LD Systems IPA 412 T

The LD Systems LDIPA 412 T 4-channel DSP power amplifier offers 4 x 120 W at 4 Ohms / 70V or 100V.

The 70V/100V outputs are equipped with high quality toroidal core transformers, whilst the low impedance 4-Ohm outputs are completely transformerless to ensure the highest possible audio quality. Energy efficient Class D design with switchable Auto Standby function.

The versatile DSP functions include, amongst others, a parametric EQ with matching speaker library, dynamic tools, a matrix mixer, priority source selection and delay. Despite this range of functions, the IPA Series power amps are easy to operate.

Front panel LED’s indicate functions such as signal, limit, protection and bridge mode.

HPF/LPF presets can be enabled directly on the device via DIP switches.

The LDIPA 412 T is equipped for remote control using future remote panels and paging microphones from LD Systems. The rear mounted expansion card slot provides future connectivity for Ethernet card / Ethernet+Dante card offering comprehensive configuration and management via software & Dante audio networking capabilities with potential connection to a wide range of Dante-enabled devices.

Also available in a 4 x 240 watts variant (LDIPA 424 T) for larger installations.
