Introduction  
Congratulations on your purchase of a Revolabs Wireless Microphone System! This system utilizes  
1.9 GHz DECT technology, and high band-width audio from multiple wireless microphones, enabling  
clear, reliable, un-tethered communications in recording, audio/video conferencing, speech  
recognition, VOIP communications, sound re-enforcement as well as many other environments  
requiring clear audio capture.  
The Revolabs HDSingle and Dual Channel Wireless Microphone Systems have high definition  
audio, 50 Hz to 20 kHz, which allows the systems to pick up the entire human voice spectrum. The  
HD Single and Dual Channel Systems are a unique marriage of innovative technology and ergonomic  
design, employing Multi-Carrier Time Division Multiple Access and Time Division Duplex  
(MC/TDMA/TDD) radio transmissions both to and from the microphone.  
This technology allows the microphones to co-exist with other wireless products such as wireless  
LANs (802.11b&g), and includes digital encryption technology to ensure secure communications.  
System Components  
Depending on which system you’ve purchased, your Revolabs HDSystem contains the following:  
Mountable Single or Dual Channel Base Station  
Single or Dual Channel Microphone Charger Base  
HD Wireless Microphones, purchased and boxed separately  
The Base Station houses the processor and one end of the wireless connection. It features one set of  
PCB diversity antennae and offers individual line-level or mic-level audio in/out for each microphone  
channel.  
This allows for external audio processing such as:  
Mixing  
- 3 -  
 
Acoustic echo cancellation (AEC)  
Feedback elimination  
Level control  
Equalization  
Noise cancellation  
The system is designed to optimize audio capture/reproduction by providing:  
Consistent audio input from all participants  
Minimum room noise  
Mute control  
Wireless encryption  
Automatic channel selection  
Full duplex audio  
The Charger Base charges the HD Wireless Microphones and stores them when not in use.  
Installing the Revolabs HD ™ Base Station  
The Revolabs HD Channel Base Station, shown below in front and rear panel views, manages  
wireless audio signal processing, pairing, and muting between the Revolabs microphones and the  
Base Station.

To Install the Base Station:  
1. Plug the power cord into an appropriate outlet  
2. Connect the necessary outputs and inputs  
Revolabs HDBase Station Audio Connections  
There are (2) 3.5mm balanced inputs and (2) 3.5mm balanced outputs on the back panel of the unit  
providing access to each channel’s audio signal.  
The three terminals correspond to:  
Tip = Positive +  
Ring = Negative –  
Sleeve = Shielded Ground  
There are one or two output channels representing a separate channel for each microphone. The  
microphone output connectors need to be attached to the input connectors of an audio mixer.  
The Base Station input connectors (also 0 dBu) may then be attached to mixer channel outputs.  
Because the system is full-duplex, the input connections provide the ability to hear program audio  
using a 2.5mm earpiece attached to the microphone (supplied with the wearable microphone).  
Depending on the application, it is possible to feed a single audio feed back to each earpiece. This  
would allow for translation, personal hearing assistance or other services to be incorporated into an  
application.  
NOTE: The USB port may exhibit static sensitivity. If the Base Station audio shuts down after  
handling, please power cycle the Base Station  
Note: The HD Single/Dual System is not compatible with any other Revolabs system and  
therefore cannot be installed in the same room. The HD and Solo Wireless Microphones and  
Charger Bases are not interchangeable. No more than one HD Single/Dual system can be used in  
a single room. Please contact support@revolabs.com for design recommendations.  
Configuring the Revolabs HDTM Base Station  
Each Revolabs HDTM Base Station must be configured properly prior to use. Accurate configuration is  
dependent on several variables such as:  
Is Line Level or Mic Level signal required?  
Refer to setting Dip Switch 3 below.  
How many HDTM Dual/Single Systems are being used together in close proximity?  
If you have more than one Revolabs Wireless Microphone System, refer to setting Dip  
Switch 7&8 below. Note: It is recommended that the lowest functioning Transmit Power  
be used for each system.  
How large is the room?  
Refer to setting Dip Switch 7&8 below. Note: It is recommended that the lowest  
functioning Transmit Power be used for each system.

