| 4 intrări, 8 ieşiri, Sistem digital de control |
DX 4008 este un sistem digital de control cu 4 intrări şi 8 ieşiri, destinat instalaţiilor de sunet fixe sau de concert.
Noutate absolută în tehnologia actuală, este prevăzut cu procesor de 32 biţi cu diviziune mobilă (extensibilă până la 40 biţi) şi convertoare analogice de performanţă de 24 biţi.

 |
Rata de semplare poate fi setată la 96KHz. Procesorul de semnal digital cu diviziune mobilă elimină zgomotul şi distorsiunile induse de erorile de trunchiere care apar la procesoarele de 24 biţi cu diviziune fixă, folosite în mod comun.
Setarea completă a parametrilor include nivelele de semnal intrare/ieşire, delay, polaritate, 6 benzi EQ parametrice per canal, selecţii crossover multiple şi limitatoare. Rezoluţia de un 1Hz asigură un control precis al frecvenţelor. În întâmpinarea oricăror cerinţe, intrările şi ieşirile de semnal pot fi rutate în configuraţii multiple.
DX 4008 poate fi configurat sau controlat în timp real de pe panoul frontal sau prin intermediul calculatorului via interfaţa RS 232. Upgradarea software-ului pentru CPU şi DSP via PC asigură posibilitatea folosirii algoritmilor şi funcţiilor nou dezvoltate. |
| CARACTERISTICI |
| The DX 4008 is a complete 4 input - 8 output digital loudspeaker management system designed for the touring or fixed sound installation markets |
| Sampling rate can be set to 96kHz |
| Precise frequency control is achieved with its 1 Hz resolution |
| Inputs and outputs can be routed in multiple configuration to meet any requirements |
| The DX 4008 is shipped with a special PC Graphic User Interface (GUI) application - XLink |
| XLink gives the user an option to control the DX 4008 unit from a remote PC via the RS232 serial communication link |
| The GUI application makes much easier control and monitor the device, allowing the user to get the whole picture on one screen |
| Programs can be recalled and stored from/to PC's hard drive, thus expanding the storage to become virtuality limitless |
