In addition, you might have bought one or more Revolabs Elite wireless
microphones. Each microphone package will include:
Revolabs Elite wireless microphone (different styles)
Lanyard and over-the-ear speaker element (wearable microphone only)
Batteries
Documentation
The Executive Elite Base DSP unit contains all the logic required to support the
audio signal from the microphones in the different output formats (analog
audio, digital audio over USB, digital audio over AVB). It supports the
management interfaces (front panel, local web UI, room control system UI), as
well as communication with the remote cloud based UI.
The Remote Antenna receiver contains all components required to receive (and
send) audio signals from (and to) the microphones. It includes the required
diversity antennas. The remote antenna also controls over the air
synchronization between systems, and provides the scan of the RF frequency to
determine how many (additional) microphones might be used in the area. The
remote antenna receiver communicates with the Elite Base DSP unit using a
direct IP connection (Cat 5e or Cat 6 cable).
The Charger Base stores and charges the wireless Elite microphones when not
in use. Communication capabilities are not required for the charger tray
because all information transferred between microphones and the Elite base
DSP unit passes over the wireless connection. This includes pairing of
microphones to receivers, firmware updates of microphones, and commands
sent to the microphones.
15
Revolabs Elite wireless microphone systems are designed to work with other
audio equipment typically found in an installation. This equipment is typically
used for:
Audio Mixing
Acoustic echo cancellation (AEC)
Feedback elimination
Level control
Equalization
Noise cancellation
The Revolabs Elite system provides some of these features as well. It is
recommended to use either external or Revolabs audio control systems to
change settings and adapt the audio to your exact needs. Best audio quality is
easier to attain when only one system is used to adapt the audio.
The Revolabs Elite system is designed to optimize audio capture/reproduction
by providing:
Consistent audio input from all participants
Minimize room noise
Mute control
Wireless encryption
Automatic channel selection
Full duplex audio.

Remote Antenna Receiver
Routing channels
The Remote Antenna Receiver consists of two pieces – the mounting plate and
the Antenna housing. The Remote Antenna Receiver is installed similar to a
wireless access point. Best locations are high on the wall, facing into the room
in which the microphones are located. Each Remote Antenna Receiver
supports one Base DSP Unit. If more than one Base DSP Unit is installed for a
room, e.g. more than eight microphones are required, several Remote Antenna
Receivers will be installed in this room. It is best to install the receivers on the
same wall facing into the room, spaced at least 12 inches (30 cm).
The Remote Antenna Receiver contains several antennas to provide the best
transmission and reception of the radio signal to and from the microphones.
20
The back-plate of the Remote Antenna Receiver provides means to install the

antenna in different environments. See the below diagram on how to install in
the different environments.
Independent on which way the wall plate is attached, do not over-tight the
screws.
When installed on the wall or on an electrical one gang or two gang box the
network cable can be routed through the Network cable opening. Alternatively,
the network cable can be routed to leave the Remote Antenna Receiver either
on the top or the bottom, using the provided routing channels.
Once the back plate is attached to the wall and the network wire is connected
to the Remote Antenna Receiver and routed correctly, the Remote Antenna
enclosure is attached to the back plate by slipping it from the top onto the two
hooks, and then pressing the bottom back against the wall plate until the snap
clicks in.
To separate the Remote Antenna Receiver housing from the wall plate insert a
screwdriver from the bottom into the slit and press against the snap while
carefully pulling the Antenna Receiver forward until the Antenna Receiver
releases from the snap. The Remote Antenna Receiver housing can now be
detached from the wall plate.
21
Connect Remote Antenna Receiver to Base DSP Unit
5 in
13 cm
1/4 – 3/8 in
7 – 10 mm
Connect the Remote Antenna Receiver with the Antenna output of the Base
DSP Unit using a CAT 5e or Cat 6 cable.
NOTE: This needs to be a, point to point connection between the two
units. This is a time crucial connection. Routing this connection
through a switch will fail.
The Antenna output of the Base DSP unit provides Power over Ethernet which
is required to power the Remote Antenna.
Before connecting the network cable, ferrite beads need to be installed on
either end of the cable to minimize electro-magnetic interference. One ferrite
bead should be attached ¼-⅜ of an inch (7 – 10 millimeters) from the end of
the cable that will connect to the Base DSP unit. The second ferrite bead needs
to be attached 5 inches (13 centimeters) from the end of the cable that will
attach to the antenna.
NOTE: The Antenna Receiver provides room for the ferrite to be placed in
the antenna casing, underneath the mount plate. If running the
cable through the Network Cable Opening in the mount plate the
ferrite must be installed after the cable has been pulled through.
