Q |
Can this transmitter be powered with a DC voltage? |
|
A |
Yes. The transmitter must use the supplied 12 VDC power supply. |
Q |
The signal being transmitted is inconsistent, my receiver cuts in and out. |
|
A |
The receiver may be out of range of the transmitter. |
Q |
I can't change the channel on my transmitter, help? |
|
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 |
I can't access the narrowband channels on my transmitter, help? |
|
A |
The transmitter is in "Basic mode" and all narrowband channels are locked out. To enter "Expanded mode" and transmit on a narrowband channel, hold the channel select "Down" button while turning on the unit. |
Q |
My transmitter seems to have lost power/range. |
|
A |
Make sure that the antenna is connected properly. Make sure that the RF power switch is in the correct position. A more efficient transmit antenna may be needed. |
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. |
