About the Ashly PEMA 4250.25 Network Power Amplifier 4 x 250W @ 25V with 8x8 Protea DSP
The Ashly PEMA 4250.25 is a fully integrated, network-powered audio matrix amplifier designed as a centralized hub for commercial multi-zone sound systems. This all-in-one unit combines a four-channel power amplifier, an 8x8 digital signal processing matrix, and network control in a single 2U chassis. Each amplifier channel is specifically configured to deliver 250 watts into 25V constant-voltage lines, making it an ideal solution for driving distributed speaker systems in facilities like corporate campuses, transportation hubs, and large retail environments. The integrated 8x8 DSP matrix provides immense flexibility, allowing any of the eight inputs to be routed, mixed, and processed for any of the eight outputs, enabling complex zoning, source management, and acoustic tuning entirely within the unit.
Network connectivity is central to the PEMA 4250.25's design, allowing for complete remote configuration, control, and monitoring via Ethernet. Through Ashly's software, system integrators can set input gains, design the DSP matrix with EQ, dynamics, delay, and crossovers, adjust output levels, and monitor system health. The four amplified outputs drive speaker zones directly, while the additional four processing outputs can be used for feeds to external devices, recording, or as preamp outputs for system expansion. This integrated approach drastically simplifies installation, reduces component count, and provides a software-defined hub for the entire audio system.
Built for reliability in 24/7 operation, the amplifier includes comprehensive protection against faults. Its combination of constant-voltage amplification, a powerful DSP matrix, and networked intelligence in one device makes the Ashly PEMA 4250.25 a highly efficient and scalable solution for integrators who need to deploy a powerful, flexible, and easily manageable audio infrastructure for large-scale, multi-zone applications.
