Hi Chris,
The main problem i am facing is the Microphone feedback. Which is the best vocal microphone with less feedback ? Is Shure 58A and Shure Beta 58A same ? which is better from both ? Are cordless microphones ok ? ...
Hi Sunny,
The correct name of the microphone I recommend and use myself is "Shure
Beta 58A". There is
no other model "Shure 58A" or similar. The Beta 58A has, as I said, a "supercardioid" characteristic. In the "Classic" Shure
SM58 has a normal "cardioid" characteristic.
Basically: For
supercardioid mics (e.g. Beta 58A), the monitor speakers should be positioned
laterally behind the mic (120°).
Standard cardioid mics (e.g., SM58), on the other hand, are least sensitive directly from behind, so for
standard cardioid mics, the monitor speaker should be right BEHIND the mic (180°).

https://pubs.shure.com/guide/beta58a/en-usIncidentally, I explicitly recommend a
dynamic supercardioid mic. Of course,
condenser mics (which require phantom power!) could also be used on the Genos. However, with these you are likely to have even more problems with feedback (especially at high frequencies).
Please note if you use a
compressor for the vocal mic: The more compression is used, the easier, feedback can occur, because a compressor makes the signal
quieter (as soon as it exceeds the threshold level). Therefore, the total volume of the mic must then be increased.
In addition, in live operation, a relatively low distance to the mic is necessary (from direct lip contact to a maximum of 10 - 15 cm). At a larger distance, feedback can easily occur (because the channel volume must then be increased).
Basically, in live operation you always have to take some compromises regarding the sound setting of mics. Normally one reduces the deep frequencies of a vocal microphone rather and does not use too much high frequencies. Above all, the mid-frequencies are important in live operation.
Wireless microphones often use a so called "Compander" circuit. That is, via the wireless connection, a highly compressed signal is transmitted, which is "expanded" again in the receiver. As a result, such systems are in principle more prone to feedback than
wired mics. This is especially true for wireless microphone systems that use
analogue (FM) technology.
Digital systems have a higher transfer bandwidth and usually do not have the disadvantage described. Basically, one can say: The high-quality (more expensive) a wireless microphone system is, the fewer feedback problems are to be expected.
Hope this helps!
Best regards,
Chris
