The Ashly PEMA 4125.70 is a fully integrated, network-powered audio matrix amplifier designed for sophisticated multi-zone commercial 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 125 watts into 70V constant-voltage lines, making it an ideal solution for driving extensive distributed speaker systems in venues like shopping malls, airports, hotels, and campuses. 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 a cornerstone of the PEMA 4125.70'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 can drive speaker zones directly, while the additional four processing outputs can be used for feeds to external devices, recording, or as preamp outputs for expanding the system. This integrated approach drastically simplifies installation, reduces component count, and provides a centralized, 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 4125.70 a highly efficient and scalable solution. It is designed for integrators who need to deploy a powerful, flexible, and easily manageable audio infrastructure for large-scale, multi-zone applications, eliminating the need for separate amplifiers, DSP units, and routers.
