Manual


architectural specifications
The radiator-emitter shall have a transmitting area of no less than 10,000 square feet (one carrier) or greater for each radiator specified when used with specified receiver. The radiator shall be powered via CAT-5 cabling and the RF from the transmitter shall be carried by 50 ohm coaxial cable. The radiator shall have three indicating LEDs for power, radiator standby and radiator fault indication. The radiator LEDs shall be deactivated after 30 minutes if there is no audio signal present from the transmitter. The radiator shall come in a white or grey color and shall include all of the mounting hardware capable of mounting the radiator on a wall, on a ceiling, in a corner, on a desk, on a mic stand or on a tripod. The Listen LA-140 is specified.

1. RF input connector - this is the connection from the LT-82 transmitter or from the output of another radiator.
2. RF output connector - use this to send the RF input to another radiator.
3. Delay compensation - allows you to set different delays so all radiators have the same timing.  This prevents drop-outs caused by signals out of phase.
4. LED illumination switch - use this to turn on/off the illumination of the front panel LEDs
5. Termination switch - use to terminate the coaxial cable
6. Power connection from LT-82 transmitter or optional power supply (LA-205)
7. Power connection to (optional) second radiator.
8. LEDs - three LEDs that indicate power, carrier present and cable fault.
9. Color – two different colors. Available in Grey (LA-140-GY) or White (LA-140-WH). Mounting brackets and supplied cables match the radiator.
