Description

The ADA 12K4 Touring Rack is a pre-configured 12-channel system rack for touring and live sound. It houses three ADA 12K4 power amplifiers with DSP & DANTE™. Each amp delivers 4 × 2700 W @ 4 Ω, providing up to 32.4 kW total system power. 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. Everything is built into a 12U shockmount rack with two slide-in doors for protected transport and fast access on site.

The 3U ADA TPP patch panel with clear, tour-proof labelling and premium Neutrik® connectors gives direct access to the three amplifiers at the front:

Loudspeaker outputs: 3 × SpeakON NL8, 12 × SpeakON NL4
Inputs: 12 × XLR analogue, 4 × AES3 digital
Link: 6 × AES72 RJ-45 for AoC routing
Network: 2 × Ethernet RJ-45 (Dante™)

The 12 × 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.

The built-in 2U 32A three-phase power distribution unit with daisy-chain provides centralised power management. It offers six Schuko outlets: three supply the amplifiers and three remain available for additional devices. Three circuit breakers and three digital voltage/current meters support protected operation and quick on-site checks.

A 1U LED rack light with motion sensor and multicolour-led completes the rack for easy cabling even in dark environments.
