D LINE 4000

D LINE 4000

Step up to the D LINE 4000, a relentlessly capable two-channel amplifier from the esteemed D LINE series, forged to operate as the high-performance backbone of modern live sound rigs and premium fixed installations. Utilizing advanced Class 1™ output circuitry, this model strikes a perfect equilibrium between aggressive power delivery and sustained thermal composure. It is precisely engineered for audio professionals and installers who require a heavy-duty, dependable engine to drive mid-sized line arrays, high-output point-source enclosures, and formidable sub-bass systems with absolute confidence.

Engineered for undisputed authority across multiple load configurations, the D LINE 4000 pushes a commanding 850 watts per channel at 8 ohms, expanding to 1350 watts at 4 ohms, and a robust 1850 watts per channel at a punishing 2 ohms in stereo mode. Should you need to consolidate its force, bridging the amplifier yields a massive 2800 watts into 8 ohms and an immense 3600 watts into 4-ohm loads. Backed by a high-speed slew rate greater than 10V/us, it delivers exceptional transient response to cleanly capture explosive percussive attacks. A damping factor exceeding 300 guarantees relentless grip over low-frequency drivers, translating to immense dynamic headroom and distinctly tight, chest-thumping bass response.

Seamless integration into complex audio ecosystems is achieved through the D LINE 4000's highly flexible input and control architecture. Engineers can effortlessly match system processors or consoles via the multi-stage input sensitivity selector, featuring standard 0.775V, 1 V, and 32 dB thresholds. The precision input stage is designed for optimal signal transfer, offering a balanced input impedance of 20k ohms alongside 10k ohms unbalanced. Superior stereo imaging and channel isolation are strictly maintained thanks to a crosstalk rating of over 65dB, ensuring that complex dual-zone or stereo routing remains completely independent and free of signal degradation.

The sonic integrity of the D LINE 4000 is defined by its pristine acoustic fidelity, characterized by a ruler-flat frequency response from 20Hz to 20kHz (+0/-1.5 dB). It operates with a highly transparent signal path, utilizing a signal-to-noise ratio greater than 90dB to guarantee an imperceptible noise floor during quiet, critical passages. Total Harmonic Distortion plus Noise (THD+N) is strictly regulated below 0.5%, preventing harshness even when the system is pushed to its operational limits. Driven by a precise voltage gain of 40 dB, this unit ensures that every frequency is reproduced with clinical accuracy, rich uncolored tone, and brilliant clarity.

Encased in a road-ready 21 kg chassis, the D LINE 4000 is built to withstand the punishing demands of both rigorous touring schedules and intensive permanent installations. Reliability is guaranteed by an aggressive front-to-rear active cooling tunnel and an exhaustive suite of intelligent protections, deploying soft start, DC, short circuit, overload, thermal, and clip limiting protocols alongside VHF safeguards. Melding tactical build quality with exceptional sonic muscle, the D LINE 4000 is a formidable asset that ensures pristine, uninterrupted audio delivery in the most demanding real-world environments.
