IR SYNC

Each mic will need to be paired individually and one at a time for proper syncing.

button for 1 second and release. The receiver will send out an IR (infrared) signal, place the 
handheld mic’s IR port close (2-8") to the receiver's IR port.  During pairing, the LED segments 
will illuminate in a clockwise manner.  When the LEDs stop rotating release the "Select" button.  
After releasing the "Select" button, the LED segments will continue to rotate clockwise until 
paired. The RF light will illuminate green on the receiver when a successful sync between the 
receiver and transmitter is complete.

The receiver and mic will revert to previously selected channel when powered back on.  To 
change the channel at any time, turn the mic off and press the "Select" button to increment to 
the desired the channel number.  When you reach the desired channel, release the button and

"Select" button, when the RF light illuminates you have successfully paired the mic and receiver.  

Labeling or differentiating mics will help with channel confusion, this can be done effectively 
with separate color coordinated tape or other unique indicators. If confusion about mics and 
corresponding channels occurs, pairing the mics again will "reset" channels.

CHANGING BATTERIES

The handheld mic is powered by 2 AA batteries.  Batteries are housed at the bottom of the mic.  
To remove the battery compartment cover unscrew the bottom battery cover of the mic.  When 
replacing batteries be certain to install batteries in proper polar direction. Battery life of the 
TWUH2 is about 8 hours of continuous use.

speaker, take either output to the corresponding input on external gear. The receiver features

output the both channels in one unbalanced output.

Ensure that the volume on the external gear is completely down while plugging in the receiver 
to prevent loud electrical pops that can damage speakers. 

SETTING VOLUME

The AF LED will blink RED when signal is present to the receiver from the mic. To set the volume 
the receiver sends to your external gear adjust the volume knob on the receiver so that the input

representing the external gear's input signal is steadily green without turning red - a sign of clipping 
and causing audible distortion. 

Each channel has an individual volume knob for adjustments.  

Best practices include starting with the receiver's volume all the way down (turned to the left) and 
raising in small increments until an adequate audio level is achieved. If the external gear you are

it is also best practice to set the input gain to 12 o'clock with the output volume fader or pot at a 
nominal 0dB volume.  This will allow you to increase the volume of the mic channel on the external 
gear instead of having to use the receiver's volume knob to increase or decrease level. 

MICROPHONE CONTROL

To turn the mic on, slide the ON/OFF switch to the ON position.  When paired with the receiver 
and the mic is in the ON position, the receiver should have signal to send to external gear. To turn 
the mic off, slide the switch to the OFF position.  The mic also features a MUTE function in which 
the mic will not send signal but remain powered on.  To access this function slide the switch to the 
middle position.  When the mic is ON or in MUTE, a blue light illuminates on the mic.
