Installation And Connection - LD Systems LDDJ300 Manuel D'utilisation

PREVENTIVE MEASURES:
DANGER AT THE SPEAKER OUTPUT!
Power amplifiers are capable of producing dangerously high voltages at the output. To avoid electrical shock,
never touch bare speaker wires or terminal posts while the power amplifier is in operation.

INSTALLATION AND CONNECTION

For trouble-free operation, during setup and rack installation, make certain that the air intake and ventilation of
the power amplifier is not hampered (ventilation slits on the front panel, fan on the rear panel).
We recommend the use of high-quality balanced cables(with two conductors for the audio signal plus separate
shielding mesh) with XLR-type connectors for connecting the signal source (e.g., mixing desk) to the power
amplifier. While it is also possible to connect unbalanced cables to the power amplifier inputs, for reasons of
interference immunity, using balanced cables is always preferable.
In order to reduce power losses, speakers should always be connected using twinaxial speaker cable with a
sufficiently large cross-section.
