The Quested APD1000-4 is a compact, high-performance 4‑channel Class D power amplifier with integrated DSP, engineered for precise loudspeaker control and rock‑solid reliability. It delivers up to 1000 W per channel into 4 Ω (500 W at 8 Ω, 1400 W at 2.7 Ω, and 1200 W at 2 Ω), providing generous headroom for modern multi‑channel systems. With a flat 20 Hz–20 kHz frequency response (±0.5 dB), low THD (<0.2% across the band) and fixed 32 dB gain, it ensures consistent, transparent results across all channels. Connectivity is comprehensive, featuring four Neutrik 4‑pole Speakon outputs plus four Phoenix backup outputs for flexible installation. A balanced input architecture and advanced limiters underpin dependable performance in critical environments. The robust 2U chassis measures 482 x 88 x 428 mm and weighs 10 kg, with modest current draw of approximately 2.9 A at 240 V when driving 4 Ω loads. Designed to partner seamlessly with Quested loudspeakers yet versatile enough for wider systems, it’s ideal for studios, post suites, installed sound and high‑quality monitoring. A reliable, efficient solution for precise multi‑channel amplification.
