4. INSTALLATION & CONNECTION
4.1 Power Up and Audio Connections
a. Audio Connections
The connections between the LTO DRIVE3.4 and the other audio devices have to be made using high quality
cables so to prevent bad performances of the LTO DRIVE3.4 itself. So it should be good to use low-capacitance
shielded cables with a flexible internal conductor. Connect the cables to the LTO DRIVE3.4 properly by observing the following precautions:
Do not bundle audio cables with AC power cords.
Do not place audio cables and LTO DRIVE3.4 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 LTO DRIVE3.4'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 LTO DRIVE3.4 and plug the power cord
into an AC outlet.
Turn on the power of the LTO DRIVE3.4, pushing the ON/OFF button on the front panel.
Turn on the power of the amplifier/mixer, and adjust the volume.

Warnings:
1. Before starting a MIDI session please set on the ALTO DRIVE3.4 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 ALTO DRIVE3.4 it's advisable to run a manual STORE to save preset changes done by means
of the external controller. After saving, reboot the ALTO DRIVE3.4 to use it as a stand-along unit.
4. When setting and resetting mutes (controller 23) by MIDI, the relative LEDs are NOT actived.
