Introducing the Ashly Protea System II digital equalizer/ processors, now including two- and four-channel parametric
processors. The System II offers all the remarkable versatility and control of the original Protea series while providing both parametric and graphic filter devices with enhanced sound quality and exceptional signal-to-noise, making it well suited for applications requiring the installation of precision, tamper-proof equalization and signal processing. Models 2.24PS and 4.24PS represent the next logical step in audio processing to be introduced in the Protea Series, and feature 12 bands of fully programmable parametric equalization, adjustable high and low shelf filters and all the improvements found in System II. All Protea System II devices are U.L. and C.U.L. listed. We’ve taken the Protea’s already impressive and intuitive user interface, extensive control options, expansion possibilities (up to 16 channels of EQ, using 2- and 4-channel slave units), built-in compressor/limiter, and much more—and added a host of truly professional improvements.

The System II features a totally redesigned DSP chain (with new 100MHz DSP and 24-bit A/D/A), >110dB dynamic range, <–90dBu signal-to-noise ratio, 1.364-second time delay (quadruple that of the previous Protea!), contact closure scene recall, seamless preset switching to eliminate dropouts, inaudible zipper noise, increased filter adjustment speed, finer compression ratio steps, easier MIDI channel programming, and more. The result? An expanded and improved series of revolutionary Protea equalizer/processors with audiophile quality specs and the versatility for any application you can imagine. There are three graphic equalizer/processors: the model 4.24G Digital Equalization Main Unit, which is front-panel programmable; model 4.24GS Four-channel Graphic Slave; and model 2.24GS Two-channel Graphic Slave. Filter bands are true reciprocating filters spaced at 1/3-octave on ISO centers with a fixed Q.

Two parametric equalizer/processors are available: model 4.24PS Four-channel Parametric Slave, and model 2.24PS Two-channel Parametric Slave. Filter bands are adjustable from 1/25th to 3.3 octaves over a frequency range of 20Hz to 20kHz. Filter level control is adjustable from –20dB to +10dB in 0.5dB increments. High and low shelf filters are adjustable from 1.6kHz to 20kHz and 20Hz to 240Hz respectively. Programmability of all five processors can be accomplished with Ashly’s exclusive Protea System Software (version 2.0) interface for the Windows™ 95 or 98 environment. Additionally, the 4.24RD Remote Control is available for controlling graphic models (4.24G, 4.24GS, and 2.24GS).

Applications include indoor and outdoor sound reinforcement equalization, room equalization/leveling, microphone equalization, reference monitoring, and audio editing/recording where general signal enhancement or sound shaping using graphic equalization or precise control for eliminating unwanted frequencies using parametric equalization is needed. Ashly is an SIA Software Smaart Partner. The Ashly Protea Series supports SIA Smaart-Pro’s plug-in architecture and is controllable directly from within Smaart-Pro.

Full control of the 4.24G is accomplished from the front panel in an intuitive and straight-forward layout. It’s like using your old analog equalizer, only with extra features and benefits to simplify your audio chain requirements. Housed in an all-steel 2RU package, the 4.24G has all the audio processing tools needed for flawless equalization and sound control. In addition to 28 bands of 1/3-octave EQ are a programmable compressor/limiter for speaker protection and programmable delay of up to 1.364 seconds for time delay applications required by speaker arrays and clusters or monitor speakers. Individual, programmable 24dB/octave high- and low-pass filters allow you to zero in and fine tune the audio spectrum you need to work in. A large 240 x 64 fluorescent backlit display keeps you con-stantly informed of every parameter, function and utility, including metering and user preferences.
