Tripp Communications Systems

The two-way system utilizes a digital transceiver operating on the 1.9 GHz unlicensed PCS band utilizing Frequency-Hopping Spread Spectrum (FHSS) techniques allowing interference free full duplex communication. The device employs a multiply layer security protocol consisting of a 40-bit (pin free) group subscription, 32-bit authentication and a 64-bit encryption scheme enabling secure conversations. The device makes it easy to pair and form groups via Near-field communication (NFC), Docking Station or Software Suite. It’s simple to operate with a Power, Talk and Volume Up and Down buttons. The system allows up to 10 simultaneous groups to operate in the same area. It’s powered via a removable non-proprietary rechargeable lithium-ion battery or via an optional 3 AAA alkaline battery compartment.

The device has a signal-to-noise ratio of 70 dB or greater and an audio frequency response of 40 Hz – 15 kHz (±3 dB). The device incorporates automatic battery charging circuitry to charge and maintain the lithium-Ion battery either via the micro USB port or via the docking station using the additional charging contacts on the bottom of the device.

The one-way system utilizes a digital receiver operating on the 1.9 GHz unlicensed PCS band utilizing Frequency-Hopping Spread Spectrum (FHSS) techniques allowing interference free one-way communication.

The receiver has a 3.5 mm TRRS CTIA compliant headphone connection allowing operation with a standard style headphones. It has a multifunction Green/White LED allowing On/Off, Charging and Battery status. The system has a signal-to-noise ratio of 70 dB or greater and an audio frequency response of 40 Hz - 15 kHz (±3 dB). The device incorporates automatic battery charging circuitry to charge and maintain the lithium-Ion battery either via the micro USB port or via the docking station using the additional charging contacts on the bottom of the device.

The System is capable of broadcasting audio over both the 72 MHz frequency and 2.4/5.0 GHz Wi-Fi frequencies, allowing users to receive the audio through a receiving device with ear speaker/headphones or directly to Bluetooth enabled hearing aids. The 72 MHz frequency is transmitted to a receiving device as defined below. The 2.4/5.0 GHz frequency is transmitted to personal smart devices such as cellular phones and tablets through a free application as defined below.

The LT-803-072-P1 Stationary 3-Channel RF Transmitter Package 1 (72 MHz) includes (1) LT-803-072 Stationary 3-Channel RF Transmitter (72 MHz), (1) LA-106 Telescoping Top Mounted Antenna (72 MHz), and (1) LA-304 Assistive Listening Notification Signage Kit. The stationary RF transmitter is capable of broadcasting on one of any three channels – A (72.100 MHz), E (72.900 MHz) or H (75.900 MHz).

The transmitter has a SNR of 62 dB or greater. The output power is adjustable to quarter, half or full. Channel tuning is capable of being locked. The device has an audio frequency response of 50 Hz to 15k Hz, ‘± 3 dB at 72 MHz. It has two (2) mixing audio inputs and the following audio controls: input level, mix level and an adjustable low pass filter (contour). The device has an audio processor that is capable of automatic gain control and limiting. The Listen LT-803-072-P1 is specified.
