QUICK START
In order for your wireless system to work correctly, both the receiver and transmitter must be set to the same channel.
Follow this basic procedure for setting up and using your Stage 212 wireless system:
- Physically place the SR212 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.
- With the SR212 powered off, connect the included power adapter. Turn the SR212 on momentarily to confirm that the unit is receiving power. You’ll see the LED display light up. Then turn the SR212 power off.
- With your amplifier or mixer off and volume control all the way down, connect the SR212 receiver 1/4” outputs (or XLR Mix Output) to the inputs of a mixer or amplifier. Turn the Level knob on the SR212 completely counterclockwise, then turn its power on.
- With the transmitter powered off, install two fresh AA batteries into VH212 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 SR212 to choose an available channel for the CH A receiver. The channel number will increase by one digit, from 1–9 then A–C. Once the last channel has been reached, the count will cycle back to 1.
- Position the VH212 transmitter about 6-12″ (15-30 cm) from the front of the SR212 receiver with the transmitter’s IR window facing the IR transmitter on the front panel of the SR212 receiver.
- Press and hold the SR212 CH A SELECT button to set the transmitter to the same channel as the receiver via infrared transmission
- When the transmission is complete, the SR212 will receive RF signal and the tone key from the transmitter. The CH A READY indicator will light on the front panel of the SR212 receiver. Repeat these steps for the CH B transmitter and receiver. CH A and CH B available frequency channels do not overlap, so you can set the two receivers to the same channel number or letter.
- Turn on your connected amplifier or mixer, but keep the volume all the way down. Set the Volume knob on the SR212 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.

FAQs
Can two wireless mics be used simultaneously?
No. When setting up wireless microphone systems, a specific receiver is required for each microphone that will be used. To communicate with one another, the receiver and the microphone need to be on the same frequency.
Can many wireless mics be used simultaneously?
One active microphone transmitter at a time can only have its signal demodulated by a wireless receiver. However, as long as only one transmitter is turned on at any given time, you are free to utilize either on
What occurs if two microphones are using the same frequency?
Due to the receiver’s inability to discriminate between different signals, if two microphones are utilized simultaneously on the same frequency, they will interfere with one another.

Due to the receiver’s inability to discriminate between different signals, if two microphones are utilized simultaneously on the same frequency, they will interfere with one another.
What is the range of a wireless microphone?
The typical range for systems of the kind detailed here (10-50 mW, VHF or UHF) can range from 100 feet to 1000 feet.
How much energy is consumed by a wireless microphone?
In contrast to wireless microphone systems, which typically have an output power of only 50 mW (fifty one thousandths of one watt! ), television transmitters can operate at power levels up to one million watts.
Can any receiver be used with a wireless microphone?
No, as wireless microphones may employ incompatible frequencies, exclusive noise reduction circuits, and safe 128- or 256-bit encryption, they will NOT function with any receiver.
Can two microphones be connected to a single input?
It is not advised to use a Y cable to connect two sources, such as microphones, to a single input due to inappropriate impedance matching.
Can you plug two microphones into the input?
It is not advised to plug multiple microphones into a single mixer input when using them in simultaneously for music, recording, or conference purposes.
What occurs if you use an unauthorized frequency?
If you use wireless microphones or other equipment in the 600 and 700 MHz airwaves illegally, the FCC may punish you or take other legal action.
Why does phase cancellation occur?
When two signals at the same frequency are out of phase with one another, phase cancellation occurs, which results in a net decrease in the combined signal’s overall intensity.
How can phase cancellation be stopped?
The best technique to prevent phase cancellation in a mix is to move your microphones while you’re recording.
Why use two microphones when singing?
For noise cancellation, use two microphones. The ambient noise from each will be partially cancelled if the outputs of the two devices are combined at equal strengths but with opposing polarity.