Otherwise it will not fit through the opening.
22
System set-up
Once the Remote Antenna Receiver has been connected to the Base DSP unit,
connect that unit to the power mains and turn the switch on the front of the
unit to “1” from “0”. The unit will now power up. You will see messages on the
front screen providing information until the unit is operational. Once the
Screen with the VU screen is shown, and the Antenna symbol is constant, the
system is operational.
For additional system configuration instructions, see later sections describing
the different user interfaces in this manual.
Revolabs Executive Elite Audio Connections
The Executive Elite Base DSP unit offers three different ways to deliver the
audio from the microphones to post-processing equipment as well as to provide
back channel audio to the microphones.
While all three audio output paths will be active at all times, only one of the
back-channel audio paths can be active. The user interfaces allow selecting
which path should deliver the audio back to the microphones.
Analog Audio
The back panel of the Executive Elite DSP eight channel base unit provides
eight 3.5mm Euroblock inputs and eight 3.5mm Euroblock outputs (the four
channel unit provides four input and four output connectors), providing access
to each channel’s audio signal.
The Euroblock connectors included in the package are designed for easy
wiring. The three terminals (from left to right) correspond to positive +, negative
-, and shielded ground G.
To connect audio In/Out on the Base Station:
1. Use the screws on top of the connector to first open the
terminals.
2. Insert an appropriate 3-conductor cable (2 conductors and
shield) into the terminals.
3. Tighten the screw to secure the cable.
4. Push the connector onto the pins centered under the desired input or
output port on the back of the Base DSP unit until firmly secured.
The microphone output connectors need to be attached to the line-level (0dBu)
input connectors of the post-processing audio equipment (mixer, DSP).
If the analog audio in is used for the back-channel audio, the Base DSP Unit
input connectors (also 0dBu) may then be attached to the output channels of
the post-processing equipment.
23
AVB Audio
1
Beside the analog audio, Executive Elite also supports digital audio input and
output. The AVB connection on the back of the Base DSP unit can be
connected to an AVB enabled network and delivers streams of output audio
data for each microphone, as well as can consume streams of input audio data
for each microphone. For information on how to set up an AVB network and
define AVB talkers and listeners see your AVB network management software.
USB Audio1
Finally, the USB connector on the back of the Executive Elite Base DSP unit
provides independent audio streams, and can consume independent audio
streams for each of its microphones. Audio is not mixed in the Executive Elite
Base DSP unit; the USB connector delivers independent streams for each
microphone.
NOTE: It might be required to install additional driver software on the
connected computer enabling the separate audio channels to be
received on the device. Please see the documentation of your
computer for more details.
Synchronizing Executive Elite units
If more than one Revolabs Executive Elite Base DSP unit is used in an area,
the units should be synchronized to ensure best usage of the radio frequency
space, and best system performance. The Executive Elite system provides
three means to synchronize systems, the Sync Bus, the AVB network, and Over
the Air synchronization.
Microphone Density and Radio Frequency Interference
Synchronizing Executive Elite systems is important to maximize the density of
microphones that can be supported in one area. Non-synchronized systems in
the same space block a higher number of radio frequency channels than the
number of microphones they support, causing RF loss and audio drop-outs. It
is therefore important to synchronize all Executive Elite systems that are in
proximity with each other to limit the number of potential audio issues. There
is no disadvantage in synchronizing systems that are not in close proximity.
Synchronization only affects the internal clocks of systems, not the channel
selection they make for their microphones. It is therefore better to error on the
safe side and synchronize even systems not expected to be in direct proximity.
Maximum Density of microphones in one area is affected by the selected audio
quality and whether back-channel audio to the microphones is enabled or not.
It is also dependent on other wireless radio frequency traffic in the vicinity, and
whether that traffic is synchronized or not. Selecting the right RF power
The USB audio connection is enabled starting with Executive Elite software version 1.2.
24
setting is important to limit the area in which RF traffic of a microphone and
receiver is being seen to the coverage area, therefore reducing interference with
adjacent areas. See later user interface sections for information on how to set
these parameters.
Selecting Synchronization Method
Choosing a Synchronization method may be done through either the Web UI, or
the Front Panel LCD.
From the Front Panel the synchronization mode may be selected from the
System Clock submenu, under System Settings. Once the mode is selected,
the interface will automatically prompt the user with a choice of Internal or
External clock mode. Only one Internal can be set for any sync mode; this
device will be the clock source to all synchronized systems. All other devices
need to be set as External, and use the clock signal of the Internal.
