Extron's XPA U 3502 is a high performance ENERGY STAR qualified audio power amplifier delivering two 350 watt channels into 8 ohms or 4 ohms in a half rack, 1U, convection cooled, plenum rated enclosure that includes rack mount hardware. The XPA U 3502 offers the ability to install high power amplification without using rack spaces for ventilation, conserving precious rack space. It features a highly efficient advanced Class D amplifier design with power factor correction, ultra low inrush current, defeatable auto‑standby with fast wake up, and our patented CDRS – Class D Ripple Suppression.
Every circuit in an XPA Ultra power amplifier is designed by our team of dedicated power amplifier engineers, ensuring that every Extron amplifier meets our high standards of excellence. By designing everything in-house, Extron engineers can meticulously optimize every detail for maximum performance, reliability, power efficiency, and reduced heat.
With tested and measured efficiency benchmarks up to 77%, the XPA Ultra uses less electricity to generate the same amount of power. This has the direct benefit of lower electricity costs and less power infrastructure required.
An XPA® Ultra amplifier runs up to 28% cooler, with up to 49% less power wasted as heat, and up to 59% less radiated heat compared to competitive amplifiers. Electronics that run cooler, last longer and don't transfer heat to other gear sharing the same rack. The low radiated heat of the XPA Ultra amplifiers, enabled by our advanced thermal engineering, saves on cooling costs and allows more channels of amplification to be put into fewer rack spaces.
The XPA U 3502 meets ENERGY STAR qualification requirements with an auto standby feature that places the amplifier into standby after 25 minutes of inactivity. When in standby, the XPA U 3502 draws less than one watt of power. It quickly comes out of standby upon detection of signal in under 100 milliseconds, fast enough that the beginning of audio is not cut off. When coming out of standby, the XPA U 3502 draws minimal inrush current, creating no sudden demand on power systems. For applications where the amplifier is required to remain active at all times, the XPA Ultra provides the ability to defeat auto-standby while maintaining ENERGY STAR status.
Product reliability is a high priority at Extron and we go to great lengths to engineer products with industry-leading low failure rates, driven by rigorous testing of everything we ship. From the elimination of short-lived electrolytic capacitors in the signal path, to PCB designs that exclude the use of failure-prone wire harnesses, to accelerated burn-in testing, the XPA U 3502 is engineered by Extron for many years of service.
