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.
