The Listen LT-800-216-01 Stationary RF Transmitter is a 216 MHz assistive listening transmitter designed to send audio from a sound system to compatible Listen RF receivers. It provides 57 selectable channels, adjustable RF output power, balanced and unbalanced audio inputs, audio processing, and a transmission range of up to 3,000 feet (914 m) with an appropriate antenna and installation.

Designed for assistive listening, language interpretation, and wireless audio distribution, the LT-800-216-01 is well suited for theaters, houses of worship, classrooms, lecture halls, conference facilities, auditoriums, and other venues requiring reliable RF audio transmission.

The transmitter operates from 216.0125 to 216.9875 MHz and provides 19 wideband and 38 narrowband channel selections.

57 Selectable 216 MHz Channels

The LT-800-216-01 provides 57 selectable RF channels:

• 19 wideband channels
• 38 narrowband channels
• 216.0125–216.9875 MHz operating range
• Up to five simultaneous transmitters

Multiple channel options give system installers flexibility when configuring assistive listening and other RF audio systems.

Up to 3,000-Foot Transmission Range

With the appropriate antenna and installation conditions, the LT-800-216 provides a transmission range of up to 3,000 feet (914 meters).

RF output power can be set to low, medium, or high, allowing the system to be configured according to the size and requirements of the venue.

A BNC 50-ohm antenna connection accommodates compatible external antenna options.

Balanced Mic/Line and Unbalanced Audio Inputs

The LT-800-216-01 provides flexible audio connectivity for integration with commercial and professional sound systems.

Audio Input 1 uses a balanced XLR/1/4-inch combination connector and can accommodate line-level, microphone-level, or microphone signals requiring 12V phantom power.

Audio Input 2 provides unbalanced RCA connections with selectable input levels.

This allows the transmitter to receive audio from mixers, microphones, playback systems, and other compatible audio sources.

Built-In Audio Processing

Integrated audio processing provides adjustable compression for managing transmitted audio.

Compression can be switched on or off, with an internally adjustable compression ratio from 1:1 to 4:1 and a default setting of 2:1.

A contour control adjusts frequencies above 5 kHz, providing additional control over the transmitted audio.

Look & Listen™ LCD Display

The front-panel Look & Listen LCD provides system information including:

• Selected channel
• Channel lock status
• RF power level
• Programming status

Front-panel audio level indicators display Input 1, Input 2, and mixed audio levels using 10-segment LED meters, helping installers set appropriate operating levels.

Built-In Test Tone

A built-in test tone simplifies system setup and testing.

The test tone can be enabled directly from the front panel, with a red indicator showing when the function is active.

Headphone Monitoring

A front-panel 3.5mm headphone output allows the operator or installer to monitor the audio being sent through the system.

Headphone level is independently adjustable from the front panel.

Physical and Power Specifications

I cleaned up that confusing weight area too. Your source gives 2.6 lb for the transmitter itself and 3.5 lb with the power supply, so both can be useful as long as they're labeled correctly.
