Frequently Asked Questions - CM311 L AKG
How do I connect the CM311 L to a mixer or amplifier?
Connect the 3-pin XLR cable to the microphone's output and the other end to a mixer input. Make sure the 9 V battery is properly installed if the microphone does not receive power from another source.
How do I replace the 9V battery?
Locate the battery compartment on the belt-pack module, slide open the cover, remove the old battery, and insert a new 9 V battery with the correct polarity. Close the cover securely.
What is the recommended polar pattern for stage use?
The microphone has a cardioid polar pattern, which is ideal for stage use because it rejects sound from the rear and sides, helping to prevent feedback.
How should I clean the microphone grill?
Use a soft brush or a dry cloth to gently remove dust from the grill. Do not use liquids or solvents. For the windscreen, you can wash it with mild soap and water if necessary.
Can I use the microphone with a wireless system?
Yes, you can use the CM311 L with a wireless transmitter if you have a belt-pack transmitter that accepts a 3-pin mini XLR or a suitable adapter. Check the transmitter's input requirements.
What is the best way to position the microphone on my head?
Place the headband over your head and adjust the boom so the microphone capsule is positioned at the corner of your mouth, about 1-2 cm away. The microphone should not touch your face.
How can I reduce wind noise?
Use the supplied windscreen or foam cover over the microphone capsule to reduce wind noise. Also, avoid breathing directly into the microphone.
Does the microphone require phantom power?
The microphone can operate on a 9 V battery. It does not require phantom power, but some models may support it. Check the manual for your specific version.
How can I cancel feedback during a live performance?
To avoid feedback, keep the microphone pointed away from loudspeakers. Use equalization to reduce frequencies that cause resonance, and position the speakers in front of the microphone.
What are the spare parts available for the CM311 L?
Spare parts include windscreens, battery compartment covers, and headband pads. Contact an authorized AKG dealer for original replacement parts.
