Fine tuning Linum cables with MMCX connection

The majority Linum users with MMCX earphones are happy Linum owners. In a few cases star washers are needed to establish the optimal connection. Star washers are included free of charge with all Linum MMCX purchases.
 
The MMCX is a connector system used in many high-end earphones and CIEMs as well as in many other applications. It is manufactured to very exacting standards by numerous companies however different tolerances mean that occasionally a misfit may occur between the plugs of different manufacturers.
 
A poor MMCX match may show as a feeling that the connection is “loose” in one or both channels, and/or occasionally intermittence. Installing a star washer or two will in most cases solve the poor connectivity and allow for true and uninterrupted use of your Linum cable.

 

INSTRUCTIONS FOR MOUNTING STAR WASHERS

Carefully remove the monitors from the Linum cable by pulling the plug (not the cable) and place the cable with the plug near you. Also keep the earpiece nearby.
 
The goal is to mount the star washer on the MMCX Male plug on the Linum cable in the correct direction.
 
Place some star washers on a table. Star washers are like miniature dinner plates. When it turns upside-down placed on a table it is stable. When it is the correct way up it is a bit unstable. Make sure the star washers are like an upside-down table.
 
When the star washer turns correctly on the table (=stable), press down gently on a star washer with a slightly moisten finger to pick it up. Holding it on your finger upwards, it is to be positioned as a plate (ready for food).
 
With the other hand, hold the cable with the plug turning up and carefully place the star washer on the plug. Holding the plug upwards, the star washer is like an upside-down table when mounted correctly.
 
Use the earpiece or a drinking straw to press the star washer into place. Same procedure for the other plug if required.
 
Test to see if the connection is improved. If it still feels loose or intermittence is detected, mount a second star washer with the same procedure.
 
If the star washer solves the problem, then all is good, and we hope you will enjoy your Linum cable.
