Introduction
Congratulations on the purchase of a Revolabs digital wireless communication system! We are
pleased that you have chosen the Solo Executive Wireless Microphone System with 1.9 GHz
DECT technology. The Solo Executive provides high band-width audio from multiple wireless
microphones enabling reliable, un-tethered communications in audio and video conferences.
The Solo Executive Wireless Microphone System is a unique marriage of innovative technology
and ergonomic stylish design. This product enhances audio communication in many enterprise
and professional applications. The system uses Time Division Multiple Access (TDMA) spread
spectrum technology. This technology allows the microphones to co-exist with other wireless
products such as wireless LANs (802.11B&G), as well as allowing digital encryption technology to
ensure secure communications.
System Components
Your Solo Executive System package contains a rackmountable Base Station, a Charger Base
and eight wireless microphones. The Base Station houses the processor and one end of the
wireless connection. It has two sets of diversity antennas and provides individual line-level audio
in and out for each microphone channel. This allows for additional post processing by external
multi-channel equipment. The Charger Base unit stores and charges the wireless microphones
when not in use. There are many features that this system provides that increase the productivity
of a conference call including consistent audio input from all participants, decreased room noise,
auto and manual mute, wireless encryption, re-synchronization and full duplex audio.

Solo Executive Charger Base
The Charger Base is used for storage and charging the microphone when not in use.
Microphones must be properly inserted into the base and seated flush for charging to occur.
1. System MUTE Switch — overrides individual Microphone
mute function.
2. LED indicator — power / mute status indicator.
3. Charger Bays — charges up to 8 Microphones.
4. Line Cord Receptacle — power supply input (on rear).
Power Module
The Charger Base requires 5VDC power. Plug the supplied AC adapter into an appropriate power
outlet 110-220 AC, 50-60Hz. The power LED on the Charger Base will illuminate.
System Mute Switch
There is a system MUTE button on the Charger Base. In normal operation the LED will be solid
GREEN (power on). In this mode, the microphone devices can individually mute themselves.
Pressing the system MUTE button will mute “all” wireless microphones in the system and the
Charger Base LED will turn RED. All microphones active in the system will also change to
flashing RED LED status indicating muted microphone audio. To un-mute all microphones, press
the system MUTE button again. The Charger Base LED will return to solid GREEN, and all
microphones will return to their previous state prior to the system mute.
Note: Pressing the MUTE button on a microphone while the system mute is active (solid RED
LED on Charger Base) will NOT un-mute the microphone.
Solo Personal Microphone Modules
The wireless personal microphone modules are synchronized to the rackmounted Base Station
and can be worn on the user’s shirt pocket, lapel or on a lanyard. They provide high quality full
duplex audio between each user and the conferencing phone/system. This system allows
attendees to step out of the conference room area and still participate in the call.
1. Mute Button — controls multiple microphone functions.
2. Charging Port — accepts the storage base battery charger.
3. LED Indicator — provides a visual status about wireless
module.
4. Earpiece Jack — accepts the 2.5mm plug for the earpiece.
5. Pocket Clip — attaches microphone to user.

