:
1 – Ground / Shield
2 – Positive (+)
3 – Negative (-)

12
Note: The Elite Wired Microphone includes some active electronic
circuitry, and therefore requires Phantom Power to be provided
from the device the microphone is connected to. The Elite Wired
Microphone requires a phantom voltage between 12 and 48V DC,
with a draw of maximum 2mA.
Control Wire Connection
The Control wires will be connected with the GPIO ports of the DSP or other
technology that is controlling the mute status of the microphones. The control
wires are only used when external control is selected using the DIP switches.
Using external control, pressing the button on the microphone will pull the
switch out line to ground. The DSP (or other technology) needs to be
programmed to react to falling edge (e.g. mute toggle), or for the switch out line
to be “low” (e.g. push to talk).
The LED In line should be connected to a GPIO out port. The Elite wired
microphones provide red and green LEDs to differentiate the state of the
microphones. The LED color is controlled by the DIP switch setting and the
voltage provided on this line. See the table on the DIP switch settings for more
details.
Microphones
Revolabs Elite Wired Microphones come in four different versions:
•Revolabs Elite Omni-directional Tabletop Wired Boundary Microphone
•Revolabs Elite Uni-directional Tabletop Wired Boundary Microphone
•Revolabs Elite 6 in (15 cm) Gooseneck Tabletop Wired Microphone

The Elite Omni-Directional Wired Tabletop Boundary
Microphones
The Elite Omni-directional Wired Tabletop Boundary Microphones enable
multiple conference attendees to use a single microphone.

1. Bottom door latch — open the bottom to change the DIP switch settings. Or
replace the bottom cover for permanent installations using this latch.
2. Audio wire — connect the microphone to the DSP or other audio equipment
using this wire.
3. Button – Local mute control, or pulling the external control line to ground
when pressed.
To use the Elite Omni-Directional Tabletop Microphone, it should be centered
on the table within 2 to 6 feet (0.6 to 2m) from people speaking and do not need
to be pointing any particular direction as they pick up sound from all
directions.
It is always better to place a microphone as close to meeting participants as
possible, while avoiding placing the microphone where it might be blocked by
equipment or paperwork. Do not place microphones too close to an audio or
video conference speaker to avoid echoes. Make sure that the microphone’s
rubber feet are sitting atop a flat surface.

The Elite Directional Wired Tabletop Boundary
Microphones
The Elite Directional Wired Tabletop Boundary Microphone, shown below, is
designed to provide optimum coverage when placed on a conference room table
in front of one to three people.
1. Bottom door latch — replace the bottom cover for permanent installations
using this latch.
2. Audio wire — connect the microphone to the DSP or other audio equipment
using this wire.
3. Button – Local mute control, or pulling the external control line to ground
when pressed.
To use the Elite Directional Tabletop Microphone, it should be placed on the
table with the metal screen facing toward the users, trying to keep the
microphone 2 to 6 feet (0.6 to 2m) from the target people. The pick-up pattern
for this directional microphone is approximately +/- 65º to either side of
directly in front of the microphone.

The Elite Gooseneck Tabletop Microphones
The Elite Gooseneck Tabletop Microphones, 6 inch and 12 inch (15 cm and 30
cm, respectively), shown below, are designed to provide optimum coverage
when placed on a conference room table in front of one person.
1. Button – Local mute control, or pulling the external control line to ground
when pressed.
2. Audio wire — connect the microphone to the DSP or other audio equipment
using this wire.
To use either of the Elite Gooseneck Tabletop Microphones it should be located on
the table with the microphone pointing toward the user, trying to keep the microphone 18
to 24 inches (45 to 60 cm) from the speaker. The pick-up pattern for this directional
microphone is cardioid, focusing a “beam” towards the speaker.
It is always better for the microphone to be as close to the person speaking as
possible, but avoid placing the microphone where it might be blocked by
equipment or paperwork. Avoid placing microphones too close to an audio or
video conference speaker to avoid echoes. Make sure that the microphone is
always placed standing on its rubber feet atop a flat surface.
