A low noise circuit combined with noise suppression circuitry produces crystal clear speech.

• Automatic Gain Adjustment

Guards against audio signal distortion to enhance audio quality – increases bandwidth 47%.

• Extended Battery Operation Time

The state-of-the-art Class-D digital audio power amplifier provides very low power dissipation, produces less heat, and extends battery life up to 32%.

• Flexible Gain Settings

Adjustable gain settings on the amplifier card support different communication applications and environments.

• Ultra-Low Electromagnetic Interference (EMI)

Ultra-low EMI emissions achieved through spread-spectrum and de-phase control techniques provide for interference-free integration with other diving systems.

• Outdoor Rated AC Power Module

Weather resistant, IP65 rated AC power entry module accommodates country specific AC power cords.

• Country Specific V-Lock AC Power Cord

At time of order, simply choose the IP54 rated Locking AC power cord you need.

FEATURES:

Inhalation Noise Reduction (INR) allows the user to adjust or completely remove each diver’s inhalation noise.
Each diver has an individual INR adjustment control and LED indicator to control the level of noise reduction desired.
INR LED indicators illuminate when the INR function is actively removing the diver’s inhalation noise.
Diver umbilical connections on the front panel are 5-pin MS (Military Standard) connections.
Separate channels and volume controls for each diver and the tender allow individual earphone and microphone adjustments, equipment variations and comfort levels.
Weather resistant IP54 rated AC power module accommodates different country-specific V-Lock AC power cords, selected by the customer at time of order. Additional power cords can be ordered separately.
Support for 4-wire mode (full duplex) or 2-wire mode (push-to-talk) or any combination of the modes for any of the diver circuits.
Use dynamic or pre-amplified diver microphones – a unique circuit detects microphone type and automatically adjusts volume levels.
Weatherproof noise cancelling push-to-talk microphone for better tender voice intelligibility. For optimum clarity, see Tech Note(below) for other recommended equipment.
Internal charger supports charging and operation at the same time, prevents over-charging, and automatically switches to battery power when AC power is disconnected without interrupting operations.
Ultra-low EMI emissions provide for interference-free integration with other diving systems.
