The 44-A Ribbon Microphone from Cloud Microphones is the first and only active ribbon microphone with switchable Voice/Music response curves, reminiscent of the early RCA mics, for controlling proximity effect. A switchable interface that provides dual frequency response voicing in an active ribbon microphone is very useful in a wide variety of scenarios. Voiceover artists and singers can use the "Voice" setting to instantly reduce the large bass proximity effect associated with being close to the microphone. The "voice" position can also be useful for reducing intense low frequencies when using the mic to capture an instrument at close range, or where they may be rumble or vibration noise present. Some vocalists will prefer the larger bass response at close proximity. Therefore, having the switchable interface affords the user a microphone with two distinct voices, inviting the special sound of a ribbon microphone to be used with a variety of new sources that may not have otherwise been desired.
