1. INTRODUCTION
Thank you very much for expressing your confidence in LTO products by purchasing our LTODRIVE3.4 .
With the LTODRIVE3.4 you have acquired an extremely musical and flexible Active Crossover which will
provide you also the subwoofer application.
Our new LTODRIVE 3.4(2 inputs , 6outputs , matrix-like operation X-over) allows the user to work with the
quality of the 2/3 by 24 32-bit DSPs, permits extremely precise and fast speakers control and equalization for
PA systems with the power of a matrix process allowing each kind of combination in assigning the 2 inputs
to the 6 outputs. The LTODRIVE 3.4is based on2/3 extremely powerful , high-speed 24 32-bit DSP and
very high quality 20-bit A/D and 24-bit D/A converters, preserving the pureness of analogue sound in your
digital applications. The 128 64 graphical display and the 14 buttons and the relative encoder available on
the front panel, offer an easy way of editing data, so to create new custom powerful and exciting presets
which may then be stored in the unit as user's presets . The integrated MIDI interface permits real-time editing
with a powerful pc based SW or a MIDI standard sequencer.
Both input channels feature a digital , high quality filters 5-band parametric equalizer, allowing boost/attenuation
of 15 dB in 0.5dB increment's steps. On each output channel is possible to have a 4th order low pass and a
high pass filters, limiter /compressor and polarity switchable 0 or 180
.

Inputs(14)
These are XLR balanced connectors which connect to sources such as the channel inserts on mixing
consoles. They may be used with nominal input levels from consumer to professional audio.
Outputs(15)
LTODRIVE3.4 has 6 outputs, they are XLR balanced connectors which connect to devices such as
the channel inserts on mixing console or power amplifier inputs .
MIDI Connectors(16)
-MIDI in: 5-poles DIN connector for the MIDI input to the LTODRIVE3.4.
-MIDI thr: 5-poles DIN connector for the MIDI thr.
-MIDI out: 5-poles DIN connector for the MIDI output from the LTODRIVE3.4.
Power Connector(17)
This is an IEC 3-pole socket for connecting the AC power supply to the LTODRIVE3.4.
4. INSTALLATION & CONNECTION
4.1.Power Up and Audio Connections
a. Audio Connections
The connections between the LTODRIVE3.4 and the other audio devices have to be made using high
quality cables so to prevent bad performances of the LTODRIVE3.4 itself. So it should be good to use
low-capacitance shielded cables with a flexible internal conductor. Connect the cables to the LTODRIVE3.4
properly by observing the following precautions:
Do not bundle audio cables with AC power cords.
Do not place audio cables and LTODRIVE3.4 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.
Avoid twisting a cable or having it make sharp, right angle turns.
b. Power Up Setting
Before turning on the LTODRIVE3.4'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 LTODRIVE3.4 and plug the power cable
into an AC outlet.
Turn on the power of the LTODRIVE3.4, pushing the ON/OFF button on the front panel.
Turn on the power of the amplifier/mixer, and adjust the volume.

restore complete access to all the system functions, it is sufficient to change the PASSWORD field
again to match the other field.
If the two fields aren't matched, the NEW PASSWORD field results blank, in order to protect the system
password; when the two fields are matched, the NEW PASSWORD content becomes visible and therefore
may be changed, allowing to change the system password; to change a password, select the character
string, use Left/Right keys to select a character and change the character using the dial. The default
password when the LTODRIVE3.4 is shipped is 000000 (all zeros).
Never forget the system password!
If you forget the system password you will be unable to unlock your LTODRIVE3.4; a lost password
Is unrecoverable. Consult your LTO dealer in order to restore and unlock the system.

Note:
Select the channel to edit by means of the controller 22 (Mode channel).
Warnings:
1. Before starting a MIDI session please set on the ALTODRIVE3.4 the same MIDI channel used by the
external controller.
2. During a MIDI control session the unit's graphic display is NOT updated.
14
3. After MIDI use of ALTODRIVE3.4 it's advisable to run a manual STORE to save preset changes done by
means of the external controller. After saving, reboot the ALTODRIVE3.4 to use it as a stand-along unit.
4. When setting and resetting mutes (controller 23) by MIDI, the relative LEDs are NOT actived.
