Connecting and controlling an amplifier for networked systems has now
been simplified with Ashly's NE Series amplifiers. Network Enabled (NE) amplifi-
ers offer ease of use, setup and control using standard 10/100 Ethernet proto-
col and Protea NE Software. No special outboard control units are needed.
Four, four-channel models with output power at 250W are available to fill a
wide variety of low impedance, 25V, 70V and 100V performance installation
or constant voltage applications. NE Series amplifiers are offered two ways;
standard input with euroblock connectors and "pe" (Protea Enabled) with
euroblock input connectors and world renowned Protea DSP signal process-
ing.
The DSP signal processing library is extensive and utilizes two SHARC 32-bit/
96kHz processors. Processing blocks include Graphic, Parametric, Notch and
Shelving Equalization, High-, Low- and All-Pass Filters (HPF/LPF/APF) with up to
48dB/Octave slopes, Delay, Compressor/Limiter, Gate, Ducking, Auto-leveler,
Gain and Signal Generators (sinewave, white and pink noise). A full Matrix
Mixer with assignable routing allows any input to drive any or all amplifier out-
puts. Presets can be used to store and retrieve global parameters of an entire
amplifier's control surface and DSP section.
Additionally, each amplifier also provides DC voltage control of the attenu-
ators 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.
Four-channel Mic-pre, AES/EBU, and Cobranet modules will be available as
options. Eight-channel NE series amplifiers are also available
