Power Amplifiers XPA U 358

The Extron XPA U 358 is a high-power audio amplifier that meets ENERGY STAR certification, offering eight channels with 35W per channel in a compact half-rack, 1U design. Thanks to its fanless convection cooling system, the device can be stacked without leaving space for heat dissipation, optimizing rack space efficiency.

Using CDRS™ (Class D Ripple Suppression) technology, the XPA U 358 ensures smooth audio quality, reduces RF interference, and optimizes operational efficiency. It also features InstaWake™ mode, enabling fast startup in under 100ms while saving power by automatically switching to standby mode after 25 minutes of inactivity.

Key Features:

• 35W per channel at 8Ω, 4Ω, or 70V/100V.
• Compact half-rack, 1U design, saving space.
• Fanless convection cooling, allowing multiple units to be stacked without ventilation gaps.
• CDRS™ technology (Class D Ripple Suppression) enhances audio quality and reduces RF interference.
• High efficiency up to 77%, reducing power consumption and operating costs.
• InstaWake™ mode, fast startup in under 100ms when signal is detected.
• Auto-standby mode after 25 minutes of inactivity to save energy.
• Multiple protection layers: Short circuit, overheat, and DC fault protection for amplifier and speaker safety.
• Remote control support via standby port.
• ENERGY STAR certified, ensuring low power consumption.
• Extron Everlast™ power supply for high reliability.
