About Ashly 4-Channel Amplifier

It's time to elevate your audio experience with the Network Enabled 4-Channel Amplifier, a powerful device that delivers a robust 250W per channel at 70V. This innovative amplifier is built around an energy-efficient Class-D platform, coupled with a high-performing switching power supply.

The Network Enabled Amplifier simplifies the process of connecting and controlling an amplifier for networked systems. It offers unparalleled ease of use, setup, and control, utilizing the standard 10/100 Ethernet protocol and the advanced Protea NE Software. This eliminates the need for any special outboard control units.

The amplifier comes in two distinct models - the 4-channel ne4250 and the 8-channel ne8250, both rated at 250W per channel. Each model is available in separate HI-Z and LO-Z versions. The NE Series amplifiers are available in two unique platforms - the standard network amplifier and a network amplifier equipped with an on-board Protea DSP Processor.

Customization is at the heart of the NE Series, allowing you to add your choice of AES3 inputs, Dante, or CobraNet card. For our international customers, we offer NE Multi-Channel amplifiers with 240V Line Voltage in either Low-Z or 100V constant voltage output models.

The four-channel power amplifier, ne4250.70, guarantees 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 deliver a whopping 500 Watts RMS into a 140V load.

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

The amplifier boasts a frequency response of 20Hz to 20kHz +/-1.0dB and a Signal-to-Noise ratio greater than 105dB unweighted. The SMPTE intermodulation distortion is less than 0.5% into an 8 Ohm load, 10dB below rated output.

The front panel provides the status of power, standby, protect, power switch disable, signal level, bridge, over-temperature, over-current, and Ethernet communication. The amplifier can be upgraded with factory-installed AES3, CobraNet, or Dante interface options with the addition of a 4-Channel DAC card.

Designed to fit seamlessly into your setup, the amplifier mounts in a standard 19-inch rack using two spaces (3.5. high) and weighs 23 pounds (10.4kg) or less. Experience the power and precision of the Network Enabled 4-Channel Amplifier, your solution for superior sound.
