Ohma Mics 101


Which mic is right for me?

If you're just starting your recording journey, we recommend starting with the Ohma condenser mic. It is easy to use and difficult to make mistakes with. Moreover, you don't have to limit yourself to one type of mic - depending on the situation, you can mix and match ribbon or condenser mics to get the sound you want. No matter what, Ohma World microphones will make sure that your instrument is accurately captured so that you can create beautiful music.

What is a condenser mic?

The most common type of microphone is the condenser. It is easy to use and can be used for a variety of tasks, such as recording vocals or the sound of a live event. The Ohma Condenser has a cardioid polar pattern, which means it captures sound from one direction only. This makes it easy to point the microphone directly at the sound source, such as a singer or speaker.

What is a ribbon mic?

Ribbon microphones are known for their smooth, natural sound. They are often used in studios to record vocals, electric guitars, and acoustic instruments. Ribbon microphones are less common than condenser microphones, but they are gaining popularity because of their unique sound. The Ohma Ribbon microphone has a figure-8 polar pattern, which means it captures sound from two directions. This makes it ideal for recording two sources at the same time, such as a singer and a guitar player.

How do I care for my ribbon mic?

Ribbons microphones are more delicate than other varieties, but they are also more resilient than many people believe. The Ohma Ribbon microphone is especially secure while also allowing you to capture your sound's essence.

What kind of transformer does the Ohma condenser use?

The Ohma microphone gives your sound a beautiful color with its Cinemag transformer. This type of transformer is classic for voices and has been used on the majority of recordings, especially when it comes to voices, since the late 1950s.

What instruments are ribbon mics good for?

Ribbons are often a good choice for bowed string instruments, electric guitars, brass, woodwinds, drum overheads, and rooms. They also have a great proximity effect that can make your instrument sound bigger than ever before.

Do I need a special microphone stand?

No, any regular microphone stand will do. Just make sure it can hold the weight of the microphone, which is lighter than an SM57!

What does phantom-powered mean?

Phantom power is a type of power that is used by both our ribbon and condenser microphones. This type of power is what enables the microphone capsule to work. Phantom power voltage is typically around 48 volts and its sent through XLR cables. You only need a phantom power supply and an XLR cable, and you're good to go! Most XLR cables are balanced, which means that they have three conductors. The phantom power is sent through two of these conductors, and the third conductor is used as a shield.

Do I need a special type of XLR cable?

No, you can use any XLR cable. Just make sure it's long enough to reach from your phantom power supply to your microphone.

Do I need a special type of phantom power supply?

No, you can use any phantom power supply. Just make sure it's able to provide 48 volts.

Will the mic work with XZY audio interface?

As long as your interface or preamp has phantom power, your microphone should work with it. Ohma microphones are designed to have enough output to work with any preamp and interface.

Screen FAQ


How do the screens work?

Ohma's microphone screens come in different types, each with a unique frequency response. This way, you can find the perfect screen for your needs, whether you want to change the look of your mic or alter the sound.

Why do you use screens instead of a regular grille?

The regular grilles on microphones are made of mesh that you can find at a store. This mesh looks plain and does not give you precise control over the sound entering your microphone. We use screens that are designed to look and work the same every time.

How do you change the mic screens?

The mic screen is easy to switch out. You just need the included guitar pick and a few seconds of your time. So if you want to change the sound of your mic during a recording session, it's easy to do. Just grab your Ohma guitar pick and pop the old screen out, then replace it with the new one.

How many mic screens are available?

We have 5 different screens available now. We are always developing new screens that we will release in a limited drop and/or as a future standard option.

How does the screen affect the sound of the mic?

The sizes, shapes, and patterns of Ohma screens all have a direct and significant impact on the sound of the mic. They act as an acoustical filter that changes how the sound enters the microphone. They can make the treble louder or softer, make the midrange higher or lower, increase or decrease the bass, and so on.

Does the color of the screen fabric affect the sound?

Nope! The color of the fabric has no impact on the sound of the microphone.

Can I buy screens separately from a mic?

Yes, we offer black, white, and stainless steel screens in a collection of four for $49 or as an individual replacement screen for $25.

How are the screens secured in the mic?

The screens are held in place by a steel surround that is attracted to magnets in the microphone body. It is very sturdy and requires a thick gauge pick to pluck them out. A regular guitar pick will not be strong enough. We include a pick with each microphone.

What is the purpose of the frequency response chart?

The frequency response chart is a visual representation of how the mic screens change the sound of the microphone. It shows you how the treble, midrange, and bass change with each screen.

What if I lose a screen?

Don’t worry, we offer black, white, and stainless steel single replacement screens for $25 and the whole set of four for $49.
