All NE two channel power amplifiers come standard with XLR and Euroblock input connectors, and Speakon/
Euroblock output connectors. All models include balanced analog inputs, bridge mono mode, an 80Hz hi-pass filter,
input sensitivity switch, full Ethernet control using Protea
level control using an Ashly WR-1 or equivalent.
All NE two channel amplifiers also include Analog Aux Outputs on XLR and Euroblock connectors. The Aux
Outputs are buffered signals taken just before the power amplifier driver stage. If there is no DSP capability installed in
the amplifier, the Aux Outputs are simply a buffered signal matching the inputs. If the amplifier has DSP installed
however, each Aux Output can be independently configured, in addition to the two main amplifier channels, with its own
DSP processing and any input source, including AES/EBU or CobraNet (if installed) to drive other power amplifiers.
Additional options are available for the NE two channel power amplifiers including the following:
1) Internal DSP Processing - With this factory installed option, and using Protea
each amplifier input channel can 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 allows any input to drive any or all amplifier outputs. Outputs have the same DSP
functions as inputs, with the addition of a fast, automated crossover setup. Both inputs and outputs can copy/paste their
settings to other channels, or can link with one or more other channels to track their settings.
Presets can be used to store and retrieve global parameters of an amplifier's control surface and DSP section from
a file. In addition, Sub Presets 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/subpresets can be stored within the amplifier, and can be recalled in real time via Ethernet from a computer
ne
using Protea
software.
2) AES/EBU Input - Using an optional input card, NE two channel amplifiers can accept AES/EBU digital inputs.
This protocol allows 2 channels of digital audio to be transmitted over a single cable, thus maintaining a completely digital
signal path until just before the power amplification stage. 48kHz & 96kHz data rates are supported.
3) Network Digital Audio (CobraNet) - This option allows the NE two channel amplifier to be part of a net-
worked audio distribution system. CobraNet is a technology developed and supported by Cirrus Logic (www.cirrus.com).
It is a combination of software, hardware and network protocol which allows distribution of multiple channels of real-
time, high quality digital audio over a standard Ethernet Network. For detailed information about CobraNet or its
implementation visit www.cobranet.info.
