TKL 4.8PRO Digital Audio Processor Multifunction Audio Processor 4 Input 8 Output for Bars Stages

Features:
- 4 in 8 out digital audio processor
- Noise gate function: It reduces normal noise in the system
- Upgraded and multifunctional: ADSP21489 the fourth generation SHARC processor for ADI is used. Built-in routing/gain/delay/limiting/mute/parametric equalization/graphical equalization/high-pass and low-pass filters/all-pass filters and phases and many other audio algorithms
- Sound acquisition rate: 96KHz, higher timbre reproduction
- USB driver: no driver required and ready to use
- Panel operation: simple and intuitive
- Main functions: voltage limit, parametric equalization, crossover, delay and gain (with noise gate, graphical equalization and all-pass filtering)
- Delay parameters: input 1000ms; Output 1000ms
- Equilibrium parameters: 10 segments of parametric equalization input; Output 10 segments (with 31 segments per channel input graphic equalization)
- Processing chip: ADSP21489 the new fourth-generation SHARC processor for ADI
- WiFi function: with built-in wireless WiFi reception, it can realize wireless remote debugging
- 96KHz acquisition rate: 96KHz sound acquisition rate and higher timbre reproduction. The higher sample rate avoid audio loss that can occur when converting to a lower sample rate