Through the Web UI, synchronization mode can be set on the System
Configuration page. In the table on the bottom left of that page are two
dropdown menus. The first is for the synchronization mode, and the second
for setting the system as Internal (Primary on the Executive HD) or External
(Secondary Mode on HD) clock mode.
Synchronization Bus
The synchronization bus allows connecting several Executive Elite Base DSP
units together to manage the clock between the systems.
The Synchronization bus also allows synchronizing Executive Elite Base DSP
units with Executive HD™ receivers in the same vicinity. While the
synchronization bus in Executive HD installations also managed group mute
control, this capability is handled differently in Executive Elite. When installed
together with Executive HD systems the bus will therefore only provide
synchronization data, not mute data between Executive Elite and Executive HD
systems. However, mute groups managed between Executive HD systems can
still be managed using the bus.
The synchronization bus cable is connected to the grey Euroblock BUS
connector on the Executive Elite Base DSP unit using a standard 3.5mm
Euroblock connector. The wire used should be 26AWG or better, shielded
cable. The distance between the furthest External and the Internal must not
exceed 300’ (90 meters).
25
The terminals of the BUS connector should be wired in parallel via either a
2
daisy chain connection or terminal block split. The three contacts of the
Euroblock connectors are as follows from left to right.
S. Sync
¯¯. Not used in Executive Elite (Master Mute in Executive HD)
G. Ground
If the synchronization bus is used to synchronize Executive Elite
systems with Executive HD systems, one of the Executive HD systems needs to
be set as the Internal, making that system the clock master. All Executive Elite
Base DSP units will have to be set to use the external clock.
AVB Synchronization
If all Executive Elite Base DSP units are connected to the same AVB network,
the AVB network can be used to synchronize the systems with each other.
This simplifies installation of Executive Elite systems as no additional
synchronization bus is required. However, it does not allow synchronization in
a mixed environment with both Executive HD and Executive Elite systems as
Executive HD Systems do not support AVB.
The Setup for ABV sync is through an AVB capable switch. Once the Executive
Elite synchronization mode is set in the Web UI or Front Panel to AVB, select
Auto as the Clock Mode. Through the AVB networking software set up a
network of elite systems, where at least one system is a “Talker” and the other
systems are “Listeners” to that system. The architecture also allows for
communication chains, where one Elite is set up as a Listener to a system in
the chain, and as Talker to systems further down in the chain.
OTA Synchronization2
Executive Elite systems have the ability to synchronize with other Executive
Elite systems in radio frequency range using over the air (OTA)
synchronization. This synchronization method does not require any wiring
between Executive Elite Base DSP units. In OTA mode, systems exchange
synchronization information using radio signals, therefore allowing systems in
vicinity to auto synchronize. To enable OTA synchronization, select OTA as the
Clock Source.
OTA Synchronization will be available starting with Executive Elite Software version 1.2

Front panel user interface
The Front panel user interface is one of four interfaces available to manage an
Executive Elite system. The others are the local web UI, the Cloud Server Web
UI, and the CLI (room control) interface and are described later in this
document.
The front panel contains four areas:
1. On/off switch
2. 4 / 8 LEDs (depending on the version of the Executive Elite base DSP
unit)
3. Graphics LCD display
4. 5 button navigation keypad.
The on / off switch powers the Executive Elite base and the connected remote
antenna receiver on and off. During operation, this switch should be in the
“1”, or ‘on’, position.
The LEDs on the front panel show the current microphone states. An LED that
is off indicates that there is either no microphone paired to this channel, or the
paired microphone is in the charger, out of reach, or switched off. A green
blinking LED indicates an active microphone that is unmuted. A red blinking
LED, showing a double blink, indicates an active microphone that is muted. A
rapidly red blinking LED with a single blink indicates the microphone is
upgrading. A constant red LED indicates a channel on which microphone
pairing is taking place at the moment.
The LCD screen together with the navigation keypad allows easy monitoring of
the Executive Elite system as well as managing some system settings without
additional equipment. Its home screens provide information on audio levels,
radio signal strength, and access to gain settings for the analog audio output.
The menu structure displays system information, and allows changes to some
system and audio settings. The front panel can also be used to pair and unpair microphones. It does not replace the local web UI interface or the cloud
based management interface to manage all options and functionality of an
Executive Elite system. The front panel interface will also not allow access to
password protected areas of the interface unless the system has first been set
up using the local web UI.

