PC Interface Controller

  • 【One-year after-sale warranty】The PWM to voltage module converts PWM digital signals to 0 to 10V analog signals. It can be used to switch the signal interface of PLC or other industrial control board. Adjust the output voltage by adjusting the PWM duty cycle. The module is small in size and easy to apply in different places.003cbr003e.
  • Using MCU embedded technology. Easy to operate, can be fine-tuned by potentiometer.003cbr003e.
  • Select the PWM signal input level range by short circuit. The module is small, easy to carry and easy to use.003cbr003e.
  • (current greater than 100mA)，PWM signal receiving frequency range: 1KHZ-3KHZ.
  • When power on for the first time, it is best to do a calibration and debugging: find a signal with a 50% duty cycle and connect it to PWM and GND. Jumper caps set the corresponding voltage range. When the frequency is 1KHZ-3KHZ, use a multimeter to measure the two ports of VOUT and GND. At this time, the meter displays about 5V. Adjust the potentiometer on the board so that the multimeter displays 5.00v.003cbr003e.

Audio-Technica Instrument Condenser Microphone (ATM350U)

  • you want it – the gooseneck won’t flop around no matter how aggressively you move the instrument as you play. The microphone’s cardioid polar pattern isolates the instrument by reducing side and rear pickup, and the switchable 80 Hz high-pass filter on the in-line power module helps control undesired low-frequency noise. The system also includes an AT8468 violin mount with hook-and-loop fastener and a protective carrying case. Features: Low-profile mic design for minimum visibility Crisp, clear, well-balanced microphone response, even at high SPLs Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source Unmount universal clip-on mount attaches securely to instrument bell and provides excellent shock resistance for the microphone Rugged Unmount 5" gooseneck rigidly holds its shape, keeping microphone accurately positioned even during aggressive play In-line power module is equipped with a switchable 80 Hz high-pass filter to control undesired ambient noise Interchangeable elements available for hyper cardioid and omnidirectional polar patterns Included violin mount with hook-and-loop fastener provides an additional mounting option Specifications: Element: Fixed-charge back plate, p....
