Operating Manual - PROTEA SYSTEM II Digital Audio Products 1. INTRODUCTION Thank you for your purchase of this Ashly Protea SYSTEM II digital audio product. The Protea SYSTEM II series builds on the tradition of quality and value which has earned Ashly its place as a market leader in equalization and signal processing. Please read the entire manual in order to realize all of the powerful features the Protea SYSTEM II series of products has to offer. 1.
Operating Manual - PROTEA SYSTEM II Digital Audio Products 1.2 AUDIO FEATURES The Protea audio components consist of state of the art technologies, beginning with a 24 bit, 48kHz deltasigma A/D converter with 128x oversampling. Digital processing includes EQ, Compression, Limiting, Shelving, Highpass and Lowpass Filters, and Time Delay, taking place in a 100MHz Motorola DSP56303 high performance DSP processor. D/A conversion uses a 24 bit delta-sigma converter with 128x oversampling.
Operating Manual - PROTEA SYSTEM II Digital Audio Products 2. AC POWER REQUIREMENTS Note: The AC power switch for model 4.24G is on the back panel. All Protea devices will perform normally from 90 to 125VAC. A standard IEC-320 AC inlet is provided on the rear panel to accept the detachable power cord shipped with the unit. Units distributed within the United States are preselected for 115VAC, 50-60Hz and should be plugged into a standard NEMA 5-15 3-wire grounded AC receptacle.
Operating Manual - PROTEA SYSTEM II Digital Audio Products 4.4 WITH PROTEA SYSTEM SOFTWARE 4.5 WITH THIRD PARTY MIDI SYSTEMS Ashly PROTEA SYSTEM SOFTWARE adds flexibility by allowing comprehensive system control of main or slave units from a PC using the RS-232 Serial port. Note: the Data Config Switch (Switch "B" On Slaves) must be pressed Protea System "IN" only on the unit conSoftware nected directly to the PC, RS-232 and only if additional units are connected through the Main Or Slave XLR Data cables.
Operating Manual - PROTEA SYSTEM II Digital Audio Products while any dependent channels will show a flashing LED to indicate linked status. Although the audio paths remain separate, the linked channels now act as one. Any action taken on the Current Channel will also affect the Linked Channel(s). To unlink a channel, simply repeat the linking process to toggle the linked channel off. Note: When two channel keys are simultaneously pressed, a pop-up screen will say "Changing Link Status".
Operating Manual - PROTEA SYSTEM II Digital Audio Products Ratio (RAT) is the degree of attenuation to the signal above the limiter threshold point. As the ratio increases, less signal is allowed to exceed the threshold. For example, with the ratio set at 10:1, a 10dB increase in input level results in just a 1dB increase in output level.

Up to 50 different scenes may be stored, with each scene capable of controlling up to sixteen local channels. Note: Saving a Scene does not store the parameter details within each preset, just the currently loaded preset numbers.

MIDI channel assignment for model 4.24G is done in the UserPref menu, while Slave units have front panel recessed tactile switches adjacent to each LED readout for MIDI channel assignment.
Operating Manual - PROTEA SYSTEM II Digital Audio Products 7. MIDI IMPLEMENTATION ***NOTE! Read this section before using several Protea units controlled from a Master or Remote. 7.1 MIDI AND THE 4 BANKS There are 16 MIDI channels, and any local channel in a Protea system may be independently set to any one of the 16 MIDI channels. This is how 16 different audio channels are controlled from one remote or master.
