BHI NEIM Compact - Portable DSP

The NEIM-Compact is a smaller module for noise reduction by bhi, which uses two internal "AA" size batteries or external DC power. With the battery operation this module is particularly suitable for mobile or portable operations during a vacation. The NEIM-COMPACT takes a stereo or two independent mono signals, the actual noise reduction is done with thewell known DSP system by bhi. The greatly enhances the intelligibility of voice modulation, and reduces fatigue induced due to long listening durations e.g. on shortwave.

The NEIM-Compact module accepts either loudspeaker or line-out level input signals, on the output side a headphone or small loudspeaker can be connected. The operation is done very easy with two dial knobs for adjusting the volume and the filter levels. Due to the flexible design of input signals the module can be used with any type of radio or receiver, either classical or SDR type. The power supply is done either by two internal AA size alkaline or NiMH rechargeable batteries, or by supplying external 8 to 16V DC. Operating time with batteries is approx 40 hours, the device turns off automatically after one hour when not used.
