Product Overview
Thanks to LD Systems' IPA424T can have a permanently installed audio system with the flexibility you need today and adaptability you'll appreciate tomorrow. The 240-watt Class-D amplifier supports operation at low impedance (4Ω) and on 70/100V distributed lines for maximum flexibility in original and retrofit installations. Integrated DSP functions, such as a parametric EQ with matching speaker library and dynamic tools, provide users with unparalleled control over their soundscape. Ease of use is at the core of the IPA series design. A user-friendly front panel displays at-a-glance LED verification of signal, limit, protection, mute, and bridge mode status for each channel as well as clipping on the inputs. The unit's internal DSP also features a parametric EQ and DIP switch selectable preset high-pass/low-pass configurations. Looking to the future, you'll see the IPA424T is equipped for integration with LD Systems' upcoming remote control panels and paging microphones (sold separately). You'll find priority source selection and delay as available options allowing you to adapt to variances in room size and attendance numbers as well as safety and security requirements. Plus there's an expansion slot just waiting for optional Ethernet, or Ethernet + Dante cards (sold separately). With scalability and future-proof design, the IPA424T offers the quality and peace of mind installers and end users demand.
