CAUTION
Never remove the cover – there is a risk of electrical shock. The device does not contain any parts
inside requiring repair or servicing by the operator. Only allow qualified service technicians to carry out
maintenance and repairs.
To prevent electrical shock, do not touch exposed speaker cables/wires while the amplifier is in operation!
CLASS 2
WIRING
High output voltage; risk of electrical shock! A trained person must install the wiring for the loudspeaker connection terminals using
prefabricated wiring systems!
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 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)

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.
