Description
The CADAudio PX3002 Astatic is a professional two-channel Class-D power amplifier designed for commercial installed audio, portable sound systems, houses of worship, educational facilities, and corporate AV applications. Its compact 1U, 19-inch rackmount chassis delivers efficient amplification while conserving valuable rack space. The high-efficiency switch-mode power supply with soft-start supports reliable operation in demanding audio environments.
Designed for flexible system configurations, the PX3002 supports stereo, mono parallel, and bridge operating modes. It delivers 2 × 150W at 8 ohms, 2 × 300W at 4 ohms, and up to 600W in bridged operation at 4 ohms. Selectable input sensitivity, a switchable 75Hz low-cut filter, and an integrated peak limiter help provide controlled performance for compatible loudspeaker systems.
The CADAudio PX3002 includes balanced XLR inputs, XLR loop-through outputs, and three Speakon speaker connections for channel A, channel B, and bridge operation. Intelligent temperature-controlled fan cooling helps manage heat during operation, while comprehensive protection circuitry safeguards against DC faults, overheating, overloads, and short circuits. A ground lift switch also helps address unwanted hum caused by ground loops.
