TKL-PA48S High-level Four Input and Eight Output Digital Audio Processor 32-Bit DSP Processor with 96KHz Sampling Frequency

TKL-PA48S High-level Four Input and Eight Output Digital Audio Processor 32-Bit DSP Processor with 96KHz Sampling Frequency

Features:
- 96KHz sampling frequency, 32-bit DSP processor, 24-bit A/D and D/A conversion.
- Multiple frequency division modes can be flexibly combined, and the high and low pass frequency division points can reach 20Hz~20KHZ.
- USB2.0, USB3.0 and RS485 are provided to connect with computers. The RS485 interface can be connected to 250 devices at most and controlled by external computers at a distance of more than 1500 meters.
- It is very convenient, intuitive and simple to directly use the function keys and pullers on the panel to set the function or connect the computer to control it through PC control software.
- A single machine can store up to 30 groups of user programs.
- The control function of the locking panel can be set through the SYSTEM key of the panel to prevent the parameters from being modified.
- Each input and output has six independent full-parameter equalization, with the adjustable gain range of ±20dB. At the same time, you can also choose five equalization modes: parametric, high-pitched, low-pitched, first-order all-pass and second-order all-pass.
- Each input channel has adjustable noise gate, and each input channel has two full-parameter adjustable dynamic equalization (DEQ) and automatic gain control.
- 2 x 24LCD blue backlight shows the function setting, and 5-segment LED shows the precise digital level meter, mute and editing status of input/output.
- Each input and output has delay, phase control and mute settings. The maximum delay can be 1000ms. The delay units can be milliseconds (ms), meters (m) and feet (ft). The delay can be adjusted through coarse and fine adjustment modes.
- The output channel can also control the compression, limiting and selection of input signal channels, and can copy all parameters of one channel to another channel for linkage control.
- The central control can be connected through RS485 interface to control the mute of matrix and channel.
- Support the device input, output and system functions to set the password and lock them respectively to achieve data confidentiality.
- The device software has a built-in central control code generator, which can switch between Chinese and English with one key.
- It can be connected with the computer through the external communication converter, and can realize the remote control of the Internet.
