KAB Record Grip™ Record Clamp         


SPECIFICATIONS   This simple but effective hard phelonic record clamp fits most unthreaded platter spindles.  The KAB Record Grip™ is effective at damping resonances and improving bass response and imaging focus. With a base of non-marring UHMW polyethylene, the KAB Record Grip™ is gentle on your record labels and makes firm contact. The inset level is helpful in ensuring that your turntable is perfectly level so that it can operate properly.  This is a great accessory for turntables that do not come with a record clamp.  Since the KAB Record Grip™ must be pushed down to install, care should be exercised when using it with suspended or sprung turntables.

KAB GSE PreconLP Inverse RIAA Level Convertor™

The PreconLP™ is a passive (no electricity required) device that is designed to convert a line level signal to a phono level signal with the proper inverse RIAA response characteristics. It is highly accurate, and it has several useful applications for the audio hobbyist.  Used with a CD player and an appropriate burn-in CD, the PreconLP™ can provide a burn in signal for your phono preamp.  Used with a test signal generator, the PreconLP™ can provide a reverse RIAA signal suitable for testing the accuracy of any phono preamp.  The PreconLP™ can also be used to convert an unused phono input into a spare line input.  The output level adjusts automatically for MM inputs and MC inputs.  When sourced into a 47K load the output level will match moving magnet cartridges; when sourced into a 100 ohm load, the output level will match low output moving coil cartridges.

KAB GSE Stereo Canceller™

The GSE Stereo Canceller™ is designed to sum the two stereo channels out of phase.  This cancels all of the sound produced by lateral stylus movement and leaves all sound produced by vertical stylus movement.  Used with a mono recording, the Stereo Canceller™ can be used to optimize phono cartridge azimuth by adjusting for maximum cancellation.  With a stereo cartridge and proper stylus, the Stereo Canceller™ can be used to listen to vintage vertical cut recordings like Edison Diamond Discs, Pathe Needle Cut Records, and World Transcription Recordings.  The Stereo Canceller™ can also be used to confirm stereo to mono compatibility as might be required in broadcast environments.  The Stereo Canceller™ uses a high quality fully shielded center tapped audio transformer to passively sum the two inputs out of phase. The output is taken from the secondary and applied to both output connectors.
