Description

The 4-Channel 500W Pema Network Power Amplifier from Ashly consists of eight inputs and four power amplifier outputs with the ability to assign any input to any output. The amplifier features pre-installed OPDante network audio interface card and the Protea DSP Software Suite. When switched into bridged-mono mode, four powered outputs deliver 125W into a 70V load and channel pairs can be bridged for 250W into a 140V load. The power amplifier includes Euroblock input connectors and Euroblock output connectors. Besides remote standby for power up, DC remote level control, and contact closure preset recall, the amplifier also features Ethernet control, level, mute, polarity, temperature, current, and amplifier over current conditions. The front panel indicates power status, standby, protect, power switch On/Off, signal level, bridge, temperature & current levels, and Ethernet communication. A temperature dependent speed-controlled axial fan shall maintain the correct operating temperature. Full programming and control of the unit is from the rear panel RJ-45 jack connected to a 10/100BASE-T Ethernet LAN connected to a PC running the Protea Software. The amplifier mounts in a standard 19” rack using two spaces (3.5” high). The power amplifier has an internal factory-installed Digital Signal Processing (DSP) controlled using the Protea Software Suite (network-enabled). Each amplifier input channel can be configured with pluggable DSP blocks to have its own dynamics control, gain functions, graphic and/or parametric EQ, Hi-pass/Lo-pass filters, time delay, metering, and test signal generator. Hot-plug DSP placement allows you to insert any function into any channel block, even when running live audio. A mixer section with assignable routing allows any input to drive any or all amplifier outputs. The matrix mixer also has selectable gain sharing automatic mixing capability. Outputs have the same DSP functions as inputs, with the addition of a quick and automated crossover setup. Up to 30 presets shall be standard and four presets shall be accessible via contact closure using the Protea Software Suite. Read more

About the Ashly PEMA 4125.70D 4-Channel Network Power Amplifier plus OPDante Option Card, 125W at 70V, 8x8 DSP Matrix, CobraNet

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.
