2.3 MICROPHONES

The AudioBox USB works with many microphones including dynamic, ribbon and condenser

microphones.

2.3.1 Condenser

Condenser microphones tend to generate a high-quality audio signal and are one of the most

popular mic choices for today’s studio recording applications. Because of their design

technology, condenser microphones require a power source, which can be provided from a small

battery, external power supply or from microphone inputs as

phantom power.

The AudioBox

USB sends phantom power over XLR inputs only.

2.3.2 Dynamic

Dynamic microphones are possibly the most widely used microphone type – especially in live

shows. They are relatively inexpensive, resistant to physical damage and typically handle high

sound pressure levels (SPL) very well. Unlike condenser microphones, dynamic microphones do

not require a power source and, in most cases, has no effect on a dynamic microphone’s audio

quality or sensitivity.

Dynamic microphones, especially ribbon microphones, tend to generate low output voltages, so

they typically need more preamp gain than a condenser microphone.

Ribbon

Ribbon microphones are a special type of dynamic microphone and get their name from the thin

metal ribbon used in their design. Ribbon microphones have very high quality sound reproduction

qualities –

especially higher frequencies sounds. However, they are very fragile and typically

cannot handle high SPL’s.

The most important thing to note about Ribbon microphones is that nearly all

Ribbon

Microphones do NOT require phantom power.

In fact, unless a Ribbon microphone specifically

calls for phantom power, sending

phantom power to a ribbon microphone will destroy it – usually

beyond repair.
