Ashly ne4250.70 4-Channel Network Power Amplifier, 250W at 70V

The Ashly ne4250.70 is a 250-watt Constant Voltage 70V @ 4 Ohm, four-channel amplifier. Connecting and controlling an amplifier for networked systems has now been simplified with Ashly’s NE Series amplifiers. Network Enabled (NE) amplifiers offer ease of use, setup and control using standard 10/100 Ethernet protocol and Protea NE Software. No special outboard control units are needed. Additionally, each amplifier also provides DC voltage control of the attenuators which makes it a snap to control volume from remote locations, preset recall, Remote Power Standby and data in and out ports for connecting accessories like the WR-5 to control user selected parameters. There are LED indicators for power, standby, protect, network communications and each channel has a four-step signal meter, bridge mono, temperature and current indicators.