Home Screens
When starting an Executive Elite system, the first page that comes up on the
Front Panel LCD is the Volume Unit (VU) screen. This screen is one of the 3
home screens on the Front Panel UI. Using the “up” and “down” keys to the
right of the LCD while on the VU page will show the other two home screens.
The VU screen shows the audio volume for each unmuted, linked microphone,
as well as battery charge information.
“Up” from the VU screen, the RF View home screen shows the radio signal
strength as measured on the receiver for each microphone.
“Down” from the VU screen, the Gain control screen shows the VU meters as
well as the input gain setting for each microphone channel, which the user can
change from this screen. To adjust the gain, a user presses the “Enter” while
on the gain screen, and a black highlighted selection will appear. The channel
is selected using the “left” and “right” keys and once in the correct channel, the
up and down keys change the gain in 1 dB steps. The gain setting for the
highlighted channel is listed on the right-hand side of the LCD. The user
cannot leave the gain control screen while in channel selection mode. To leave
the screen, press “Enter” again to get into the normal mode. “Up” and “Down”
will now switch between home screens again, and using the “Right” arrow key
will enter the main menu.
28
When changing the gain or entering any menu in the front control panel that
allows the user to changing values, a password prompt will appear before the
user is allowed to proceed. To enter the password, use the right and left arrow
keys to select a digit, and the up button to change the number of that digit (0-
9). Hitting Enter will submit the password, and down brings the cursor to the
cancel button. On the front panel, the password will be valid for 20 minutes,
unless the user explicitly logs out in the Admin Settings submenu as described
further below. The factory preset password is 7386, and can be changed either
through the Admin Settings menu on the front panel interface, or the System
Configuration menu on the local Web UI.
29
All three home screens are split into 3 sections, and each section shows a
different type of information. On the far right-hand side of the screen, the
Home screen name is displayed at the top of the external systems information
box. Underneath it there can be up to 4 icons, showing if certain external
systems are connected.
- Antenna. The only icon guaranteed to be in this box. If it is blinking, an
antenna is not communicating with the Base DSP unit. If it is solid,
communication is passing between the Antenna and Base.
- Wired Sync. If a wired sync buss is being used to sync clocks between
Executive systems, the synced Elites will show this icon. Remember that sync
mode must be set before the base will look for an external clock.
- USB. When the front panel USB is in use, this icon will show
communication is being received through that port.
- AVB. When AVB is plugged into the Base, the “AVB” icon will appear.
Until the Base is set up as a “talker” or “listener”, the arrows above or below
“AVB” will not appear. To check if the Base is set up for either, remember “T”
is for talker and “L” is for listener.
Separated from the external systems box by a vertical line is the channel
information section of the Front Panel UI. At the top, each channel is labeled,
and two rows underneath provide different information depending on which
home screen is currently selected.
On all screens, the top row will show microphone status beyond linked with the
following icons:
- Microphone Lost Link, or Unknown Status Microphone
- Firmware Update in Process
- Stand-by Mode
Microphone channels that have no microphone paired, a charging microphone,
or when the microphone is switched off, will show no information.
30
Additional information from this row can be found in the following forms:
3
- Mute Symbol. Will show on the VU screen for a linked, muted
microphone.
- VU or Gain Meters. VU screen shows a VU meter for a linked, unmuted
microphone, while the Gain screen meters look the same, but do not change
unless set, and appear for all linked microphones.
- RF Meters. The RF screen will display the strength of the transmission
from any linked microphone as it is received by the base. Microphones
experiencing interference or far away will have a lower RF.
The second row displays battery information when seen on the VU and RF
screens, using the following icons:
- For a linked microphone, the battery level icon will show the charge level
by the amount of black in the battery.
- While in the charger, the battery symbol also shows a charging symbol
overlaid over the battery-charge icon3.
- A microphone using a permanent cross-over adapter will be shown with
a power connector battery symbol. A permanent cross-over adapter is one
where the microphone does not use batteries.
- A battery symbol with a +/- indicates a non-rechargeable battery or
wrong battery type. Such a battery will not charge when placed in the charger
tray.
- The type of a battery is only determined when the microphone is placed
in a charger after inserting a new battery. Up until this time the battery
symbol will show a battery with a question mark in it, indicating that the
battery type is unknown.
- Low battery, under 10% remaining.
- Very low battery, under 5% remaining.
On the gain screen, this row will not show battery information, instead having
a row of digital gain “knobs” that will match the gain shown in the meters
above them.
- Gain knob
It might take a few minutes for the charge symbol to appear after a microphone was placed in
the charger.
