DSP MORGAN SOUND LM248 4 In/8 Out Digital Speaker Processor
The Crossover Digital utilizes 32-bit DSP conversion processing and high-performance 24-bit AD/DA, with a 96kHz sampling rate.
- It features 4 input channels and 8 output channels, with professional calibration software.
- Supports 128 preset modes, and the status of the entire unit as well as each individual preset can be stored and recalled separately.
DSP Morgan Sound LM248 4 In/8 Out Digital Speaker Processor LM Serial
This 4-input 8-output loudspeaker processor uses the latest fourth-generation SHARC ADSP-21488 400Mhz floating point DSP with powerful DSP processing capabilities.
Each input and output has a 16-band parametric filter, gain control, noise gate function, RMS limiter, built-in pink/white noise generator, and adjustable delay.
The slope of the divider ranges from 6dB/Oct to 48dB/Oct.
The delay step accuracy is 0.01ms, and the level gain accuracy is 0.1dBu, which can meet the good scene adjustment.
The delay step accuracy is 0.01ms, and the level gain accuracy is 0.1dBu, which can meet the good scene adjustment.
