SC-3137 Microphone Pre-stage Audio Processor

Sonbs Pre-stage Audio Processor

Features

1. 96KHz sampling frequency, 32-bit DSP processor, 24-bit A/D and D/A conversion

2. 4 channels of optional audio signal input, 2 channels of analog, one group of optical fiber, one group of coaxial, each channel of analog audio signal input sensitivity can be selected, providing 3 groups of 5 microphone inputs, standard 3.1 or 5.1 channel output

3. Fiber and coaxial input for music signal

4. USB interface, WIFI or wired network interface can be connected to the computer, providing remote control and infrared control

5. Directly use the function keys and pulleys on the panel to set the function or connect to the computer to control through the PC control software.

6. Microphone volume, effects volume, music volume and total volume can be controlled by directly rotating the different knobs on the panel.

7. Single machine provides 20 groups of equipment data storage, provides 10 groups of effect data storage, and can copy between devices through PC software

8. The "System" key on the panel can be used to set the password to lock some or all functions of the panel operation, so as to prevent the operation of miscellaneous personnel from destroying the working state of the machine.

9. Accurate digital level meter with Chinese LCD and 6-segment LED display for input/output, mute and editing status

10. Delay and phase control and mute settings for each input and output, up to 30ms input delay and up to 60ms output delay

11. An output channel can also control the effect scale, microphone volume, music volume, and effect volume for that channel

12. The effect has three-section parametric equalization and a pair of high-low filters, and the specific parameters of echo and effect can be adjusted.

13. The main parameters of the channel can be controlled by connecting the S terminal to the central control.
