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 75W into an 8 ohm load, 125W into an 4 ohm load, and channel pairs can be bridged for 250W into an 8 ohm 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 4125D 4-Channel Power Amplifier plus OPDante Option Card, 125W at 4 Ohms, 8x8 DSP Matrix, CobraNet

The Ashly PEMA4125 is a fully integrated, four-channel powered audio matrix processor designed to simplify and consolidate system design for commercial multi-zone installations. This all-in-one unit combines a four-channel power amplifier with an 8x8 digital signal processing matrix in a single 2U chassis. Each amplifier channel delivers 125 watts into a 4-ohm load, providing reliable power for distributed loudspeaker zones. The integrated 8x8 DSP matrix is the core of the system, offering flexible routing and comprehensive processing—including parametric EQ, dynamics, delay, and crossover filters—on all eight inputs and eight outputs, enabling complex audio distribution and tuning without the need for any external equipment.

This processor simplifies installation by combining multiple system components. The eight inputs can accommodate various microphones and line-level sources, with mixing and routing handled internally. The four amplifier outputs drive zones directly, while the additional four processing outputs can be used for feeds to external amplifiers, recording, or other destinations. Control and configuration are managed through a front-panel interface or optional PC software, enabling the creation and recall of presets for different times of day or event types. This integrated approach reduces rack space, wiring complexity, and potential points of failure.

Built for reliability in continuous operation, the PEMA4125 includes protection against faults such as short circuits and thermal overload. Its combination of amplification, a flexible DSP matrix, and mixing in one device makes it an efficient and cost-effective solution for integrators designing sophisticated background music, paging, and multi-zone audio systems for restaurants, retail stores, schools, and corporate facilities. It provides a centralized, software-controllable hub for comprehensive audio management.
