3. Control Elements

Ok, enough with numbers. Let's start to familiarize with your MOD-800 System. First of all, the MOD-800R Receiver:

3.1 MOD-800R, PLL UHF Diversity Receiver

THE FRONT PANEL

① Power Switch: We are afraid you can not use the MOD-800R if you don't switch the Power ON.

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 MOD-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.
⑤ MEM Key: You can enter the selected frequency via this Key, moreover you can also activate the AUTO-SCAN function via the same key.
⑥ Antenna Input Sockets: Yes, you must connected the two cute antennas you found in the box if you want to get proper RF transmission.

THE REAR PANEL

① Audio Output XLR: to connect a balanced cable with XLR connector (we forgot to tell you that although your MOD-800 system is wireless, you still need to connect the receiver to your Mixing Desk and to a wall plug!)

4. Operation

OK, if so far you remember all the functions and features of your MOD-800 system you are ready to operate the Unit. Let's start from the Receiver:

4.1 For the MOD-800R, PLL UHF Diversity Receiver

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.MUTE: If the Display shows ▲LTO, the Mute function is disengaged. If the display shows MUTE, the Mute function is engaged.

D. This shows the selected frequency.

E. This shows you the remaining life of the Battery of your Transmitter. 3 segments means full life, 1 segment means it is time to replace or recharge the battery. Cute, isn't it? If this icon disappeared, it means that your transmitter is switch OFF.

F.This bar indicates the level of the audio signal coming into the Receiver.

G. This bar indicates the level of radio signal coming into the Receiver.

H. This indicates which of the 2 antennas is operating. Radio signal will automatically switch from Ant 1 to Ant 2 indicating that the diversity circuit is operating properly.

- And now, let's see the four keys in detail:

MEM key: The first function of this key is to activate the AUTO-SCAN function. Suppose that you have more than one ▲LTO transmitter in front of you able to operate with your MOD-800R Receiver and you want to start to operate one of them with your MOD-800 Receiver.

First of all you should turn your Transmitter ON. Then, with your MOD-800R Receiver turned ON, press the MEM key for at least one second. Your MOD-800R will automatically look for the frequency where your ▲LTO Transmitter is operating. It will scan all the 12 Groups and Channels for a total of 144 frequencies available.

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 MOD-800R Receiver. Please note that frequencies can be scanned manually using the UP/DOWN key. See the Annex for more details.

MENU key: This key activates several functions:

Press this key slightly once and you will get into the MANUAL SELECT for the 144 frequencies. When the GROUP indicator is flashing you can press the UP/DOWN keys to select manually the desired Group. Then, you can press the MEM key to store this setting.

Press the MENU key twice and the CHANNEL indicator will flash. Use the UP/DOWN keys to selected the desired channel and then press MEM key to store this setting.

Press the MENU key three times and you can adjust the OUTPUT LEVEL. Using the UP/DOWN keys you have the choice to select three different levels:

PL 0 indicates that the output level is 1.1mV PL 1 indicates that the output level is 575mV PL 2 indicates that the output level is 250mV

Fig 1

Note: This function is only available using the XLR balanced output.

Press the MENU key four times and you will get into the MUTE function. Use the UP/DOWN keys to mute/unmute the Unit. When the display shows ▲LTO the unit is unmuted. When the display shows MUTE, the unit is muted.

Fig 3 mute function on

Press the MENU key five times and you will activate the SQUELCH function. To squelch or not to squelch, this is the issue...

Squelch is a complicated name to express a simple concept: The threshold above or below that a signal is made pass through the receiver or not.

No.	squelch threshold
1	95.0dB
2	91.7dB
3	88.3dB
4	85.0dB
5	81.7dB
6	78.3dB
7	75.0dB
8	71.7dB
9	68.3dB
10	65.0dB

4.2 For the MOD-800H/800P transmitters

Press the CH/ON key for a few seconds and the transmitter will be powered ON. At this point the blue back lighted display will show:

• The frequency at which the unit is operating
• The Battery Status

Fig 5

And now that you know how to operate your MOD-800R Receiver, let's learn how to use the MOD-800 Transmitters. The following instructions apply both to the handheld version and to the bodypack version.

There are 2 keys on the Transmitter labelled CH/ON and SELECT.

With the Transmitter switch ON you can slightly press the CH/ON key again and you will access to the following parameters:

• Preset Group
  

Fig 6

• Preset Channel
  

Fig 7

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. 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.

In your Transmitter there are 12 frequency bands or GROUPS. Each Group contain 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 MOD-800R Receiver. In this way the Receiver with synchronize automatically on the Transmitter frequency.

- RF Output Power Select

Your Transmitter can operate on three different levels of output power. These are different from the Handheld Model and the Bodypack model.

For the Handheld model the levels are

• PL O, the output power is 5dBm;
• PL 1, the output power is 10dBm;
• PL 2, the output power is 15dBm;

and for the Bodypack version the levels are

• PL 0, the output power is 3dBm;
• PL 1, the output power is 5dBm;
• PL 2, the output power is 12dBm;

- 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. Your choice of setting will automatically be saved into the Transmitter in a few seconds. The blue display shows "lock" and "unlock" depending on the operating mode.

