|Q||Why can't I access the narrow band channels on my transmitter?|
|A||The transmitter is in "Basic mode" and all narrow band channels are locked out. To enter "Expanded mode" and transmit on a narrow band channel, hold the channel select "Down" button while turning on the unit.|
|Q||Why is the signal being transmitted inconsistently and my receiver cuts in and out?|
|A||The receiver may be out of range of the transmitter.|
|Q||What can I do if my transmitter seems to have lost power/range.|
|Q||What is the range of the LT-800-216 MHz transmitter?|
|A||Line of site up to 914 m (3,000 ft.) with 216 MHz.|
|Q||Why can't I change the channel on my transmitter?|
|A||The unit is locked on a channel. To unlock, hold the channel select "Up" for 3 seconds. The padlock icon will extinguish from the LCD display.|
|Q||Can this transmitter be powered with a DC voltage?|
|A||Yes. The transmitter must use the supplied 12 VDC power supply.|
|Q||How many RF transmitters can I have operating simultaneously?|
|A||72 MHz: 8 simultaneous transmissions|
|Q||What does the LT-800 Transmitter "contour" knob do?|
|A||The contour knob boosts or cuts frequencies above 5kHz. It is recommended that this knob be turned counterclockwise for voice and clockwise for music.|
|Q||What does the LT-800 Transmitter "process" feature do? When should I use it?|
|A||The process feature is a type of Automatic Gain Control. If your input signals to the transmitter are inconsistent in level and you wish to have gain control, then this should be turned on.|
|Q||Where should I have the input level switches positioned on the back of my transmitter?|
|A||Depends on the level of audio being input. When using Input 1: • MIC position: For a microphone or MIC level input of -55dbu. • MIC Phantom Power: For a condenser microphone that needs a 12VDC phantom power supply at a -55dbu level input. When using Input 2: • +10dbu/SPKR position: When connecting a speaker or any other higher line level audio input. • -10dbu/Line position: When connecting a regular line level input of -10dbu|
|Q||Can I use the LT-800 transmitter with other manufacturer's receivers?|
|A||YES. Please refer to the frequency compatibility charts in the manual or on the website for channel conversions. When using other manufacturers products, SQ (Super Quiet) must be turned OFF.|
|Q||What channels should I be transmitting on?|
|A||It is recommended that wideband channels are used for best audio quality. If transmitting multiple simultaneous channels, narrowband frequencies may be required.|
|Q||Is there a limit to the number of transmitters I can use in one room?|
|A||Yes. The 72 MHz LT-800-072 has a maximum of (8) eight.|
|Q||Does the LT-800 include the rack mount?|
|A||No, but an LA-326 Universal Rack Mounting Kit is available for purchase.|
|Q||Do I need a transmitter for each audio source?|
|A||Each audio source requires a transmitter.|
|Q||How many receivers can I have on a system?|
|A||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".|
|Q||What is the range of the LT-800 transmitter?|
|A||Depends on the following:|
- The frequency of the transmitter.
- The transmitter's location.
- The antenna being used on the transmitter and receiver.
- The location of the remote antenna (if applicable). In general, the higher the antenna the more range.
- The length of coaxial cable ran to the antenna from the transmitter (if applicable). Every foot of cable creates a power loss.
- The RF power setting on the transmitter.
- The objects between the transmitter and receiver. All material, especially metal, will weaken the signal strength.
- When using 72 MHz, a direct line of sight distance of 305 m (1000 ft.) from the transmitter can be achieved.
|Q||What type of microphones can I use with the LT-800 transmitter?|
|A||Dynamic microphones can be used when the Input 1 level select switch is in the "MIC" position.Condenser microphones can be used when the Input 1 level select switch is in the "MIC + Phantom Power" position.|
