For our LTO AUDIO TEAM, music and sound are more than a job...are first of all passion and let us say our
obsession!

We have been designing professional audio products for a long time in cooperation with some of the major brands
in the world in the audio field.

The LTO line presents unparalleled analogue and digital products made by Musicians for Musicians in our R&D
centers in Italy, Netherlands, United Kingdom and Taiwan. The core of our digital audio products is a sophisticated
DSP (Digital Sound Processor) and a large range of state of the art algorithms which have been developed by our
Software Team for the last 7 years.

Because we are convinced you are the most important member of LTO AUDIO TEAM and the one confirming the
quality of our job, we would like to share with you our work and our dreams, paying attention to your suggestions

we will guarantee you also in future the best quality, the best fruits of our continuous researches and the best prices.

Our LTO CONTROL60 is the result of many hours of listening and tests involving common people, area experts,
musicians and technicians.

The result of this effort is a DSP hi-performance equalizer that can be used in applications as musical performances,
installation and sound reinforcement.

Besides we offer to you a number of factory EQ curves that we collected and transformed in presets now available
in our small, efficient and easy to use LTO CONTROL60.

Nothing else to add, but that we would like to thank all the people that made the LTO CONTROL60 a reality available
to our customers, and thank our designers and all the LTO staff, people who make possible the realization of products
containing our idea of music and sound and are ready to support you, our customers, in the best way, conscious

1. INTRODUCTION

Purchasing LTO CONTROL60, you purchase a very powerful equalizer, easy to use and contain in very efficienta
single unit rack package.
Our new CONTROL60 is a versatile and very powerful parametric/graphic PRE-EQ. It is based on 2 extremely
powerful high speed 24 32-bit DSPs and very high quality 20-bit A/D and 24-bit D/A converters, thepreserving
pureness of analogue sound in your digital applications. It can be operated in 6 different modes:

Graphic 2 30 Dual Mono 1/3 oct(GR.D.M)
Graphic 2 30 Stereo 1/3 oct(GR.ST)
Graphic 1 60 Mono 1/6 oct(GR.Mono )
Parametric 2 30 Dual Mono(PAR.D.M)
Parametric 2 30 Stereo (PAR.ST)

Parametric 1 60 Mono (PAR.Mono)
allowing the user to obtain the desired sound and timbre out of the musical signals easily.
These algorithms are fully dual mono/stereo algorithms and use very powerful high precision and symmetrical
filters, designed for professional use, able to modify the sound color improving the over sound quality withoutall
introducing any loss or distortion.

3.2 The Rear Panel

Input (19/20)

These are XLR balanced connectors which connect to sources such as the channel inserts of mixing consoles.
They may be used with nominal input levels from consumer to professional audio.

Outputs (21/22)

These are XLR balanced connectors which connect to devices such as the channel inserts on a mixing console
or power amplifier input. For mono applications, use the output1 and/or output2.

MIDI Connectors

MIDI in (23): 5-poles DIN connector for the MIDI input to the CONTROL60.
MIDI thru (24): 5-poles DIN connector for the MIDI thru.
MIDI out (25): 5-poles DIN connector for the MIDI output from the CONTROL60.

Power Connector (26)

This is an IEC 3-pole socket for connecting the AC power supply to the CONTROL60.

4. INSTALLATION & CONNECTION

4.1 Power Up and Audio Connections

a. Audio Connections

b. Power Up Setting

The connections between the CONTROL60 and the other audio devices have to be made using high quality
cables so to prevent bad performances of the CONTROL60 itself. So it should be good to use low-capacitance
shielded cables with a flexible internal conductor. Connect the cables to the CONTROL60 properly by observing
the following precautions:

Do not bundle audio cables with AC power cords.
Do not place audio cables and CONTROL60 near sources of electromagnetic interference such as:

Transformers, monitors, computers, etc.
Always unplug cables by firmly grasping the body of the plug and pulling directly outward.
Do not place cables where they can be stepped on.

Before turning on the CONTROL60's power, check if:

All connections have been made correctly.
The volume controls of the amplifier or mixer are turned down.

Insert the Power plug into the POWER input on the rear panel of the CONTROL60 and plug the power cord into
an AC outlet.
Turn on the power of the CONTROL60, pushing the ON/OFF button on the front panel.
Turn on the power of the amplifier/mixer, and adjust the volume.