Fig 10: LOCK

Fig 11: UNLOCK

- Mute Function

Sometimes, there are things that you want to tell to your Friends on stage or your nearby Companion during a Meeting but not necessarily to the rest of the world especially if you are ON LIVE on CNN... A smart feature on your Transmitter allows you to easily MUTE the microphone so you are free to talk to the people next to you without the rest of the world hearing what you say. To enter into MUTE function simply press the SELECT key for a few seconds and the Transmitter will mute any audio signal going to the Receiver. Press SELECT again for a few seconds and you will UNMUTE the Transmitter.

5. Modelling Technology for Wireless Microphones.

This document applies to all ▲LTO Wireless Receivers used in conjunction with ▲LTO Handheld and Bodypack Transmitters

Fundamentals: ▲LTO has created and integrated a wireless microphone system offering 16 modelling presets resulting in a range of tonal response for a wide variety of applications. Until this innovative introduction made for the first time in the world in a wireless system by ▲LTO, wireless systems consisting of receiver and microphone transmitters produced a single sound pattern. Each microphone capsule design, because of the laws of physics, features its own frequency response and adds a certain tonal colour to the signal it transmits. If you do not like the colour added, you must change the microphone section of your transmitter, much like a painter chooses a different colour from his palate. Many brands today offer several different microphone capsules for their wireless systems but this flexibility is far behind the wide choice of tones or "models", as we call them at ▲LTO. In fact, a specific model of wireless microphone may be used by a male vocalist or female vocalist during a live performance, by a Priest in a church service, by a speaker during a seminar, by and aerobics teacher during a training lesson, by a DJ, by a choir, by an announcer, by an auction director, we could go on and on forever with endless applications.

It is now evident that each one of these users would benefit from a different tone or "model". But even the same user would like to get a different voicing or "model" depending on the style he is singing. What model serves the music best? It's fair to say that it will be different whether he's singing Rock, Blues, or Folk and, of course can also change from song to song. It is unlikely to buy several different microphone capsules in order to get different tone or "model" depending of the kind of use of performance. This would be unpractical, since it would be impossible to change a microphone capsule during a performance, not to mention the cost involved.

▲LTO has therefore created and integrated in some of its wireless receivers a range of MODELS. Using these 16 different MODELS the user can select different sound patterns simply with the turn of one knob. There are preset MODELS for male and female Vocalists, DJ, Speakers, Announcers, and more. In a few words, with the ▲LTO modelling technology applied to wireless systems, the User can "fine tune" the sound of his microphone in 16 different ways.

Here is a List and description of the MODELS available on the ▲LTO Receivers:

MODEL 1: FLAT- In this position the Modeller is in bypass mode. The ▲LTO Modeller is not adding any character to the Audio Output

MODEL 2: CONFERENCE- To be used during Meetings. Especially made for speech and to avoid the typical boominess of many wireless microphones used for such purpose.

MODEL 3: BROADCAST- This Model will add a certain character to the signal. It is typical of the Male Announcers through a solid state Transmitter.

MODEL 4: WARMTH- Good for Lead Vocalist Male and Female. It will make the Male voice warmer and the Female voice more body.

MODEL 5: DE-ESSER- The name tells everything. Use it to de-emphasize the sibilants, like the letter sound 's', for example, from your vocals.

MODEL 6: VINTAGE RADIO- Old tube based Receivers made the Announcer voice sound like... yeah, we call it Vintage. Try it for a smooth satin voice. Ideally used for speech, but we found some other neat applications in the studio as well!

MODEL 7: MID-WARMTH, a moderate voice enhancement making use of Bass enhancer.

MODEL 8: GROOVY- to add a touch of groove to Male and Female Lead Vocalist. Perfect for Blues.

MODEL 9: SHARP- makes human voice quite crispy. Perfect for voice poor in high frequencies or if you get a cold...

MODEL 10: KARAOKE- yes, microphones are used in a very peculiar way in Karaoke Bars and Venues. Usually the sound systems there are poor. Use this Model to add high frequencies and have your voice sound like a Pro's!

MODEL 11: PIANO BAR- it similar to the Karaoke Model but we have also added key low frequencies to give the voice more body.

MODEL 12: HEAVY METAL- This model will make your voice sound very aggressive. Good for Rock & Roll and if you have an argument with your Mother in law...

MODEL 13: DISCO- It is similar to the Heavy Metal model but more tailored for Disco Music.

MODEL 14: CHOIR- Selected frequencies have been manipulated to make this Model suitable for more than one vocalist when singing in a choir

MODEL 15: FEMALE VOICE- Female Singers voices present a frequency response that is quite different from the Male voice. This Model gently adds certain low frequencies to make the female voice more consistent and at the same time will make the highest frequencies of the female voice more sparkling and defined.

MODEL 16: PIANO BAR CHOIR- It is a combination of the Karaoke Model and the Piano Bar Model. Good when more than one voice is singing along together.

7. 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, MOD-800R Wireless receivers are available in a number of models, each with a unique frequency range. Each frequency range, or band, spans up to 24MHz of the wireless broadcast spectrum. Available bands are:
