BHI NEDSP1901-KBD - DSP noise cancellation module

The NEDSP1901-KBD is a low-level audio DSP noise cancellation module that can be installed in many transceivers and readio receivers. It is a direct replacement for the popular discontinued NEDSP1061-KBD module . This pre-wired DSP noise cancellation module incorporates the latest bhi DSP noise cancellation technology and provides up to 40 dB of noise cancellation to dramatically improve noisy speech signals. The module is controlled by a single button with LED and audible indication for ease of use. It comes as a pre-wired retrofit style module and can be integrated directly into the low-level audio path of your receiver, transceiver or audio system, offering excellent DSP noise cancellation and greatly improved voice quality. The module features DSP on/off and up to 8 levels of DSP filtering via a small push button interface board. The module is supplied with a mounting kit and general installation instructions, as well as specific mounting guides for Yaesu FT-817/FT818 (same information for FT-817), Kenwood TS-50 and Icom 706 MK II G .

For commercial HF radio applications, the basic NEDSP1901-PCB module is probably best suited.

Installation information : Only four wires are used to connect the module to the audio circuit of the radio/receiver: Audio In, Audio out, 0V and Power. All that's left to do is drill holes to accommodate the switch assembly and label. Mounting kit supplied.

Yaesu FT-817/818 Note: Unlike the previous NEDP1061-KBD DSP noise cancellation module, this new direct replacement only fits the front position of the Yaesu FT-817/818. If you have extra filters installed in your FT-817/818, you cannot fit the NEDSP1901-KBD module inside your radio. In this case you might want to consider the new NES10-2MK4 compact DSP noise canceling speaker .

For commercial HF radio applications, the basic NEDSP1901-PCB module is probably best suited.
