Frequently Asked Questions - Radius 100H ALTO
How to connect the Alto Radius 100H microphone?
Connect the male XLR cable of the microphone to a microphone input on your mixer or audio interface. Make sure the channel is properly set (gain, volume).
The microphone produces no sound, what to do?
Check the XLR cable connection, ensure the channel is enabled and the volume is sufficient. Test with another cable or input.
How to clean the Alto Radius 100H microphone?
Use a soft dry cloth for the exterior. For the grille, use a soft brush or an air blower. Avoid any liquid.
What type of cable to use?
Use a good quality male-female XLR cable. The recommended maximum length is 15 m to avoid signal loss.
Sound is low or distorted, why?
Check the gain on your mixer. Too low gain gives weak sound, too high gain causes distortion. Speak about 10-15 cm from the mic.
The mic picks up too much ambient noise, how to reduce?
The mic has a cardioid polar pattern: speak directly in front of the capsule. Move lateral sound sources away. Use a pop filter if needed.
Can I use this mic with a computer?
Yes, with an audio interface or XLR to USB adapter. Some computers have a mic jack input, but an XLR to 6.35mm jack adapter is needed.
How to maintain the mic grille?
Unscrew the grille if possible and clean it with mild soapy water, then dry it completely before reassembling. Otherwise, use a brush.
Does the mic work without power?
Yes, it is a dynamic microphone that does not require phantom power. It produces its own electrical signal.
Where to find spare parts for the Radius 100H?
Contact Alto after-sales service or an authorized dealer. Common parts like the grille or clip are available online.
