NES10-2MK4 5W Amplified DSP Noise Cancelling Extension Speaker
The bhi NES10-2MK4 amplified DSP noise cancelling extension speaker removes noise and interference from noisy speech signals, enabling you to have a much more enjoyable listening experience. The speaker is compact and easy to use and incorporates the latest high-performance bhi DSP noise cancelling technology. The three-position switch on the top of the speaker controls the following functions: "Off" (audio bypass), "On" (audio amplified) and "DSP" (noise cancelling on). The speaker has a 5W audio quality amplifier with 8 to 40dB of DSP noise cancellation across 8 user levels, and up to 65dB of tone reduction. The NES10-2MK4 requires 10 to 18V DC (500mA). The speaker has an integral 2M audio lead terminated with a 3.5mm mono jack plug and is supplied with a sturdy metal mounting bracket. There is a 3.5mm mono headphone socket on the side for headphone listening. The speaker is muted when headphones are used and this socket is headphone level only and will not drive an extension speaker. The NES10-2MK4 speaker is supplied with a rotary filter selection knob (you push into the back switch), two fixing screws, 4 self-adhesive rubber feet, user manual and a x 1030-FPL fused DC power cable with tinned bare ends (requires a DC power supply for this cable).
The NES10-2MK4 DSP noise cancelling extension speaker is suitable for use in a wide range of radio communication applications across all radio frequencies and is particularly effective in improving the voice quality in amateur radio and shortwave listening. The speaker can be used in a base station environment or used in a vehicle.
The "On" power LED illuminates red when power is applied, and turns green when noise cancellation is active. The overload LED illuminates if the audio input is overloading the speaker. The output level control allows you to adjust the audio output to suit your conditions.
