④ It shows the level of the incoming audio signal. When "O"AF Display: LED lights up the incoming audio signal is optimized and will not present distortion. If the "+6" LED lights up, the audio signal is overloaded and you will hear distortion. If only the "-12" LED lights up only 10% of the available signal reaches the Receiver. For optimal sound reproduction, please do not exceed the "O" level.

⑤ It shows the level of the incoming radio signal. Optimum reception RF Display: is granted when all the LEDs light up. If no LED lights up, there is minimum or no radio signal coming into the Receiver. If only a few LEDs light up you may still operate the system but it means you are in a poor reception mode due to Antenna positioning, distance in between Receiver and Transmitter.

OK, if so far you remember all the functions and features of your Mod16 System you are ready to operate the Unit. Let's start from the Receiver:

4. Operation

4.1 For the MOD-16PRO, PLL UHF Diversity Receiver

First, turn the Unit ON. With your Transmitter in ON position, check the Channel Number indicated on the Transmitter display. Now, press the UP/DOWN keys until the same value is shown on the double digit display of your MOD-16 Receiver. Once Receiver and Transmitter are synchronized the LED Meters for Audio signal and Radio frequency will light up.

- Audio Output Level

The volume control knob adjusts the amount of audio signal to be sent to the mixing desk through the balanced or unbalanced output sockets on the rear panel. Turn the volume knob clockwise for maximum output and counterclockwise for minimum output volume.

- Squelch Control:

A squelch circuit is responsible to minimize audible noise during operation. Such circuit will mute the Receiver every time the incoming audio signal drops below a certain threshold. You must use the squelch control with maximum care. If the threshold is too high the squelch circuit will not only cut the noise but also mute certain low-level audio signals. Please experiment various threshold levels before Live operation and choose the most appropriate for your event.

4.2 For the MOD-16H/16P transmitters

And now that you know how to operate your Mod16PRO Receiver, let's learn how to use the MOD-16 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.

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 channel at which the unit is operating
• The Battery Status

Preset Channel Remaining battery life

manning battery life

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

• Preset Channel
• RF power level
• Lock/Unlock

In your Transmitter there are 100 frequencies. Each Group according to EMC regulations.

To select a frequency 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 CHANNEL menu. At this point use the SELECT key to change the value from 1 to 99. Your setting will be frequency automatically saved in a few seconds and the display will go back to the main menu showing the operating 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;

PL.20

and for the Bodypack version the levels are

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

PL.20

To select the proper Output Level, please press the CH/ON key three times and you will access the OUTPUT LEVEL Menu. Then press the SELECT key to change the output level from PL 0 to PL 2. IN a few seconds your setting will be automatically stored and the display will show again the operating frequency.

- 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.

NOTE

- Mute Function

Sometimes, there are things that you want to tell to your Friends on stage or your near by Companion during a Meeting but not necessarily to the rest of the world especially if you are 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.

Note: Why Alto Transmitters come with 100 different frequencies? Not because you will need to use 100 different microphones at the same time. It is unlikely that you will use more than 8 systems at the same time so why 100 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 can be to 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.

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 ⬆TO. 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 ⬆TO 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 ⬆TO Receivers:

MODEL 1: FLAT- In this position the Modeller is in bypass mode. The ▲TO 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...

MODEL13: DISCO- It is similar to the Heavy Metal model but more tailored for Disco Music.

MODEL14: 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

7.1 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-16PRO 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.
