BHI 5W DSP Noise Cancelling In-Line Module, The bhi In-Line Module cleans up noisy signals and works with most radios and receivers. It comes with the latest bhi DSP noise cancelling technology, which brings improved audio quality to the listener when operating in noisy conditions across all radio bands. The audio is clearer and more intelligible as a result. The In-Line Module accepts speaker level audio and connects in between your radio and loudspeaker. The speaker audio is muted when headphones are connected, and when the unit is switched off the audio bypass feature routes the signal directly through to the loudspeaker. The In-Line Module is powered from a suitable 10 to16V DC power supply and has a three-position switch that turns the unit on and switches the noise cancellation on and off. The “Status” LED illuminates red when power is applied and changes to green when the noise cancellation is active. The unit has an audio input overload LED, an audio output level adjust control and comes supplied with a 3.5mm mono plug lead, fused DC power lead, User manual and 4 rubber feet.
