SOTAbeams LASERBEAM DSP Filter Modules
SOTAbeams LASERBEAM DSP Filter Modules work much better at reducing QRM than mechanical or analog filters. SOTAbeams applies special algorithm-based software to create well-defined passbands with steep contours. SOTAbeams offers their General Purpose, CW and SSB filter modules with switchable passbands. For example, the CW module (SBM-LB-MODULE-CW) may be used with either a 550 to 850 Hz passband, or a wider 300 to 1300 Hz passband. You choose the passband based on your own band conditions. Their SSB module (SBM-LB-MODULESSB) features passbands of either 300 to 2700 Hz or 300 to 2400 Hz. SOTAbeams designers have determined that these passbands work very well for SSB voice filtering. They offer their General Purpose filter module (SBM-LB-MODULE-GP) to accommodate both CW and SSB. These modules have selectable passbands of 550 to 850 Hz and also 300 to 2700 Hz. In this way you may limit CW or SSB QRM that is outside the selected audio passband. Be advised that these modules are NOT of the plug-in style. To use them takes some knowledge and soldering skill. You will also have to add an enclosure, if desired, as well as external parts not supplied with the PCBs. As designed, these modules will drive typical "low power" earbuds all by themselves. They will also drive audio amplifiers or amplified speakers. Note: Whenever the DX Engineering "Documentation" tab is available, please look at the associated files for additional product information. Are you tired of battling the QRM? Order SOTAbeams LASERBEAM DSP Filter Modules from DX Engineering to hold those signals at bay!

bhi Bypass Switch
bhi Bypass Switch is an audio bypass switch for the bhi Dual In-line and Compact in-Line DSP noise cancelling units, which don't have an internal audio bypass facility. When you switch the power off on these bhi units, the audio does not pass directly through to your external speaker. So, with the Bypass Switch, you can route the audio from your radio directly to your extension speaker without powering on your bhi unit. This can be particularly useful if you just want to listen to your radio without your bhi noise cancelling unit switched on. A single push-button switch on the Bypass Switch provides this facility. Press the button in and the audio routes through your bhi DSP noise cancelling unit (power on). Press the button again and the switch returns to the out position and the audio is routed directly from your radio and loudspeaker. bhi Bypass Switch features: * Complete audio bypass of bhi DSP unit * Latching switch: In--DSP audio, Out--Bypass audio * Four 3.5mm mono jacks * Two 3.5mm mono plug patch cables * Audio power 5 watt RMS max * Unit Dimension, WHD: 3.150 x 1.969 x 0.866 in.
