BV18 Transformer

Description

Advanced Audio BV18 Transformer

Used in Advanced Audio Microphones CM12se:

The CM12se utilizes a larger BV18 dual-bobbin transformer with an 8:1 ratio as opposed to the 5:1 ratio of the BV11 used in our CM12. The larger BV18 tranformer can handle 3dB more level then the BV11 before distortion and has 3dB less output. When close miking percussive sound sources the CM12se will recover faster from a larger transient signals and drive the microphone preamp with 3dB less level than the CM12 when placed in the same position.

The BV18 transformer is driven through a 2.2-ufd mylar capacitor to take advantage of the ability of both capsule and transformer to respond to frequencies reaching down to 10Hz. The transformer can deliver +18dBm with less than 1% distortion across the audio spectrum.
