The NEIM1031 Noise Eliminating In-line Module incorporates the latest Digital Signal Processing (DSP) technology.
The NEIM1031 module allows easy DSP level and audio volume adjustment from its front panel.

• Fully Adaptive noise cancelling
• Noise cancellation typically 20dB
• User selectable noise cancelling levels
• Audio input socket
• Line level input and output
• External speaker socket
• Headphone socket
• Greatly improved signal to noise ratio
• Easy to install with adjustable mounting bracket
• Noise Cancellation on / off switch
• 12-28Vdc operation
• Input overload warning LED

Available with a variety of connections, allowing the module to easily be designed into new equipment, or retro-fitted to existing products. The module has an integral microcontroller, connected to a small keyboard assembly. The microcontroller and keyboard provide single button operation of all the module's functions. The button switches the noise cancellation on/off and changes the DSP noise cancellation level. In addition the unit stores the last used DSP level, so when power is re-applied the unit will default to the last used setting.

• Fully adaptive noise cancelling
• Minimum distortion to audio signal
• Noise cancellation 9 - 35dB
• 8 user-selectable noise cancelling levels
• Noise cancellation can be preset on PCB or remotely changed
• Wide audio bandwidth for natural sound
• Input and output level adjust.
• Input overload indication LED
• 5 - 15VDC operation
• Remote noise cancellation on/off
• Available in four configurations for easy system integration
• Ideal for Yaesu FT-817
