Introduction - LD Systems LDIPA412T Manuel D'utilisation

To prevent electrical shock, do not touch exposed speaker cables/wires while the amplifier is in operation!
High output voltage; risk of electrical shock! A trained person must install the wiring for the loudspeaker connection terminals using
prefabricated wiring systems!
CLASS 2
WIRING
Warning! This symbol indicates hot surfaces. Specific housing parts can become hot during operation. Allow the device to cool for at least ten
minutes after use. Only then can it be transported or touched.
Warning! This device is designed for use up to a maximum height of 6,562 feet above sea level.
Warning! This device is not intended for use in tropical climates.
Protective earth (ground)
To identify any terminal which is intended for connection to an external conductor for protection against electric shock in case of a fault, or
the terminal of a protective earth (ground) electrode.
"ON" (power)
To indicate connection to the mains, at least for mains switches or their positions, and all those cases where safety is involved.
"OFF" (power)
To indicate disconnection from the mains, at least for mains switches or their positions, and all those cases where safety is involved.
WARNING: HIGH-VOLUME AUDIO PRODUCTS!
This device is intended for professional use. The commercial operation of this device is subject to applicable national regulations and directives for accident
prevention. As the manufacturer, Adam Hall is legally bound to specifically point out potential health risks. Hearing damage caused by high volumes and
prolonged exposure: Using this product can generate high sound pressure levels (SPL), which can cause irreparable hearing damage to artists, employees,
and audiences. Avoid prolonged exposure to high volumes above 90 dB.

INTRODUCTION

IPA 424 T and IPA 412 T are DSP-based 4-channel installation amplifiers in 19" rack format specially developed for professional audio installations. They have
integrated transformers per channel and offer connections for 100 V/70 V and Low-Z systems up to 4 Ohm. For optimal energy efficiency, the devices have
auto standby switches. A slot for optional expansion cards enables the IPA amplifier, including all internal DSP parameters to be controlled via Ethernet
and, thanks to the Dante AoIP connectivity, to be integrated into larger installation networks. The IPA series can also interact with remote units and paging
microphones from LD Systems via a REMOTE audio and control bus based on a CAN (Controller Area Network) architecture. This combination of powerful
functions makes the IPA series the best choice for permanent installation.
