ADA 12K4

As a 4-channel amplifier with DSP & DANTE™, the ADA 12K4 offers maximum power, precise sound and maximum reliability for professional touring and installation applications.

With 4 × 2700 W @ 4 Ω, a 24-bit/96 kHz DSP with 32-bit floating point and FIR, IIR and raised-cosine filters, it delivers outstanding audio quality and enables flexible sound processing. Thanks to two Dante™ ports with integrated switch and Armonía Pro Audio Suite™ integration, the amplifier can be seamlessly integrated into networks.

Armonía Plus allows LD Systems speaker presets to be managed and updated on the DSP amplifier without the need for complex configurations. Alternatively, individual presets can be created and managed to optimise the system for specific requirements.

Versatile connection options with 4 analogue and 4 AES3 inputs as well as 4 analogue, 4 SpeakON and 4 AES3 outputs ensure maximum flexibility. The automatic input backup strategy guarantees uninterrupted operation.

The 4.3-inch touch display with rotary-push encoder and virtual metre bridge for monitoring the available headroom ensures intuitive operation. Flexible routing and mixing options enable customised signal routing for individual applications. Comprehensive limiters (peak, RMS, current, TruePower™) and Active DampingControl™ offer reliable system protection. In addition, together with HealthPlus monitoring in Armonía Plus, the LiveImpedance™ function offers comprehensive and detailed system monitoring.

The protection system against direct current, overvoltage/undervoltage, short circuits and overheating ensure maximum operational safety, bolstered by signal protection mechanisms such as clipping, VHF and long-term RMS protection. Thanks to an energy-efficient mains adapter with Power Factor Correction (PFC) and intelligent rail management, the amplifier is particularly efficient and reliable, making it ideal for professional use.
