Description

The ADA 12K4 SINGLE RACK is a pre-configured 4-channel amplifier rack featuring one ADA 12K4 power amplifier with DSP and Dante™, delivering 4 × 2700 W @ 4 Ω. High-resolution processing (24-bit / 96 kHz with 32-bit floating point and FIR/IIR/raised-cosine filters) supports modern system optimisation, including EQ, crossover and delay.

The 2U ADA SPP patch panel with clear labelling and premium Neutrik® connectors gives direct access to amplifier:

Loudspeaker outputs: 1 × SpeakON NL8 + 4 × SpeakON NL4
Inputs: 4 × XLR analogue + 4 × AES3 XLR digital
Link: 4 × analogue via 2 × RJ-45 ports for Audio over Cat (AoC)
Network: 2 × Ethernet RJ-45 ports (Dante™)

The 4 × XLR analogue signals can be linked via the AES72 RJ-45 ports using additional Audio over Cat (AoC) adapters. Two Dante™ ports with support fast network and Armonía Pro Audio Suite™ integration.

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

Everything is built into a 4U shockmount rack with two removable doors for protected transport and fast access.
