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 24 MHz of the
wireless broadcast spectrum. Available bands are:
Once you are in operation mode, you can access this key to edit certain
parameters. Press this key for a few seconds and the unit will enter in
the MUTE mode. (In this way, you can tell your Bass Player what you
think about the Sound Engineer without anybody knowing that!). Press
it again for a few seconds and you will unmute the unit.
This unit may be powered from one pair of dry or rechargeable batteries,
um3 size AA 1.5V.
With the rechargeable batteries putting inside, use the charger supplied to
recharge the batteries.
Note: This charger is for buyer's option. You can buy it from your dealer.

LTO Receivers:
FLAT- In this position, the Modeller is in bypass mode. The
Modeller is not adding any character to the Audio Output
LTO
CONFERENCE- To be used during Meetings. Especially made for
speech and to avoid the typical boominess of many wireless microphones
used for such purpose.
BROADCAST- This Model will add a certain character to the signal.
It is typical of the Male Announcers through a solid state Transmitter.
WARMTH- Good for Lead Vocalist Male and Female. It will make the
Male voice warmer and the Female voice more body.
DE-ESSER- The name tells everything. Use it to de-emphasize the sibilants,
like the letter sound 's', for example, from your vocals.
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!
This nice blue LCD will indicate the current operation status.
If you press this key for a few seconds, your Transmitter will be switched
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 are in the LOCK position
no further operation is allowed. And in a few seconds, the display will show
the current selected frequency (in MHZ). Battery level will also be shown.
Once you are in operation mode, you can access this key to edit certain

MUTE mode. (In this way, you can tell your Bass Player what you think about
the Sound Engineer without everybody knowing that!). Press it again for a few

MID-WARMTH, a moderate voice enhancement making use of Bass
enhancer.
GROOVY- to add a touch of groov e to Male and Female Lead Vocalist.
Perfect for Blues.
This connector is used to connect the unit with the clip microphones. for
example, HM-38 condenser microphone or LM-10 clip microphone.

PIANO BAR- it similar to the Karaoke Model but we have also added
key low frequencies to give the voice more body.
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...
DISCO- It is similar to the Heavy Metal mod el but more tailored for
Disco Music.
CHOIR- Selected frequencies have been manipulated to make this
Model suitable for more than one vocalist when singing in a choir
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.
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.

ELEMENTS
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:
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 , the Mute function is disengaged. If the
display shows , 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. If this icon disappeared, it means
that your transmitter is switched OFF.
F. This bar(AF) indicates the level of the audio signal coming into the Re ceiver.
G.This bar(RF) 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 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 at least for
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.
5. MODELLING TECHNOLOGY
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 serv es 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 diff erent tone or "model"
depending of the kind of use of performance. This would be unpractical, since
it would be impossible to change a microphone cap sule during a performance,
not to mention the cost involved.
LTO has therefore created and inte grated in some of its wireless receiv ers 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.

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 11: UNLOCK
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.
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:
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.
PL 0 indicates that the output level is 1.1V
PL 1 indicates that the output level is 575mV
PL 2 indicates that the output level is 250mV

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 mainly 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.
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.
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.

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 switching ON, you can slightly press the CH/ON key again
and you will access to the following parameters:
Preset Group
Preset Channel
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 0, the output power is 0 dBm
- PL 1, the output power is 5 dBm
- PL 2, the output power is 10 dBm
And for the Bodypack version the levels are
- PL 0, the output power is 0 dBm
- PL 1, the output power is 5 dBm
- PL 2, the output power is 10 dBm
position the transmitter nearby the receiver.
