Hybrid Electronic Noise-Cancellation Technology
Your DC PRO-X features leading-edge Hybrid Electronic
Noise-Cancelling Technology (ENC) with feed-forward
and feed-back technology for superior active noise
reduction. Feed-forward noise cancelling is accomplished through
an exterior microphone in the ear dome that is isolated from the
speaker. The exterior microphone acquires the noise before it gets
to the ear. Feed-back noise cancelling is performed by the internal
microphone placed near the speaker. The signals are then inverted
to produce a reverse, ‘anti-noise’ signal. This hybrid technology
results in unsurpassed active noise reduction performance.
