Compact In-Line
Compact In-Line stereo/dual channel DSP noise cancelling module

The New Compact In-Line module measures just 125 x 70 x 37 mm, and is the latest addition to bhi's range of DSP noise cancelling products. 

This small compact battery operated handheld unit is ideal for portable use, and includes the latest bhi dual channel/stereo DSP noise cancelling technology. It is designed to be used with a pair of stereo headphones, but will also drive a mono loudspeaker or a pair of powered stereo speakers.

The Compact In-Line module is powered by two AA alkaline or NiMH batteries, or can be powered from a separate DC supply (power lead supplied). The modules functions are microprocessor controlled and the unit can accept mono or stereo signals. It has separate speaker level and line level inputs with two separate rotary encoder controls with pushbutton action for filter level select, power on/off, volume control and stereo/mono signal selection. You simply adjust the controls to suit your current noisy conditions. This module is suitable for use on all radios and receivers including software defined radios (SDR).