DIP Switch 1- Output Mixing:  
When DIP Switch 1 is OFF(default), each HD microphone has its own 3.5mm balanced audio output  
on the Base Station. When DIP Switch 1 is switched on, the audio outputs of the two HD  
microphones are mixed together and sent to both outputs.  
DIP Switch 2 - Low Pass Filter:  
When DIP switch 2 is OFF(default) the microphone provides a 50 Hz-20 kHz audio bandwidth. When  
DIP switch 3 is ON, a LPF is activated taking the audio bandwidth to 50 Hz-15 kHz.  
DIP Switch 3 Audio Output Level:  
When DIP switch 3 is OFF(default) the microphone outputs provide a line level signal~0 dBu. When  
DIP switch 3 is ON, the microphone outputs provide a mic level signal ~-40 dBu.  
DIP Switch 4 - Mute Mode:  
When DIP switch 4 is OFF(default) each microphone has its own individual muting capabilities. When  
DIP switch 4 is ON, the microphone mute buttons are deactivated resulting in the mics always being  
active and un-muted when not in the Charger Base.

continue beeping until it turns off in about 15 minutes.  
Pairing Wireless Microphones to Base Station  
Pairing creates a link between the HD Wireless Microphone and the Base Station, with a unique  
electronic serial number. When the microphone and Base Station have been previously paired, the  
mic will automatically try to connect to the same Base Station whenever it is lifted from the Charger  
Base.  
Note: Microphones in new systems must be paired to the Base Station with each microphone  
assigned to a unique channel on the Base Station.  
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).  
A microphone that is not paired will be indicated by a cycling RED-GREEN LED pattern. A Base  
Station channel that is not paired to a microphone will not show any activity on the channel LED  
(make sure unit is first powered on by observing GREEN backlit front panel display).  
When channels are paired, both microphone and channel LEDs will flash RED as microphones are  
removed from the Charger Base and flash GREEN when un-muted. Remember that only one  
microphone can be paired to any single Base Station channel.  
- 13 -  
 
To pair an individual microphone to the Base Station:  
1. Turn the microphone OFF (no LED activity). If the microphone is ON, press and hold the Mute  
button for 10 seconds until the LED turns solid RED then release the button to turn the unit off. (do  
not release the button when you hear two beeps).  
2. Place the microphone unit into pairing mode by holding the Mute button down for seven seconds.  
The LED will turn solid RED. Release the Mute button. The microphone is now in pairing mode.  
3. Within one minute, push and hold the button for the desired channel on the Base Station for seven  
seconds until the LED turns solid red then release. The LED for that channel will be solid red until  
pairing starts, as indicated by a quick GREEN flash, then switching to flashing RED on both the  
microphone and the Base Station (muted audio). Pairing is now complete.  
Revolabs HDTM Single or Dual Charger Base  
When microphones are not in use, they should be properly inserted into the Revolabs HD Charger  
Base. It is important to ensure that all system microphones are inserted fully in the base so that  
charging will occur. Features of the base are shown in the following figure.

1. LED indicator power status indicator  
2. Charger Bays charges up to 2 Microphones  
3. Power Cord Receptacle power supply input, 9-24VDC (on rear)  
Power Module  
The Charger Base requires 5VDC power, provided by the AC Adapter. Plug the supplied AC adapter  
into an appropriate power outlet 110-240 AC, 50-60Hz. The power LED on the Charger Base will  
illuminate.  
Charging the Microphone Batteries  
First-time use Before using the wireless microphone the first time, charge the batteries in the  
microphones for eight hours (or overnight) in the Charger Base.  
Recharging When the YELLOW LED starts to flash intermittently on the microphone the battery  
has 30 minutes of charge remaining. Over time (years), batteries gradually wear down and will result  
in shorter run times. This is normal. Always return microphones to the Charger Base when not in use.  
- 14 -  
 
Important: The Lithium Polymer rechargeable batteries that power the microphones are not user  
replacement instructions and to assure the proper disposal method is used. Warning: Never  
dispose of batteries in a fire because they may explode.  
Either a solid RED LED (charging) or solid GREEN LED (100% charged) will appear to confirm that  
the microphone is inserted properly in the Charger Base. The microphones are not transmitting audio  
to the HD Base Station while in the Charger Base. In normal use, batteries should fully charge in  
about 2 hours, but will ―quick-charge‖ to 80% capacity in approximately 1 hour and 20 minutes. Fully  
charged microphones left in the Charger Base remain solid GREEN.  
Updating the Revolabs HDTM Firmware  
Revolabs HDTM Systems are field upgradable for the firmware portion of the Base Station and  
microphones. The firmware must be sent to the Base station using the Revolabs HD Single/Dual  
firmware loader. The software can be downloaded at www.revolabs.com/downloads.  
Updating the HD Single/Dual Channel Base Station and HD Microphones  
1. Connect to the Base Station using the mini-USB cable.  
2. Pair both mics to the Base Station and make sure they are out of the Charger Base.  
3. Start the Revolabs HD Firmware Loader software  
4. Choose the desired firmware version from the location it was saved during download.  
5. Choose whether you would like to update the Base Station, Mics, or Both.  
6. Select OK. The Revolabs HD Firmware Loader will notify you when complete.
