Ashly PEMA 4250.70 4-Channel 250W Powered Processor for 70V Systems, 8x8 DSP Matrix

$3,099.00 - $3,639.00

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.

About the Ashly PEMA 4250.70 4-Channel 250W Powered Processor for 70V Systems, 8x8 DSP Matrix

The Ashly PEMA 4250.70 is a fully integrated, network-powered audio matrix amplifier designed as a centralized hub for commercial multi-zone sound systems operating on 70V distributed lines. 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 70V (and typically 100V) constant-voltage speaker lines, making it an ideal, self-contained solution for powering extensive background music and paging networks in shopping malls, airports, hotels, and campuses. The integrated 8x8 DSP matrix provides complete routing flexibility and comprehensive processing—including EQ, dynamics, delay, and crossovers—for all inputs and outputs, enabling complex zoning and acoustic tuning within the unit.

Network connectivity is central to its design, allowing for complete remote configuration, control, and monitoring via Ethernet. Through Ashly's software, system integrators can design the audio matrix, set processing parameters, adjust levels, and monitor system health from a central computer. The four amplified outputs drive speaker zones directly, while the additional four processing outputs can be used for feeds to external devices or for system expansion. This integrated approach drastically simplifies installation, reduces component count, and provides a software-defined hub for the entire audio system, offering exceptional scalability and management ease.

Built for 24/7 reliability, 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 4250.70 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 on 70V systems.
