HYBRID ENC TECHNOLOGY
Hybrid Electronic Noise-Cancellation Technology
Your DC PRO-X2 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.

Enhanced Auto Shutoff
DC PRO-X2 Series headsets are shipped with the Enhanced Auto Shutoff feature set to the ‘ OFF ‘ position. Enhanced Auto Shutoff can be enabled/disabled via a small switch located under the batteries (see Quick Start diagram page 6).
When Enhanced Auto Shutoff is set to ‘ OFF ‘ (factory default), ANR headset power is manually controlled using the Power Button. When Enhanced Auto Shutoff is set to ‘ ON ‘, at turn-on of the headset using the Power Button, the headset will function as follows:
A. If the headset is connected to the aircraft audio panel, the headset will automatically turn off after 5 minutes under the following conditions:
• aircraft audio panel is turned off,
• headset is disconnected from the aircraft panel, or
• an active cell phone conversation is concluded.
B. If the headset is not connected to the aircraft audio panel, headset power is controlled by the Power Button, allowing continuous use for cell phone conversation or streaming audio. -
Cell Phone Interface
• Use of the Bluetooth® wireless technology cell phone feature while plugged into aircraft intercom is not recommended and may violate applicable regulations
• 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 always present
• Briefly pressing the Bluetooth® wireless technology button will answer or terminate a call (if supported by the cell phone)
• Cell phone receive audio is not muted when receiving a transmission from ATC or intercom -
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 listening to music briefly pressing the Bluetooth button will enable/disable muting:
• Flashing blue (default): When receiving transmission from ATC or intercom, music will mute to prioritize communication. Once transmission is completed, music audio will gradually return to the previously set volume level. A falling two-tone chime is heard when entering this mode.
• Flashing purple: Music will not mute when transmission is received from ATC or intercom. A rising two-tone chime is heard when entering this mode.
Each time the DC PRO-X2 is powered ‘ON’, this setting will revert to the default (muting) mode.
For DC PRO-X2 Aircraft-Powered Models Only
- Power is provided by the aircraft when using the 6-pin Redel® connector, or 5-pin XLR connector (11-30 VDC). Please note: Not all aircraft with XLR-5 connector provide power at pin 5. The batteries provided with the headset are only required when no power is available at pin 5, or when the headset is disconnected from the aircraft panel.
- When powered by aircraft, power LED will be solid green.
- If external power is lost, headset will revert to battery power.
- Headset will automatically turn on when external power is applied, without using the Power Button on the control module.
FITTING
Proper Fitting
The advanced suspension system of the DC PRO-X2 Series 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.
