Note: Why LTO wireless systems come with 144 different frequencies?

Not because you will need to use 144 different microphones at the same

time. It is unlikely that you will use more than 8 systems at the same

time so why 144 frequencies? This depends on Countries regulations.

We offer frequencies from 470 to 900 MHZ. Some of these frequencies

are illegal in certain Countries and vice versa. Offering such a wide range of

frequencies we make sure that each single Country on the planet will

have more than enough choice of frequencies available. Not only: A

certain frequency is close to the frequency generated by lighting equipment,

a computer, a fax machine and so on. Therefore, thanks to the large

number of frequencies available you can easily switch to another frequency

that is interference-free.

mainly

In your Transmitter, there are 12 frequency bands or GROUPS. Each Group

contains 12 channels according to EMC regulations.

To select a Group you must first switch your Transmitter ON by pressing the

CH/ON key for a few seconds until you hear the beep and the blue display is

lighted. Then press the CH/ON key again slightly and you will access the GROUP

menu. At this point use the SELECT key to change the GROUP value from 1 to

12. Now, to access the CHANNEL menu, press again slightly the CH/ON key

two times and use the SELECT key to change frequency from 1 to 12. Your

setting will be automatically saved in a few seconds and the display will go back

to the main menu showing the operating frequency.

Note: Once you have changed the operating frequency on your Transmitter,

you need to activate the SCAN function in your AU-800R Receiver. In this way,

the Receiver with synchronize automatically on the Transmitter frequency.
