formers, 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.

Before turning on the

LTO DRIVE2.3's power, check if:

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

Inputs

Outputs

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.

LTO DRIVE2.3 has 4 outputs, they are XLR balanced connectors which connect to devices such as the channel

inserts on mixing console or power amplifier inputs .

The connections between the

LTO DRIVE2.3 and the other audio devices have to be made using high quality

cables so to prevent bad performances of the

LTO DRIVE2.3 itself. So it should be good to use low-capacitance

shielded cables with a flexible internal conductor. Connect the cables to the

LTO DRIVE2.3 properly by obser-

ving the following precautions:

Do not place audio cables and

LTO DRIVE2.3 near sources of electromagnetic interference such as trans-

Insert the Power plug into the POWER input on the rear panel of the
