NEDSP1062: Amplified DSP module.

The NEDSP1062 module features the bhi noise cancellation DSP technology along with an integral power amplifier. Now you can fit noise cancellation into your speaker. Simple to fit, insert the module inline with the loudspeaker. Works with loudspeakers fitted with filters.




Yaesu SP-8




		Kenwood SP-31

In addition it 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.
The unit stores the last used DSP level, so when power is reapplied the unit will default to the last used setting.
When the module is switched off the audio bypasses the module and the speaker operates as a conventional extension speaker.

Detailed instructions for fitting the module into the Yaesu SP8 and the Kenwood SP31 are supplied in the operating manual, but it can be easily installed in most extension speakers.
