Remove noise and hear clearly with this fully featured DSP noise cancelling unit
Flexible DSP noise cancelling unit with high-performance audio processing - New lower Price!
The bhi Dual In-Line amplified DSP noise cancelling module uses a powerful high-performance audio processing system and unique DSP noise cancelling technology to distinguish speech signals from noise and interference. This results in clear intelligible speech under most conditions. Your listening experience will be greatly improved with the processed speech sounding much clearer and more intelligible without all the noise, especially when trying to listen to weak signals.
Easy to use controls
The Dual In-Line is easy to use with simple rotary controls and switches. There is an input level control with LED's and separate output level controls for adjusting the line level and speaker output levels. You can listen with headphones, a passive mono speaker or powered speakers. Operation of the noise cancelling is straightforward with filter on/off switch and an 8-position rotary switch to set the of noise filter level. There is also a switch which allows you to separate or combine the input signals.
Choice of connection options
The Dual In-Line has accepts 3.5mm mono or stereo connections and there are three different output sockets; 7 Watt mono speaker output, stereo line level output and a 3.5mm stereo headphone output. This flexibility enables you to connect up to two mono inputs or one stereo input, and up to three separate outputs.
Suitable for use with all radios, receivers and SDR
The Dual In-Line module caters for both mono/stereo speaker level and stereo line level audio input signals. Powered speakers can be connected to the stereo “Line Out” socket, and a passive speaker can be connected to the 7W amplified mono “Audio Out” socket. You can listen with headphones and a mono speaker at the same time, making the unit ideal for DXing, club stations, special event stations and field day events. The Dual In-Line module is a direct replacement for the obsolete bhi NEIM1031MKII but with the latest bhi DSP noise cancelling technology and more features.

"Having to wear hearing aids I find the noise reduction excellent. I can now take away noise and read stations that without the Dual In-Line I would not be able to communicate with. Having used the NEIM1031 for many years the improvement is very good. The build is also improved. Very pleased with my Dual In-Line"

"Reduced background noise. Super product, many thanks" Mr T Hayman
"Unbelievable! Noise gone! Other products don't compare. Your new Dual In-Line allows me to monitor 2 sep-arate frequencies with my reciver as it has 2 vfo's, comms from each speaker are c;ear, as if my volume is down. Perfection. Graham has gone out of his way to assist me, even sending replacement parts on older products, N/C! thank you, Ron" Ron Monfeli
