The IHOS D4004 is a robust 4-channel power amplifier built for demanding professional audio environments. It delivers 4 x 900 W into 8 ohms or 4 x 1800 W into 4 ohms, providing generous headroom and confident control for installations and live events. Rear-panel trim pots allow precise per-channel level matching and zoning, reducing reliance on external processing. Balanced XLR inputs with 20 kOhm impedance and switchable 0.77 V / 1.44 V sensitivity ensure seamless integration with a wide range of mixers and system controllers. Loudspeaker connections are handled via secure 2- and 4-pole Speakon outputs for reliable touring and install use.
Engineered for clarity and authority, the D4004 achieves a signal-to-noise ratio over 112 dB, a damping factor above 1000 at 8 ohms, and total harmonic distortion under 0.1% from 20 Hz to 20 kHz at 1 W. A variable-speed fan with front-to-rear airflow supports dependable rack cooling, while front-panel level controls enable swift, confident adjustments. Ideal for multi-zone installations, stage monitoring, and medium-to-large PA systems, the D4004 delivers powerful, consistent performance where reliability and sonic detail are essential.
