Overview:
The RCF DX 4008 is a complete 4 input - 8 output digital loudspeaker management system designed for the touring or fixed sound installation markets.
- The absolute latest in available technology is utilized with 32-bit (40-bit extended) floating point processor and high performance 24-bit Analog Converters
- The high-bit DSP prevents noise and distortion induced by truncation errors of the commonly used 24-bit fixed-point devices
- A complete set of parameters include I/O levels, delay,polarity, 6 bands of parametric EQ per channel, multiple crossover selections and full function limiters
- The DX 4008 can be controlled or configured in real time on the panel or with the intuitive PC GUI accessed via the RS 232 interface.
- Software upgrade for CPU and DSP via PC keeps the device current with newly developed algorithms and function once availabl
- Multiple setup storage and system security complete this professional package.
Features:
- 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
Applications:
- Touring sound
- Fixed installations
Front Panel Features:
1.) Mute Keys - Mute/Unmute input and output channels. When an input channel is muted , a red LED will be lit for indication
2.) Gain / Menu Keys - Selects the corresponding channel for the LCD menu display and is acknowledged by a green LED. The last modified menu will be displayed on the LCD. Linking multiple channel is accomplished by pressing and holding the first channel key then pushing the other desired channels. This eases programming for same parameters across multiple channels . Multiple inputs can be linked together and multiple outputs can be linked together. Inputs and outputs can be linked separately
3.) Peak Level LED - Indicates the current peak level of the signal : Signal (-42 dB), -6dB,-3dB,Over/Limit. The Input Over LED references to the devices maximum headroom. The output Limit LED references to the threshold of the limiter
4.) LCD - Shows all the necessary information to control the unit
5.) Rotary Thumb Wheel - Changes parameter data values. The wheel has travel velocity sensing which ease large incremental data modifications. For modifying delay and frequency (1 Hz resolution), pressing the speed key simultaneously will increment/decrement the data value by 100x
6.) Menu Control Keys - There are 6 menu keys
- <<Menu (Menu Down)
- Menu>> (Menu Up)
- <<Cursor (Cursor Down)
- Cursor>>(Cursor Up)
- Enter/Sys/Speed
- Exit
The functions of each key is explained below:
- <<Menu : Previous Menu
- Menu>> : Next Menu
- <<Cursor : Previous cursor position in the menu screen
- Cursor>> : Next cursor position in the menu screen
- Enter/Sys/Speed : Enter is used only in the System Menu to proceed with selected actions Sys enters the System Menu from the main menu Speed modifies delay and frequency (1 Hz resolution mode) data values by 100 x
- Exit : Exit to the Main Menu
Rear Panel Features:
1.) Main Power - Connects via a standard IEC socket. A compatible power cord is supplied with the unit. The voltage input is eithr 115VAC or 230VAC and is clearly specified on the unit. Voltage requirement has to be stated upon ordering
2.) Main Fuse - T0.5A - 250V for 115VAC and T0.25A -250V or 230 VAC
3.) Power Switch - Switches On/Off
4.) RS232 - a standard female DB9 socket for PC connection
5.) XLR input and outputs - separate 3-pin XLR connectors are provided for each audio input and output
All inputs and outputs are balanced:
- Pin 1 - ground (shield)
- Pin 2 - hot (+)
- Pin 3 - cold (-)
