The Hoellstern Delta 12.4 is a high-performance 4‑channel power amplifier engineered for demanding professional audio. With Hoellstern’s ZeroLatency analogue signal path, it delivers a true 0.000 ms input‑to‑output delay, ideal for time‑critical applications and purist system designs. Remarkably load‑stable down to 1.6 ohms, it maintains control and current delivery on complex loudspeaker arrays. Efficiency up to 85% allows full output from a standard 16 A mains supply, all within a compact, lightweight 2U chassis. Robust analogue protection circuits safeguard against short circuit, DC, over‑temperature, plus HF and LF limiting to protect both the amplifier and connected loudspeakers.
Connectivity and configuration are straightforward: 4 balanced XLR inputs, 4 high‑current Neutrik SpeakON NL4 outputs, and a Neutrik PowerCON mains inlet. Rear‑panel hardware switches select operating modes (stereo or bridged for channels 1/2 and 3/4) and set precise gain at 26 dB or 32 dB for optimal alignment with system controllers. Supplied with a matching PowerCON mains cable, this amplifier is ready to integrate into touring racks or fixed installations.
Perfect for touring, rental and installed sound where reliability, headroom and precise system integration are essential.
