Description

Ashly Audio's promise to "Simplify Integration" continues with Pêma (Protea Equipped Media Amplifier), a unique powered processor. Pêma sets a new industry benchmark for value-engineered zone sound systems. By seamlessly merging Ashly's powerful, open-architecture DSP functionality with Ashly's renowned amplifier performance inside a two-rack space unit, Pêma lowers overall system cost, occupies less space, improves energy effiency, and both speeds and simplifies system installation and programming. Four and eight amplifier channel versions are available at both 125 and 250 Watts per channel. Full 96kHz performance is available on 32-bit SHARC processors with utterly transparent audio. Pêma changes the way consultants and integrators approach sound system design. With only the addition of input sources and output speakers, Pêma is a 'house-of-worship-in-a-box' or a 'restaurant-in-a-box' or a 'bar-in-a-box'. Pêma delivers an elegant solution with less cabling, less rack space, and less installation time, using proven DSP and amplifier technology that will awe clients with its simplicity, sophistication, and reliability. In addition to DSP algorithms such as ambient noise compensation, advanced automatic feedback suppression, automatic mixer, and a full complement of filters, EQs, delays, and the like, Pêma offers DSP control of the amplifier functionality as well: selection of bridge-mode operation, HPF settings for constant voltage system networks, stereo-linking of channel pairs, MIC/LINE/TEL-PAGE functions on channel 1, full control of ducking priorities, and full-range remote-gain control capability. Pêma I/O count and formats are ideal for small- to mid-sized installations. Each variant has eight balanced input channels that are software selectable for mic or line levels. The first channel may also be set for a transformer isolated, TEL-PBX level. Additionally there are eight pairs of summed-mono RCA connectors optimized for consumer line level devices. Eight preamp auxiliary outputs allow integrators to route signals from the matrix mixer to anywhere the system requires. Both CobraNet and EtherSound digital I/Os are fully supported. Read more

About the Ashly PEMA 4250 4-Channel Power Amplifier, 250W at 4 Ohms, 8x8 DSP Matrix

The Ashly PEMA 4250 is an all-in-one powered audio matrix processor designed to streamline system design for commercial multi-zone installations. This unit integrates a four-channel power amplifier, an 8x8 digital signal processing matrix, and mixing capabilities into a single 2U rack-mountable chassis. Each amplifier channel delivers 250 watts into a 4-ohm load, providing substantial power for driving 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, allowing for complex audio distribution and tuning without the need for 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 can be configured to 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 PEMA 4250 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.
