Using the Revolabs Dual Wireless Microphone System

The Revolabs Dual Wireless Microphone System comes with two (2) microphones.  There are a Revolabs HD Wearable microphone and a Revolabs HD Omni-directional Tabletop wireless boundary microphone.  Each Revolabs HD Base Station must be configured properly prior to use.  This device is only for Zoom and not for sound reinforcement in classrooms.  

To use the HD Wearable Microphone:

The Revolabs HD Wearable Microphones, shown in the following figure, are paired to the 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 or audio system.

  1. Earpiece jack — accepts the 2.5mm plug for the earpiece.
  2. Charging port — docks to Revolabs HD Charger Bases.
  3. Pocket clip — also used to attach the microphone to a lapel, blouse, or lanyard.
  4. Mute Button — Press to mute, un-mute, and pair microphone.
  5. Acoustic Cover — protects delicate microphone element (non-removable).
  6. LED display — visual status for mute, un-mute, and pairing.

Revolabs HD Wearable Microphones turn on and mute automatically when removed from Charger Base, to reduce noise while being attached.

  1. Remove the microphone from the Charger Base.
  2. Attach the microphone to clothing or to a lanyard, position microphone just above the sternum or breastbone, within 6 - 12 inches (15 – 30cm) from the mouth is recommended. Make sure the microphone is attached securely with the microphone LED indicator pointed up toward the mouth.

  3. With the microphone in the wearing position, un-mute the microphone by pressing and releasing the Mute button (confirm by a flashing GREEN LED). If the volume is too low, move the microphone closer to the mouth.

  4. To turn microphones off, return the microphone unit to the Charger Base or press and hold the mute button for ~10 seconds until the LED turns solid RED then release button.  Please make sure that the microphone is cleaned off with the appropriate cleaning procedure before returning to Charge Base (see below).  

    If the microphones are moved out of range of the Base Station (~150 feet or 50 meters) the connection will be dropped (LED flashes all red, green, yellow) and the microphone will mute.  After 15 seconds the microphone will beep 5 times and will continue beeping every 30 seconds to remind the user to return the microphone to the conference room. If the microphone is moved back into range within 15 minutes the connection will automatically be re-established to its original state, and the beeping will cease. If not, the microphone will turn off.

To use the HD Omni Tabletop Microphone:

The HD Omni-directional Tabletop Wireless Boundary Microphones enable multiple conference attendees to use a single microphone.Revolabs omni-directional

  1. LED display — visual status for mute, un-mute, and pairing.
  2. Mute button — Press to mute, un-mute, and pair microphone.
  3. Audio jack — accepts a 2.5mm plug. (not applicable)
  4. Charging port — docks to Revolabs HD Charger Bases.
  5. Rubber feet — non-slip, vibration-absorbing pads.
  6. Acoustic Cover — protects delicate microphone element (non-removable).

To use the HD Omni Tabletop Microphone:

  1. Remove the microphone from the Charger Base to turn on and automatically mute the mic. (indicated by a flashing RED LED)

  2. Omni Tabletop microphones can be centered on the table within 2 to 6 feet (0.6 to 2m) away from people speaking and do not need to be pointing in any particular direction because they pick up sound from all directions. For classroom application, please place in the center of the room on a table or desk.  It is always better 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 lying on its rubber feet atop a flat surface.

  3. With the microphone in position, un-mute the microphone by pressing and releasing the Mute button (confirm by a flashing GREEN LED).

  4. To turn the microphone off, 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 release button.  Please make sure that the microphone is cleaned off with the appropriate cleaning procedure before returning to Charge Base (see below).

    If the microphones are placed too far from the Base Station (~150 feet or 50 meters) the connection will be dropped (LED flashes all colors) and the microphone will mute. After 15 seconds the microphone will beep 5 times and will continue beeping every 30 seconds to indicating it’s out of range.

    Move the microphone closer to the Base Station and the connection will automatically be re-established to its original state, and the beeping will cease. If not, the microphone will continue beeping until it turns off in about 15 minutes.

Cleaning:  ITS recommends spraying the disinfectant solution onto a paper towel and then wipe down the equipment with the paper towel.  Remove excess moisture from the equipment and allow it to dry fully. Do not spray cleaning solution directly on the equipment. Sanitize hands before and after handling the equipment. 

Recharging — When the YELLOW LED starts to flash intermittently on the microphone the battery has 30 minutes of charge remaining. Overtime (years), batteries gradually wear down and will result in shorter run times. This is normal. Always clean and return microphones to the Charger Base when not in use.

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.

How to Configure Basic Settings

Each Revolabs HDTM Base Station must be configured properly prior to use. The accurate configuration is dependent on several variables such as:

  • 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.  Normal PC classroom usage would require Dip Switch 1 ON.
  • 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.  Normal PC classroom usage would require Dip Switch 3 ON.
  • DIP Switch 7&8 - Transmit Power: The transmit power of the Base Station can be adjusted to help reduce the operational radius of a Revolabs HDTM System in order to prevent interference from other Revolabs products, or from other devices operating in the same frequency. Note: It is recommended that the lowest functioning Transmit Power be used for each system. The actual range depends on RF signal absorption, reflection, and interference.  Normal PC classroom usage would require Dip Switch 8 ON.

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 the 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.

To pair an individual microphone to the Base Station: (the devices are already paired to the base station.  Current set-up - Port 1 - lavalier Port 2 - Omni-directional.

  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.
