IPA 412 T (LD Systems) 4-channel DSP Installation Amplifier 4 x 120 W @ 4 Ohm / 70V/100V

Professional 4-channel installation amplifier
Powerful class-D power amplifier with 4 x 120 W (IPA 412 T) or 4 x 240 W (IPA 424 T) at 4 Ohm (transformer bypass) or 70V/100V outputs through toroidal core transformer
Stereo/parallel/bridge mode selector switch per channel pair
4 balanced line inputs and 4 speaker outputs with terminal block connections
User-friendly front panel with signal, limit, protection, mute and bridge mode LEDs per channel and clipping LEDs for the inputs
Speaker protection circuits: DSP limiter, overcurrent, direct current, overheating, short circuit as well as switchable auto standby mode
DSP presets with HPF and LPF which can be activated via DIP switches
REMOTE audio and control bus based on CAN architecture (Controller Area Network)
Equipped for future LD Systems remote control panels and paging microphones
Slot for future optional expansion cards for Ethernet or Ethernet + Dante
