Ashly ne4250.70pe 4-Channel Power Amplifier with Protea DSP and OPDante Card
Our multi-channel ne (Networked-Enabled) Series Amplifiers are uniquely designed around an energy efficient Class-D platform with a switching power supply.
Connecting and controlling an amplifier for networked systems has now been simplified with ne Amplifiers. This line offers ease of use, setup and control using standard 10/100 Ethernet protocol and Protea ne Software. No special outboard control units are needed.
Choose either the ne4250 (4-channel) or ne8250(8-channel) packages rated at 250W per channel, with separate Hi-Z and Low-Z models. ne Series Amplifiers are offered in two separate platforms-the standard network amplifier or a network amplifier with an on-board Protea DSP Processor. Each can be customized for any installation by adding your choice of AES3 inputs, mic pre inputs, CobraNet or Dante modules.
ne4250.70 with DSP: Architect & Engineering Specs
The four-channel power amplifier shall deliver 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 shall deliver at least 500 Watts RMS into a 140V load. The power amplifier shall include Euroblock input connectors and Euroblock output connectors. It shall have balanced analog inputs.
The power amplifier shall have remote standby for power up, DC remote level control and contact closure preset recall. It shall have Ethernet control and monitoring of power functions, level, mute, polarity, temperature, current, and amplifier fault conditions. Frequency response shall be 20Hz to 20kHz +/-1.0dB. Signal-to-Noise shall be greater than 105dB unweighted and SMPTE intermodulation distortion shall be less than 0.5% into an 8 Ohm load, 10dB below rated output.
The front panel shall provide the status of power, standby, protect, power switch disable, signal level, bridge, over-temperature, over-current, and Ethernet communication. The power amplifier shall have an internal factory installed digital signal processing (DSP) option controlled using Protea (network enabled) software. Each amplifier input channel shall be configured with pluggable DSP blocks to have its own dynamics control, gain functions, graphic and/or parametric EQ, Hi-pass/Lo-pass filters, time delay, metering, and test signal generator.
A mixer section with assignable routing shall allow any input to drive any or all amplifier outputs. Outputs shall have the same DSP functions as inputs, with the addition of FIR filers, and a fast, automated crossover setup. Both inputs and outputs shall copy/paste their settings to other channels, or link with one or more other channels to track their settings. Presets shall be used to store and retrieve global parameters of an amplifier's control surface and DSP section from a file.
Sub-Presets shall allow for a collection of individual DSP function parameters within and across both channels of an amplifier to be stored and recalled as a set, affecting only those parameters which have been tagged. Up to 35 presets/sub-presets shall be stored within the amplifier, and shall be recalled in real time via Ethernet from a computer using Protea software. The power amplifier will be capable of having factory installed AES3, CobraNet, or Dante interface options. The amplifier shall mount in a standard 19 inch rack using two spaces (3.5. high) and weigh 23 pounds (10.4kg) or less.Protea Digital Signal Processing for NE Multi-ChannelProtea is compatible with Microsoft Windows 8, 7 (Vista/XP) 32 & 64 bit systems. Audio professionals find our Protea DSP to be very intuitive and easy to navigate - and you will too.
