About Ashly ne4250.70pe

Before diving into the technicalities, let's introduce the NE4250.70PE 4-Channel Network Enabled Power Amplifier, a powerful and advanced piece of audio equipment that is designed to deliver high-quality sound with low distortion. This durable and reliable amplifier is built around an energy-efficient Class-D platform with a switching power supply, making it an ideal choice for professional audio applications and large venues.

This high-powered amplifier is network-enabled, offering ease of use, setup, and control using standard 10/100 Ethernet protocol and Protea ne Software. There's no need for special outboard control units, making it a versatile and user-friendly option for all your audio needs.

The NE4250.70PE is more than just a standard network amplifier. It comes with an onboard Protea DSP Processor, allowing for advanced signal processing and network connectivity. This amplifier can be customized for any installation by adding your choice of AES3 inputs, mic pre inputs, CobraNet, or Dante modules.

The four-channel power amplifier is capable of delivering a minimum power of 250 Watts RMS per channel into 70V loads with all channels operating. When switched into bridged-mono mode, channels 1+2 or 3+4 of the amplifier can deliver at least 500 Watts RMS into a 140V load.

The NE4250.70PE features Euroblock input and output connectors, balanced analog inputs, and remote standby for power up. It also offers DC remote level control and contact closure preset recall. The amplifier provides Ethernet control and monitoring of power functions, level, mute, polarity, temperature, current, and amplifier fault conditions.

The front panel provides the status of power, standby, protect, power switch disable, signal level, bridge, over-temperature, over-current, and Ethernet communication. The power amplifier comes with an internal factory-installed digital signal processing (DSP) option controlled using Protea (network enabled) software.

The Protea DSP is compatible with Microsoft Windows 8, 7 (Vista/XP) 32 & 64 bit systems, making it intuitive and easy to navigate for audio professionals. The amplifier is designed to mount in a standard 19-inch rack using two spaces and weighs 23 pounds or less, making it a compact and lightweight solution for your audio needs.

In conclusion, the NE4250.70PE 4-Channel Network Enabled Power Amplifier with Protea DSP and CNM-2 CobraNet Option Card is a powerful, advanced, and reliable choice for delivering high-quality sound in a variety of settings.
