The chief task of a CMC microphone amplifier is to convert the extremely high impedance signal from the capsule to a very low impedance one suitable for transmission through a microphone cable. Several versions are available which differ only in their powering, connectors, output levels and surface finishes.
They all feature a symmetrical class A output stage with neither coupling condensers nor an output transformer. This design helps them to achieve extremely low distortion and light physical weight, while their very low output impedance helps make them insensitive to electrical interference.
- balanced, very low impedance output
- Works with both 12 V and 48 V phantom powering
- can be used with very long cables (several hundred meters)
- can be used with Active Accessories for miniaturization and special applications
