Quick Start
Position the VH12 transmitter about 6-12" (15-30 cm) from the front of the SR412 receiver 
with the transmitter's IR window facing the IR transmitter on the front panel of the SR412 
receiver.
Press and hold the SR412 CH A SELECT button to set the transmitter to the same channel as 
the receiver via infrared transmission.
When the transmission is complete, the SR412 will receive RF signal and the tone-key (for 
more about tone-key read the section titled 
“All about squelch”) from the transmitter. The CH A
READY indicator will light on the front panel of the SR412 receiver. Repeat these steps for the 
remaining transmitters and receivers. The four receivers available frequency channels do not 
overlap, so you can set the four receivers to the same channel number.
Turn on your connected amplifier or mixer, but keep the volume all the way down. Set the 
Volume knob on the SR412 fully clockwise (to its “10” setting). This is unity gain. 
Speak or sing into the microphone. Slowly raise the volume of your amplifier or mixer until the 
desired level is reached. 
If you find the system has noticeable dropouts, reduced overall working range, or unexpected 
noise bursts, change the operating channel of the system using the steps above. 
When using multiple systems in the same frequency band, each system must be set to a different 
operating channel.
