FAQs

+What is the range of the LT-800-150 transmitter?

Up to 762 m (2,500 ft.)

+Does the LT-800-150 include the rack mount?

No, but an LA-326 Universal Rack Mounting Kit is available for purchase.

+Is there a limit to the number of transmitters I can use in one room?

Yes. The 72 MHz LT-800-072 has a maximum of (8) eight.

+Do I need a transmitter for each audio source?

Each audio source requires a transmitter.

+How many receivers can I have on a system?

As many as you want. The transmitter simply transmits a signal and you can have as many receivers pick that signal up as necessary. It's like a radio station transmitting and the receivers are the radios tuning into the "channel".
