The new TCI™ Liberator® IV, V, and HP headsets meet law enforcement and special operations forces’ current demands and requirements.
Liberator® headsets’ key features include electronic hearing protection to provide full-spectrum environmental sound and incoming radio communication simultaneously. The multimode dual processor design includes active noise cancelation (ANC) to add additional electronic protection against steady-state noise. A combined mode pairs the two processors to provide the end-user complete electronic protection against both impulse and steady-state noise. The Liberator® series tactical headsets have been deployed by the Department of Defense, law enforcement agencies, and security teams during missions in Afghanistan, Iraq, and worldwide. Thousands of systems are currently in service today, and thousands more will be deployed locally and around the world in the future. All Liberator® headset systems are designed, engineered, and manufactured in Ontario, California.
Liberator® tactical headsets exceed military durability standards with earcups made from durable Safari 7 TM glass polymer, which offers scratch-resistant protection and exceeds the high and low-temperature thresholds of current headset earcups. The Safari 7 TM glass polymer is the same type of material that Safariland® uses for its 7TS holsters systems. The headset features multimode digital hearing protection for all sound environments, high-battery life from a choice of two battery types, low-profile earcups, state-of-the-art digital sound processing for optimal reproduction of environmental sounds, and leading radio frequency (RF) and time delay multiaccess (TDMA) shielding for using advanced digital waveforms such as ANW2. TCI™ utilizes an exclusive Advanced Digital Threat Compression Technology (ADCTC) that compresses hazardous sound levels while providing the user with continuous situational awareness, communications, and the best replication of ambient sound. The TCI™ Advanced Digital Situational Awareness Enhancement technology (ADSAE) provides the user with precise sound localization and proximity of ambient sound to maximize the user’s effectiveness and safety. The headsets also feature an active noise cancelation (ANC) mode to provide an additional 5-8dBa reduction above the steady-state 25dBa (25NRR) offered passively by the earcups themselves. The third mode of operation combines ADCTC and ANC modes to provide electronic protection against steady-state noise and impulse noise.
Additionally, in this mode, the headset features a speech isolation mode that isolates close proximity human speech out of the background noise, processes it, and replicates it inside the earcup allowing end-users to communicate face-to-face without the need for an intercom. The modern electronics on this headset are firmware updatable using near field communications (NFC) protocols. These progressive attributes and an array of others enable Liberator® headsets to be ideal for tactical missions. Liberator® headsets provide the performance necessary to support operator concentration, safety, mission completion and reduce user fatigue.
The Liberator® IV and V Tactical Headsets provide exceptional communications and electronic hearing protection during typical and critical situations. The ability to maintain peripheral hearing and amplify potential danger signs and audio clues from the environment are unique features of Liberator® systems and necessary for tactical missions. The electronic hearing protection of Liberator® V systems is the most advanced available. Less progressive systems “clip” or “cut-off” ambient sounds while the hearing protection is activated, impeding situational awareness for the user and often negatively affects incoming communications. On the other hand, Liberator® systems compress and reduce hazardous sound to safe levels inside the headset without muting ambient sounds or incoming radio communication audio. The TCI™ ADSAE technology provides 360 degrees of ambient sound reproduction. This technology is the most accurate method of environmental sound replication, threat identification, and threat localization. It uses dual external microphones that continually process ambient sounds and instantaneously compress impulse noise. With up to 29 dBa of attenuation, the headset protects the user from exposure to harmful static-state and impulse sounds by compressing dangerous sound levels to approximately 82 dBa. The headsets feature a fixed behind-the-head comfort fit, and the headset suspension provides a comfortable fit with any helmet type. The rigid band is situated low enough to not conflict with different nape pads or ratchet-style helmet suspension systems. The band is also adjustable to allow for the best fit possible.
Liberator® IV Tactical Headsets come with compact single-channel tactical Push-to-Talk (PTT), with a quick disconnect radio interface cable. These radio interface cables are the same cables used on the TCI™ Liberator® 3 & 5 dual comm systems. The system includes a factory mutually approved radio interface connection, assuring the connection precisely meets radio model specifications. This model provides radio interface cables for military radios using a U329 connection and for the Motorola® XTS® 5000/PRC153. The switch is protected inside the PTT housing and is easily accessible in all conditions and wearing gloves. The raised PTT enclosure protects the switch from accidental activation. This PTT is ambidextrous, includes a 17″ coiled radio cable, and requires no end-user modification. This Liberator® V tactical headset comes with a compact dual tactical PTT and a compact single-channel PTT. Both PTT devices utilize the same common quick disconnect cables, including a factory mutually approved radio interface connection, assuring the connection precisely meets radio model specifications. The dual communications PTT is wired TEMPEST compliant and includes features to prevent accidental transmission of potential classified traffic over an unclassified radio net. The enclosure and custom aerospace aluminum switches are IP68 rated and have a cycle count of 1 million activations. The switches feature a raised tactile indicator for high and low bands and are easily distinguished in all conditions and wearing gloves. The single communications PTT is a modernized U94 form that is waterproof and features an ambidextrous MOLLE clip. This package allows end-users to conduct single-channel communications without the hassle of a deactivated PTT switch or unused open connections.
A zipped padded storage bag is also a standard feature for Liberator® systems.
