bhi NES10-2MK4 5 W DSP speaker
5 W amplified speaker with 8–40 dB DSP noise cancelling, 65 dB tone reduction, metal bracket, base or mobile use
The bhi NES10-2MK4 is a compact 5 W amplified speaker with DSP noise cancelling from 8 to 40 dB: it removes noise and interference from voice signals, with particularly good results on amateur radio and shortwave.
Product description
The three-position switch on top selects Off (audio bypass), On (amplified audio) and DSP (noise cancelling active). The rotary knob selects one of 8 filter levels; tone reduction reaches 65 dB.
The power LED is red when powered and turns green with DSP active; a second LED indicates audio input overload. The output level is adjustable.
It has a built-in 2 m audio lead with a mono 3.5 mm jack and a sturdy adjustable metal bracket: use it in the shack or in the car. On the side there is a mono 3.5 mm headphone socket; plugging in headphones mutes the speaker.
Key features
Adaptive noise cancelling, 8 levels.
Adjustable amplified audio.
Adjustable metal bracket.
Note
The headphone socket is headphone level only and does not drive an external speaker. The power lead has bare ends: a 10–18 V DC supply is required.
