Introduction Congratulations on purchasing the Samson Stage 412 Quad Microphone Wireless System! The Stage 412 system is the perfect solution for any application requiring four high quality, wireless microphones in an easy to use package. Featuring simple operation, with 12 available channels and infrared set for the transmitter channel, the Stage 412 can quickly be up and running out of the box. The system includes the SR412 Quad channel receiver with individual and mixed outputs.

Quick Start In order for your wireless system to work correctly, both the receiver and transmitters must be set to the same channel. Follow this basic procedure for setting up and using your Stage 412 wireless system: Physically place the SR412 receiver where it will be used, and fully extend the antennas vertically. The general rule of thumb is to maintain “line of sight” between the receiver and transmitter so that the person using or wearing the transmitter can see the receiver.
Quick Start With the transmitter powered off, install two fresh AA batteries into VH12 handheld transmitter. Leave the battery compartment open. Turn on the power to the transmitter by pressing and holding Power switch; the indicator LED will light green. Press the CH A SELECT button on the front of the SR412 to choose an available channel for the CH A receiver. The channel number will increase by one digit, from 1–6. Once the last channel has been reached, the count will cycle back to 1.
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.

All about squelch Squelch (or muting) circuitry acts to silence the audio output of the receiver whenever the desired RF signal is not present. If such circuitry is not present, the receiver may output a different signal—or even extremely unpleasant white noise—whenever the RF signal is lost due to dropout or excessive distance, or when the transmitter is turned off.
Troubleshooting Issue Solutions Turn on the VH12 transmitter using the Power/Mutr switch. Ensure the VH12 transmitter’s batteries are installed correctly. Confirm that the SR412 adaptor is correctly connected and plugged into an electrical outlet. No Audio Turn on the SR412 receiver. Make sure the SR412 output and audio input connections are securely connected. Ensure that the SR412 receiver and VH12 transmitters are in line of sight with one another.
