Operating Manual - NE Multi Channel Power Amplifier 1. INTRODUCTION Thank you for your purchase of this NE (network enabled) multi channel power amplifier. The NE power amplifiers combine lightweight, state of the art, high efficiency switching technology with integrated Ethernet control, and use optional modular expansion cards to provide comprehensive internal DSP processing, AES/EBU input, and networked digital audio (Cobranet) input.
Operating Manual - NE Multi Channel Power Amplifier The basic NE multichannel amplifiers come in either four channel or eight channel configurations, with Euroblock input connectors standard or optional XLR connectors. Output connectors are Euroblock only.
Operating Manual - NE Multi Channel Power Amplifier Physical Description Each model in the NE Multichannel series is 2RU, and weighs 22 pounds (10kg) or less. The model number is indicated in the lower left corner of the front panel. Amplifier Front Panel 1. Mounting Holes – For rack mounting. 2. Power Switch – Switches the unit on or off. Note: The power switch can be disabled from Proteane Software 3. Status LEDs – Indicate status of: Power, Standby, Protect, Power Switch Disable, and Comm activity 4.
Operating Manual - NE Multi Channel Power Amplifier Amplifier Rear Panel 1. Optional Cobranet Card CNM-2 – Installation of this option allows this amplifier to be part of a Cobranet audio network. 2. Optional AES/EBU Input - Installation of this option allows for AES/EBU digital input. 3. Ethernet Port - This jack offers ethernet control and monitoring of basic amplifier functions using Protea ne software. 4. Input Connector - This is used for a three wire (G, +, -) balanced input.
Operating Manual - NE Multi Channel Power Amplifier 4. REMOTE AMPLIFIER CONTROL ON/OFF/Remote Standby The NE multichannel amplifiers have three possible states, OFF, ON, and STANDBY, each with a status LED on the front panel.
Operating Manual - NE Multi Channel Power Amplifier The WR-5 is a microprocessor based remote control unit which can be used with the NE multichannel amplifiers. The WR-5 is designed to fit into a standard electrical wall box. Up to four WR-5 remotes can be phantom powered from one amplifier, and adding more remotes is possible using an external power supply.
Operating Manual - NE Multi Channel Power Amplifier 5. PROTEAne SOFTWARE Proteane software offers a comprehensive suite of tools for controlling Ashly NE multichannel amplifiers as well as other Ashly products. The standard NE multichannel amplifiers allow for ethernet control and monitoring of power functions, level, mute, and polarity. With the DSP option installed, software control and monitoring of major audio functions can be custom configured on a per channel basis, as well as through linked channels.
Operating Manual - NE Multi Channel Power Amplifier The Amplifier Control Surface 4) Offset link group - Up to eight groups are available for the purpose of linking similar function parameters across multiple channels. In addition to the control surface secondary level control (not the main fader), most DSP functions have a link group check box in their work window to assign a specific parameter to one of the eight link groups if desired.
Operating Manual - NE Multi Channel Power Amplifier The DSP Window Extensive online help information is available for all DSP blocks. Look in the Protea ne Software Help Menu/ Contents and Index/Contents/Protea NE Products/PE Multichannel Amplifiers/DSP Control for details of all DSP functions. The key features include: 1) Input Channel Number - Right click on this to bring up Clear, Copy, Link, and Sub Preset functions for that input channel. 2) Input Channel Name - The user can name each input channel.
Operating Manual - NE Multi Channel Power Amplifier 4) Pluggable Input DSP Tools - Six boxes are available for custom configuration of pluggable DSP processing blocks. Available DSP blocks include Dynamics controls, Gain functions, Graphic and Parametric EQ, Cross over functions, Delay, Metering, and a signal generator. 5) Input/Output Matrix Router - Any input can be routed to any or all outputs. Click and drag from the input to output to assign routing.
