NE Series specifications
Connecting and controlling an audio processor for networked systems has
now been simplified with Ashly’s NE-Series Protea ne24.24M digital signal
processor. This Network Enabled (NE) processor offers ease of use, setup and
control using standard 10/100 Ethernet protocol and Protea NE Software. No
special outboard control units are needed.
The ne24.24M Matrix Processor uses modular expansion cards to provide up
to twenty-four channels of audio matrixing and processing. The base unit of-
fers a four-input/four-output configuration. Each input and output expansion
card has an individual DSP processor allowing you to expand the base unit’s
total inputs or outputs four channels at a time. These cards are easily installed
in the field without the need to reprogram the device.
Matrixing allows you to route any input to any output and control individual
levels once they have been assigned. Fixed path architecture and extensive
processing power per channel will reduce the amount of time it takes to set
up your system. All programming is accomplished using Ashly’s Protea NE
Software on a PC platform. No front panel controls and multi-level software
security assures you a tamperproof audio system. Input channel processing
blocks include Mic Preamp with Phantom Power, Gain, Delay, fifteen EQ
Filters, Gate, Autoleveler and Ducker. Inputs may be configured as either mic
or line level. Output channel processing blocks consist of a Cross Point Mixer,
HPF/LPF, Delay, fifteen EQ Filters, Gain and Limiter. The cross point mixer in the
output section allows you to route any input to any output at any level and
mute any input at any output without affecting the true input configuration.
The HPF/LPF block offers Bessel, Butterworth and Linkwitz-Riley filters with 12,
18, 24 and 48dB/octave slopes.
Whether you are designing or installing a system for corporate boardrooms,
restaurants, courtrooms, houses of worship, left/center/right theatres, audi-
toriums or conference centers, the Protea ne24.24M will more than satisfy
your requirements for any zoned system requiring input/output matrixing with
signal processing.
