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. Inputs are precision balanced and RF protected, while outputs may be wired balanced or unbalanced. All audio connections use XLR and 1/4" phone jacks for greater flexibility. Up to sixteen different audio channels can be linked together for expanded system control using the main 4.24G and slave units 4.24GS, 2.24GS, 4.24PS, and 2.24PS.
1.3 USER INTERFACE
A key advantage to the Protea system is that all audio functions are intuitively laid out so that a minimum number of keystrokes can quickly change a setting on any channel in real time. With this in mind, two entirely different methods to control the signal processing functions in Protea products have been developed, one using an innovative keyboard interface which is similar to an analog EQ face, while the other uses custom Windows95/98™ software for the PC.
Keyboard Interface: The keyboard interface on either the main (4.24G) or remote control (4.24RD) displays information on a 240 x 64 pixel flourescent backlit LCD screen. The combination of the analog-style keyboard and LCD makes navigating around the Protea amazingly simple. The 4.24RD remote control is essentially the "front end" of the 4.24G, allowing remote processor control from within reach of the equipment rack, or from a control room over 1000 feet away. Note: The 4.24RD remote controls the main and graphic EQ slaves, but not the two parametric slaves, 4.24PS and 2.24PS. Parametric slaves require PC control using Protea System Software.
Protea System Software: The second type of interface uses Ashly PROTEA SYSTEM SOFTWARE for the Windows95/98 environment, which allows complete PC control through a computer's RS-232 serial port. Protea System Software controls the main 4.24G, and both graphic and parametric Protea slaves. Protea system software is supplied with slave units, or can be downloaded at no cost from the Ashly web site. At this time, there is no Mac version of Protea System Software available.
Contact Closures: For Protea slave units, a small switch can be connected for recalling up to six different pre-programmed settings, or scenes, without the risk of mistakenly changing those settings. Ashly offers a six position rotary switch assembly which can be mounted to a standard electrical switch box, or can be wired into a custom installation. See section 6.4 for details.
1.4 PROTEA SYSTEM CONCEPTS
It is important when learning about the Protea to understand several key terms, which are defined below.
Preset Number . . . . 128 different user-defined settings which can be recalled to any channel
Preset Name . . |
. . |
. . Every preset number can have an associated name, but it is not required |
Local Channel |
. . . . The physical path in a unit to which audio signals are connected |
|
MIDI Channel |
. . . . One of 16 different logical channels. A local channel can be assigned any MIDI channel |
|
Current Channel |
. . The local channel which is currently selected on the LCD display. |
|
Bank . . . . . . . . |
. . |
. . On a master or remote unit, a bank combined with a channel selects a MIDI channel number. |
|
|
ex. Bank B + channel 1 selects MIDI channel 5, Bank D + ch. 4 selects MIDI channel 16 |
Menu . . . . . . . . |
. . |
. . Menu items select audio and setup screens for fast access to all Protea features |
Softkey . . . . . . . |
. . |
. . Any key having multiple uses, depending on the menu item selected |
Dialog Box . . . |
. . |
. . A pop-up window that requests a response from the user, or displays a change |
Master . . . . . . . |
. . |
. . The controlling 4.24G unit in a multi-unit Protea system. |
Slave . . . . . . . . |
. . |
. . Any piece in a multi-unit Protea system which responds to system commands from another unit |
Channel Linking |
. . 2, 3, or 4 local channels of a 4.24G may be linked together so that they share the same |
|
|
|
settings, but maintain discrete audio paths |

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. Most units distributed outside the US are preselected and labeled for 230VAC, 50-60Hz and are shipped with the appropriate power cord. In the event of fuse failure, replace only with same type and rating fuse. If the fuse is internal, refer the product to a qualified service technician for fuse replacement.
The 4.24RD remote control is phantom powered from its host through two standard three-conductor XLR cables.
3. UNPACKING
As a part of our system of quality control, every Ashly product is carefully inspected before leaving the factory to ensure flawless appearance. After unpacking, please inspect for any physical damage. Save the shipping carton and all packing materials, as they were carefully designed to reduce to minimum the possibility of transportation damage should the unit again require packing and shipping. In the event that damage has occurred, immediately notify your dealer so that a written claim to cover the damages can be initiated. The right to any claim against a public carrier can be forfeited if the carrier is not notified promptly and if the shipping carton and packing materials are not available for inspection by the carrier. Save all packing materials until the claim has been settled.
4. TYPICAL PROTEA APPLICATIONS
The Protea SYSTEM II product family includes five audio processors, a remote control, and Protea System Software. Various Protea units can be combined to expand the capabilities of a system, adding channels, utilizing remote control, or connecting to a PC. The following illustrations indicate some typical Protea systems. See SYSTEM CONFIGURATION chart on p. 20 for specific switch and preference settings.
4.1 STAND-ALONE
Only the 4.24G can be used as a fully selfcontained processor, while any slave unit can function independently once it has been properly set up through external hardware or software.
4.2 SINGLE UNIT WITH REMOTE CONTROL
The remote control unit (model 4.24RD) connects to the main 4.24G or any other slave unit, and can run up to 1000 ft. from the host audio unit.
