About Ashly PEMA 8250

What sets the PEMA 8250.70 8-Channel Amplifier apart in the realm of zone sound systems is its unparalleled combination of advanced Protea Digital Signal Processing (DSP) and robust amplifier performance, all neatly packaged within a space-saving two-rack unit. This powerful amplifier is designed to revolutionize sound system design, offering a sophisticated yet straightforward solution that significantly reduces system costs, space requirements, and installation time.

Crafted for high-quality audio performance, the PEMA 8250.70 boasts full 96kHz capabilities on 32-bit SHARC processors, ensuring transparent audio that meets the demands of audiophiles and professionals alike. With options for four or eight amplifier channels, each capable of delivering 125 to 250 Watts per channel, this amplifier is engineered to handle even the most challenging sound reinforcement scenarios with low distortion and high reliability.

The built-in Protea DSP offers a suite of advanced algorithms, including ambient noise compensation, automatic feedback suppression, and a comprehensive array of filters, EQs, delays, and more. The amplifier's DSP control extends to bridge-mode operation, high-pass filter settings for constant voltage systems, stereo-linking of channel pairs, and full-range remote-gain control, making it a versatile choice for small to mid-sized installations.

Connectivity is a breeze with eight balanced input channels, software-selectable for mic or line levels, and the first channel offering a transformer-isolated TEL-PBX level. Additionally, eight pairs of summed-mono RCA connectors cater to consumer line-level devices, while eight preamp auxiliary outputs provide flexible signal routing options.

Programming and deployment of the PEMA 8250.70 are remarkably user-friendly, thanks to the standard 10/100 Ethernet protocol and Ashly's Protea ne Software on a PC platform. Hot-plug DSP placement and automatic DHCP network IP configuration streamline the setup process, while lockable front panel controls and multi-level software security with password access ensure a secure audio system.

The PEMA 8250.70's architect and engineering specifications reflect its commitment to excellence, with each input and output channel featuring individual mute capabilities and six configurable processing blocks. The matrix mixer allows for intricate signal routing and gain-sharing automatic mixing, ensuring that every output is tailored to the specific needs of the installation.

With a frequency response of +/-1dB from 20Hz to 20kHz and a signal-to-noise ratio greater than 102dB, this amplifier delivers pristine sound quality. LED indicators provide at-a-glance monitoring of signal levels, clip/mute status, and system health. The unit's temperature-dependent speed-controlled axial fan ensures optimal operating conditions, maintaining the amplifier's durability and longevity.

The PEMA 8250.70 is a testament to Ashly's legacy of producing high-quality, reliable audio equipment, making it an ideal choice for audio professionals seeking an advanced network audio amplifier with the convenience and sophistication of integrated DSP and network control capabilities.