Charging the Batteries
How to Charge
1. Place microphone(s) into the Executive Charger Base.
2. During charging, the LED indicator turns on (RED) and remains on until charging completes.
The microphones cannot be used while charging. The battery fully charges in approximately
two hours, and can be “quick-charged” to approximately 80% capacity in 45 minutes.
3. When charging completes, the LED turns off and microphone is ready for use.
Note: A fully charged module battery provides approximately 8 hours of talk time.
When to Charge
First-time use — before you can use the wireless microphones, charge the self-contained battery
for two hours in the Charger Base.
Recharging—when the orange light starts to flash on the microphone the battery needs
recharging. Over time (years), batteries gradually wear down and require longer charging times.
This is normal.
The Lithium Polymer rechargeable batteries that power the microphones are not user
serviceable. Please contact your AV service provider for replacement instructions and to assure
the proper disposal method is used.
Warning: Never dispose of batteries in a fire because they may explode.
Using the Microphone
1. Remove the microphone from the Charger Base. The microphones turn on and mute
themselves automatically when removed from Charger Base, to reduce noise while being
attached to clothing.
2. The wireless microphone has a clip on the back which allows
the microphone to be easily clipped onto a shirt pocket,
blouse or lapel. The microphone can also be clipped on to a
lanyard and be worn around the neck. Attach the microphone
to clothing or to a lanyard, as close to the mouth as possible
(within 6 - 12 inches is recommended).
3. With the microphone in the wearing position, un-mute the
microphone by pressing and releasing the MUTE button
(confirm by viewing flashing GREEN LED).
4. To turn off microphones, return the microphone unit to the
Charger Base or press and hold the MUTE button for ~10
seconds until the LED turns solid RED and turns off.
5. If the microphones are moved out of range of the Base Station (~30 meters) the connection will
be dropped (LED flashes all colors) and the microphone will mute. When the microphone is
moved back into range the connection will automatically be re-established to its original state.

Adjusting the Volume
The volume of the microphone is set at the factory and cannot be adjusted on the wireless
microphone. Access to each channel is provided on the Base Station for external amplification.
Note: Moving the wireless microphone closer to the mouth will
increase the volume.
To change the volume on the earpiece, use the dial on the earpiece
wire. Turning the dial towards the earpiece will increase the volume,
and turning the dial towards the microphone will decrease the volume.
Use the attached clothing clip to secure the earpiece wire.

Installation
The Executive Base Station is easily installed into a standard 19” AV rack system using the
supplied rack ears and standard rack screws. The equipment requires 110-220V AC, 50-60 Hz,
power. Plug the power cord into an appropriate outlet and turn the circuit breaker-protected power
switch on the back panel to Reset. The GREEN power LED on the front panel will illuminate.
Attach the four diversity antennas (two on each side) and the system mute antenna (SMA male
connector) in the center.
Connections
There are eight mini-phoenix input and output ports on the back panel of the unit providing
access to each channel’s audio signal. The provided mini-phoenix connectors are designed for
easy wiring. The three terminals (from left to right) correspond to positive +, negative −−−−, and
ground. Use the screws on top of the connector to first loosen the terminal to insert an
appropriate 3 conductor cable (3 separate conductors, or 2 conductors and shield), and then
tighten the screw to secure. Push the connector onto the pins centered under the desired input or
output port until firmly secured.
There are eight output channels representing a separate channel for each microphone. Likewise,
there are eight input channels to the unit. The microphone output connectors need to be attached
to the line-level input connectors of an audio mixer. The Base Station input connectors should
then be attached to mixer channel outputs. Because the system is full-duplex, the input
connections provide the ability to hear program audio using the provided earpiece attached to the
microphone. Depending on the application, it is possible to feed a single mixed channel back to
all earpieces or, alternatively, each user can receive a separate and unique channel. This would
allow for translation or other services to be incorporated into an application.
Set-up
The Base Station has eight indicator LEDs (one for each channel) and pairing push buttons on
the front panel. When the LED is flashing green or red then that channel is active and connected
to a wireless microphone (GREEN is for live audio, RED is for muted). When the LED is off, the
channel is inactive (the microphone is out of range or turned off).
The front panel also has two sets of diversity antennae for best reception, and a fifth antenna for
system mute reception. These antennae are removable for relocation by installation
professionals, based on the installation environment and coverage optimization requirements.
Pairing Wireless Microphones to Base Station
“Pairing” creates a link between the wireless microphone and the Base Station with a unique
electronic serial number. When the microphone and Base Station have been previously paired,
the microphone will automatically try to connect to the Base Station whenever it is lifted from the
Charger Base.
Remember, microphones are always muted (flashing Red LED) when they are removed
from the Charger Base and the MUTE button needs to be pressed to make it “live” (flashing
Green LED).
6666
Microphones in new systems come paired to the Base Station with each microphone assigned to
a unique channel on the base unit. However, if a replacement microphone is ever required, it will
need to be manually “paired.”
If a microphone is lifted from the Charger Base and the LEDs continuously flash alternating Red,
Green and Yellow, and the Base Station LEDs flash alternating Red and Green, the microphone
needs to be paired to the system. Make sure that all other microphones are properly paired, and
that the Base Station is powered on, before proceeding to pair an individual microphone. By
noting which microphone channels are already in use (paired), it will be obvious which channel to
use for pairing the microphone.
Microphone Pairing Instructions
1. First make sure the microphone is turned OFF (no LED activity). If the unit is ON, press and
hold the MUTE button for 10 seconds until the LED turns solid RED (do not release when you
hear two beeps), to turn the unit off, if needed.
2. Next, place the microphone unit into pairing mode by holding the MUTE button down for six
seconds. The LED will turn solid GREEN and then solid RED. Release the MUTE button. The
microphone unit is now in pairing mode.
3. Within one minute, push and hold the button for the desired channel on the Base Station for
six seconds to enter into pairing mode. The LED for that channel will be solid RED until pairing
starts, as indicated by a quick GREEN flash switching to flashing RED on both the microphone
and the Base Station.
Pairing Charger Base to Base Station
“Pairing” is also used to create a link between the Charger Base MUTE control and the Base
Station. When the Charger Base and Base Station are paired, the system mute function may be
used.
The Charger Base in new systems come paired to the Base Station. However, if a replacement
Charger Base is ever required, it will need to be manually “paired.”
System Mute Button Pairing Instructions
1. First, power-on the Charger Base and Base Station (power LEDs on both units are GREEN).
2. Next, place the Base Station system into pairing mode by briefly pressing the LEARN button on
the rear connection panel. The pairing LED next to the LEARN button will illuminate.
3. Now press the MUTE button on the Charger Base once. The pairing LED on the back of the
Base Station panel will go off and the power LED on the Charger Base will turn solid RED.
4. Press the MUTE button the Charger Base again. The pairing LED on the Base Station will flash
twice and the power LED on the Charger Base will turn solid GREEN.
5. Once the pairing LED on the Base Station stops flashing the MUTE button on the Charger Base
will mute all the microphones in the system.

