Ashly pema 4250.70 Network Power Amplifier with Protea DSP (4 x 250W @ 70V)

Four-Channel Protea-Equipped Power Amplifier, 250 Watts per Channel at 70 Volts

Ashly Audio's promise to "Simplify Integration" continues with pema (Protea Equipped Media Amplifier), a unique powered processor. Pema 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, pema lowers overall system cost, occupies less space, improves energy efficiency, 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 for utterly transparent audio.

Pema changes the way consultants and integrators approach sound system design. With only the addition of input sources and output speakers, pema is capable of handling everything else for small- to mid-sized sound systems. Pema is a 'house-of-worship-in-a-box' or a 'restaurant-in-a-box' or a 'bar-in-a-box' or a 'you-name-it-in-a-box.' Pema 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, pema 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.

Pema's 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.

As a member of the respected Protea DSP lineage, pema is remarkably easy to program and deploy. All set up is accomplished using standard 10/100 Ethernet protocol and Ashly's Protea NE Software on a PC platform. Hot-plug DSP placement allows users to insert any function into any channel block, even when running live audio. Automatic DHCP network IP configuration reduces network set up time. Lockable front panel controls and multi-level software security with password access guarantee a tamperproof audio system.
