1. Introduction You are now the happy owner of the AU-800 LTO wireless system. Your AU-800 is based on a new revolutionary UHF PLL (phase loop locked) circuit which allows the simultaneous use of 144 different channels (depending on your country regulations). The Receiver is provided with 2 antennas that constantly monitor the incoming RF (radio frequency) signal and send only the stronger RF signal to the AU-800 Receiver.
Type: Dynamic Mic.
AU-800P: A bodypack transmitter with belt clip. The bodypack transmitter will come with either: 1. A cable to be connected to an electric guitar or bass. 2. A Lavalier Microphone. This is the little "bug" to be clipped on ties, shirts, nipples, etc. 3. A Headset Microphone that is fit like a pair of sunglasses so that the player has both hands free to play an instrument, dance, shot the audience, etc. HM-38, Condenser microphone Preset impedance: 600ohm; Freq.

2 UP/DOWN Keys: You can adjust the right values through these two keys once the MENU is activated. 3 Display: All the key functions of your AU-800 Receiver are monitored through this big, sexy, blue back lighted display such as: Radio Signal, Audio Signal, Battery life ( yes with some little magic you can see the battery life of the transmitter directly on the receiver!), group value, channel value and the selected frequency. 4 MENU Key: Via this key you can activate the desired function described above.
1 Front Grill: This spring steel mesh grill will protect the microphone capsule during a live performance. Especially made for heavy metal players, alcohol, drugs, etc. 2 LCD Display: This nice blue LCD will indicate the current operation status. 3 CH/ON Key: If you press this key for a few seconds, your Transmitter will switch ON or OFF. Once you have switched the unit ON, just press this key again slightly and you can edit various parameters such as CHANNEL, GROUP, RF POWER LEVEL and LOCK/UNLOCK.

Once you have switched the unit ON, just press this key again slightly and you can edit various parameters such as CHANNEL, GROUP, RF POWER LEVEL and LOCK/UNLOCK.
4. Operation OK, if so far you remember all the functions and features of your AU-800 system you are ready to operate the Unit. Let's start from the Receiver: 4.1 For the AU-800R, PLL UHF Diversity Receiver G F A B D C E A.This indicates the Frequency Group. There are 12 Groups and each Group includes 12 different channels (frequencies). B.This indicates the Channel Number. There are 12 channels for each one of the 12 Groups for a total of 144 channels. C.
During this process the audio output will be muted and the display will show you the Group Number scanned, the channel number scanned and the frequency that is being scanned. Once the transmitter frequency has been found, the display will flash and the RF bar indicator and Battery life icon will appear. Press MEM again slightly and such frequency will be stored into your AU-800R Receiver. Please note that frequencies can be scanned manually using the UP/DOWN key. See the Annex for more details.
No. 1 squelch threshold 95.0dB 2 3 91.7dB 4 85.0dB 5 6 81.7dB 78.3dB 7 75.0dB 8 9 71.7dB 68.3dB 10 65.0dB 88.3dB Fig 4 Table 4.2 For the AU-800H/800P transmitters Press the CH/ON key for a few seconds and the transmitter will be powered ON.
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 mainly of Countries regulations. We offer frequencies from 470 to 900 MHZ. Some of these frequencies are illegal in certain Countries and vice versa.
- LOCK Function You don't want accidental change of frequency or other setting in the middle of a performance, do you? Any miss-operation during a live performance can be easily avoided thanks to the LOCK function. With the LOCK function ON no further change of setting is allowed until the Transmitter is unlocked. To access the LOCK menu press the CH/ON key four times and then press the SELECT key to lock or unlock the Transmitter Settings.

6. Annex Frequency Band Selection: Most countries closely regulate the radio frequencies used in the transmission of wireless information. These regulations state which devices can use which frequencies, and help to limit the amount of RF(radio frequency)interference in all wireless communications. To be flexible enough to operate worldwide, AU-800R Wireless receivers are available in a number of models, each with a unique frequency range.
Remark: 1. The values with underlines should be scanned manually by adjusting UP/DOWN key. 2. The following channels can be used simultaneously without any interference. Group 1-1: 798.125 Group 2-1: 798.325 Group 2-2: 800.725 Group 2-5: 807.925 Group 3-4: 805.725 Group 5-1: 798.925 Group 5-8: 815.725 Group 7-1: 799.325 Group 8-6: 811.525 Group 12-2: 802.725 F8: 850.000~874.000(850~879)MHz Group1 Group2 Group3 Group4 Group5 Group6 1 850.125 850.325 850.525 850.725 850.925 851.
