This 1U Class D amplifier features a compact design with a soft-switching LLC resonant power supply and active PFC technology. It offers 2×300W @ 8Ω and 2×450W @ 4Ω output, with ≤0.02% THD and a 105dB SNR. Equipped with peak limiting, ripple suppression, and comprehensive circuit protection, it ensures stable performance. A temperature-controlled fan provides efficient cooling. The amplifier supports both constant resistance (stereo) and constant voltage (70V) modes with a high-pass filter switch. Operating at 115-230V, it measures 483 × 300 × 45 mm.
