The bhi DSPKR DSP noise cancelling speaker from bhi really lets you hear the signal. Thisspeaker comprises a wide frequency range 4” speaker and an audio amplifier capable of producing up to 10-Watts RMS audio power, with DSP a built in bhi DSP noise cancelling filter. It is suitable for use where noise and interference mean that you cannot clearly hear what is being said, and it will enable the user to hear the signal “stress free”. Suitable for mobile and base station use in: ham radio, CB radio, two-way radio, HF radio, and marine communications. The DSPKR has up to 7 DSP filter levels, allowing the user to optimise the unit for their level of noise and interference.

It simply connects into the extension speaker socket or headphone socket of your radio and all the controls are on the top of the speaker for ease of use. The unit has a separate “VOLUME” control, an “AUDIO LEVEL” indicator, and requires a signal of between 80 and 500mV for optimum performance.

The “STATUS” led indicates whether the noise cancelling is on or off, and when the “ON/FUNCTION” button is pressed momentarily, the unit steps through the 7 noise cancelling levels until the desired level is reached. This level can then be stored by pressing the FUNCTION button for a few seconds.

The DSPKR can be preset for 4 or 7 filter levels. The unit has a sleep mode to save on power when not in use, and requires a DC supply of between 10 and 18 Volts (2A).

The unit is supplied with a 3.5mm mono jack plug lead 2 metres long for the audio input, and a 2.1mm fused DC power lead with bare ends. A 3.5mm mono auxiliary output socket is also provided to allow the speaker to be used with headphones or to drive another loudspeaker.
