The IMG STAGELINE STA-800D is a stereo Class D PA amplifier, representing a new generation of high-efficiency, high-power, and lightweight amplification for both fixed installations and mobile applications.
High Power & Efficiency (Class D): Utilizes a Class D concept with power amplifier modules from HYPEX for high energy efficiency and reduced heat generation.
Stereo Output: Delivers robust power in stereo mode:
2 x 400 W RMS at 4 Ω
2 x 210 W RMS at 8 Ω
Peak output power of 1,000 W.
Silent Operation: Features temperature-controlled fans for quiet operation, suitable for noise-sensitive environments.
High Power Reserves: Designed with a compact switch-mode power supply and large buffer capacitors for powerful bass reproduction and high power reserves.
Audio Fidelity: Achieves excellent audio specifications with a wide frequency range (20–20,000 Hz), high S/N ratio (> 110 dB(A)), and extremely low total harmonic distortion (THD < 0.004%).
Compact and Lightweight: Features a super slimline design (1 Rack Unit) and a low weight of only 4 kg, ideal for easy transportation and rack mounting.
Professional Connections: Equipped with NEUTRIK SPEAKON connections, balanced XLR inputs, and unbalanced RCA inputs.
Protection: Protected against short circuit and overtemperature.
