HYBRID ENC TECHNOLOGY
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.

and earphones will function when connected to aircraft intercom.
7. Music Listening
• The Bluetooth wireless technology feature allows you to listen to your
favorite music when paired with cell phones, MP3, tablets, or other
compatible devices. When receiving transmission from ATC, music audio
will mute to prioritize communication. Once transmission is completed,
music audio will gradually return to the previously set volume level.

In this mode, the Hybrid ENC will function whenever the power is ON.
3. When Auto Shutoff is set to ON, unit will turn off automatically after 5
minutes when:
• Intercom/audio panel turned off
• Not connected to intercom/audio panel
• Not in a phone call
4. Auto shutoff can be enabled/disabled via a small switch located under
the batteries (see Quick Start diagram page 6).
5. External Audio Management
• Aux audio is muted upon transmit or receive from intercom or radio
to ensure priority of audio voice communications
6. Cell Phone Interface
• All intercom parties hear cell phone outbound audio but cell phone
recipient’s voice is heard only by the headset connected/paired to
the cell phone
• Sidetone is present when connected to aircraft intercom. Sidetone may
not be (dependent on cell phone functionality) present when using the
headset and cell phone when not attached to the aircraft intercom

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.
To adjust microphone placement, adjust boom up/down and in/out by
rotating and flexing the boom as necessary. Ideal microphone placement is 1/8” from the lips, as this will provide maximum intelligibility
and ambient noise rejection. Fig. 1
