Hybrid Electronic Noise-Cancellation Technology
Your DC ONE-X headset 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.

HYBRID ENC TECHNOLOGY
Proper Fitting
The advanced suspension system of the DC PRO-X is designed for
a simple and comfortable fit. Proper fit is necessary for maximum
effectiveness. The headset should be worn so that the head pad lightly
touches the top of the head. Adjust the sliding assembly on each
side as necessary (see Fig. 1), keeping slide positions equal on
either side, until the center of the ear phone aperture within the
ear seal is directly aligned with the ear canal.
The ultra-soft memory foam of the ear seal will conform to the
contours of the ear to provide an adequate seal. While in the presence
of noise, turn on the ANR circuitry and then adjust headset and ear
seal position for lowest noise heard, allowing optimum performance
of the Hybrid ENC technology for communications and music listening.
To adjust microphone placement, adjust boom up/down and in/out by
rotating and flexing the boom as necessary. Ideal microphone place-
ment is 1/8” from the lips, as this will provide maximum intelligibility
and ambient noise rejection. Fig. 1
