JAFour 4-Channel Class-D Amplifier Clean Power, Versatile Control, Compact Form The JAFour is a powerhouse in a sleek chassis, delivering clean Class-D efficiency and 4-channel flexibility. Whether you’re powering a full system or bridging channels for higher output, this amplifier provides precise control and strong, reliable performance. It supports both high-level (speaker wire) and low-level (RCA) inputs, making it compatible with virtually any audio setup. With selectable high-pass, low-pass, and full-range crossovers plus variable bass boost, you can customize your system’s sound to match your music—or your mood. Why it’s robust Real power you can use: 125W x4 @ 4Ω, 215W x4 @ 2Ω, or 445W x2 bridged @ 4Ω (1% THD+N). Strong dynamic headroom: Up to 950W max dynamic power (10% THD+N). Precision tuning: Selectable HPF/LPF with wide 50–250 Hz range, plus variable bass boost @ 45 Hz (0–6 dB). Clean signal path: 82 dBA S/N (1 W ref) and <0.12% THD+N at 1 W for smooth, low-noise performance. Flexible integration: Works with high-level and RCA inputs; 2/4-ohm stereo stable; bridgeable for powerful sub setups. Installer friendly: Variable gain (300 mV–6 V), 8 AWG power/ground and 12 AWG speaker wire recommendations, 30A fuse, and a compact 1.99” x 6.53” x 9.13” (H x D x W) footprint.
