LX-DSP System Processor
Performs matrix mixing automation and control, using the TI-TMS320C6701 Digital Signal Processor.
This DSP card also holds 32MB SDRAM and 8MB Flash memory, allowing stand-alone operation once
programmed with an automation cue list. The DSP is also interfaced to four relay contact outputs, four
digital sensor inputs and two analogue sensor inputs for control and reading of external devices.
Channels
Maximum 160/512 audio I/O channels
Dynamic Range
192dB
Digital Logic Inputs
LX-DSP cards with serial numbers 0000–0688 require an external pull-up resistor to use the Digital Logic
Inputs. Connect a 1/4W 2K2 resistor between the Digital Logic Input terminal and the +5V reference
voltage. One resistor is required for each Digital Logic Input.
Special DSP ID Numbers
The ID switch on an LX-DSP module can be set to force the LX-300 to erase the flash memory. This is not required
in normal operation. See Special DSP ID Codes (p. 16) for more information.