Using Multiple Systems
If more than one Base Station is used in a room, each unit needs to be interconnected with a
sync cable using the supplied mini-phoenix connectors. The three terminals correspond to
positive +, negative −−−−, and ground. Use the screws on top of the connector to first loosen the
terminal to insert an appropriate three conductor cable (3 conductors, or 2 conductors and
shield), and then tighten the screw to secure. Push the connector onto the pins labeled BUS. One
box needs to be set as the LOCAL unit by sliding the switch next to the port to the left. The other
units need to be set to the REMOTE setting by sliding their switch to the right. The LOCAL unit
manages the entire system and allocates microphones across the available channels to maintain
frequency integrity. Note: The switch must be in the Local position for a single Base Station
system. Microphones will not function if the switch is in the Remote position.
System Mute Function Switch
In certain circumstances it is preferable to use the muting capabilities in a DSP based automated
microphone mixer instead of the Charger Base system mute. This is the case when the mixer is
providing acoustic echo cancellation and needs a continuous signal to maintain a near-end audio
reference. The two position System Mute switch located on the back panel controls how the Base
Station handles the audio output levels for muted channels.
Position 1 (left side - default): Base Station completely shuts off audio out of each channel that is
in the mute state.
Position 2 (right side): Base Station leaves audio output of muted channel at the same level and
signals the appropriate “mute out” pin on DB25 connector for line muting on external hardware.
Note: The System Mute button on the Charger Base does not mute the system when the switch
is in Position 2 (right side).
DB25 Control Port
In connection with the System Mute switch, the DB25 Control Port allows the use of third party
control systems using parallel port IO (active low, open collector). The pin-out status functions
shown below can be used to provide system muting operations via third party products. The
System Mute switch should be pushed all the way to the right for this feature to operate. Please
see the operating manual for the control device for more information. The MUTE_OUT indicators
are used to determine muted channels, and the SYS_MUTE mutes all channels.
