With the LTODRIVE2.3 you have acquired an extremely musical and flexible Active Crossover which
will provide you also the subwoofer application.
Our new LTODRIVE 2.3(2 inputs , 4outputs , 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 4 outputs. The LTODRIVE 2.3 is based on 2/3 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 12
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 4
order low pass and a high pass filters, limiter /compressor and polarity switchable 0 or 180 .

4. INSTALLATION & CONNECTION
4.1.Power Up and Audio Connections
a. Audio Connections
The connections between the LTODRIVE2.3 and the other audio devices have to be made using high
quality cables so to prevent bad performances of the LTODRIVE2.3 itself. So it should be good to use
low-capacitance shielded cables with a flexible internal conductor. Connect the cables to the LTODRIVE2.3
properly by observing the following precautions:
Do not bundle audio cables with AC power cords.
Do not place audio cables and LTODRIVE2.3 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 LTODRIVE2.3'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 LTODRIVE2.3 and plug the power
cable into an AC outlet.
Turn on the power of the LTODRIVE2.3, pushing the ON/OFF button on the front panel.
Turn on the power of the amplifier/mixer, and adjust the volume.
