Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor 1. INTRODUCTION Thank you for your purchase of this Ashly Protea 3.24CL Digital Crossover/System Processor. The Protea SYSTEM II series builds on the tradition of quality and value which has earned Ashly its place as a market leader in crossovers, equalization, and signal processing. Your new 3.24CL is a three input/six output digital signal processor capable of precise control of a broad range of audio functions.
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor 4. FRONT PANEL CONTROL FEATURES 4.1 Function Keys and Data Wheel To the right of the LCD display are two unlabeled function keys and a rotary data Preset 01 wheel. All audio and system parameters are ed3 x 2-way Crossover ited using these three controls. Each of the two lines of text on the LCD display correspond to a dedicated function key, so that various tasks on both lines may be selected using their respective keys.
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor 4.6 Audio Functions 4.6a Gain Input and Output Gain are separately adjustable from -40dB to +12dB in 0.1dB increments. The output gain menu also provides for selection of input source(s) for a given output channel, as well as polarity of the outgoing signal. Input signal sources are A, B, C, A+B, all three inputs combined, or no input (Off).
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor Narrow (Low) Bandwidth Parametric EQ (PEQ) uses peak filWide (High) Bandwidth ters with the ability to control boost or cut, +20dB frequency center, and bandwidth. Think of one band of parametric EQ as a single graphic +10dB equalizer fader except that the frequency is variable, not fixed, and that the bandwidth, or how 0dB "wide" the filter affects the frequency spectrum at the center frequency, is completely variable.
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor Input (Long) Time Delay For Remote Speakers Speaker on M ain Stage Secondary Speaker 200 ft from M ain Stage Sam e sound arrives at two different times. Fix by delaying secondary speakers 177m S. 4.6d Crossover (Xover) Output channels have time delay as well, but much less than the inputs. This is because output delay is best used to align discrete drivers within a speaker cabinet or cluster, normally quite close together.
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor 24dB/oct Linkwitz-Riley filters are the industry standard, the easiest to use, and the filter type recommended by Ashly. Other filter types are available, but may require polarity switching or other adjustments for proper results. The following paragraphs offer a summary of the three filter types as used in the 3.24CL crossovers.
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor Attack (A__ms) and Release (R__ms) settings adjust the time it takes the limiter to engage and then disengage when the signal increases above threshold and then subsequently falls back below threshold. Attack time is adjustable from 0.5ms through 50ms, while release time ranges from 10ms through 1s. A very fast attack time can sound unnatural, while a very long attack time can miss some of the initial transient.
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor 4.7d Mute The Protea 3.24CL allows the user to mute both inputs and outputs. When muted, an input or output's red Mute LED is lit. When an input or output is selected, pressing the Mute button will toggle its mute function. To quickly mute all outputs, escape out to the top level preset display, then press the Mute button, pressing it a second time to confirm. Additionally, when recalling a new preset number to the 3.
Operating Manual - PROTEA SYSTEM II 3.24CL Crossover / System Processor 5. AUDIO CONNECTIONS All Protea 3.24CL audio connections use three pin XLR jacks, with pin 2 (+), pin 3 (-), and pin 1(G). Inputs and outputs are electronically precision balanced. If an unbalanced signal is fed to an input, the signal should be on the (+) connection (pin 2) and pin 3 must be tied to ground, or significant signal loss will result. In other words, never float pin 2 or pin 3.
